I’m so fucking nervous about going out in public especially to any social event presenting as a boy. My voice is low from my first puberty but I still have a girly voice and i don’t know how to speak masc. i don’t have much boy clothes only really the one outfit. My facial hair is light and patchy because I got laser and so i don’t get any shadow or anything anymore. I only have sports bras not a binder. I default to girl and keep hiding my genderfluidity. I get scared of people calling me detransitioner. But I have let the pendulum be stuck on girl side for far too many years and I need someone to make me go out and be a myself as a man. I need some kind of accountability as well. Like maybe hold me to posting a picture of a me at a bar as guy on my timeline idk just some kind of proof I have to show I didn’t chicken out. Can you help me…

Awww sweet boy needs to be told what to do? Don't worry baby, I got you.

You've been a naughty boy ignoring the fluidity of who you are, we're going to change that. Obviously you're aware of it, if you weren't, you wouldn't spend so much time on my blog. We just gotta show your masculine side some love.

Since you're nervous, we'll start off slow.

You're going to go to a store, preferably a thrift store. You're going to buy a T-shirt, slightly oversized second layer (jacket, flannel, etc.), and a pair of men's jeans. If you can, look for some work boots too.

When checking out, you're going to talk in a deep voice. Monotone.

When you get home, you're going to wash your new clothes and you're going to take your measurements for a binder. Then you're going to order a binder.

Once your new outfit is clean, you're going to change into it and take a photo. Either you're going to send an ask with the photo, or you're going to post it and tag me, your choice. Don't worry about your chest for now.

This is your first step, sweet boy. You're going to go into public more and more often like this. Once the binder arrives, you're going to use it. Short periods of time at first. Remember to stretch and drink water.

You're going to make me so fucking happy, and I know you want to make me happy. So I know you'll do all this.

Eventually, you'll get more used to the masculine clothes. Eventually you'll just start wearing them, thinking about me. Eventually you're going to touch yourself in the masculine clothes thinking about me. You're going to do it over and over again, thinking about how you're a boy for me, sweetheart. Eventually you'll practically train yourself to feel good dressing all masculinely for me. Like a good boy. Cause that's what you are when you're here. You're here often, I know you are, I see you in my notifications. You like being here. You crave it. You need it. You know that part of you will always be my sweet boy.

Random thought experiment that popped into my mind.

You are about to be transported to the stone age or the bronze age or something and you have time to prepare but you can't bring anything with you. How do you recreate the meter as precisely as possible? (Or any SI unit for that matter)

My Ideas:

Use the average diameter of a human iris.

This is probably the least variable measurement of the human body you can take. It does not vary much due to height or nutrition, and different ethnic groups typically will have vary similar size irises. By making it an average you can extract an additional decimal place of precision compared to just measuring your own.

Cons:

Irises are small compared to a meter,

It is difficult to get precise measurements and precise data.

Best case scenario still leaves you without that much precision.

Pros:

This can be done pretty much immediately.

Next method I thought of is using a pendulum of a specific period, tied to the duration of certain celestial events.

Effectively this is just extracting the meter from deriving the second. However I think units of time might be easier to derive as you can use the length of time of different celestial events as a timing mechanism which will be extremely consistent. You can use things like: how fast the moon transits the sun during a solar eclipse, or the length of a day from high noon to high noon on one of the equinoxes divided by a constant.

Pros:

Theoretical maximum precision is fairly high, as this can be cross referenced against several different measurements and refined over time

Cons:

Practical maximum precision is much lower, as taking measurements of time with neolithic tools is rather difficult. As is constructing an accurate pendulum.

You need to wait for celestial events and refine your measurements over the course of years.

Then the last method I came up with, which is rederive the meter the same way it was derived in the first place, by taking an exhaustive geographical survey of the radius of the earth and dividing by a constant.

Pros:

Theoretical maximum precision is fairly high, especially for the Kilometer.

True to history

Cons:

You need to conduct an exhaustive geographical survey of the earth...

You will be faced with the dilemma of whether or not to include the error that arose in the original historical survey that makes it so kilometers are slightly off from an arcsecond? of latitude/longitude.

Shipboard Timekeeping for OFMD Fans

Though the pendulum clock existed in 1717, the motion of a ship at sea kept it from working accurately on board. (I guess this was a hint that Prince Ricky’s gifts weren’t really for telling time.) Until the marine chronometer was invented in the 1760s, sailors used an hourglass (the glass) to keep time.

Accurate timekeeping was essential to navigation. To keep the glass on track, every day the captain would determine noontime using a sextant to measure the position of the sun overhead.

Bells and Watches

I couldn’t find any sign of the Revenge’s glass, but you can see the ship’s bell on the quarterdeck, a few feet behind the wheel. The glass would have been placed close to the bell.

