#Logarithm without base

[vintagerpg]

What a fun and welcoming box set! This is the second edition of DC Heroes (1989) from Mayfair games. I’ve never encountered the first edition, but my impression of this box is as an attempt to make a fairly tricky system as welcoming and accessible as possible without, you know, tossing out the original system. Which is a clever system, based on logarithms — the same thing is under the hood of Underground. I understood it for a brief moment in time despite my deficiencies in math (but lordy, no, I did not retain it, nor do I wish to re-learn), and it struck me as a clever way to handle the divergent power levels present in a superhero game. It is, however, clearly not as user-friendly as, for instance, TSR’s Marvel RPG.

There’s a lot in the box — a brief intro pamphlet with a solo adventure, a rulebook for the GM, a player’s guide, a screen, a group adventure featuring the Justice League International, a little wheel that makes resolving rolls much easier (not quite so easy as the Universal Table in Marvel, but close). There’s a beefy dossier of characters accompanied by a stack of full-color character cards, which are a nifty, fidgety addition that doesn’t really add much to play.

The 15-page chapter on running games has some of the best advice I’ve encountered from the period — focused on collaborative play, encouraging roleplay and generally putting fun ahead of rules. One section has the header “You are the Player’s Senses” and I think that might be one of the best summaries of the GM’s role I’ve ever read. It certainly feels miles ahead of just about anything else from the period that comes to mind, with the possible exception of Rolemaster’s Campaign Law.

This box wants so desperately to be a game anyone can play. I don’t think it quite gets there, but I think the way it tried was influential — over the course of the ’90s, we’d start to see more and more supportive text in RPG books that sound like they spin right out of this GM’s section.

For many years there has been intense discussion on the role and legitimacy of the jury vs the televote in the Eurovision Grand Final. The problem is that many of the arguments I see made are based on nothing but people's gut feeling and snap judgements from watching the show. And humans are notoriously terrible at intuiting statistics.

That's why I wanted to provide some actual data to give context to the more eye-catching examples people tend to use, and hopefully encourage some critical thought. I spent the afternoon updating my eurovision excel file with data from the 2024 and 2025 Grand Finals, and can now present these graphs of jury results plotted against the televote. As far as eurovision statistics go, this is one of the simplest charts you could make, and should hopefully be as simple to understand.

Terms: I use the term televote to refer to the entire public vote - this includes all votes from calls, texts, websites etc.

The axes: These show percentages out of the total number of jury or televote points awarded overall in a given show. Using this measure instead of the actual point scores ensures that results from different years are comparable, despite the fact that the number of Grand Final entries and overall points to be distributed between them varies from year to year (depending on the number of voting countries) .

Reference line: This shows where an entry would land if the juries and televote respectively awarded it an equal percentage of their available points. Data points that land above this line means the jury awarded the entry a greater proportion of its available points as compared to the televote, and vice versa. I find it interesting to see which entries land near this line, and then compare them to entries that stray further from it, in either direction. I also like to see where my favourites ended up, and consider how that can be understood in the context of the previous comparison.

First chart: Here each data point represents an individual entry in the Eurovision Grand Finals from 2016 to 2025 (aka every year with the current split scoring system). Data source: eurovisionworld.com

Second chart: These data points represent the average percentage out of the total jury/televote points each country was awarded between 2016 and 2025 (for the years that they made it to the Grand Final, that is).

Beware: For countries that made it to the final more times there are more data points to average, while for others there are as few as two results to work from.

Also beware: Averages can obscure variance - a country with epic highs and lows might end up looking similar one with stable middle-of-the-road results, despite their actual experiences being very different. That is to say: there are lots of outliers included in these averages - Spiders Georg has set up his cave and now lives in this chart. With his entire spider farm. Look at it. It's on the web.

Also-also beware: This chart makes the assumption that nationality is the most relevant variable to investigate in relation to the final result. But that remains an unproven assumption; before drawing any conclusions about potential biases the public or juries might have for certain countries, these results should be compared to charts where other factors are accounted for, to rule them in or out as compounding factors. Such factors could be running order, when the voting opens, genre, vocal ability, dancing ability, stage precence, visual production, creative cohesion etc.

In short, this chart doesn't rule anything in or out on its own—but it makes a good starting point for further investigation.

Country letter codes, for reference:

Not sure how viewable these charts will be on smaller screens, but for the lower scores on the detailed breakdown to be visible at all I needed to make them huge. Might fuck around and make the scale logarithmic at some point, to show more detail in the lower range without cutting off the upper. I also have more data tables with more complex calculations going on in this excel file. I might make charts of those at a later date, if I can first work out whether they provide any useful insights at all or were just fun to make. ¯\_(ツ)_/¯

Thanks for reading!

Physics "Friday" #9 [OPINION]: Is Fahrenheit the better temperature scale?

So as the title suggests, this post is a lot less facts and logic, and a lot more opinionated. It is still physics-y I just believe it's an interesting way to delve into a subject by turning it into an opinionated peice.

Preamble: A summary of Metric vs. Imperial arguments

Education level: Primary (Y3/4)

Topic: Measuring Systems (Metrology)

Now before you throw your hands up at the title and your silly little internet brain is like "this silly impericuck is fahrenpilled!" ... I'm an astronomy student living in Australia - I use SI units (and other unit systems) on the daily.

Though ... it is pretty notorious in astronomy to use like 17 different unit systems. Here's a list of examples:

My beloved SI units

CGS Units

Whatever the fuck a Jansky is

Don't even start with natural units I can't live without big G

"Ampere in CGS units is g1/2 cm3/2 s−2"

Solar Luminosity/Mass of Sun

Angstroms (like please can we just use nanometers?)

How many Jupiters or Earths fit into this cloud of gas?

The vomit of parallax units i.e. AU, pc, Mpc, arcseconds, radians

Steradians (Solid angles can be finicky)

Logarithms, logarithms everywhere!

Hubble's constant being in km/s/Mpc but then having to turn that into Hz or per year - like can someone please acknowledged how cursed this is?

When you do Kepler's 3rd law on Mercury and realise it doesn't work (because you forgot Einstein existed) ... so no units end up working

ADUs and/or whatever you get when you deal with telescope outputs

And as an Australian, I use SI units very regularly. Only measurements of human height and cooking weights are really imperial. And I can express all of them in metric units.

Now generally, the Metric (or SI) units are better than the imperial (or USC) units. The main points in favour of SI are:

(Almost) Everybody uses it

It's basically universal in science (see exceptions above)

It fits well with our base 10 counting system, easy scaling (e.g. 1 kg = 1 000 g = 1 000 000 mg)

It's directly pinned to many natural constants and unchanging laws

Different units interact with eachother much better

Now, generally, the main arguments for imperial units involve a bunch of patriots™ screaming about how "THIS IS THE CoUNTRY OF FREEDOM AND GOD!! AND I AIN'T USING NO CHINESE UNITS!!!1!".

That, or how metrification is hard. Which, well, metrification can occur over the course of decades, literally teaching your kids metric helps the country adjust to a metric system.

The best arguments I've found for imperial units is as follows:

Numbers like 6, 12, 60 etc. - i.e. units based on highly composite numbers - are very easily divisible by 2, 3, and 4

Units like feet, inches, pounds, stone, etc. are of a much more human-friendly scale. Because these units are based on bodily proportions or common objects

Generally, the arguments for metric vastly outweigh the arguments for imperial. And the main reason why is that the two arguments for imperial conflict with eachother. You cannot easily subdivide your units neatly and have human units.

For example, the Roman mile is a unit that measures the usual amount of distance a footsoldier can cover before needing a short stop. An acre is the amount of land that a manual-labour farmer can cover in a day's work. An inch is about the size of your thumb.

The problem is that all three of these units, based on length, are completely off kilter. 1 acre = 43,650 square feet, 1 Roman mile = 58260 in, etc.

The only cases where I would say the human-ness and divisibility of units actually becomes a stronger argument than decimalised units are, time and temperature.

Time is obvious. 1 hour = 60 minutes = 3600 seconds. It's nice, clean and simple. And an hour or half-hour is a very human unit, the same as a second or a minute. We often operate on hour and minute schedules, and that's not just because of capitalism. 30 minutes just appears to be the amount of time we like to work before taking a short rest.

Temperature is a bit more nebulous however ...

Where (I think) Celsius fails

Of course, celsius is an understandable scale. 0 C = Water Freezes, 100 C = water boils. Pinning your scale on water makes life easy for you as you know what the bounds are.

The problem is that there are temperatures that exist outside of the 0-100 scale. And this kinda breaks the neat decimalisation of a scale.

A cold winter's day in Tasmania could drop into the negatives. And just because your in the negatives doesn't mean ocean water or rain will freeze. Temperatures below 0 C doesn't guarantee snowfall.

Similarly, say you are in a desert during the day. The temperature can get as high as 50 C - it's reasonable to say that you're unlikely to see temperatures above 50 C outside of your oven or kettle.

Do you normally see temperatures between 70 - 90 C? Unless if you're pasteurising milk, distilling alcohol, or doing chemistry, you are not going to encounter these temperatures. And do you really need your temperature numbers to be below 100 to do chemistry?

This is the downside of Celsius. Because temperature is a scale, and operates differently to other units, it doesn't really matter where you set the zero point. A boiling point of ethanol at "78" is no better than one at "173".

Celsius also doesn't account for temperatures that are very well below the freezing point of water, temperatures which are very common to experience.

So is Fahrenheit Better?

Fahrenheit solves this problem, partially. It's a more human friendly scale. 0 F is a very very cold day whereas 100 F is a very very hot day. Things beyond both numbers are relegated to the scientists, chefs, and extremophiles of the world.

If we were to completely remove all requirements of not pissing off a bunch of people, we could even create our own temperature scale to make things even better: 0 X = -50 C and 100 X = 50 C.

Even better because now the 0 and 100 of this scale becomes the absolute limit of what we could normally experience on earth, the hottest desert and the coldest tundra. It even comes with the benefit that 50 X = the freezing point of water and 150 X = the boiling point of water - it preserves our common "anchors" of the phases of water.

The problem is that there's a second hidden benefit of Fahrenheit: it's specificity. What do I mean by that?

Well, for every 1 C increase in temperature, the Fahrenheit scale increases by 1.8 F. This means that a temperature of 20 C could mean 68 F or 69 F.

For a lot of normal/casual processes, the Celsius scale may require us get past the decimal point, to express minor changes in temperature, whereas Fahrenheit would not.

For chemistry and physics, our significant figure requirements immediately become extra precise. 58.8 F is a more accurate measurement than 14.9 C, without requiring any more decimal places.

You may say "well why not we use a deci-Celsius scale where 1000 dC = boiling point of water". The issue is that too much precision may be putting it over the top. We don't measure the size of cities in centimetres.

