Unlocking the Wonders: 35 Fun Facts about Geometry

The spirit of genuine mathematics, i.e., its methods, concepts, and structure – in contrast with mindless calculations constitutes one of the finest expressions of the human spirit. The great areas of mathematics – algebra, number theory, combinatorics, real and complex analysis, topology, geometry, trigonometry, etc. – have arisen from man’s experience of the world that the infinite, personal,…

In which I describe the maths of how to attack and dethrone God (per Minamimoto)

So in my evergrowing post thread (which I know I'm already gonna have to add to that essay fml) I did make ref to...well, a thing that literally has made my jaw drop since when I played TWEWY the first time (and keeping in mind this was a game friends forcefully insisted I play because "there's a char Sho Minamimoto who's just like you fr", and after I'd nodded "yup" re the SI unit obsessions and the compsci refs to Heaps and Crunching (and later, as I found out, "crashing" in JP), and the aesthetic, and, and...)

Namely: Sho Minamimoto literally uses (or tries to use) a very famous maths formula called Euler's Identity to take out the Composer as an example of Forcefully Applied Mathematics. :D (This may have also been the moment when I was like "Yup, he just like me FR")

So. First off. Euler's Identity.

It's kind of difficult to explain why this particular equation is considered one of the true Chef's Kisses of Mathematics to non-mathematicians, but part of it is elegance, and part of it is that it includes five of the foundational variables that show up in mathematics all the time (and really even more functions if you break it apart): a) the natural logarithm e or Euler's number which is roughly 2.71828182845... and which is zetta important in a lot of fields including finance, biology, medicine, and calculus functions, and (as we'll get into) antennas and field strength measurements and pretty much a Shitload of functions related to growth b) the imaginary unit i or the square root of -1 (which turns out to be extremely useful in a lot of contexts, including electronics (seriously; AC electricity and functions relating to that are *heavily* dependent on the imaginary unit) and graphing and arguably how Cartesian graphs work especially once you get into calculus c) Pi (π), everyone's favourite circle ratio of 3.141592653589793238462643393279 (is pulled away from keyboard before I can draw a Taboo Noise Refinery Sigil in Paint) and which is Important in many, many contexts d) 1 (yes, 1 is considered a constant! Specifically "A quantity exists") , and

e) 0 (yes, 0 is considered a constant too, specifically "a quantity does not exist", and reducing Euler's Identity results in e^(i*pi)+1=0) To make it even more Minamimoto-esque, you can technically also express Euler's Identity as a reduction of "e^(i*x) = cos(pi) + (i * (sin(pi)) (aka Euler's Formula), and cos(pi) =-1 and sin(pi)=0.

And really it's kind of a beautiful way of how things all fit together in a lovely function that is almost a kiss from the Math Gods and if plotted traces a lovely circle.

So after that little tangent, here's how this all relates to W2D7 of TWEWY, and Minamimoto's forcefully applied mathematics. * * * So, first we end up at Pork City (Mark City if you're watching the anime; Tokyu Group liked the TWEWY tourism and by the time the anime and NEO came around decided to take advantage of the advertising), and...Joshua and Neku start having a very interesting conversation on why there's So Much Damn Noise at Pork City anyways:

Neku asks if this is the work of Pi-Face, Joshua notes "Probably" and then goes on to note that it might not all be JUST Minamimoto:

In other words: Pork City is effectively acting as an amplifier or at least an antenna for Noise. (I am not the only one to have noticed it and not even the only one on Tunglr, for that matter; Voice From The Corner also picked up on this as well though I'll freely admit I'm diving a bit more into the STEM portions of this.) TWEWY:tA is even more blatant about this imagery in ep 6, where Joshua explicitly notes that all the emotion in Shibuya collects at Mark City (remember, the animation uses the RL name) and then "crashes into Mark City and shoots up into the sky. That emotion flows back down and keeps building up here." (Shortly afterwards, Joshua also mentions the Imaginary Noise Plane as the inside of Mark City warps, similarly to a sine wave flow--or the flow of energy into, or out of, an antenna. (You do not know how loudly I screamed seeing this, as an aside) So, this is where we get into piece one, e (and where a healthy interest in radio and electronics hobbies helps!)