The glass held only 30 minutes’ worth of sand, after which it was flipped over and the bell was struck. The first 30 minutes was one bell, then two bells after an hour, three bells after an hour and a half, and so on, until the bell was rung eight times to mark the end of 4 hours.

In the traditional system of watchkeeping used by the British navy, 4 hours was the length of a sailor’s shift, or watch, so eight bells marked the end of one watch and the start of the next. Thirty minutes into the new watch, the bell would be struck once, as the glass was flipped, and so on through all the watches. There were six watches in each 24-hour period.

First watch: 8 p.m.–midnight Middle watch: midnight–4 a.m. Morning watch: 4 a.m.–8 a.m. Forenoon watch: 8 a.m.–noon Afternoon watch: noon–4 p.m. Dog watch: 4 p.m.–8 p.m.

Most crews were divided into two groups (also called watches, e.g., the starboard watch and the larboard watch), with each group working in staggered 4-hour intervals: one watch on, the next watch off, and so on. This meant the sailors had to get their sleep in 4-hour chunks.

The schedule was arranged so that sailors worked a different series of shifts each day; for example, the starboard watch might work the first watch, the morning watch, and the afternoon watch one day and the middle, forenoon, and dog watch the next.

After a mutiny in 1797, the British navy divided the dog watch into two 2-hour watches.

First dog watch: 4 p.m.–6 p.m. Last dog watch: 6 p.m.–8 p.m.

With these shorter watches, the whole crew could eat dinner in the evening, with most crew members eating at 5 p.m. and those on the first dog watch eating at 6.

Of course, this doesn’t really apply to the mythical-pirate world of the Revenge, but it might give you some period-appropriate phrases for your fics if, like me, that’s a thing you’re into.

How to Tell Time Like a Sailor

Shipboard time was told in bells rather than hours of the clock. For example, British naval officers traditionally got up at three bells in the morning watch—5:30 a.m. (ouch). Pirate captains presumably got up whenever they felt like it. Sailors might also give the time as, for example, “six bells,” if it was obvious which watch they were talking about.

Flogging the glass is an expression that means doing something earlier than planned, like arriving early to an appointment. It comes from sailors shaking the ship’s glass to try to make the sand flow faster and shorten their watch. I’m guessing they did this out of sight of their superiors.

The phrase keeping a watch could mean “keeping your eyes peeled,” if for example you were assigned as lookout, but it also meant “working your shift,” whether that was at the the helm, the deck, or the sails. Some crew members, like the cook, were exempted because they had their own work to do—so Roach wouldn’t keep a watch; he’d be too busy cooking.

When the ship was in port, one unlucky crew member was assigned the anchor watch to keep an eye on the ship while everyone else was off duty. Given that they failed to do this even while at sea, I’m guessing the Revenge doesn’t bother with this one.

In the last section I mentioned the larboard watch. Port as an adjective—the port guns, the port watch—wasn’t in use until 1842; before then people used the word larboard. (Which had to be confusing because it sounds so much like starboard, but whatever, I’m no sailor.) So our 1717 crew would probably have said larboard instead of port. But this is a case where being historically accurate might confuse your readers, so I’d err on the side of not giving a fuck. No doubt David Jenkins would approve.

Analog Clock Parts

Utilizing Clock Parts to Express Your Uniqueness

Utilizing clock parts to build a timepiece is a means for a person to share some innovative uniqueness. Clock parts are generally picked separately, blending and matching in basically any kind of possible means, gave that their dimensions align and their styles are complementary. Clockmakers, whether amateur or expert, have found that this vast control over a product frees their spirit and opens them to a brand-new world where their creative imaginations preponderate.

However, simply throwing clock parts with each other haphazardly is apt to get old rapidly. One need to do a minimum of a minimum of preparing in the direction of the finished item, what its case should appear like in regards to style, color, and dimensions, whether to buy it or build it, and whether it will certainly hold on a wall surface or rest on a nightstand. This suggests some design job is required, which, with the appropriate perspective, can end up being another type of creative expression.

Actually, the instance itself might end up being the end-all, coming to be the central emphasis and overshadowing the timekeeping facet. This occurs when an old clock has actually stopped working and needs retrofitting, or when a family heirloom is geared up with a watch. In such instances, you'll want to maintain the hands and dial modest lest they detract from the centerpiece, and also a preassembled clock insert can be an excellent way to go.

On the other hand, if timekeeping is all-important, invest all your effort towards making the clock do all you want it to do. The starting factor is to choose the movement (or motor) according to the attribute collection you desire to carry out-- not only rotating the hands right into position at each moment but likewise various other things that please your fancy. By doing this, you recognize the capability up front and afterwards choose the different parts that flesh it out.

