Pi Day - Blog Posts

Hope I'm not too late, have some Pi Day memes.

Happy pi day!! I made and had bumbleberry pie today 🤤

Lowkey almost forgot but it's ok

Who else remembers "All your pie" from legendary frog 2002? I'm showing my age haha this is back from before YouTube

Cut some delicious pie for yourself! Oh, and keep the knife. You're gonna need it soon.

ok actual post

happy pides of march

We’re really having a holiday alignment this weekend. Purim, Holi, and Pi Day are all today. And then tomorrow we have the Ides of March. And on Monday is St. Patrick’s Day. And pretty much this entire month is Ramadan.

HAPPY PI DAY!!

happy Pi day everyone

Happy Day That Krabs Fries

that's it, I can't take this anymore. I'm so fucking done. I feel like a non-Christian person in fucking December. Listen, people: the Ides of March is a FINE holiday, it's fun and nerdy, I like it - but I've seen like 6 memes for it in the last 3 days and not a Single one for its sibling nerd holiday, MARCH 14, aka 3/14, aka

PI DAY

3/14, optimized at 1:59 and 26 seconds, AM or PM (3.141592653589793238462643383279502884197169399... that's as far as I ever memorized).

Celebrations around the world - as is ONLY appropriate for the one and only celebration of the constant ratio of the circumference of a circle to its diameter!

And the radius to its area, and the radius of a sphere to its volume and surface area, AND one of the key five numbers in Euler's Identity, aka e^(iπ) + 1 = 0, aka the sexiest, simplest mathematical equation in the world.

There's going to be an HOUR-LONG LUNAR ECLIPSE this year, visible throughout East Asia, Australia, North and South America, and most of Africa and Europe!

It's even Albert Einstein's birthday!

Is Pi Day underrepresented because math is continuously viewed as the subject it's culturally acceptable to hate, where even "boring" history and "pretentious" literature can be lauded? Does every holiday need a centuries-famous play in order to get attention these days? DO PEOPLE NOT WANT AN EXCUSE TO EAT SAVORY PIES FOR DINNER (PIZZA, SHEPHERD'S PIE, ETC) AND SWEET PIES OF FRUIT AND/OR CHOCOLATE FOR DESSERT??

So help me god I'm going to start making a new Pi Day meme every time I see an Ides of March meme. I'm going to blaze them. PRETENDING TO KILL A DICTATOR IS FUN, BUT IT IS A TREAT BEST PAIRED WITH THE ELEVATION OF SCIENCE!

Knives! Get your Knives here for no particular reason!

Get em while they're cold, get em while they're sharp!

Special discount if your name is Brutus for no reason in particular!

Why am I only learning about the Mid-March mini holiday season here on Tumblr? We've got Pi day, followed immediately by the Ides of March, followed immediately by the day Homura resets the timeline to in Madoka Magica, and no one told me!

Cosmic Piece of Pi!

Did you know that pi is involved nearly anywhere you look? We’re not talking about your favorite pastry! Pi (also written as the Greek letter 𝞹, or the number 3.14159...) is an irrational number, which means it can’t be written as a simple fraction like ½. It is the ratio of a circle’s circumference (the distance around its edge) to its diameter (the distance across it) and will always be the same number, regardless of the circle’s size. Here are some places you can find pi in the universe around us!

Our Transiting Exoplanet Survey Satellite, TESS, watches slices of the sky in its hunt for worlds outside our solar system — how many exoplanets are in its night-sky pie? Last July, TESS scientists created a mosaic of 208 images of the southern sky. At that time, it contained 29 confirmed and 1,000 possible exoplanets, and we’re still studying the data to find more. Since this awe-inspiring image is of the southern hemisphere (or half of a 3D circle), there will always be pi! Every slice contains something delicious for scientists to study.

Pi recently played a crucial role in new discoveries about Alpha Draconis, a well-studied pair of stars. After discovering these stars regularly eclipse each other, pi helped scientists learn more about them. Scientists detected the eclipses while monitoring the brightness of Alpha Draconis for periodic dips that could’ve been caused by planets passing between the star and us. Instead of a planet, though, researchers found that its smaller partner in crime was passing in between us and the larger star for about six hours at a time! 💫

Pi comes in handy as we learn more about these two stars. Knowing the percentage of the decrease in Alpha Draconis’ light and the formula for the area of a circle (A=𝞹r2 — or area equals pi times the square of the circle's radius), scientists can predict the sizes of both stars.  Because stars typically orbit in an elliptical (or oval) shape, pi also helps scientists use the detection of these eclipses to figure out the orbits of the two stars!