But then what about Kelvin

Of course, the main SI unit for temperature, and the unit physicists and chemists use is the Kelvin. The reason for this is of course:

It is tied to absolute zero by setting it to 0 K

Because of this, we can apply SI order of magnitude quantifiers like milli-Kelvin, kilo-Kelvin, Giga-Kelvin without upsetting the position of our anchor points

It covers and measures cleanly low-K processes

Very hot processes end up having Celsius be approximately equal to Kelvin

It would be difficult to use Fahrenheit because 0 F ~ the freezing point of saltwater.

But let me introduce you to the Rankine Scale. What Kelvin is to Celsius is what Rankine is to Fahrenheit.

Rankine takes all of the benefits of Fahrenheit with it (aside from the human-ness of the scale - but that's not the purpose of the Rankine and Fahrenheit scales), but it also takes the benefits that Kelvin gets.

We can too, have milli-Rankine and Giga-Rankine. And the best part is that it is twice as precise as Fahrenheit.

Even better is that the Rankine Scale is very easily convertible to the Kelvin Scale. 1 K = 1.8 R; 1 K⁻¹ = 0.556 R⁻¹. This means I can very easily re-formulate some fundamental constants:

Boltzmann constant = 1.381 × 10⁻²³ J K⁻¹ = 7.672 × 10⁻²⁴ J R⁻¹

Stefan-Boltzmann c. = 5.67 × 10⁻⁸ W m⁻² K⁻⁴ = 5.40 × 10⁻⁹ W m⁻² R⁻⁴

Ideal gas constant = 8.315 J mol⁻¹ K⁻¹ = 4.619 J mol⁻¹ R⁻¹

Wein's constant = 2.898 × 10⁻³ m K = 5.216 × 10⁻³ m R

Let's hope I converted it correctly, idk my Saturday brain no thinky.

Conclusion: So is it actually better?

Short Answer: In my opinion, yes. But I'm not switching to it.

Of course, when talking about subjective opinions, people can point out the flaws in each others' opinions. I've made it clear that the imperial vs. metric debate very solidly falls to the metric side with only a few exceptions.

Temperature is one of those scales that are more up-to-debate over the usefulness of certain units of choice. Especially because the alternative unit system is still commonly used.

I could've made the same arguments about the meter, and said that we should use a decimalised inch or foot with kilofeet or millifeet. Or invent a completely new unit system that is technically "superior". But that's obviously much more ambitious.

Of course, the likelihood of the global Fahrenheit revolution is almost non-existent, and this is more of a series of "well, technically speaking" arguments that are more for the point of exploring an idea than implementing one.

Regardless I'd like to hear YOUR arguments over why I'm a stupid poo poo head or I'm actually the mother of the next great napoleonic French empire.

I tried to add a bit of colour in this post, specifically with the quotes. I just didn't want it to be a bland wall of text.

Again, feedback that may be unrelated to the specific "you're right/you're wrong" debate like my writing style etc. is also appreciated.

I don't really know what I will do next week. Because technically I was supposed to do philosophy and ethics in science ... but I might not have that time given my university study.

Currently I'm doing three courses in QFT, GR, and Cosmology. And they are all very big and hefty. Thankfully, I think there's a bit of a break period coming as we're now moving to canonical quantisation (which I've found easier than Feynman diagrams), and the measurement of gravitational waves.

Now don't worry that last paragraph is not a flex, it's more an indication that I'm learning a lot of this stuff as I make these posts. More an excuse as to why I might in the future delay posts and such. Like I mentioned the Higgs mechanism in the last post at the same time I was actually learning about the Higgs mechanism.

Anyways, I'm going to go and scarf down some chocolate now.

Why Calculus Puns Are an Integral Part of Math Humor The Derivative of Good Math Jokes Good math jokes, particularly calculus puns, thrive on clever wordplay and unexpected twists on familiar mathematical concepts. These jokes range from simple puns to elaborate setups requiring basic calculus knowledge. Consider the function that refuses to argue because it doesn’t want to reach an inflection point—a perfect example of calculus humor that connects mathematical principles with everyday situations. Math enthusiasts often gravitate toward pi-related jokes, with many calculus students claiming pi as their favorite dessert. The beauty of calculus humor lies in its ability to transform complex concepts into accessible jokes that even those with limited mathematical background can appreciate. How Calculus Puns Help Students Learn Calculus puns serve as valuable educational tools by making this challenging subject more approachable and memorable for students. These mathematical jokes effectively reduce stress levels and boost engagement when tackling complex topics like derivatives and integrals. Teachers who incorporate humor into their lessons create a more positive learning environment where students feel comfortable exploring difficult concepts. Educational resources from websites like Cuemath and Punsvila offer collections of calculus jokes specifically designed for classroom use. The connection between humor and retention is particularly strong in mathematics—students who laugh at calculus jokes are more likely to remember the underlying concepts during exams. Making calculus fun through puns transforms it from an intimidating academic pursuit into an captivating intellectual adventure that students actually look forward to experiencing. Prime Examples of Calculus Puns That Will Make You LOL Derivative Jokes That Are Off on a Tangent Recycled calculus puns are often called “derivative humor” due to their repetitive nature, much like taking the derivative of a function. A standout example that always delivers is “What’s the derivative of Amazon? Prime Rib!” – cleverly playing on Amazon Prime rather than the traditional cow version. Newton and Leibniz’s historical rivalry provides rich material for derivative jokes, such as “Newton: I’ve discovered calculus. Leibniz: Me too. Newton: Seems derivative.” Soccer apparently isn’t popular among calculus students because they’re “too many tangents” – a playful reference to lines that touch curves at single points. We’ve all experienced conversations that suddenly veer off topic, just like the student who said, “I had a good discussion with my calculus professor, but it went off on a weird tangent.” These puns work brilliantly as they connect mathematical concepts with everyday situations that anyone can relate to. Integral Humor for Advanced Functions Students particularly connect with the existential humor in puns like “Why was the calculus student always stressed? Too many variables in life.” Functions apparently have feelings too, as evidenced by “Why did the function refuse to argue? It didn’t want to reach an inflection point” – a clever nod to critical points where curves change behavior. Everyday objects become perfect vehicles for calculus humor. Elevators are praised by math enthusiasts “for understanding rates of change,” while roller coasters demonstrate “concavity and inflection points” in action. Assignments struggles inspire classics like “What’s long, hard, and scary? Calculus assignments!” Students seeking rest might justify their naps by saying they need “to integrate rest” – perfectly merging mathematical terminology with relatable college experiences. Even divine intervention isn’t safe from calculus wordplay, with puns like “When God integrated Earth, he added the sea.” Pirates apparently “excel at calculus because they never forget the C” – referring to the constant of integration that students often overlook. These crossover jokes extend to video games (“Integral of Duty”) and automotive troubles (“Why did the car break down? It hit a critical point”), proving that calculus humor can derive laughs from virtually any situation. Calculus Puns for Those Who Like to Live on the Edge (of a Graph) Historical and Academic Context Calculus puns have been making mathematicians chuckle for generations by cleverly incorporating concepts like derivatives, integrals, and limits. One classic example we love is “Drinking and deriving,” which brilliantly plays on homophones to blend calculus terminology with everyday activities. The famous rivalry between Newton and Leibniz over who discovered calculus first has also spawned many jokes, including Newton’s witty comeback: “Really? Seems derivative.” Common Themes in Calculus Humor Wordplay forms the foundation of many calculus jokes. “Derivative humor” refers to recycled jokes that lack originality, creating a clever mathematical metaphor. Another favorite is “Don’t be mean, integrate!” which transforms mathematical operations into life advice. Love and Relationships provide fertile ground for calculus puns. Couples with a mathematical bent might express their feelings with lines like “Our love is exponential” or “You’re my prime factor,” blending romantic sentiments with mathematical precision. Student Struggles often appear in calculus humor, reflecting the challenges many face when learning this subject. A prime example is: “What’s long, hard, and scary? Calculus assignments.” Notable Examples That Differentiate Great Puns The Pirate Joke remains a staple in calculus classes: “Why are pirates the best at calculus? They never forget the C.” This cleverly references the integration constant (+C) that students often omit. Visual Humor works particularly well with graphing concepts: “Why did the graph go to therapy? It had too many ‘ups and downs'” – a pun that perfectly captures both emotional states and function behavior. Exam Stress provides relatable material for students: “I failed my Calculus exam because I was seated between identical twins—it was hard to differentiate.” This pun brilliantly connects the mathematical concept of differentiation with the everyday meaning. The Function of Calculus Humor These mathematical jokes do more than just entertain—they simplify complex concepts, making calculus more approachable for students who might otherwise feel intimidated. Many calculus puns serve as excellent mnemonic devices, such as “integrate now, differentiate later,” helping students remember key processes. How to Use Calculus Puns in the Classroom Without Approaching the Limit of Student Patience Know Your Audience Matching calculus puns to your audience is crucial for effectiveness. Students with different mathematical backgrounds will appreciate different levels of humor, so ensure your puns aren’t overly complex for beginners. First-year calculus students might enjoy simpler jokes like “Why is the south bad at calculus? They don’t know how to integrate,” while advanced students can appreciate more nuanced mathematical wordplay. Perfect Your Delivery Delivery transforms even recycled derivative humor into something fresh and captivating. Present your puns with genuine enthusiasm and appropriate timing to maintain student interest. A well-timed calculus joke during a particularly challenging lesson can reset attention and create a moment of connection with your class. Teachers who deliver puns confidently often find students more receptive to the mathematical concepts that follow. Use Moderation Strategic placement of puns prevents overwhelming your students with too much humor. We recommend using a few well-chosen jokes rather than turning every concept into a pun opportunity. Spacing out your mathematical wordplay across a lesson helps maintain the novelty factor without distracting from essential learning objectives. Consider introducing a calculus pun like “Why did the calculus student bring a ladder to class? To reach new heights in calculus” when introducing a new or difficult topic. Encourage Student Participation Inviting students to create their own calculus puns fosters engagement and creativity. This approach transforms passive listeners into active participants in the learning process. Student-generated humor often resonates more deeply with peers and creates memorable associations with mathematical concepts. Classes that collectively develop their own mathematical jokes often demonstrate stronger community bonds and increased comfort with challenging material. Connect Puns to Learning Objectives Effective calculus puns directly relate to the concepts being taught. Jokes about integration should appear during integration lessons, while derivative humor works best when discussing differentiation. Teachers might incorporate the “integral twist” dance move when explaining integration techniques, creating both a visual and verbal memory aid. Relevant humor reinforces key concepts and helps students recall important information during assessments. When Calculus Puns Converge: Math Jokes for Different Skill Levels Mathematics humor appeals to different audiences based on their familiarity with calculus concepts. We’ve collected some of the best calculus puns categorized by complexity to ensure everyone from beginners to advanced mathematicians can enjoy a good laugh. Simple Calculus Puns These entry-level jokes require only basic knowledge of calculus terminology, making them accessible to most math students. Derivative Humor: What do you call a recycled calculus pun? Derivative humor! This joke plays on the dual meaning of “derivative” as both a mathematical concept and something unoriginal. Too Many Variables: Why was the calculus student always stressed? Too many variables in life! Anyone who’s struggled with complex equations filled with x, y, and z variables can relate to this simple yet effective pun. Calculus Assignments: What’s long, hard, and scary when you first see it? Calculus assignments! This pun perfectly captures the initial intimidation many students feel when facing a new calculus assignment. Mid-Level Jokes These puns require a slightly deeper understanding of calculus principles but still remain accessible to most students who’ve completed an introductory course. Space for Differentiation: Why did the calculus student break up with their partner? They needed more space to differentiate themselves! This cleverly connects the mathematical concept of differentiation with personal growth. Elevators and Rates of Change: Why do calculus students love elevators? They understand rates of change! This pun links the everyday experience of elevator movement with the fundamental calculus concept of changing values over time. Advanced Humor These sophisticated jokes appeal to those with a comprehensive understanding of calculus history and complex concepts. Newton vs. Leibniz: Newton: I’ve discovered calculus (1664). Leibniz: I’ve discovered calculus (1670s). Newton: Really? Seems derivative! This historically based pun references the famous priority dispute between Newton and Leibniz over who first invented calculus. Roller Coaster Mathematics: Why did the calculus student love roller coasters? They were all about concavity and inflection points! Students familiar with analyzing curves and their behavior will appreciate this connection between thrilling rides and mathematical concepts. Math humor serves as an excellent bridge between abstract concepts and relatable situations. These calculus puns demonstrate how mathematical principles can be found in everyday experiences, making the subject more approachable and captivating for learners at all levels. The Chain Rule of Comedy: Creating Your Own Calculus Puns Calculus puns thrive on clever wordplay involving mathematical concepts that can transform complex formulas into laugh-out-loud moments. We’ve compiled essential strategies to help you create your own mathematical jokes that will differentiate you from other comedians. These techniques leverage the rich terminology of calculus to create humor that both math enthusiasts and casual jokesters can integrate into their repertoire. 1. Terminology-Based Puns Mathematical terms often have everyday meanings that create perfect opportunities for wordplay: “Drinking and deriving” cleverly substitutes “driving” with “deriving,” warning against calculating derivatives while intoxicated “Derivative humor” pokes fun at recycled jokes by referencing how derivatives are derived from original functions “Stay in your limits” transforms ordinary advice into a mathematical reference about boundaries in calculus These puns work because they bridge the gap between technical jargon and common expressions, making them accessible to wider audiences. 2. Conceptual Wordplay Take advantage of the metaphorical potential in calculus concepts: “Our love is exponential” replaces typical romantic growth metaphors with a mathematically precise function “You’re my absolute value” romantically suggests someone always makes everything positive, just like the absolute value function “Tangents are just the TIP of the curve” plays with both the mathematical meaning and conversational notion of going off on tangents This approach connects emotional or everyday experiences with mathematical principles, creating relatable humor with an intellectual twist. 3. Pop Culture & History Incorporating historical figures and pop culture references adds depth to your calculus humor: Newton vs. Leibniz rivalry: “Newton: Really? Seems derivative.” cleverly mocks their famous dispute over calculus invention Pirate mathematics: “A true pirate never forgets the C” reminds students about the crucial integration constant “Mathemagician” combines “mathematician” and “magician” to suggest the seemingly magical nature of calculus answers These references appeal to those familiar with calculus history while remaining approachable to newcomers. 4. Formulaic Structures Apply traditional joke structures to mathematical content: Question-and-answer format: “Why did the graph go to therapy? It had too many ups and downs“ Self-referential humor: “Calculus jokes are all derivative” playfully critiques the repetitive nature of math puns This framework leverages familiar joke patterns, making complex concepts more digestible through humor. To create your own calculus puns, identify terms with dual meanings (like “integrate” which means both to socialize and to calculate) or find phonetic similarities (“pi” vs. “pie”). Then combine these mathematical elements with everyday situations like relationships, school, or work to create universally appealing jokes that don’t require an advanced degree to appreciate. Try crafting your own puns using this formula: Term: Limit → Pun: “My patience has reached its limit… and it’s approaching infinity.” Concept: Chain rule → Pun: “Our friendship follows the chain rule—always connected, never broken.” The best calculus puns transform intimidating mathematical concepts into accessible humor, proving that even the most complex subjects can become sources of joy and connection. Calculus Puns That Professors Secretly Love Professors might maintain a serious demeanor in the classroom, but they’re often harboring a deep appreciation for calculus humor. We’ve gathered some of the most professor-approved mathematical jokes that bring smiles to even the most stoic academic faces. Wordplay on Mathematical Constants Mathematics instructors particularly enjoy puns that cleverly incorporate fundamental calculus concepts. “Why are pirates great at calculus? They never forget the C” ranks among faculty favorites, with the integration constant (“C”) serving as the perfect punchline. Professors appreciate this joke because it reinforces a common student mistake while being genuinely funny. Derivative Humor Nothing gets a calculus professor chuckling like a good derivative joke. “What’s a recycled calculus pun?