Remember that no person looks at the activity; instead, they gander at the dial and hands. So, depend on the activity to deal with the feature, however allow your uniqueness inspire the type in regards to style and shade. To put it simply, this is where some kind of statement is made; you identify its degree of beauty, boldness, and mindset.

Now, do not go wild and have the hands and dial make contradictory statements, which people would certainly just discover confusing. This suggests that these parts need to not be picked separately yet together. They need to match in size, and they need to also integrate in color and design; as a matter of fact, aim to unify ball of wax with the framework.

You can reveal a great deal of uniqueness (many stylistic choices) with simple timekeeping, yet you can also do so with the extra unique motion features. Time extension of the period past 12 hours is one way (to 1 day, 1 week, or 1 month). These require a particularly calibrated dial to couple with the motion, and perhaps an extra hand to direct at the added details.

Another electrical outlet is to use weather activities, either the temporal display screen of tide degree (alone or integrated with normal timekeeping) or sensations that need to be measured. Sensors maintain continuous track of humidity, temperature level, or pressure, and the software program in the motor transforms the number right into a single hand setting relative to a range printed on the dial.

A 3rd strategy is to apply novelties such as aesthetic pendulums or artificial chimes. These emulate older clocks and supply a certain level of nostalgia. Variations on whether you use a second hand, or just how it runs, is one more concept. clock parts

Basically, the clockmaker is offered great deals of choices for creating a watch that is attractive and appreciated by others. There really are no limitations to utilizing clock parts for expressing your uniqueness.

Digital Clock Movements versus Mechanical Ones

Digital clock movements are modern engines, as it were, or motors that consistently place the hands for accurate time informing. Mechanical clock movements are their predecessors, using gears and numerous devices to revolve the hands right into area. The standard display was analog hands superimposed over a dial, whereas electronic displays might be analog or digital, utilizing LEDs.

Thus, clock movements execute the same function, whether digital or mechanical, and they often look primarily the like well. Nonetheless, the innards of the two types are rather various, with the mechanical motors employing hanging weights or coiled springtimes as their force, converting prospective energy right into kinetic by rotating a flywheel. Rate of turning was managed with using a pendulum and escapement device.

On the other hand, the force behind the digital movement is quite various, basically applying a change in voltage throughout a quartz crystal, which responds by rapidly shaking at a certain powerful regularity. It is fairly uncomplicated to keep track of the resonances and count their pulsing in real time. Since the vibrating regularity is so exact, the gathered pulse matter (kept in digital signs up) is a very accurate step of elapsed time.

However, since the running number of pulses is a lot greater than the number of secs passed, software has to be set up to partition the total amount to the 2nd array and kept in a separate register. (Mechanically, the mix of pendulum and escapement guarantees a rotational modification of one tick per second.) Either mechanically or online, with the passing away of every second the clock movement subtends the pre-owned an extra six levels of arc.

More registers monitor mins and hours, each ticking up by one when the previous register reaches sixty. Going across the minute limit causes the equivalent hand to get revolved a tick, and the hour hand gets revolved at one-twelfth that rate. The hands will certainly all align once again when the duration is gotten to.

One of the most typical period is twelve hours (resetting two times a day), yet movements with longer durations are likewise offered. Of note are periods of 24 hr, 1 week, 1 month, and 24-hour plus 50 minutes (representing the lunar cycle for tracking trend level). Many of these require an extra hand and a dial calibrated to the movement.

For example, the weekly period utilizes a dial with the names of the 7 days radiating out from the facility for concerning half the dial distance. The added hand rotates regarding 51.4 ° at midnight to indicate the next day. The other special time-extended movements utilize similar hand and dial plans.

Digital clock movements can being reconfigured to track and show specific weather phenomena such as regional humidity, temperature, or barometric pressure. These things aren't routine, and sensors need to be utilized to register changing dimensions in real time. The dial is essentially a range arching from one end to the various other around the dial circumference, and the single hand is turned to the mark corresponding to the measured value.

There are (or at least have been) mechanical movements for tracking weather occasions also, but they often tend to be more troublesome than their electronic counterparts. This is since thoroughly developed tools have to be built to map analyses right into hand setting, whereas electronically the entire process is taken care of in software.

We have concentrated on timekeeping functions, yet both sort of motors are capable of featuring uniqueness such as playing chimes or oscillating pendulums. They differ in terms of approach but the effect is basically the same. These tools have been around in some type for centuries, and it can be beneficial to have an understanding of just how electronic clock movements run versus mechanical ones.

where your spade is turned, pt. 1

The first physics course Rose takes in Pete’s world is very nearly the death of her.

