Meme that my math teacher put on our lessons:

[fatherphaniel]

this isn't an indirect to anybody and i don't want to start any fights BUT

if you genuinely think dan is being out of touch/hypocritical/whatever for being politically left wing and also having money/privilege, please read this

this is exactly the same as saying that men can't be feminists, white ppl can't be antiracist etc. just bc you're privileged by a system it doesn't mean you can't criticize it. in fact, you should criticize it, bc 1- ppl in power are more likely to listen to you and actually change something and 2- the more you educate ppl about the problems, the more ppl join the cause

also, when we think about who really benefits from capitalism, it's not ppl like dan and phil. if they stopped working tomorrow, they wouldn't have infinite money that they don't ever have to think about for the rest of their lives. they don't have an amount of money that could solve world hunger, climate change, poverty and every other fucking problem

you know who does? billionaires.

of course having money, even if it's not billions, makes you comfortable under capitalism. but if you have that, you see that other ppl don't, and you wish that everyone had access to what you have, you're gonna criticize capitalism. you're gonna hate billionaires that hoard wealth. you're gonna talk about your left wing politics

the real horror is ppl who don't want to lift a finger to the status quo

Lu au where everyone is the age of their game

Wild is 7

Warriors is 10

Sky is 13

Twilight is 18

Four is 20

Wind is 22

Time is 26

Legend is 33

Hyrule is 37

Warriors and Wild are LITERALLY child soldiers, Sky is in middle school (and is more than happy to travel as it means he has less homework to do…)

Twilight is a fresh adult and doesn’t know what he’s doing with his life

Four is still as short as he is in the comic. Also much to Sky’s dismay Four basically becomes his teacher so he doesn’t fall behind in his studies.

Wind finally can legally drink…. He’s the wine aunt. He’s a nut case. The kids love him. He and Time were babysitting Warriors during the WAR and they’re both still mad they put a like, 9 year old into a war.

Time is freshly married…. He’s as bad (if not worse) then Sky ever could be when it comes to being lovey dovey.

Legend is mad he has to go on another adventure after he’s been comfortably retired for a decade. He becomes the new old man, despite Rulie being older…. And btw Hyrule is still his little brother.

Hyrule is aging wonderfully much to everyone’s surprise. He looks 25. He still can’t read btw but he has mastered life in the wilderness. He is like a mountain lion, he can hide behind anything and sneak anywhere now. Give him a leaf and he’ll find a way to hide behind it and you’ll never see him….

They would’ve never found Hyrule if they didn’t have Warriors and Wild with them, and even then them finding Hyrule was more so Hyrule allowing them to find him so he could check on the kids.

Gale Math

So, we all know that in the epilogue, Gale tells Tav:

I love you.

And if you look at the datamined dialog files and read the dev notes, you’ll see this:

Devnote: With the warmth of having said this a thousand times before.

So, taking that statement as a FACT (which, you know, I’m certain it was intended to be…) we now have a solid numerical value to start with: 1000.

Next, we know that per the narrator at the epilogue start, it’s been 6 months since the defeat of the netherbrain; therefore it’s been 6 months since Gale and Tav got engaged/agreed to live together. We’re going to conclude that they have spent every day together since then.

6 months = 182.5 days

Now, assuming that Gale says ‘I love you’ to Tav on a relatively similar schedule each day (ex: when they first wake up, when Gale heads out to Blackstaff Academy, etc. etc.) we can make an equation:

1000 declarations of love divided by 182.5 days = the amount of times Gale tells Tav he loves them every single day.

We solve the equation and get 5.47945205

We round that down, and voila! We now have flawless mathematical proof that

Gale says ‘I love you’ to Tav an average of 5 times every single day

NEW IDEA

lazy little brother X scholar loser big brother

Little brother who falls asleep in class and hates doing his work. His big brother is trying to help him study, sitting up with him in his room, books and papers surrounding them. He’s so patient too, really trying to help his lil bro out.

“Come on, bud. You know the answer here, we just went over this. Try again.”

“Ugh I fucking hate this. Why can’t you just do it for me? Come on, please? You’ve done all these classes already, just do it for me.”

Big brother who smiles and laughs, ruffling his hair.

“That’s no way for you to learn. Come on you got this.”