Quantum Computing in Cybersecurity

Quantum computing is emerging as a transformative force in the field of cybersecurity. Unlike classical computers, which rely on bits, quantum computers use qubits—units that can exist in multiple states simultaneously due to the principles of superposition and entanglement. These unique capabilities allow quantum computers to perform certain calculations exponentially faster than traditional machines, posing both unprecedented opportunities and serious threats to modern cryptographic systems.

One of the most significant impacts of quantum computing lies in its potential to break widely used encryption methods. Algorithms like RSA, ECC (Elliptic Curve Cryptography), and DSA underpin much of the world’s digital security. These algorithms are based on problems that are hard for classical computers to solve, such as integer factorization and discrete logarithms. However, Shor’s algorithm, a quantum algorithm, can solve these problems efficiently. Once large-scale quantum computers become available, they could decrypt sensitive information secured under these systems, rendering current public-key cryptography obsolete.

To address this challenge, researchers are rapidly developing post-quantum cryptography (PQC)—encryption algorithms that are believed to be resistant to quantum attacks. The U.S. National Institute of Standards and Technology (NIST) is actively leading efforts to standardize such quantum-resistant algorithms. Examples include lattice-based cryptography, hash-based signatures, and code-based encryption, which are designed to withstand attacks even from quantum computers. These new methods aim to protect data not only today but also in the future, anticipating a world where quantum technology is mainstream.

On the other hand, quantum computing also presents new tools for enhancing cybersecurity. Quantum Key Distribution (QKD) is a secure communication method that uses quantum mechanics to encrypt and transmit keys in such a way that any attempt to eavesdrop would be immediately detectable. QKD enables the creation of unbreakable encryption under ideal conditions, making it a promising technology for ultra-secure communication between government, military, and financial institutions.

However, the integration of quantum computing into cybersecurity is not without challenges. The practical deployment of quantum-safe protocols requires extensive changes to existing infrastructure. Moreover, current quantum computers are still in their early stages—known as Noisy Intermediate-Scale Quantum (NISQ) devices—which limits their immediate threat potential. Nonetheless, the concept of "harvest now, decrypt later" is a real concern, where adversaries collect encrypted data today with the intention of decrypting it using quantum systems in the future.

In conclusion, quantum computing is reshaping the landscape of cybersecurity, offering both disruptive threats and novel defenses. Preparing for this future involves a dual strategy: developing and deploying quantum-resistant cryptographic standards while exploring secure quantum-enhanced technologies like QKD. Governments, organizations, and researchers must collaborate to ensure a smooth and secure transition into the quantum era, safeguarding data in a world where computing power is no longer limited by classical constraints.

# Quantum Vacuum Interaction Drive (QVID): A Reactionless Propulsion System Using Current Technology

**Abstract**

Traditional spacecraft propulsion relies on Newton's third law, requiring reaction mass that fundamentally limits mission capability and interstellar travel prospects. This paper presents the Quantum Vacuum Interaction Drive (QVID), a reactionless propulsion concept that generates thrust by interacting with quantum vacuum fluctuations through precisely controlled electromagnetic fields. Unlike theoretical warp drive concepts requiring exotic matter, QVID uses only current technology: high-temperature superconductors, precision electromagnets, and advanced power electronics. Our analysis demonstrates that a 10-meter diameter prototype could generate measurable thrust (10⁻⁶ to 10⁻³ N) using 1-10 MW of power, providing definitive experimental validation of the concept. If successful, this technology could enable rapid interplanetary travel and eventual interstellar missions without the tyranny of the rocket equation.

**Keywords:** reactionless propulsion, quantum vacuum, Casimir effect, superconductors, space propulsion

## 1. Introduction: Beyond the Rocket Equation

The fundamental limitation of rocket propulsion was eloquently expressed by Konstantin Tsiolkovsky in 1903: spacecraft velocity depends logarithmically on the mass ratio between fueled and empty vehicle. This "tyranny of the rocket equation" means that achieving high velocities requires exponentially increasing fuel masses, making interstellar travel essentially impossible with chemical or even fusion propulsion [1].

Every rocket-based mission faces the same mathematical reality:

```

ΔV = v_exhaust × ln(m_initial/m_final)

```

For Mars missions, 90-95% of launch mass must be fuel. For interstellar missions reaching 10% light speed, the fuel requirements become astronomical—literally requiring more mass than exists in the observable universe.

Reactionless propulsion offers the only practical path to interstellar travel. However, most concepts require exotic physics: negative energy density, spacetime manipulation, or violations of known physical laws. This paper presents a different approach: using well-understood quantum field theory to interact with the quantum vacuum through electromagnetic fields generated by current technology.

### 1.1 Theoretical Foundation: Quantum Vacuum as Reaction Medium

The quantum vacuum is not empty space but a dynamic medium filled with virtual particle pairs constantly appearing and annihilating [2]. These fluctuations are not merely theoretical—they produce measurable effects:

- **Casimir Effect**: Attractive force between conducting plates due to modified vacuum fluctuations

- **Lamb Shift**: Energy level modifications in hydrogen atoms caused by vacuum interactions

- **Spontaneous Emission**: Atomic transitions enhanced by vacuum field fluctuations

- **Hawking Radiation**: Black hole evaporation through vacuum fluctuation asymmetries

If spacecraft can create asymmetric interactions with these vacuum fluctuations, the result would be net momentum transfer—thrust without reaction mass.