Maybe that’s overstating it.  But not by much, in the long run. The pudgy young lecturer brightly speaks about motion, about measurement, about change.  How what they’ll do in this course is the practice of describing reality through equations.  He drags a student to the front of the hall, places a wheel in their hands, spins them around on a stool.  Tracks a pendulum’s periodic motion with video software.  Makes jokes about friction and thrust and how physicists do it better.   Rockets himself across the stage with a handcart and a fire extinguisher, whooping with glee as he holds his flat cap tight to his head.

Amidst the barely younger students in the university lecture hall, Rose feels immeasurably old.  She’s seen the death of the Earth, she’s seen monsters and aliens and the flow of time—and here she is, taking science and tech classes in order to work her way into some kind of understanding of what the science and tech team is talking about when they begin muttering in their odd science and tech lingo while she delivers ream after ream of paperwork that she can’t make heads or tails of.

“I mean, you could just wing it,” Mickey’d said, around a mouthful of chips from the basket they’d been splitting after a mission.  Well, after Mickey’s mission.  After Rose’s clerical duties. “Those lab nerds’d wet themselves to help you out, they think you’re hot.”  Then he’d paused, shrugged.  “But, you know—could be useful, for you.  Some university under your belt.”  He doesn’t attempt to take hold of her hands, which she has wrapped tightly around her drink, fingers white and tense.

In case this doesn’t work out, he’d carefully not said.  In case you don’t find him, and you don’t wanna be stuck at Torchwood for the rest of your life.

Hello 🌻 could do the birthday language of January 21st pretty please 💛

Language Of Birthdays: January 21 - Aquarius

[You can find the rest of the series here; or check out my masterlist]

The Day Of The Frontrunner

Those born on January 21 are headed for the top and when they reach it they usually know how to stay there. Until those born on this day realize just how ambitious they truly are, they may suffer a great deal of unexplained frustration. January 21 people are tough individuals with lots of drive, but also have an easier, pleasure-loving side which can come to dominate their time and energy if they lose direction. The most successful people born on this day are able to integrate these two sides of their personality. However, many January 21 people swing like a pendulum from a more relaxed to intense state and back again, seemingly unable effect a synthesis of the two.

Sooner or later, a desire to lead the pack emerges in January 21 people. If they do succeed in reaching the top in their chosen field, relinquishing such a position may indeed be difficult for them. Competing interests, poor health, advancing age, even unhappiness with the work itself may not dislodge them. If they are brought down from their perch, it is most often due to their pleasure-loving side which can dull their competitive edge.

Most January 21 people are not cut out to be leaders in the long haul, having neither the ruthlessness nor innate authoritative sense generally required. Careers where they may strive to be the best through improvement of their talents and skills are thus preferable to careers within a highly politicized or hierarchical structure.

January 21 people have a large measure of star quality that attracts others to them. They are often not only trendsetters at work, but also in their social circle. They have a knack when it comes to handling people, and are highly persuasive when offering their views or making suggestions. Those born on this day who occupy a high place in society usually have the common touch, and therefore mix well with people from all walks of life. Their exciting, colorful, active and passionate nature makes for an undeniably attractive sexuality. Heartbreakers of a kind, they can sometimes hurt others by being too caring, when it would be better to just say goodbye. Most often, however, friends and lovers are happy to have known them, even for a short period, as January 21 people enrich the lives of those they spend time with.

For all of their public pizazz, January 21 people are somewhat retiring, rarely liking to mix their public and private lives. They normally have a home or hidden retreat where entrance is granted to but a privileged few. Perhaps their greatest problem lies in making up their minds what it is they really want from life. Until they do so, they will, like fireflies, disappear and reappear from one spot to the next.

Strengths:

Colourful

Attractive

Open

Weaknesses:

Indecisive

Pleasure-bound

Hurtful

Advice

Those born on January 21 are generally open to suggestions for improving their health. In particular, sensuous activities, such as massage, are attractive to them. Their physical side takes quite naturally to exercise, as long as not too much discomfort is involved. Also in the area of food. January 21 people are open to suggestions about eating in a more healthy fashion. Sexual expression on a regular basis and being admired for their physical attributes are both very important to January 21 people. Health may be the area in which an important connection between their ambition and their love of repose and sensuality can be effected. Partners should be sought who are able to share their lifestyle as much as possible.

Expect the very best from yourself

Beware of a tendency to drift; keep moving with a purpose

Don't hold on too long, or relinquish your freedom

The National Weather Service Began as a Crowdsourcing Experiment

The National Weather Service Began as a Crowdsourcing Experiment

Illustration by Lucille Clerc

For centuries, humans complained about the weather. In 1848, the Smithsonian Institution decided to do something about it. Weather conditions had been considered to be either God’s will or explainable only by homespun nostrums like “Clear moon, frost soon” or by observing, say, the behavior of ants, which don’t like rain. The Farmer’s Almanac promised readers more accurate forecasts when it debuted in 1818, but even those predictions were determined by a “secret formula.” And still are.