Little brother who grabs his brother face and starts making out with him. His big brother being so gentle with him, gently tangling his fingers in his hair and kissing him softly. And then his brother pulls away, both of them red faced and panting but his little brother looks at him with half lidded eyes and a pout.

“I really wanna kiss more but my jerk of a big brother is making me do homework. Isn’t that just awful? And I’m gonna be so tired after all this work I’ll probably just fall asleep.”

“You’re a fucking brat.” Big brother who takes the book and starts doing all the work so he can fuck his brother quicker.

Doing the maths: Grian's failure at getting a mending book

lots of talk about maths and probabilities below the cut! but there's a graph and simple explanation at the end if you want to get the gist of it and are bad at maths.

(I am still young and learning maths, critique/advice always welcomed)

What are the odds of getting a mending book in Minecraft?

(I am assuming Grian has been doing all his fishing with Luck of the Sea 3)

The probability of a mending book is actually a bit annoying to estimate. The Minecraft Wiki lists fishing up an enchanted book as 1.9% chance. This is for ANY enchanted book. The Minecraft wiki talks about how the chance of an enchantment being selected is calculated. Mending has a weight of 2. Using the table, mending has a probability of 2/135.

However, Grian is looking for any book with mending, not just a pure mending book. Additional enchantments are calculated in a different way, involving RNG, which means it won't be as easy to model. Due to this reason, I'll just be using the odds for a pure mending book throughout.

TLDR: a mending book has a 0.028..% chance (2/135*0.019*100)

Grian's Data

According to this screenshot, Grian has used a fishing rod 5679 times. This number may not be fully accurate, as it includes the times he's fished other players, rather than just fished for items, but it is a good estimate.

To help visualise this data, with a median waiting time between catches of 17.5 seconds, Grian has spent over 20 hours fishing so far! He may have a problem.

Is this statistically significant?

Hypothesis testing (p-value approach):

H0: p = 19/67500 (the null hypothesis - he has no mending books because of chance)

H1: p < 19/67500 (the alternate hypothesis - he has no mending books due to different odds)

5679 trials, 0 mending books

X ~ B(5679, 19/67500) (binomial distribution, 5679 tries with a probability of a mending book being 19/67500, where X is the number of mending books)

p(X=0) (what is the probability the number of mending books being 0)

p = 0.2021473392

Now, the point at which data becomes significant is subjective. For instance, you *could* get a million heads in a row flipping a coin, it's not impossible, but at a certain point, you can begin to say "okay there's something not normal about this". For this approach, the closer the p-value is to 0, the more evidence there is against the null hypothesis . The p-value here is far above a significance level of 0.01, or 0.05, or 0.1. There isn't a clear line between significant/non-significant, but this is answer is quite a bit far from 0

With this, I cannot reject the null hypothesis.

Personal conclusion: this is not statistically significant, Grian is just unlucky.

Are other values statistically significant?

Gem's proposed 9000: results in a p-value of 0.079... more significant than Grian's number but I don't imagine Mojang would be too concerned. As said though, it's all subjective.

I am bad at maths, what does all this mean?

Here is a graph, showing what number of mending books you might have after 5679 tries. The height of the bar represents the probability of getting that amount. The numbers at the top are the (rounded) numbers I used in my calculation

The pink column is 0 mending books - like what Grian has! As you can see, it is less likely than getting 1 or 2 books, but not too uncommon to happen.

End conclusion: Grian has bad luck. Like, not as hilariously bad as he thinks, but still bad. If he keeps going, chances are he will get a mending book, but I think he should probably stop fishing because at this point he has a problem.

au where Sten helps parent the kid the Warden snatched off the streets, aka Imekari later known as Rook

[grandapplewit]

Harem AU where Shen Yuan transmigrates into one of Bingge’s wives shortly after he returns from the other world. After a brief (and frantic) realization that’s she’s a woman (and always has been, but we’re not getting into that right now), she delves deep into this harem drama she’s been thrust into. It’s not until she comes face to face with Luo Bingge that she realizes just WHICH harem drama she’s living, and immediately sets about making his life as good as she can manage. Oh, harem infighting is causing strain on his containers? Simply nudge Liu Mingyan and Sha Hualing into working together to manage the harem. The Northern Desert is hinging on disaster because of clerical neglect? One of her harem sisters has a brother who’s in need of a job, no stress. Luo Binghe’s kids are unruly and there’s no clear successor? She has a college degree and a little sister, teaching a dozen or so demonic children is a breeze! All in the name of giving Luo Binghe the time to find a new wife, of course, one who will disperse with the need for this sprawling harem, and once that happens she’s free to travel and document monsters to her hearts content.

art dump! (except I drew all these drawings at school during my math and language arts periods in the past week)

also some kiuan drawings^^ i wanna try writing a fic for this au sometime soon (i cant find any good ones on this au vro😭😭)

[inspired-lesson-plans]

Math, grade 7, Ratios and Proportional Relationships 7.RP.A.3: Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.