### 1.2 Current Technology Readiness

Unlike speculative propulsion concepts, QVID requires only technologies that exist today:

**High-Temperature Superconductors:**

- REBCO (Rare Earth Barium Copper Oxide) tapes: 20+ Tesla field capability

- Operating temperature: 20-77K (achievable with mechanical cooling)

- Current density: 1000+ A/mm² in space-relevant magnetic fields

**Precision Power Electronics:**

- IGBTs and SiC MOSFETs: MHz-frequency switching with MW power handling

- Demonstrated in particle accelerators and fusion research facilities

- Efficiency >95% for high-frequency, high-power applications

**Cryogenic Systems:**

- Stirling and pulse-tube coolers: Multi-kW cooling capacity at 20-77K

- Space-qualified systems operational on current missions

- Passive radiative cooling viable for deep space operations

**Control Systems:**

- Real-time magnetic field control: Demonstrated in fusion plasma confinement

- Sub-microsecond response times with Tesla-level field precision

- Adaptive algorithms for complex multi-field optimization

## 2. Physical Principles and Theoretical Analysis

### 2.1 Quantum Vacuum Field Dynamics

The quantum vacuum can be described as a collection of harmonic oscillators representing electromagnetic field modes. Each mode has zero-point energy:

```

E_0 = ½ℏω

```

The total vacuum energy density is formally infinite, but differences in vacuum energy between regions are finite and observable [3].

**Casimir Pressure Between Plates:**

For parallel conducting plates separated by distance d:

```

P_Casimir = -π²ℏc/(240d⁴)

```

This demonstrates that electromagnetic boundary conditions can modify vacuum energy density, creating measurable forces.

### 2.2 Dynamic Casimir Effect and Momentum Transfer

Static Casimir forces are conservative—they cannot provide net propulsion. However, dynamic modifications of electromagnetic boundary conditions can break time-reversal symmetry and enable momentum transfer from the quantum vacuum [4].

**Key Physical Mechanism:**

1. Rapidly oscillating electromagnetic fields modify local vacuum fluctuation patterns

2. Asymmetric field configurations create preferential virtual photon emission directions

3. Net momentum transfer occurs due to broken spatial symmetry in vacuum interactions

4. Thrust is generated without ejecting reaction mass

**Theoretical Thrust Estimation:**

For electromagnetic fields oscillating at frequency ω with amplitude B₀:

```

F_thrust ≈ (ε₀B₀²/μ₀) × (ω/c) × A_effective × η_coupling

```

Where:

- ε₀, μ₀: Vacuum permittivity and permeability

- A_effective: Effective interaction area

- η_coupling: Coupling efficiency (0.01-0.1 estimated)

### 2.3 Superconducting Coil Configuration for Vacuum Interaction

The QVID system uses superconducting coils arranged in a specific geometry to create asymmetric vacuum field interactions.

**Primary Configuration: Helical Resonator Array**

- Multiple helical coils arranged in toroidal geometry

- Counter-rotating magnetic fields creating net angular momentum in vacuum fluctuations

- Resonant frequency optimization for maximum vacuum coupling

- Active phase control for thrust vectoring

**Mathematical Field Description:**

The magnetic field configuration follows:

```

B⃗(r,t) = B₀[cos(ωt + φ₁)ê_z + sin(ωt + φ₂)ê_φ] × f(r)

```

Where f(r) describes spatial field distribution and φ₁, φ₂ control phase relationships.

**Resonance Optimization:**

Maximum vacuum coupling occurs when electromagnetic field oscillations match characteristic frequencies of local vacuum mode structure:

```

ω_optimal ≈ c/λ_system

```

For 10-meter scale systems: ω_optimal ≈ 3×10⁷ rad/s (5 MHz)

ACT Math Practice Tips for Mastering Every Section

The ACT Math section can feel like a high-pressure sprint: 60 questions in 60 minutes, covering everything from basic arithmetic to trigonometry. Whether you’re a math whiz or someone who breaks into a sweat at the sight of equations, strategic ACT Math practice is the key to boosting your confidence and score. This guide will walk you through the test’s structure, the topics you need to master, actionable strategies, and the best resources to help you prepare—without any fluff or sales pitches. Let’s dive in!

Understanding the ACT Math Section: What You’re Up Against

The ACT Math test is a 60-minute, 60-question marathon designed to assess skills you’ve learned up to the start of 12th grade. It’s multiple-choice, calculators are allowed (with some restrictions), and there’s no penalty for guessing—so always answer every question! Here’s what you need to know about the content and structure:

Content Breakdown

The test focuses on six core areas, weighted by approximate percentage:

Pre-Algebra (20–25%) involves fractions, ratios, percentages, and basic number operations. These topics form the foundation of many questions on the test.

Elementary Algebra (15–20%) covers solving linear equations, inequalities, and simplifying expressions. A strong grasp of these concepts is essential for handling more complex algebraic problems.

Intermediate Algebra (15–20%): includes quadratic equations, functions, and systems of equations. This section tests your ability to solve more advanced equations and interpret complex algebraic relationships.

Coordinate Geometry (15–20%) focuses on graphing lines, circles, and understanding slopes and distance formulas. Mastering these concepts is key to solving geometry problems on the coordinate plane.

Plane Geometry (20–25%) involves the properties of shapes, angles, and geometric proofs. Understanding these concepts is essential for geometry-based questions on the test.

Trigonometry (5–10%) involves right triangles, sine/cosine/tangent functions, and basic trigonometric identities. While this section is smaller, it's still important to understand these concepts well.

You’ll also receive three subscores (Pre-Algebra/Elementary Algebra, Intermediate Algebra/Coordinate Geometry, and Plane Geometry/Trigonometry), which help pinpoint strengths and weaknesses.

Key Logistics

No formula sheet: You won’t get a formula sheet, so make sure to memorize essential formulas like the quadratic formula and the area of a circle before the test.

Calculator policy: Most graphing calculators are allowed, but avoid models with a computer algebra system (CAS). Double-check your calculator ahead of time to ensure it meets ACT guidelines.

Pacing: Aim for one minute per question. Prioritize easier problems first, quickly solving them and returning to more difficult ones later to maximize your score.

Key Topics to Focus On During ACT Math Practice

While the ACT covers a broad range of math concepts, certain topics appear frequently. Here’s what to prioritize:

Pre-Algebra & Elementary Algebra

These foundational topics make up nearly 40% of the test. Focus on:

Word problems involving ratios, percentages, and proportions, which are often framed in real-life scenarios.

Solving linear equations and inequalities, with an emphasis on real-world contexts such as determining the cost of items after tax or finding the time required for a journey.

Basic statistics, including mean, median, mode, and probability, and their applications in everyday situations like analyzing data or predicting outcomes.

Intermediate Algebra & Coordinate Geometry

These sections test your ability to solve more complex equations and interpret graphs:

Quadratic equations especially through factoring, completing the square, and applying the quadratic formula, which are essential for understanding more advanced mathematical concepts.

Functions including linear, polynomial, and logarithmic types, which are key in analyzing real-world trends such as growth patterns, financial models, and scientific data.

Graphing lines and circles, along with analyzing slopes, midpoints, and distances between points, which will test your spatial reasoning and understanding of coordinate geometry.

Plane Geometry & Trigonometry

Though trigonometry is the smallest category, it’s often the trickiest for students:

Area and volume calculations for two-dimensional and three-dimensional shapes like triangles, circles, spheres, and pyramids.

Understanding triangle properties such as the Pythagorean theorem, and the principles of similar and congruent triangles.

Basic trigonometric ratios such as sine, cosine, and tangent (SOH-CAH-TOA) along with unit circle concepts.

Top Strategies to Maximize Your Score

Knowing the content isn’t enough—you need smart test-taking tactics. Here’s how to practice effectively:

Simulate Real Test Conditions

Taking timed practice tests weekly will help build your stamina and pacing for the ACT. Using official ACT tests provides the most accurate experience and prepares you for the real exam. After each test, review your mistakes thoroughly. Reflect on whether the error was due to a calculation mistake, a misread question, or a gap in your knowledge.

Master Time-Saving Tricks

For algebra, try plugging in answer choices instead of solving from scratch. Eliminate obviously wrong answers to improve guessing odds. Use your calculator only for complex calculations, like trigonometry.

Avoid Common Pitfalls

It’s important not to over-rely on your calculator, as some problems can be solved faster mentally or with scratch work. Always double-check the units and wording of questions, especially if they involve measurements. For example, a question asking for the "radius" but giving the "diameter" is a common trap to watch out for.

The Best Resources for ACT Math Practice

You don’t need to spend a fortune to prepare well. Here are trusted free and paid tools:

Free Resources

Official ACT Practice Tests are the best for realistic questions and can be downloaded from the ACT website. Khan Academy offers free video tutorials on algebra, geometry, and trigonometry. Varsity Tutors provides diagnostic tests and concept-specific drills.

Paid Resources

The Official ACT Prep Guide includes six full-length practice tests with detailed explanations. PrepScholar offers an online course that adapts to your strengths and weaknesses. Barron’s ACT Math Workbook focuses on problem-solving strategies and high-yield topics.

Pro Tip: Build a Study Schedule

Start early with 2–3 months of consistent practice. Mix content review with practice tests, spending about 30% on learning concepts and 70% on applying them. Track progress weekly to note improvements in speed and accuracy.

Final Thoughts: Turning Practice Into Progress

The ACT Math section isn’t about being a human calculator—it’s about strategy, pacing, and knowing where to focus your energy. By targeting high-impact topics, practicing under timed conditions, and using mistakes as learning tools, you’ll build the skills to tackle even the toughest questions. Remember, consistency is key: Even 20–30 minutes of daily practice can lead to significant improvements. Now grab that calculator, hit the books, and get ready to crush this test!

¶ … Clinical vs. Academic Study in Medicine One of the most fascinating subjects of today is undoubtedly medicine, and all the science, practice, or theory that comes with it. It is vital for new doctors to become accustomed quickly with surroundings in a hospital, for example, and to know how to treat patients or diagnose them in a matter of minutes; but it is also vital for them to have a base of academic knowledge on which to rely at all times. These two factors, then, can help shape an individual as a physician and render him or her capable or incapable of being successful in the field. This paper will thus speak about why both clinical and academic studies are necessary for a successful medical career, as well as what balance can be struck between the two to ensure optimal learning. The best illustration of the long-going debate on practice vs. theory is in an Oliver Wendell Holmes quote that states: "The most essential part of a student's instruction is obtained not in the lecture -- room, but at the bedside." . Available: http://www.doctorspage.net/quotes.asp. Accessed: 18 October 2011. Updated 2005.] According to the author above, clinical study is the best way for a young physician to learn about the profession. The 'bedside' in this quote thus refers to clinical study and 'lecture room' refers to academic study. Though for Holmes, practice is above theory, practice should not be all a student undergoes -- as theoretical study cannot be neglected. Yet there are some elements that can lead one to concur with Holmes, and state that indeed clinical study is the most essential part of medical education. For example, in a study, on the "scale of consciousness," the authors claim that "academic medicine' calibrates at exactly 440, whereas clinical and holistic medicine calibrate at level 445. Thus, by external verification, clinical medicine (such as nutritional/orthomolecular medicine) arises from a higher level of consciousness (the scale is logarithmic; therefore five points higher are quite significant)." According to this study, due to the fact that there is a "higher" consciousness involved in practice, i.e. that the person is wholly there observing with all five senses, this mode is superior to academic study. Yet one cannot help but wonder if, without academic study, one could learn just as well. . Available: http://orthomolecular.org/library/jom/2006/pdf/2006-v21n04-p197.pdf. Accessed: 18 October 2011. Updated 2006. ] The importance, or balance, of clinical as well as academic study can also be illustrated in course structures at major universities. For instance, if clinical study were to be above academics, or vice versa, no university would try so hard to strike a balance between the two. At the University of Oxford, a student thus undergoes two phases of study. These are the pre-clinical (academic) and the clinical. According to the program brochure, this is meant to give students a balance between theory and practice. Thus, the pre-clinical part of study includes theoretical instruction in such areas as the organization of the body, physiology, biochemistry, medical genetics, systems of the body, the nervous system, etc., and it takes five terms. The clinical part takes three years, and focuses on "honing clinical skills," as well as improving specialist clinical areas and consolidating skills in preparation for practice. The latter field each have, in turn further subsets. . Available: http://www.medsci.ox.ac.uk/study/medicine/pre-clinical/structure. Accessed: 18 October 2011. Updated October 2011. ] . Available: http://www.medsci.ox.ac.uk/study/medicine/pre-clinical/structure. Accessed: 18 October 2011. Updated October 2011. ] Balance, as seen above, is quite important, and, as seen above, each type of study structure has its advantages. One is therefore left to conclude that medicine should always consider a balanced approach between clinical and academic study, for without one, the other will not work well and a doctor will neither work at his or her full potential, nor be successful in his or her profession.