Joseph Henry, the first Secretary of the Smithsonian, tried something new: crowdsourcing. The Institution handed out weather monitoring equipment such as thermometers, barometers and rain gauges to 150 volunteer observers across the country. Each day their localized reports arrived by telegraph, and the Smithsonian generated a national weather map that it displayed on the National Mall. The map became a popular attraction. Tourists who viewed it, Henry noted, “appear to be specially interested in knowing the condition of weather to which their friends at home are subjected at the time.”

An amusing novelty, but no consolation for those pioneers crossing North America, the continent with some of the most violent weather on earth. Only two years before, 42 members of the Donner Party perished in an early Sierra Nevada snowfall they had no way of foreseeing.

In time the number of Smithsonian volunteers grew to more than 600. Technology improved, and slowly auditors found ways of determining what rudimentary climate data collected about the skies over Denver might soon mean to the skies over Chicago and New York as weather moved east. Reports about temperature, humidity, wind and cloud formations flooded in. Still, data didn’t always reach the right place at the right time. For example, on the Great Lakes, 97 ships were lost in one four-day gale in 1869.

Secretary of Agriculture Howard Gore, left, and Charles Marvin, chief of the U.S. Weather Bureau, view a map of weather stations, c. 1924. The bureau was the forerunner of the NWS.

In the year following that tragedy, President Ulysses S. Grant signed a resolution into law creating the Division of Telegrams and Reports for the Benefit of Commerce. The Smithsonian’s weather observation network was turned over to the Army, which began issuing official forecasts capable of seeing, if hazily, 24 hours ahead. The threat from sudden weather disasters diminished. Ship-borne commerce vastly improved; doing business in America increasingly meant knowing the weather ahead. The division would evolve into the National Weather Service, part of the National Oceanic and Atmospheric Administration in the Commerce Department.

The first U.S. weather balloons took flight in 1909, improving the study of temperature, humidity and air pressure. Another breakthrough came in the 1920s when the balloons were equipped with radio transmitters, and real-time observation of the stratosphere became possible. For the first time, researchers observed not only the width of a weather system but also its height. During World War II, radar operators noticed patterns of interference on their screens aligned with heavy weather—and the science of radar meteorology took off, and is still in use today.

So confident were some mid-20th-century weather mavens that they speculated the heavens could be manipulated by chemically altering the atmosphere. Bespoke weather, they believed, would bring rain to farmlands, snow to ski resorts. That quixotic dream didn’t pan out, however, and Americans today are delighted to settle for smartphone weather apps, powered by NWS computer and satellite data, that give accurate information they can access instantly to stay safe. The average three-day hurricane landfall forecast can now pinpoint a much more specific swath of at-risk coastline—100 miles in 2020, compared with 300 miles in 1990—reducing the stress and cost of false alarms. Over the same period, the average tornado warning time has risen from 5 minutes to 8 to 10 minutes.

Will climate change erode our confidence in everyday weather prediction? Not in the short term, says Beth Carpenter, a meteorologist and co-founder of Thermodynamic Solutions, an Indianapolis-based firm. “Climate change itself won’t affect weather modeling because the time scales are vastly different. We are forecasting on a much smaller time scale, usually only out to three months at a time for seasonal forecasts at the longest range. Climate periods are defined as average conditions over 30 years.”

North America’s weather is no less violent than it was when the Donner Party, oblivious, set sail in their prairie schooners before succumbing, victims of what Joseph Henry would call “the problem of American storms.” But the NWS, now with 4,000 workers, will keep finding safer ways for us to live with them. That’s a sunny forecast no matter where you are.

Five Things You Need to Know About the Deep Space Atomic Clock

We are set to send a new technology to space that will change the way we navigate spacecraft — even how we’ll send astronauts to Mars and beyond. Built by our Jet Propulsion Laboratory in Pasadena, California, the Deep Space Atomic Clock is a technology demonstration that will help spacecraft navigate autonomously. No larger than a toaster oven, the instrument will be tested in Earth orbit for one year, with the goal of being ready for future missions to other worlds.

Here are five key facts to know about our Deep Space Atomic Clock:

1) It works a lot like GPS

The Deep Space Atomic Clock is a sibling of the atomic clocks you interact with every day on your smart phone. Atomic clocks aboard satellites enable your phone's GPS application to get you from point A to point B by calculating where you are on Earth, based on the time it takes the signal to travel from the satellite to your phone.

But spacecraft don't have GPS to help them find their way in deep space; instead, navigation teams rely on atomic clocks on Earth to determine location data. The farther we travel from Earth, the longer this communication takes. The Deep Space Atomic Clock is the first atomic clock designed to fly onboard a spacecraft that goes beyond Earth's orbit, dramatically improving the process.