Essential Question: How can basic calculations of percent change influence major world events?

Do Now: Calculate the percent increase or decrease in each of the following equations. x = (28 - 17.9)/28 x = (41.5 - 57.7)/57.7

Class Discussion: Remind students about how to perform basic calculations of increase/decrease factors. Ask them whether this calculation would be more complicated if the quantities were dollars instead of just numbers (answer: no). Ask them whether this calculation would be more complicated if the quantities were billions of dollars instead of just dollars (answer: no). Show students that they just performed the exact same calculations that Donald Trump did in order to decide what tariffs should be put upon Indonesia and Thailand, respectively.

Finally, ask students whether important global trade decisions should be calculated with 7th grade math skills, or if perhaps this is insufficient given the severe consequences that could arise from such a dunning-kruger error.

Direct Instruction: Explain what a Dunning-Kruger error is, if for no other reason than to communicate how absolutely maddening has it is for legitimate experts who have dedicated their lives to nudging fiscal policy in the right direction and then watch as their president makes the worst decision possible on purpose.

Take a moment to explain the difference between an import and an export, so that students understand what these billions of dollars actually mean in the real world. Feel free to call out anyone who has ever questioned whether or not they would ever use this kind of math in the real world. Show them that it's happening right now, and make sure they understand how terrifying that is.

Acknowledge the variables: x: total exports from US to country i m: total imports to US from country i tau (τ): calculated % tariff on all imports to US from country i epsilon (ε): elasticity phi (φ): passthrough

Ask students what they think elasticity and passthrough mean, then show students this passage from ustr.gov:

Parameter Selection To calculate reciprocal tariffs, import and export data from the U.S. Census Bureau for 2024. Parameter values for ε and φ were selected. The price elasticity of import demand, ε, was set at 4. Recent evidence suggests the elasticity is near 2 in the long run (Boehm et al., 2023), but estimates of the elasticity vary. To be conservative, studies that find higher elasticities near 3-4 (e.g., Broda and Weinstein 2006; Simonovska and Waugh 2014; Soderbery 2018) were drawn on. The elasticity of import prices with respect to tariffs, φ, is 0.25. The recent experience with U.S. tariffs on China has demonstrated that tariff passthrough to retail prices was low (Cavallo et al, 2021).

Ask students if this clarified anything about what elasticity and passthrough mean. Most will say "no", but if anyone points out that multiplying 4 by 0.25 cancels them both out, reward them. That student is correct, because elasticity and passthrough have been arbitrarily assigned so as to make this calculation so simple that even Donald Trump can understand it.

Modeled Learning: Show how to apply these tariffs to popular imports such as raw coffee beans. For example, the USDA report of coffee imports from 2024 (page 6) shows that the vast majority of raw coffee is imported from Brazil.

A simple search with Perplexity.ai tells us that in 2024, imports (m) = $42.3 billion and exports (x) = $49.7 billion, so the reciprocal tariff would be (x-m)/m = (49.7-42.3)/42.3 = 17.5%.

Thus, all coffee imports from Brazil will automatically be 17.5% more expensive.

Be sure to highlight that this is happening to every country in the world, even those with total populations less than 1000.

Higher Order Learning:

Students should consider the following facts:

There is very little territory within the United States that can grow coffee.

Almost all coffee in the world is grown within what is called "The Global South", where the climate is warm and the labor is cheap.

The US exports significantly more (sometimes vastly more) to countries in the Global South than we import from them.

Students should then answer the following questions:

What will this universal tariff calculation do to the price of coffee?

Is there any way that US coffee companies can import the same amount of coffee as before without passing on the cost to consumers? Why or why not?

Do you think this tariff program will equalize imports and exports between the US and other countries? What other impacts could it have, good or bad, across the world?