R - Binary outcomes

3/17/25

Some interesting binary variables i've been thinking about in relation to my life at CWRU.

When seeing someone on the quad passing by in opposite directions, how close are our perceived relationships with each other?

Do I wave at them as we pass by?

Do I shout their name if they're going along a different path?

Do they respond?

Do we have anything in common to actually talk about?

In relation to parties (especially those advertised through stories on instagram, without actual invites)

Does someone regularly use social media?

Has someone seen my post?

Is it worth inviting someone?

Should I reach out again over text / in person?

Confounding variables:

Will they talk about it with their friends?

Do others at the party know them?

Are they the type to come out / have fun if I do convince them to come?

Are they going to require convincing to come?

Will they chip in for food?

Will they eat an normal amount of food?

Do they live nearby?

Are their friends also invited?

Will they ask for plus-ones?

These kinds of variables are all over the place in the world! Trying to make a decision, categorize anything (people especially), trying to plan a future event, etc etc.

If I was to build a model of how likely someone is to come to a party based on these factors - something like how much food they will eat could be modeled as a probit (since it's probably a normal distribution), versus how close they are to the greater community is more likely to be modeled as a logit, because that seems to me closer to a logarithmic distribution of connections in a web of friend groups. It'd be fun to make a model of how likely I am to invite a given person to a party depending on these factors, and by attaching weights to them, being able to rank someone new into the list. You could totally train a neural network on this in order to predict / generate lists of people to invite, and create sort-of tier lists to automatically invite people in order to keep numbers at a party roughly equal no matter what's going on.

Analog pink noise generator

Pink noise is an essential tool in audio testing, widely used for analyzing speaker systems, room acoustics, and crossover networks. Unlike white noise, which has equal energy across all frequencies, pink noise features equal energy per octave, making it ideal for audio response testing. This characteristic ensures that pink noise offers a flat frequency response when analyzed on a logarithmic scale, providing a more accurate representation of audio systems.

We developed a this pink noise generator to meet various audio testing requirements. This device combines simplicity and performance, featuring a minimal component count for ease of assembly without compromising accuracy and usability. This pink noise generator design uses a reverse-biased emitter-base junction of a 2SC945 transistor as the noise source. In this configuration, the transistor behaves like a noisy zener diode, producing a broad spectrum of white noise.

In this design the NJM4558 op-amp is used to amplify and buffer the generated noise, ensuring high input impedance, stability, and consistent performance. At this stage above generated white noise is converted into pink noise using a 3dB/octave filter, which ensures equal energy distribution per octave over the audio frequency range.

The unit operates on a single-rail DC power source, compatible with 12V to 18V inputs. At our testing we found that this kit with 2SC945 from Matsushita electric starts to generate output at 8.4V and above. As we noticed this behavior is changing from vendor to vendor. For example some 2SC945's (It's manufacturer is difficult to identify) produces output at 9.1V. By considering most of the datasheets we decided 12V as the safest voltage which guaranteed the output.

To evaluate the performance of the pink noise generator, we paired it with the Simtelic KT0001 (LM386 power amplifier) module. This setup ensured that the output noise was sufficiently amplified for practical testing scenarios. This kind of setup is useful to identifying anomalies in speakers and crossover networks, measuring and optimizing room responses for audio clarity, and for microphone calibrations. When connecting this kit to an amplifier, pre-amplifier, or other analog audio equipment, always use shielded audio cables (UL1185 or equivalent) with the shortest possible length. Long, unshielded cables may introduce hum, oscillations, and distortion in the output.

The PCB for this module was fabricated by PCBWay, who generously sponsored this project. PCBWay offers high-quality PCB manufacturing and assembling services. Also, they offer CNC and 3D printing services. The pink noise generator PCB is available to order from PCBWay. Check out the PCBWay website for its manufacturing capabilities and pricing.

This kit is also available for purchase from Simtelic as a DIY kit. It is designed with through-hole components and can be assembled and tested without the need for specialized electronic assembly tools or instruments. For more details, refer to the kit's user manual provided on the Simtelic website.

Incorporating Memory and Stochastic Volatility into Geometric Brownian Motion Model

Incorporating Memory and Stochastic Volatility into Geometric Brownian Motion Model Geometric Brownian Motion (GBM) is a widely used mathematical model for simulating the random behavior of asset prices in financial markets. It assumes that the price of an asset follows a continuous-time stochastic process, where the logarithmic returns are normally distributed. GBM is foundational in option pricing models like Black-Scholes-Merton. Despite its widespread use, the GBM model has limitations. Reference [1] addresses these limitations by incorporating long memory (long-range dependence) and stochastic volatility into the GBM framework. Three models were studied: Model 1, the classic GBM, which excludes both memory and stochastic volatility, Model 2, the fractional geometric Brownian motion (FGBM), which includes memory but ignores stochastic volatility, and Model 3 incorporates both memory and stochastic volatility. The study empirically analyzes these models by forecasting the Euro exchange rate against three currencies: Saudi Riyal (SAR), US Dollar (USD), and Australian Dollar (AUD). The authors pointed out, Exchange rates play a crucial role in the financial trade of any country, especially in international trade. Therefore, understanding the future direction of exchange rates is a priority for stakeholders. To achieve this goal, many researchers in the literature have proposed several models. In this study, the researchers utilized three GBM-based models to predict the exchange rates of three currency pairs: EUR/USD, EUR/SAR, and EUR/AUD. The first model followed the traditional GBM approach without considering memory or assuming stochastic volatility. The second model, known as GFBM, incorporated memory but ignored the assumption of stochastic volatility. Finally, the third model, also a type of GFBM, took both memory and stochastic volatility into account. After performing predictions with all three models, it was observed that the third model demonstrated superior performance, as evidenced by its lowest Mean Squared Error (MSE). This result indicates that incorporating memory and assuming stochastic volatility in GBM positively impacts its effectiveness as a tool for predicting exchange rate prices. Therefore, given the high accuracy shown by model 3, it can confidently be used for forecasting future exchange rates. In short, the findings suggest that incorporating long-range memory and stochastic volatility significantly enhances the model's predictive power. Let us know what you think in the comments below or in the discussion forum.

I'm about to make a lot of rough assumptions to get to the point of my notes for myself lol

So this ALG article has the equation for estimating how much comprehensible input it will take to acquire % of a language understanding. And in this case, comprehensible input just means experiences/happenings (or witnessing them) where you understand the main idea of what's going on. Since it's ALG, they assume NO word lookups and no conscious guessing the meanings of stuff, so my estimate is going to be really fucking weird compared to theirs when applied to me as... I did a lot of word lookups, and guessed a lot.

The BASIC LANGUAGE ACQUISITION EQUATION: y = 1-e-kx

where y is how much language they know (1 = native).

x is how many hours they have understood.

k is the acquisition constant: .0018

e is the natural logarithm base:  2.718

The article does go on to say that if you did 100 hours engaged with the language, if you only understood say 50% of what's going on then you would put 50 hours into the equation. Because you want to aim to only count hours worth of time you UNDERSTOOD meaning.

What I find cool about this equation, is 1000 hours is 83% understanding, 1400 hours is 91% understanding (both great goals). 1500 hours is how long Dreaming Spanish estimates learning Spanish will take as an English speaker (less for a Romance language speaker), and it appears this equation primarily made for learning Thai as an English speaker, ALSO estimates good progress by around 1500 hours. At 2200 hours, this equation estimates 98% understanding which is a great goal for doing most anything in a language (and is fairly close to some estimates I've seen of how long to give ALG for languages not similar to your own). Now... since not all hours of study you will understand 100% of what's going on, you're going to want to either double those hours (assuming you understand 50%) or at least assume some of those hours of study only count for 75% understanding. So considering those factors, actual hours of study you understand OR not, is going to be closer to somewhere between 2200-4400 hours to get good enough to understand 98% of the language a native can understand. Now this matches up quite well with people's experiences they've shared, and with the experience of BOOK/classroom/explicit learners, as well as ALG learners. Although... I would guess an ALG method minded person would argue that the explicit learner needs more hours, in general, of comprehensible input, to hit certain milestones. But at a certain point, explicit learners are doing most study hours as just that, comprehensible material they understand the main idea of, like me watching shows/reading/listening to audiobooks now in chinese with word lookups only 5% of the time.

So anyway, for fun, I wanted to see where this equation thinks I'd be so far. So with Chinese, I studied what, 4 years? I'm going to try and underestimate. But I feel like I'm coming up on 5 years, whatever. Let's say 4 years, let's say 2 hours per day on average the first 2 years - so 1460 hours the first 2 years. Let's say 30 minutes on average the next 2 years, because I did take like 3-6 months off of studying to focus only on Japanese, so 365 hours for those 2 years. So a total of 1825 hours. Damn. That's more than I expected! Okay, now lets cut out hours spent not understanding without lots of word lookups (the whole first year of 730 hours. 1825-730=1095. Okay, now let's assume out of the 1095 hours, only 75% of it counts for 'comprehended input' if I don't count times I looked up words often, or I couldn't grasp the main idea. The truth could be closer to 50% or closer to 95% depending on if the times I looked up words occasionally hurt my progress or helped it. 1095*.75=821.25 hours. If we do the conservative estimate of only counting 50% then it's 547.5 hours. Let's see where the equation places me:

1-2.718^(-.0018*547.5)= 63% (rounded)

1-2.718^(-.0018*821.25)= 77% (rounded)

That's pretty good!

Now lets see how that matches up to Thai learners, they're expected to need around 1000 hours for 83% so I will probably hit my next milestone in 200-400 hours of chinese material I understand the main idea of. They're also expected to start speaking around 800-1000 hours, just simple stuff, so I can probably start speaking now or in 200 hours and 'not expect' much damage. (Although I may already have lots of 'damage' ALG thinks concious guessing/translations cause, so I might already be a lost cause there).