So far we’ve seen pi in many places! But it's also interesting to look at where pi can't be found! We mentioned earlier that many orbit calculations involve pi … but not every one does! Pi does not factor into calculations of hyperbolic orbits — orbits that aren't complete, or don't return to where they started — the same way that it does with elliptical orbits! This is most commonly seen with comets. While many comets orbit normally in our solar system, some oddballs just pass through, like the interstellar ‘Oumuamua that zipped passed us in 2017. ☄️

Perhaps the most popular place you may find pi is in the shape of a typical pie! While NASA’s Fermi Gamma-ray Space Telescope studies gamma-rays, and not blueberries, we think this cool Fermi pie is worth sharing for Pi Day!

Find more ways scientists look up at the night sky and use pi here. And now, don’t be irrational, and go have some pi(e)! 🥧

[Hey, That’s Her] The Riemann Sphere is Her Mirror on the Wall

                                   MBC 드라마 《신입사관 구해령》 (2019)

There may be such a woman.

For at least eleven hours a day, her analytical, artistic, emotional and ethical minds are collectively locked up in a Taylorist cell block where the mantra is familiarly simple: Don’t question, don’t tell. Every reasonable client is aware that this is a dog-eat-dog world, so it is up to him or her to look out for personal interests not yet covered by contract law or even fiduciary law. If you value your principles and dreams over your corporation’s needs, you are a selfish hypocrite. Oh, and complain all you want at the water cooler; just remember to put back your angel mask and keep your head low at meetings.

That much is not really astonishing. No one in this place is a one-day-old. What stuns more is the utterly dim calaboose she toils away at her daytime lockup to return her body to every night, where broken bottles and suspicious pools of liquids bedeck the streets, literal rock concerts never cease, homeless druggies openly spread their limp bodies on pavements, and drunken Cinderellas and Cinderfellas bang on random doors when the clock strikes twelve. 

Change might come with time but, given a burgeoning workload and an increasingly creepy cardiac rhythm, it must come soon. So, one night, she decides that if all jobs are this suffocating, she might as well take the best-paid one. It’s time to head back to graduate school, except that, this time, economic logic shall prevail over passion and intrigue.

As part of her research on Wealth and Investment Management MScs, she hunts down sample class videos from different business schools. Nestled among the suggested clips accompanying one search result, though, is a familiarly curious title that hypnotizingly whispers to her, Shopaholic Louis-style. It is the name an adviser, frowning over yet another overloaded course plan from her, pressed her into canceling out all those years ago right when meeting times for the semester did not conflict with those of her core classes. And soon, before her eyes, is an entire playlist for her narrowly missed destiny.

What harm could playing the introductory video at 2x do? Business schools’ admissions websites would not vanish in 30 minutes’ time. Ah, that was a collegiate equivalent of a soulful tearjerker but covered mostly basics she learnt in other classes. Application deadlines are half a year away, so there is ample room for a second lecture. Cool! The plot thickened pretty fast. Her college and graduate school debts are still badly in arrears. Can she be certain that she truly understands everything without attempting an unseen problem? Fetch homework sets from the official homepage tomorrow. Had she been bolder in imagination, she would have gotten question 7 right. Try harder for lecture three’s assignments. She has run out of eligible guarantors for a third loan. Lecture 11. Course completed. What a satisfying visual feast! Hey, the blurb of the follow-up course sounds fascinating too. It is not that she does not love investment banking. How about challenging herself at that course while the material of this course is still fresh in her mind? It is that she loathes investment banking. Mathematical logic has trumped economic logic. 

  How do you hold every number up to infinity in the palm of your hand without a poetic soul? Scoop out a round piece of dough and fancy being able to spread it so thin that it stretches to infinity. But instead of actually spreading it, roll up the edge to form a sphere. Let the bottom tip represent zero and the top tip represent infinity. As a point on the surface moves up from the bottom, it can have components that are each positive or negative, real or imaginary, depending on which pairs of opposite longitudes you assign the real number line and imaginary number line (recall: e.g. …, -10i, -9.99i, … , 0, … , 9.99i, 10i, …, where i is the square root of -1) to. The rise in value of each component accelerates with height, such that the physical gap representing any given numerical difference shrinks infinitely on the surface of the sphere as infinity approaches, making it harder and harder to advance and actually reach infinity. You are now cradling a physical version of the Riemann sphere.