2) It will help our spacecraft navigate autonomously

Today, we navigate in deep space by using giant antennas on Earth to send signals to spacecraft, which then send those signals back to Earth. Atomic clocks on Earth measure the time it takes a signal to make this two-way journey. Only then can human navigators on Earth use large antennas to tell the spacecraft where it is and where to go.

If we want humans to explore the solar system, we need a better, faster way for the astronauts aboard a spacecraft to know where they are, ideally without needing to send signals back to Earth. A Deep Space Atomic Clock on a spacecraft would allow it to receive a signal from Earth and determine its location immediately using an onboard navigation system.

3) It loses only 1 second in 9 million years

Any atomic clock has to be incredibly precise to be used for this kind of navigation: A clock that is off by even a single second could mean the difference between landing on Mars and missing it by miles. In ground tests, the Deep Space Atomic Clock proved to be up to 50 times more stable than the atomic clocks on GPS satellites. If the mission can prove this stability in space, it will be one of the most precise clocks in the universe.

4) It keeps accurate time using mercury ions

Your wristwatch and atomic clocks keep time in similar ways: by measuring the vibrations of a quartz crystal. An electrical pulse is sent through the quartz so that it vibrates steadily. This continuous vibration acts like the pendulum of a grandfather clock, ticking off how much time has passed. But a wristwatch can easily drift off track by seconds to minutes over a given period.

An atomic clock uses atoms to help maintain high precision in its measurements of the quartz vibrations. The length of a second is measured by the frequency of light released by specific atoms, which is same throughout the universe. But atoms in current clocks can be sensitive to external magnetic fields and temperature changes. The Deep Space Atomic Clock uses mercury ions - fewer than the amount typically found in two cans of tuna fish - that are contained in electromagnetic traps. Using an internal device to control the ions makes them less vulnerable to external forces.

5) It will launch on a SpaceX Falcon Heavy rocket

The Deep Space Atomic Clock will fly on the Orbital Test Bed satellite, which launches on the SpaceX Falcon Heavy rocket with around two dozen other satellites from government, military and research institutions. The launch is targeted for June 24, 2019 from NASA's Kennedy Space Center in Florida and will be live-streamed here: https://www.nasa.gov/live

Guys guys guys

I want to share a thread from one of my ADHD Support groups on Facebook. Date of post February 27 2020.

Here's the initial question:

"ADHD has very similar traits to autism ((from what I have gathered at least)) and in support/representation are always grouped together.

Do you think ADHD should be clasified as on the autism spectrum? Why or why not?

What positive or negative effects ((May it be treatment, understanding, research, or a social aspect)) do you think it would have if it was?"

And here's some of the comments:

1. "In lots of conversations I have had, this topic has come up, and the conclusion we usually reach is that eventually, both ADHD & ASD will be reclassified into something like “Executive Function disorders” and the spectrum will just be broader, rounder, and more inclusive of all the beautiful facets of our Neurodivergent brains" 🧠 #NeurodiverseSquad

2. "I am diagnosed with both. In fact I received my ASD Level 1 (aka "condition formerly known as Asperger's") diagnosis just 4 weeks ago.

Here's the thing: they are in no way mutually exclusive. In fact this was the mistake I made when I had my initial assessment that diagnosed the ADHD - (wrongly) assumed that if I had one, I couldn't have the other. This is in fact not true, and recent research shows that between 1/3 and 2/3 of people with an ASD may meet criteria for ADHD as well. However, the reverse is not true - this is because (as current research shows) 6-7% of the population have ADHD, and only about 1.5% are on the autism spectrum. So somewhere between 0.5 and 1% of the total population (likely) have both. Most people with ADHD do not also meet criteria for ASD.

Basically, the way these two things are diagnosed are based on totally different criteria. ADHD is about, well, attention and more broadly executive (dis)function. It's a readily measurable, testable condition that boils down to certain specific pathways in the brain working much slower (and/or much faster) than the average population.

ASD is, well, different. The current diagnostic criteria all revolve around the following things.

1) Significant impairments in social communication

2) Patterns of pervasive repetitive behaviour (and thoughts)

3) Unusual sensory interests, and/or sensory hypo-/hyper-sensitivity well outside typical ranges

To be diagnosed with autism spectrum disorder, it's not enough to just "experience those things sometimes". There has to be a pervasive, life-interfering pattern of at least 2 of those three things, which cannot be explained by any other underlying cause or condition, AND can be demonstrated going back to that person's earliest childhood history, and preferably family history too.

Can those things describe a person with ADHD? Totally! Are they how we define ADHD? Nope!