My personal guess is that I'll probably need 534 hours, if we assume the stuff I'm engaging with is only 75% comprehensible. Or 600 hours, if we round it up and give me more cushion room for not understanding some stuff.

And for fun for me: if I count my FULL hours studied 1825 hours, I am in Level 7, if I count only comprehended it's 1095 or Level 6 Dreaming Spanish Roadmap's levels wise (which is where I think I feel I am based on skills I can do - around Level 6, Skills include most native media, reading, conversation recommended). If I don't count any of my explicit study, I'm at 821.25 hours or Level 5 (easier native media, reading optional, conversation optional).

Hearts of the Multiverse-Chapter Seven: The Bidding

A/N: If you’re here from Tiktok, welcome! Yes, I saw it haha. I actually thought it was funny, and I thank the OP for all the reads it got me. I understand that this crossover is a bit…ambitious to say the least. However, I’m just paying homage to some stuff I love. I really love Sailor Moon S. It is my favorite arc of the series. If this goes successfully, I might do Super S and Stars multiverse style haha. I did change the rating to mature because I wrote some innuendos for Angel Dust and Astarion. However, I am not showing anything explicit. I don’t like writing that stuff, to be honest. No hate to people who do. It’s just not my thing. I’m more about fluff and adventure. So, without further ado, I hope you like this chapter. Be sure to let me know what you think in the comments below!

              And so, Miles and others joined Rei’s study group. It started as pure interest for Sokka. He wanted to see how stuff differed from the Southern Water Tribe (The Four Nations, really). Katara thought this was a great idea and became interested herself, reluctantly bringing Zuko into the group. Miles noticed that some *cough* Minako, Usagi, and Makoto *cough* would struggle with a lot of math, science, English, history, and anything that wasn’t the humanities. Considering he was a top student, he helped them. Giorno joined because he was great at math, especially anything statistics based. Arven was behind in his own studies, so he joined after Nemona insisted they join. Luz was on par with Giorno. Hunter was also a pretty fast learner; truth be told, Miles thought they joined because they had fun hanging out with everyone. Josuke joined because he also needed to study—like a lot. Lillie helped when she could, although most times, she was talking to Gideon. Pav and Kakyoin would occasionally come over and help, since there were a lot of people who needed it. Adora trained instead, and Starfire took an interest if Robin were in the study session. Anne actually did study with them, something about needing to master MLA skills (to which Luz and Miles gladly helped). Sometimes Kaiba, Robin, and Connie would stop by to report anything they found, or study. Connie and Robin seemed impressed by Ami. Connie wanted to keep up with Ami somehow even after everything had returned to normal. Though Miles would tell her, that’s not necessarily a good idea. Even Kaiba seemed impressed by Ami. And, admittedly, Miles was, too. She solved the hardest mathematical equations he’d seen.

              “Miles, is number eight right?” Mako asked, holding up her paper in front of him.

              He’d been popular around the study table. He did know what he was talking about, but it was a much-needed ego boost. Funny thing was, Mako asked him a lot more than the others, despite Giorno probably being the best at math.

              He glanced over the problem and gave her a smile. “Yeah! You got it, Mako!”

              “Haha!” Mako cheered, pumping her fists in the air. “Thanks Miles! I would’ve never understood these dumb logarithmic equations without you.”

              “You would’ve gotten it,” Miles assured her. “You just needed someone to show you a play-by-play.”

              “I suppose so,” Mako said with a small giggle.

              “WHAT DO YOU MEAN IT’S NOT NEGATIVE SEVEN?” Josuke and Usagi asked in unison.

              “You two really shouldn’t copy each other’s answers to try and get out of work,” Rei said, sipping a cup of tea. “You’re both really bad at math. Why didn’t you ask Ami, Giorno, or Miles for help?”

              “Because then the math will have won, Rei,” Josuke insisted.

              Usagi laughed. “Yeah! He’s right!”

              She slammed her homework down on the table and pointed to the problem in question, “In the name of the moon, I’ll punish you!”

              It was quiet for a minute before Josuke gave her a pity laugh. She hung her head. “Oh, come on, that was funny.”

              “We’re not here to make jokes,” Zuko said sternly. “We’re here to study.”

              “You’re just mad you had to join,” Katara teased.

              “I agree,” Giorno spoke up, albeit a bit hesitantly. “Zuko is right. We’re supposed to be helping you study.”

              Zuko, caught off guard a bit, seemed suspicious, and then a little guilty. Guy was hard to read. Giorno didn’t react, even if he noticed.

              He turned to Miles. “Miles, Minako is struggling with this bit of theory, I don’t have the answer, do you think you can help her?”

              “Sure,” Miles said, taking a glance at the textbook.

              It was on dark matter. It seemed so long ago that he was studying dark matter in his dorm room, trying to find a way to get back to the other universes. Now that they were in one messy conglomerate, he dreaded who would come by the shrine next. He was surprised Gwen hadn’t. Apparently, both Pav and Kaiba had stuck to their words of not letting her know where they were. He didn’t want to see her—not right now.

              “It’s matter that doesn’t absorb, reflect, or admit light,” Miles explained. “People theorized it could be used to cross dimensions—universes even.”

              “Then why aren’t we using it?” Sokka asked.

              “It’s all speculative theory, some people say,” Miles said. “Though, I know it’s real.”

              “How?” Zuko asked.

              “Used it before…by accident,” Miles said with a laugh. “And so have people I fought. They’re the scary ones. Villains who can travel through dimensions should be taken seriously.”

              Voice of experience.

              Rei frowned. “You don’t think the heart snatchers could be from a different universe, do you?”

              “It’s possible,” Miles said honestly. “I’d worry about those two senshi who seem to be out for their own ‘mission,’ too. They’re probably more dangerous than your villains of the week. Maybe THEY’RE from another dimension.”

              Usagi shook her head. “I don’t think so. We’re all senshi. We have to be similar somehow. They always give the crystals back.”

              “They almost gave Unazuki’s back too late,” Sokka pointed out. “She could’ve died.”

              “Maybe try talking to them?” Katara suggested. “I think both of you have a point. They fight the daimon just like we do. You could try to convince them to join up. After all, Usagi, you said the senshi are supposed to be a team. So, there could be other reasons why they’re hesitant to help our team.”

              “You need to be careful,” Zuko murmured. “People who are driven by their own goals and motivations, no matter how flawed, can be too determined to their own point of view. It might be hard to get them to talk to you—or compromise.”

              “Good advice,” Giorno said.

              Again, another stare. At this, even Giorno seemed confused.

              “Hey, excuse us for a second,” Miles said, pulling Giorno into a disconnected room. Once he was sure no one was watching, he asked, “Dude, what are you doing?”

              “…Trying to be friendly.”

              “Dude, that is not friendly. That’s suspicious! Muy sospechoso!”

              “It’s not as easy as it looks. The people I’ve dealt with did all the interpersonal stuff better,” Giorno said.

              “It’s easy,” Miles said. “You’ve just gotta relax, you know? Just be natural. Talk like you’re talking to your friends.”

              “Those aren’t a sure thing where I come from, Miles,” Giorno snapped back. He sighed. “Look, I appreciate the advice, it’s simply harder to know who’s your friend for the sake of business and who is eventually going to stab you in the back.”

              Miles was quiet for a minute. Of course, he knew what that was like. The insinuation of doubt was almost insulting.

              “I know you’ve said your friends betrayed you,” Giorno said. “But at least you have a good family. You’re fighting hard for your dad. It’s admirable. I never had any of that. Not that I’m whining, but you have to understand where I’m coming from Miles.”

              “I—,” Miles began. He cut himself off. He had a feeling this was the first time Giorno had opened up to anyone, maybe ever. “No. You’re right. I wouldn’t know. I’m sorry.”

              He kind of chuckled. “The first time I talked to Gwen, I ended up ripping her hair out.”

              Giorno blinked. “What?”

              “I was taking my uncle’s advice. He was super good with girls, and he taught me the shoulder-technique.”

              “Do I dare ask?”

              Miles reached his arm out and loosely touched Giorno’s shoulder. He raised an eyebrow and said, “Hey.”

              They were quiet for a minute before they both started laughing. Miles was sure it was the first time he’d ever seen Giorno laugh in the month they’d been here.

               “Did that actually work for him?” Giorno asked.

              “He swore by it,” Miles said.

              “I guess it would work better on someone who was actually interested in that kind of stuff.”

              “No girlfriend back home, huh?”

              “Not interested in it. Relationships would get in the way of my actual interests: reform. There’s too much corruption in Italy. A lot of things I’m still working on. Also, I’ve never been too keen on the idea of a relationship. It just never struck me as something I wanted.”

              “So, you’re ace. That’s cool.”

              It was quiet for a minute before Usagi called out, “Gio! Can you help me with this probability question?”

              Giorno smirked. “Future queen of the moon. Whatever that means.”

              “If you figure it out, let me know.”

              …

              This place was much more grandiose than most taverns he’d stayed in; the cobwebs were a nice touch. Astarion never knew demons to be incredibly hospitable creatures, but the lovely owner and proprietor of this place was kind and generous—her girlfriend—a bit more frightening. She reminded him of Lae’zel. Unfortunately, he also met someone who painfully reminded him of himself. And he could only trust people like himself so much.

              Fortunately, people like himself made for great conversation.

              “So, a vampire…I bet you’ve lived a while,” Angel mused. “Sleep around a lot?”

              “Darling, I lost count over a hundred years ago.”

              “Any of ‘em any good?”

              Astarion scoffed. “A seldom few.”

              He turned a coquettish smile to Angel. “And you?”

              “I do this shit for a living,” Angel bragged. “Though, I’m always better than the other guy.”

              “You must have a contract with someone, then,” Astarion said. “I’m sure neither of us believes in bodily charity.”

              Angel shifted in his high-heeled boots and chuckled nervously. “Heh. Yeah. That’s a good way of putting it.”

              Astarion had been at the hotel for a week now. He’d joined when some wayward priest and another vampire had found him, starved, and hiding from the sun. He wasn’t sure how they had gotten here, but he knew the blonde adonis and his loyal disciple were up to something. One didn’t live with Cazador as long as he did and not figure out when a plot was brewing. If it didn’t involve encroaching upon his safety, well, Astarion didn’t care. Besides, he’d shown him kindness by taking him to his hotel. Little Miss Demon Sunshine kept him fed.

              Though, one thing he did note is that he and the so-called radio demon did not get along. He sensed an unease, something the blonde had against the demon. Perhaps he was doing some sort of surveillance on him, but as to what purpose, Astarion wasn’t sure. Admittedly, the always-smiling, Radio Demon possessed a charm to disturb and set himself apart from the others. Astarion had talked to him once, and once was enough.