© Jean-Christophe BENOIST, modified under the permission of CC BY-SA 3.0. P(A), around 1.5 in value, on the sphere corresponds to A on the grid, which represents the same numerical system in a typical boundless, regularly spaced 2D format. Similarly, P(B), around -0.5 in value, on the sphere corresponds to B on the grid.

 The macrocosm of universal random structures, infinite products, manifolds and many more is a dearly missed oracle that reveals her inadequacies for what they are, without miserliness, patronizing sugar-coating, or, ironically, calculation: her inflexibility, her inattentiveness, her impatience and her indolence. “Shortcuts and cookie-cutter approaches cannot be your default,” it states plainly. So long as they do not cross a certain line, tactful hypocrites, on the whole, seem to be treated better by their surrounding adult peers than sharp-tongued, straight-talking observers with pure intentions in her circle. Yet the more she experiences of the grown-up world, with the heightened stakes and heightened awareness of interpersonal dangers that deter verbalization of contrarian opinions on the one hand and massive clots of intractable ills on the other, the more she wishes to cherish many of those straight talkers. The ideal living beings are, of course, the severely scarce breed who efficiently marry the circumspection, civility and altruistic strategizing that come with tact with the determination to convey, where necessary, uncomfortable truths. 

For all its uninhibited criticism, mathematics gives credit where it is due and those who converse with it are frequently safe in the knowledge that it means its flattery. It reassures this corporate internee who feels increasingly stuck in her ways that she still has what it takes to master new grammars and vocabularies. It rewards her finesse at plugging gaps in background knowledge by improvising from scratch techniques taught only in later, simpler courses. What if these skills could let her pivot directly to some sector slightly less lucrative but also less odious to her than investment banking, never mind exactly how competitively relevant her prior higher education and corporate experience are?

Far more certain is that her deliciously madcap approach to this discipline with a matchingly rebellious streak has magically quietened the rock concerts and the intoxicated fairy tales and almost erased the jail bars. Nonetheless, as the faded bars unveil more and more vistas stretching beyond the horizons, she starts to wonder if she will live long enough to look a little further, if she will ever squirrel away enough bucks—after all those deductions for debt payments, taxes, food, rent, basic maintenance and transport—to hike a little closer, and if her wrinkled, financially secure self will continue to have the visual and cognitive acuities to deconstruct or even remember the sights a little longer. The jail bars resolidify to some degree.

Still, if positive infinity and negative infinity have been rendezvousing in a dimension invisible until intrepid mind adventurers outed them, and if functions as diverse as trigonometric functions, inverse polynomials and logarithmic functions share the same class of undercover identities, i.e. infinite sums of terms with increasing powers, maybe, she thinks, escape hatches exist somewhere nearby after all.

There may be such a woman. There may be such a snowless ending by a grilled window.

Note: This work of fiction commemorating Pi Day was inspired by an old Dramabeans guest post campaign, a few heartfelt entries of which have appeared in the admin’s Twitter feed. There is no intention, however, to establish any kind of association with the site. Interested readers can find slightly similar math-life themes in the book versions of Kim Ji-young, Born 1982 (82년생 김지영) and The Devotion of Suspect X (容疑者Xの献身).

Bought a pie for work today, forgot the pie at home, now I have a whole pie at home and I don’t know if it’s a good thing or a bad thing

It’s Pi Day!

Pi Day, the informal holiday beloved by math enthusiasts — and even by the math averse — is here! March 14 marks the yearly celebration of the mathematical constant π (pi).

What is Pi?

Pi (3.1415….) is the ratio of circumference to diameter in a circle. Any time you want to find out the distance around a circle when you have the distance across it, you will need this formula.

Despite its frequent appearance in math and science, you can’t write pi as a simple fraction or calculate it by dividing two integers. For this reason, pi is said to be “irrational.” Pi’s digits extend infinitely and without any pattern, adding to its intrigue and mystery.

How Do We Use Pi at NASA?

Measurements: Pi can be used to make measurements – like perimeter, area and volume. 

For example, sometimes we use lasers to explode ice samples and study their composition. In this scenario, we can uses pi to calculate the width of the laser beam, which in turn can be used to calculate the amount of energy, or fluence, that hits the ice sample. A larger fluence equals a bigger explosion in the ice.

Commanding Rovers: Pi is also used every day commanding rovers on the Red Planet. Everything from taking images, turning the wheels, driving around, operating the robotic arm and even talking to Earth!