The neurology of ADHD is pretty well understood today - scientists very good idea what ADHD "looks" like in the brain and how it functions. We don't know everything but we know a lot compared to, well, basically anything to do with the brain. It's one of the best studied neurological conditions, period.

The neurology of autism is, well...... much murkier. There are multiple theories. The current ASD diagnosis was a bit controversial when it was totally revamped in 2013, lumping things like Aspergers and PDD-NOS under a single standard. Not everybody was a fan of that, although at the time research in the field was pointing more in that direction - but right now the pendulum of scientific consensus seems to be swinging the other way, thanks to more extensive brain studies finally being done. It's still early days, but there is now the possibility that what we call autism/ASD today may turn out to be a group of several distinct neurological conditions, one of which may in fact be a close relative of ADHD, mechanically speaking. But a LOT more research needs to be done before we can say anything for sure. Early days.

In any case, the best takeaway from this looooooooong writeup is:

You can be both. You can be neither. If you are on the autism spectrum, there is a very good chance you might also fit the diagnosis for ADHD - but if you have ADHD... while you are statistically more likely to be autistic than the average person, it's still a much longer shot. Don't rush to conclusions, and talk to specialists. Neither of these conditions should be either a "badge of honour" or a "badge of shame" - cause it's not a badge, it's a complex part of how your brain works in real life. Between 1-2 out of every 3 people with autism MAY have ADHD - whereas only 1 out of somewhere between every 6 and every 14 people with ADHD is autistic.

It's not possible to rule out a neurological link between the two, but it's not going to be a link that defines either one of those conditions. It's more like the link between ADHD and depression - us ADHDers are far more susceptible to depression than the average person; but faaar from every depressed person has ADHD.

Truthfully - with autism spectrum, before anyone goes running off for diagnosis... speaking from personal experience, you gotta ask yourself what you are hoping to get out of it first. I'm glad I did, but in some ways it's a harder pill to swallow than ADHD - especially because there are no actual pills to swallow for treating it, nor therapies designed to help newly-diagnosed autistic adults. Young kids diagnosed with autism get a big boost from intense learning therapy, which helps them catch up on things like social skills and avoid a lot of the associated trauma - but there's not much out there for the adults, since you can't really get a do-over on your childhood and the damage (as in, trauma) is already done long ago. It's just a thing you find out about yourself, and while it can be empowering - it can also be a bit overwhelming and leave you with more questions than answers about yourself. That's about where I'm at with it, anyway!"

-

Now, having both, I'm inclined to agree with these. I myself have wondered here if ADHD could be ever put on the greater Mobius strip spectrum of Autism. But a comment someone here made, about the two being on the same Axis but not spectrum had me rethinking. A bunch of us activists with both are still waist deep in research, and I'm tossing these ideas out to chew on.

Basically, Tumblr is full of folks who look at an Autistic or ADHD post and say "wait, I relate to this but I only have one or the other!" And 80 percent shared comorbidities means a huge relation. They're cousins. I call ADHD Autism's excitable twin. It's exempt from allistic fuckery for me. I like to nickname it Cognitive Attentive Tempo Syndrome. (CATS!) My ADHD therapist likens it to being a polar bear in Florida, with meds being water wings. So there's enough overlap that the primary traits for one could be secondary traits for the other.

In conclusion: Yes, this relates to you. Enjoy your executive function dysfunction Neurodivergent Umbrella Axis Family Reunion.

Question: are fictitious forces comparable to imaginary numbers? Is it that the concept of centrifugal force allows certain math problems to be solved, even though it doesn't actually exist, like the number i? or am I way off base? [signed: a confused bio major]

[Image description: a second tumblr ask from archaeopter-ace reading, “(though I definitely agree that the nuance of 'centrifugal force is a fictitous force' is absolutely lost in most physics classes, who are either 100% for or against its existence, and treating it like it's real means kids won't understand how force works properly. Force has to come from somewhere, it doesn't just spring forth from the ether because you need an opposing force to explain what you're seeing)”]

Okay, so bear in mind that I’m an upper division undergrad, and it’s entirely possible that I am missing some aspect that is taught in graduate level courses. Also, whenever I use the word “you” in here, I am using the general you.

So, first off, I’d like to clarify the reason why the imaginary number i* is used in many physics cases is the simple fact that it’s easier to take the  integral/derivative of e^(iθt) than it is to take the integral or derivative of sin(θt) or cos(θt). However, no matter if you choose complex exponentials or regular trigonometry, you will get a real answer. This is used for things that are periodic and repeating. Examples of this being used are masses on springs and pendulums, circuitry, and likely many more cases because so many physical systems can be measured as simple harmonic motion.

* Not to be confused with the unit vector î. This is associated with the very real x-direction.