              The white-haired prosecutor mainly kept talking to Miss Sunshine, her angel girlfriend, and the bartender. They seemed to get along the best.

              Right now, Angel and Astarion were keeping a casual eye on the television (or the visual sending stone as he preferred) in the center of the room. Some broad-shouldered, tall, dark, and handsome was speaking: “Anomalies have been growing at an alarming rate. There has been no sign of universal disruption, but we are keeping a continuous eye out for anything or anyone who could prove to be dangerous for public safety and wellbeing.”

              “Manipulation at its finest,” A dark and deep voice mused near them.

              “Gods damned!” Astarion shrieked, shrinking back from the silent eavesdropper. It was the other vampire, Dio. “How did you bloody do that? I’m usually the first to sense if someone is near me, thank-you-very-much!”

              Dio smirked. “Isn’t blasphemy contrary to what is supposed to be practiced here?”

              “He’s got a point,” Angel said with a small laugh. “You done sinned, gorgeous. You should be punished.”

              Astarion flustered and still perturbed, straightened out his clothes. He looked to Dio. “Did you want to speak with us?”

              “Only for a moment,” Dio said. He leaned in. “The cat-man can’t say anything, but I’ve noticed that both of you stay away from Alastor. Why is that?”

              “He’s a dealmaker,” Angel explained. “He makes unfair deals with other sinners to gain an advantage. Weird sinner named Mimzy once said he killed a lot of overlords just to gain their powers. It’s surprising that Hus…well, it’s surprising that anyone who ever makes a deal with him lives to talk about it.”

              “I see,” Dio said, rubbing his chin. He turned to Astarion. “And what do you make of him?”

              “Darling,” Astarion said, taking a swig from a shot-glass of blood. “I’ve met far too many people like Alastor.”

              ‘And like you,’ he wanted to say. But he held his tongue. He didn’t want to exhaust his resources in this strange, new world so quickly.

              “In any case,” Astarion said. “I’ve put my days of making deals with ever-lasting binding terms behind me.”

              “Hey, good for you, man,” Angel said, taking a sip from his own glass. “At least one of us can say that.”

              “Is there any way to get out of a demon’s contract?” Dio asked.

              “Don’t know,” Angel said. “It’s never happened before, I mean, unless the contracted dies, I guess.”

              This wasn’t the answer Dio was looking for. He grimaced and crossed his arms. “I’m sure there is…”

              Angel placed his glass down on the bar and put a hand on Dio’s shoulder, “Well honey, if you find one, let me know.”

              Dio chuckled. “I’m sure I will…and likewise, Anthony.”

              “Wait…how did you?”

              “Alastor has his ways of obtaining information, and I have mine,” Dio said simply.

              Astarion sloshed his glass and without thinking much guessed, “The priest?”

              Dio grinned, more devilishly than any of the inhabitants. “He’s knowledgeable, yes. And he helps when he can, but I’ve seen more to this world…this scheme than most. I refuse to give up. Perhaps if I kill the bastard.”

              “Uh, what?” Angel asked, almost in disbelief. “That’s the stupidest idea I’ve heard. Look, whoever you’re trying to get out of a contract, it’s like I said, it doesn’t stop at the contractor’s death. It stops with whoever’s signed a contract.”         

              “That’s usually how it works,” Astarion nodded. “It’s always stacked in the disadvantage of the poor bastard who’s signed the damn thing.”

              “I suppose you two would know,” Dio said, his face souring. He sat down on one of the more comfortable chairs and held his head in his hand. “To think I’d been brought back to finally fix my mistakes and to have such a huge disadvantage thrown at someone I was supposed to protect.”

              “Did…did someone you care about sign a contract with Alastor?” Angel asked. “Look, you don’t have to tell me, but I get it, you’ll want to help them. I want to help someone get out of his contract, too. Maybe there’s something we’re not seeing, huh?”

              Astarion didn’t respond. Something was off. He’d told his fair share of lies. Perhaps Dio was telling part of the truth, but there was still something lurking. Both he and Alastor, however much in opposition they may be, were the same men. He knew it.

              He knew it because he was much the same. And poor Angel Dust, just like Tav, more concerned for the emotional ramifications than his own safety, seemed genuinely upset. Internally, Astarion groaned. He’d do what Tav did for him; he’d make sure Angel didn’t get hurt or used for some nefarious purpose. He figured he owed that to someone.

              “If you can find a solution, I’ll help you break your contract, Anthony,” Dio said. “Anyone who should help I, Dio, will be greatly rewarded.”

              With that the blonde vampire stood. He gave Astarion an unreadable look. “And I mean anyone. I’ve been told you were freed from your own personal enslavement, correct?”

              Now Astarion shifted in his boots. “It was more of a group effort.”

              “Then you should find your group,” Dio said. “There are forces at work here—ones not to be trusted. I assure you, I will soon gain enough power to put an end to anything that would hurt those of us who never had a chance—those much like ourselves. If only you will help me, I’ll help you. I swear it.”

              “Alright then,” Angel said, surprisingly confident. A feeling Astarion wasn’t currently feeling. “If you’re so trustworthy, you could at least tell us who you’re fighting for. I’m not gonna help some asshole who wants more power for the sake of power.”

              Dio flinched and turned away. “It’s my son. He’s made a terrible error. I must help him.”

              “For real?” Angel asked. “How old is he?”

              “Only fifteen.”

              “Only fifteen?” Angel repeated. “Jesus, I knew Alastor was bad, but not making deals with kids bad.”

              “We shouldn’t talk about that too much here. The prosecutor has agreed to help find any loopholes. If we work together, there is a better world for all of us: no contracts, the sun on our faces, redemption. It’s within reach!”

              ‘Of course there is, Cazador,’ Astarion’s mind screamed.

              However, Angel looked, in that moment, hopeful. So hopeful that Astarion decided he would keep quiet.

              “I’ll do what I can,” Angel whispered. “But you’re right. Maybe we should talk about this somewhere else.”

              He grinned his voice dripping with suggestion, “Perhaps somewhere secluded. You can join, Astarion.”

              “I’m flattered, but I’ve decided to not do that for now. I have the choice, now,” Astarion said. “Still, I suppose I’ll dig around. I don’t exactly trust Alastor, either.”

              Not that he trusted Dio, but if Alastor were making deals like that, with children, no less, well, that was definitely Cazador behavior.

              “And I want that choice, too,” Angel murmured.

              Dio smiled, almost triumphantly. “Then we’ll meet elsewhere. I’ll give you the location later, as a precaution.”

              He sauntered off. Angel was clearly puzzled. At least Astarion wouldn’t fall for anymore tricks.

              Or he was almost sure he would not.

              …

              They’d split up. Bruno went with Abbachio, N (after promising to keep her safe) went with Maya, and he was with Edgeworth today. They’d been at this for a few weeks now. And there was no blooming friendship between Kaiba’s association and their own. Edgeworth frowned more than usual, which was an amazing feat to surpass. The two had gone to meet someone on a hiking trail. It was a woman, who worked with a doctor, apparently, she and her partner had been tipped off to a possible match of someone who fit Rose’s profile. Gideon had received the call and told Phoenix to go talk to her.

 As they walked the dirt paths in the woods, they noticed some people singing and playing instruments, just happily walking along. Something about two lovers divided by a war.

The one with the shaggiest hair stopped, realizing that he and Edgeworth were on the path. “Oh hey, fancy-dressed nomads.”

“We are most certainly not,” Edgeworth objected. He turned to Phoenix, “Well, perhaps him if we lose this case, but certainly not me.”

“Actually, we’re here to meet with a woman who might know of a man by the name of Rose,” Phoenix explained, cutting a quick glare at Edgeworth.

“Rose, huh?” the man repeated. He scratched his chin and drew out a red, wooden guitar (?). “I know a song about some roses.”

Before Edgeworth or himself could protest, the man started playing and singing a new song:

Rose of red

Rose of blue

Once with dread

Now bloom anew

Wanting more

May get to shore

Or perish on the journey

When a more deadly root

Takes their place

Edgeworth furrowed his eyebrows. “Those last few verses lost their rhyme scheme.”

“Scheme-schmeem,” the man said. “Name’s Chong by the way.”

He gestured to the woman, “My wife, Lily.” He pointed to the other, stockier guy, “And that’s our friend, Moku.”

“Charmed,” Edgeworth said dryly.

“Come on, Edgeworth, I’m sure they worked hard on that song,” Phoenix said with a small grin.

“Yes, well, we have places to be,” Edgeworth said, grabbing his arm.

“Hey,” the woman, Lily called out, as they shuffled away. “Be careful, there’s some bad vibes back that way.”

“That’s why we’re booking it now,” Mako said.

Edgeworth stopped and paused for a moment, almost making Phoenix trip over himself. He stood still for a moment and shook his head, pushing forward. “It’s nonsense, Wright. Pure nonsense from vagabonds who speak absolute gibberish.”

“I don’t know, couldn’t they have been talking about one of those monsters?” Phoenix suggested. “They’ve been popping up more, you know.”

Another pause. “Hmm…perhaps we should consider turning back. Though, if we do, we’re both ruined. It wouldn’t matter if a monster were up ahead or Gideon Graves, himself, really.”

Phoenix was quiet for a minute. Sensing the tension. He grinned and nudged Miles’s shoulder, “You sure there’s a difference between them?”

He saw, for a brief second, Miles crack a smile. Mission accomplished. Then back to a frown. Phoenix didn’t mind. It’s just how Edgeworth worked. Honestly, it was kind of admirable to be so dead set on his goals and sense of doing the job correctly. Preferable to his days as the so-called ‘demon prosecutor.’ Edgeworth’s whole perspective had changed for the better. At least now, they could work together to find the absolute truth.

At least now they could spend time together.

“We should take some caution, going forward,” Miles said, “After all, you have a horrible habit of injuring yourself on these cases. Monster or no, let’s make sure there’s no more hospital bills in your near future.”

The grin was still slightly there.

Phoenix shook his head. “Hah. You wish, Edgeworth.”

Solemn was the best way to describe his next look. “I don’t.”

And then there were times when Edgeworth was completely unpredictable. He walked ahead of Phoenix; what had he said?

The two walked in silence until reaching somewhat of a clearing. On one of three stone benches a pale woman with long, red hair sat, waiting patiently. When she spotted the two, her lips formed a small smile.

“Mr. Wright, Mr. Edgeworth. I’m glad to make your acquaintance.” She got up, and shuffled a bunch of papers, thumbing through them methodically. “I’m sure you know why I’m here.”

              “You are Dr. Knight,” Edgeworth assumed.

              The woman nodded and held out the stack of papers towards them. As Edgeworth hesitantly reached for the papers, the magatama activated. At least ten psyche-locks popped up around the woman. She was lying—lying more than anyone he’d seen so far.

              “Wait,” Phoenix said, pushing Miles away from the woman. “Why are you really here?”

              The woman seemed slightly taken aback. She quickly regained her composure and shoved the papers towards Phoenix. “I suppose you’ll do, too.”

              Not even thinking, Phoenix shoved the papers back, causing them to flutter—

              No. Not flutter. The papers glowed. Glowed and swirled around into a vertex, sticking together to form some sort of humanoid monster. Words moved and floated across its body.

              “Papella only needed one of your DNA signatures to attack,” the woman explained as Phoenix backed away. She turned to the monster. “Take this man’s heart and then Mr. Edgeworth, as well. I can make this into a double success for us! Come back to the lab when you’re finished. I have other places to be. More hearts to check.”

              As she disappeared, someone yanked Phoenix away by the collar of his shirt. “Wright! Move!”

              Having their situation sort of register, Phoenix acquiesced and started running with Edgeworth. However, they weren’t too far when something grabbed Phoenix’s ankle, sending him careening to the path below. The monster chuckled as it put down its foot (which looked and felt like a heavy paper weight) down on his chest. It outstretched its palm toward his chest.

              For its effort, a suitcase was launched at its head and the prosecution threw a right hook. However, it caught Miles’s hand. He winced.

              “Edgeworth!”

              The monster, almost effortlessly, tossed him in the air and sent him colliding into a tree, knocking him out cold.

              “How annoying. He’ll have his turn,” the monster said, glaring at Edgeworth. It turned back to Phoenix, a nefarious grin on its face. “Now it’s your last chapter.”

              “Oi oi!”

              Someone literally swung in, faster than any human he’d ever seen. They kicked the monster in the head so hard, it went face-first into the stone benches. The figure landed just a few inches away from him. He kind of looked like Spider-Man. But he wore a vest and a lot of spikes, even on the back of the mask. He held out a hand to Phoenix.

              “You alright, mate?”

              Phoenix barely nodded. He, at that moment, had to get to Miles. He needed to know he was okay. The monster, having regained its composure, looked from Phoenix to the possible Spider-Man. It leapt into the air, landing directly beside Miles. It grabbed him by his collar, holding him up in the air.

              “Don’t come any closer or pretty boy gets it.”

              “Put him down!” Phoenix yelled.

              “No way! Maybe I’ll kill him first, and then you! I’m sure my boss doesn’t care which way it gets done. So long as it gets done.”

              “Right, and who was that boss again?” the British Spider-Man asked.

              “Like I’d tell you.”

              “Sure you don’t want to?”

              “Hell no! I’ll kill all three of you!”

              A bird tweeted in the distance. Another echoed in another tree. And then the creature’s arms were severed from its body. A blond girl in a cheerleader’s uniform covered by scaled armor held the arm in one hand and a pink sword in the other. Edgeworth was caught by a person who leapt down from one of the lower branches. They had teal hair, glasses, and dressed like they were in some sort of English, medieval society. Another boy with brunette hair, similar armor, and two hooks impaled the creature, tearing two gashes through its side.

              He kept a specific hold on the monster. “Hey, Guzma, you want your Golisopod to help drench this old wad of tissue?”

              From the opposite tree came a voice that chuckled darkly. “Heh. Sure. Golisopod! Water beam!”

              One man with white hair and strange shaped glasses, Hawaiian shirt, t-shirt, shorts, and gold necklace resembling the letter ‘S,’ beside him was a hulking, white monster with huge claws. It spat out a plume of water at the monster, drenching it.

              The monster cried out at the teenage boy tore through it with his claws, ripping it in half. It lost its form and turned into regular papers, as it had been before.

              Phoenix was almost too stunned to speak. However, there were pressing matters at hand. He looked to the teal-haired individual holding Miles. “I-is he okay?”

              This person was checking his pulse and nodded. “Yes. Just seems like he hit his head hard. I don’t sense any serious damage, though.”

              Phoenix was quiet for a minute. “Not that I’m not super grateful, but who are all you people?”

              “I’m Guzma. I’m the big, bad boss who beats you down and beats you down…well…I’m Guzma. Not so much a boss anymore. If I’m gonna fix the system, gotta break those hierarchy roles, right HB?”

              “You learn well young Golisopd,” the British Spider-Man said with slight amusement in his voice. “I’m Spider-Man. Well, one of them, at least.”

              “Name’s Jet,” the kid with the hooks said, sticking a grain of wheat in his mouth.

              “Sasha Waybright,” the girl with the sword said with a bright smile. “Man, these things are waaay too easy to kill.”

              “Don’t jinx it,” the teal-haired person warned. “My name is Raine. Who are you two?”

              “Come off it, Raine,” Spider-Man said. “These two are those famous ace attorneys. All about keeping the current system in place, yeah? Even I’ve heard of ‘em.”

              “The three of us,” Sasha said, gesturing to herself, Spider-Man, and Jet. “Keep up with news way more than these two do.”

              “Hey, I invent the news,” Guzma protested.

              “Look, it doesn’t matter,” Raine said. “We need to get these two to safety. Those monsters have been popping up way more. Let’s get out of the park.”

              Raine began by trying to shoulder Miles alone. Phoenix hopped up and ran over to help them out, ducking under his other shoulder.

              “You two must be close,” Sasha remarked. “He basically dived in front of that monster for you. It’s sappy, really. Cute couple goals, though!”

              “You shouldn’t make assumptions,” Raine said.

              “Oh, don’t worry,” Sasha said, showing off a bi-pride pin on her cape. “I would know.”

              “It’s not like that,” Phoenix said. Even if he felt that way.

              But why had Edgeworth done that? He made fun of Phoenix for being careless and reckless. Hell, he’d thought he’d never live down the Kurrain-shrine-bridge incident. Miles yelled and yelled at him, even when he was still in the hospital. And it wasn’t like Edgeworth to be so hypocritical.

              So why?

              …

              A day like this was rare ever since he’d hopped over to this new universe. Everyone was inside, having fun, and Miles was able to take a break outside, by himself. “United in Grief” played through his headphones, letting him escape, if just for a minute. There were no monsters, no impending doom heading for his family, no Miguel O’Hara, no radio demons, and no need to be Spider-Man.

              And then someone tapped him lightly on the shoulder.

              He looked up to see Makoto holding a piece of cake that smelled and looked delicious. It even had a small candy flower at the end.

              “You were missing out. I thought I’d come find you,” she explained. “I’ve been told my cakes are pretty good by one of the hungriest princesses I’ve ever known.”

              Miles grinned and took the cake. “How many princesses do you know?”

              “Including Starfire and Adora? Three. And Zuko’s a prince, so…”

              “He’s a prince?” Miles asked in disbelief.

              “Yeah. He’s pretty open about it now. I guess you just have to get to know him. He’s got a girlfriend and everything. And Sokka said something about his first girlfriend turning into the moon. Maybe they have a moon princess, too.”

              “Wow. I really don’t know a lot about anyone here,” Miles remarked.

              That creeping guilt over being so reclusive seeped into his consciousness again. Maybe it wouldn’t kill him to make more friends than Giorno. Though, the thought of trusting anyone still seemed stupid.

              “I don’t blame you, you know,” Makoto said out of the blue.

              “What do you mean?” Miles asked, raising an eyebrow.

              “Back at Mr. Iroh’s tea place, you said you’d do anything to save your dad, even if all those other people who told you to sacrifice him for the ‘sake of the greater good’ told you otherwise. I’d give anything to go back in time and save my parents.”

              She stared off into the stars. “Sometimes, at night, I wait for them to come home. But they never do. When I go home, to an empty apartment, sometimes I just feel like crying so bad.”

              Miles felt something tug at his heart. She’d been alone? For how long? Did anyone else know about this? He reached out to put a hand on her shoulder but thought better of it.

              “I’m sorry. That must be really hard to cope with.”

              Mako nodded. “It is. No one should have to go through it.”

              She dabbed at her eyes and pulled him in for a hug. “Which is why I’m going to help you! I’m sure Usagi will, too! You two kind of remind me of each other, doing things your own way. I’ll beat up any other Spider-Man who tries to stop you!”

              He laughed. “Thanks, Mako. If…if there’s any way I can help you, I’ll repay the favor.”

              He meant it. She seemed so genuine. It almost threw him off his guard. Almost.

              “Just…try to make more friends here. Talk to Usagi. I know you two would get along. Her dreams are similar to yours. Don’t be so secluded. We need other people to help us. I think even Giorno is getting the hang of it.”

              A slight breeze coursed through the air. Makoto shivered. Miles took off his big, puffy coat and handed it to her. “Don’t worry. My suit keeps me warm. Let’s head back in.”

              She hesitantly took his coat and nodded. “Thank you, Miles.”

              “Don’t worry about it.”

              Maybe he could make more friends here than just Giorno.

Bitcoin Price Soars: Fed Rate Announcement and High Institutional Demand Drive Bullish Revival

Key Points

Bitcoin’s price indicates a bullish recovery due to Federal Reserve’s rate decision and increased demand from institutional investors.

Institutional investors and nation-states are showing a growing demand for Bitcoin.

Bitcoin’s price has been fluctuating around $58K since July, after establishing a firm support level of approximately $54k. This leading cryptocurrency has been forming a weekly reversal pattern, marked by a potential triple bottom and a rising divergence on the Relative Strength Index (RSI). Additionally, the Bitcoin price in the weekly time frame has rebounded from the rising logarithmic trend, which started in late 2022 following the collapse of FTX and Alameda Research.

However, short-term risks of bearish volatility exist, which could cause the leading cryptocurrency to drop towards the $54k support level again before rebounding towards its all-time high. The recent death cross between the 50 and 200 Moving Averages (MA) in the daily time frame continues to heavily impact the midterm Bitcoin price recovery.

The Increasing Demand for Bitcoin

Despite some short-term holders capitulating, the demand for Bitcoin among institutional investors and nation-states has been gradually increasing. According to on-chain data analysis, Tether, the stablecoins issuer, minted 1 billion USDT in the past 24 hours, indicating rising buying pressure.

The Royal Government of Bhutan has recently disclosed holdings of more than 13k in BTC, valued at over $780 million. This South Asian country joins a growing list of nations accumulating Bitcoin to combat their rising debts. For example, El Salvador’s President Nayib Bukele announced that by 2025, the country will operate without any debt financing plan.

El Salvador has been buying 1 Bitcoin per day in recent months and currently holds 5,875 BTCs, worth more than $331 million. Meanwhile, BlackRock’s IBIT led the US-based spot BTC ETFs with a significant cash inflow on Monday, thus outweighing the cash outflows from Grayscale’s GBTC. The US spot BTC ETFs registered a net cash inflow of about $12.9 million on Monday.

Impact of Economic News

The Federal Reserve is expected to make its first interest rate cut on Wednesday, September 18, after years of waiting for inflation to cool off in the United States. Market sentiments suggest a 69 percent chance that the Federal Reserve will initiate a 50 bps interest rate cut. This move is expected to result in a bullish outlook for Bitcoin’s price, both in the short and long term. Furthermore, the US dollar index is gradually falling as the BRICS nations continue to shift from American bonds to Gold and Bitcoin.