However, in quantum mechanics, the imaginary number i is used for multiple reasons. It’s sometimes used as an exponent of the natural number e in order to avoid using trigonometry for the wave, but it is also multiplied across the entire equation Ψ(t) so that the solution is a real number.

Treating the centrifugal force as a force never makes the math easier, in my experience. However, depending on the frame of reference (aka point of view) you choose, you may or may not need to treat the centrifugal force as a force in order to make the math work.

For example, have you ever been spinning around a mass on a string above your head and then suddenly you let go while still trying to maintain that rotating circle? The mass you’re spinning flies off in a straight line in the exact opposite direction. This is due to inertia (aka the thing that keeps objects in motion staying in that same motion and objects at rest staying at rest unless an outside force acts upon them), although some may call this the centrifugal force. As long as you are in an inertial frame of reference (aka you aren’t accelerating), then the centrifugal force is not a force, but rather the effects of inertia. Newton’s laws of motion work perfectly to describe the motion of you and the object. It is much easier to deal with an inertial frame of reference than a non-inertial one. However, there are situations where the observer is in a non-inertial frame of reference.

Have you ever been driving and you made a hard right turn, only to feel your body shift towards the left of the car? That is not something that Newton’s three laws of motion can explain, not from your accelerating non-inertial frame of reference. They can’t mathematically model how you’re moving... not unless you invent a force that is pulling you towards the left side of the car! In that case, the centrifugal force is something to be treated as very real, and is equal to the mass of the object (aka you) times the squared angular velocity times the distance from the axis of rotation. Of course, someone sitting on the sidewalk (and not accelerating with respect to the Earth) watching you can conclude that you’re experiencing the effects of inertia and that there is no centrifugal force acting upon you.

Now, technically, one can make the claim that gravity is just as real as fictitious forces found in non-inertial reference frames. After all, if you’re in a windowless room and you feel like you’re feeling gravity like you would on Earth, how can you be sure you’re actually on Earth and not just accelerating through deep space at 9.807 m/s²? Einstein made that exact claim and it’s now known as the equivalence principle. However, I would ignore this unless one has to deal with general relativity.

(Other case of a fictitious, non-centrifugal forces in cars include how when the driver suddenly slams the gas pedal, you feel yourself thrown back against the chair. From an inertial frame this is the back of the chair accelerating forward into you, but from your non-inertial frame of reference there seems to be a force shoving you backwards. Likewise, when the car suddenly stops (whether intentionally or unintentionally), you’re thrown forward. From an inertial frame of reference, this is your inertia causing you to move forward even as the car stops. From your non-inertial frame of reference, it seems that there’s a force throwing you forwards. This is why you need to wear a seat belt, because even if you don’t get in trouble with the law for not wearing one, the laws of physics will get you if you’re in a bad enough crash.)

TL;DR: Yes, the concept of centrifugal force allows certain math problems to be solved, even though it doesn't actually exist.

5. The Principle of Rhythm:

Everything flows, out and in; Everything has its tides; All things rise and fall; The pendulum swing manifests in everything; The measure of the swing to the right is the measure of the swing to the left; Rhythm compensates.

Between the opposite poles of the principle of Polarity, is the pendulum swing of The principle of Rhythm. This principle embodies the truth that everything exists in a measured motion, from here to there, moving in and out, swinging backward and forward, the rise and fall of the tides, ebbing and flowing and never truly sitting still. Never stopping, always changing.

This principle controls the cycle of life and death, creation and destruction, rise and fall, and of course manifests in our mental states.

When you are in tune with the Principle of Rhythm and understand that every mental state exists in Rhythm, always ebbing and flowing, you can learn to use this principle to your advantage by polarizing yourself to the degree you desire. Then, through awareness of this principle and how it manifests, holding yourself there to keep the pendulum from swinging you backwards to its extreme.

Imagine going to an event that you know holds a lot of emotional significance for you, and checking in with yourself there. Knowing, you are experiencing a high and that this state is unsustainable, you can slot in time for transition to keep yourself from crashing, knowing the Principle of Rhythm is affecting or will affect you. Likewise, with times of stress and grief, giving yourself time to return to neutral before ramping back up again.

Know that things you lose, will come back, and that things you own now, will disappear later.

Being able to appropriate these smooth transitions can be the difference between days of recovery (mentally, physically, and emotionally) and smooth grace periods between times of intensity. Knowing when to retreat and when to return is one of the many keys to self mastery.

Through heightened awareness gained by understanding this principle, you can experience transcendental states of consciousness to rise above the swing of the pendulum. Rhythm will have an effect on you one way or another, but with awareness you can use it to propel you forward and ride it back to recovery.

All people who experience self-mastery do this to some degree, but those who exert their will upon this principle are able to act from a place of purpose as opposed to letting the pendulum swing them into reactivity.