So antennas, interestingly, have how well they pick up a frequency measured in a logarithmic scale, and basic field strength measurements (and a lot of other "wavey" things, including earthquakes, including, well, literal background noise) get measured on logarithmic scales too. It's rather more common with antennas and earthquakes for this to be measured on log-10 scales (hence the Richter scale for quakes, or decibels for antennas and sound). There's a particular group of measurements (physical field and power measurements), however, that actually uses log-e, aka the natural logarithm, and especially for voltage or current and "root power quantities"--the neper. And, in Euler's Identity, e is taken to powers...and Pork City is basically acting as a huge antenna. Also in info engineering aspects, there's another aspect--the nat, which is considered a unit of information or info entropy...also based on e. (I told you Euler's number comes up a lot of places!)

Let's continue... So now we come to i, the imaginary unit, and that's called out blatantly by Joshua:

This, too, is based on math--from Final Fantasy II, specifically, and how the Flare spell worked. Flare is an area-effect spell and it hit based on (Enemy's HP/Flare level), i.e. enemies that had HP divisible by 2 could be hit by a Flare level 2 spell and could deliver damage based on that spell's level, etc. So a level i Flare, based on how complex numbers work, could hit just about anything (assuming, of course, that the Composer is not a Fractal Bastard and promptly yeets himself into a PokeYugiBeyBladeVerse). But...that's not the ONLY part where things imaginary come into play. So, one of the interesting bits of lore that came out in (of all things) the NEO:TWEWY Field Walk RPG (alas, JP only, but a delightful source of lore, and thankfully the fan community preserved almost all of it) is actual canon on how Tin Pins and Psychs work including the actual formula on how they work in a convo between Minamimoto and Fret:

Fret: Soooo, these psychs and pins and stuff… how does it all work? Minamimoto: The pin is charged by the Imagination of the user. Fret: Uh huuuh. Minamimoto: The pin itself is just a medium. Fret: Mm-hmm. Minamimoto: “Power” is calculated from the numerical limit of the pin, using your will as a coefficient. Fret: Yeah. Minamimoto: But that formula alone means nothing to me!

(Emphasis mine: props to Pavaal on the Dead Bird App for initial translation, and to multiple others for confirmation from the FWRPG script.) So basically how Psychs work is functionally as an athame, using formula Psych=Limit^Imaginatio. (Secret Report 1 in TWEWY also confirms Imagination is important in making a Psych work to begin with; the formula) Of note, Minamimoto also has a canonically high Imagination, as detailed in the Secret Reports. To even become a Reaper to begin with (as noted in SR7) those who survive the week who have enough Imagination become Reapers, and even among Reapers Minamimoto tends to stand out (he is canonically the youngest Reaper Officer ever, and apparently had quite the rapid rise to power). SR15 in TWEWY notes (even keeping in mind that in this instance Hanekoma is being a bit of an Unreliable Narrator in covering his own butt regarding the Taboo Thing):

The sigil Minamimoto drew was one of the undecodable types. Was that a mistake on the Fallen Angel's part? Or was it a transcription error by Minamimoto? Either way, with that design, he stands little chance of reviving himself. However, Minamimoto is driven, and his Imagination strong. Perhaps strong enough to make a Taboo sigil work, even in the Underground... If so, the specific result would be impossible to predict.

And in SR19 (again, covering up just a bit for his own helping hand):

I've detected an energy spike here. It would seem Minamimoto has returned. I judged his revival unlikely after spotting his Taboo refinery sigil on the first day, but it appears Minamimoto's Imagination is much stronger than I'd anticipated. The Fallen Angel must have completed the array for him. A troubling thought. Who can say what impact this will have on the Composer and Conductor's Game?

And even in the NEO Secret Reports it's noted his second trip through Coco's version of the Sigil actually ramped up his Imagination even more (in NEO SR 7):

Minamimoto, on the other hand has all but vanished from the proxy’s side. His Noise refinery sigil drastically heightens his Imagination, which may be why he can clearly recognize the proxy’s abilities. I have an idea of what he’s planning. It’s dangerous, but I have no way of stopping him.

And again, TWEWY:tA also makes it more blunt that Minamimoto was selected explicitly because of his Imagination and his connections to Shibuya as Hanekoma's Plan B. So there's imaginary units (in the sense of literal level i flare), and imaginary units (in a Reaper whose Imagination is already in the stratosphere). And in regards to pi? Well, Pi-Face, he has very much a rep of being....numbers- and math-obsessed even BEFORE he throws 156 digits of pi in the Composer's face:

But pi (as a number) is actually meaningful as HELL to Minamimoto, he engages in saying pi to himself drawing the Taboo Noise Refinery Sigil (goroawase in Japanese which relates to literally an obstetrician going to a foreign country and a woman giving birth at night as insects make a lot of noise which can almost be seen as a minor ritual to Make It Work, a little happy pi rhythmic thing in English in the game, actual spoopy sounding pimetry in the anime that sounds very sorcery-y). Looking (for far too long) at the Taboo Noise Refinery Sigil, pi is encoded in it in at least four or five places (multiple times as functionally a magic binding circle, at least once where he draws the symbol for pi in such a way that when it's turned upside down it literally spells "pi"). It's important. It's meaningful. It's His Number and transcedential and irrational and beautiful and unrestrained :D So now y'all are wondering, "OK, smartass, where's the -1 at?" As I noted, another way you can write Euler's Identity is specifically as "e^(i*pi)+1=0", so that can be expressed as a way to null the Composer (who is probably the 1 in question). Euler's Identity would be used to subtract 1 from the equation, in other words (as Minamimoto was intending to come back from Erasure by literally integrating himself via Taboo Noise Refinery Sigil). There's one other interesting bit of symbolism, one that's deep enough that I'm not even sure the writers of TWEWY intended, but if so...it's such a chef's kiss that I have deepest admiration.

So Euler's Identity can be expressed in terms of a formula, and as a reduction of sine and cosines involving pi and i, but it can also be mapped as motion--specifically as how a function evolves. (I tend to be a pretty visual thinker, and there's an extremely good discussion on Euler's Identity here that goes into the whole "mapping the function" aspect to show how Euler's Identity works in practice.)

So typically when you're doing a non-negative function or a zero function, generally there's an assumption of "right-hand" rotation or movement. Complex functions, you get into fun things like circles, and curves, and even some very beautiful fractals (like with the Mandelbrot set) with the right iterative formulas. Euler's Identity...is literally a left-hand-path function:

(And those of you who were writing about the Cyclic Nature of Minamimoto are probably all screaming right now) Anyways, wanted to share in full one of the things that was a jawdropper for me in TWEWY back when I found the game at a glorified skateshop that sold games in 2011. Thank you for coming to my TED talk, zeptograms :3

[galaxyharlot]

Having a day and need to distract myself so I'm going to over analyze a throw-away line from Speed Racer 2008. Any mention of Speed Racer in this essay is in regards to that movie.

Before reading this understand that Speed Racer is a movie about macro economics effecting the individual. Any science talk is just flavor to that, and studies like this take a lot of liberty.

"Pops. Thats a Bernoulli Converginator!" "Transponder Shmonder. You want real kick you go Bernoulli."

What the fuck is a Bernoulli Converginator and why is it a big deal.

Now. First assumption. Bernoulli is a companly like Edison Motors or Tesla. Named after someone famous in the history of physics and electronics and speed.

I'm watching a video about Spider-Man 2, and how to make a good sequel. https://www.youtube.com/watch?v=lCVYDrtecDY

In it we hear Doc Ock talking to Peter about Bernoulli, and Peter asks "Did Bernoulli sleep before he found the curves of quickest descent?"

I'm going to assume that this was a well researched line, because Spider-Man 2 tries to be at least somewhat accurate with its real world physics, I think.

Looking it up, the Bernoulli family lineage has a lot of mathematics in it. Daniel Bernoulli is who we're talking about in regards to Speed Racer, for sure. His findings lead to the invention of the carburetor.

Sidebar: He was friends with Euler. I wonder if Speed Racer Universe has a company called Euler. They created a theory that explained how steel can bend without cracking. The racing cars in Speed Racer, the T-180, are essentially jets with wheels. They don't turn the wheel to turn the wheels. They turn the wheel to turn the engine.

Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or the fluid's potential energy

Another sidebar, apparently Mach is the measure of how fluids relate to the Bernoulli Principle. No clue what that relationship is. From what I can garner, it has to do with the idea that going faster fucks with the pressure of air impacting the thing going fast.

Actually, I don't think thats a sidebar. I think that can lead to the answer of "what the hell is a Bernoulli Converginator". We have an answer to what the Bernoulli half is now. Its short for Bernoulli's Principle, which has to do with Mach speeds and how they influence the pressure around something going fast.

That leads to the next question, what is a converginator? Converginator as far as I can tell is something that the Speed Racer movie came up with. So, lets break it into its principle parts. Converginate and "or". "Or" is usually a suffix that means "something that does the thing being modified". Convergence is the act of unifying, in multiple definitions. So, this is a device that unifies bernoulli's principle.

What the heck does that mean. We know that it makes things go fast, and its a power supply, and it has kick. Another throw away line with lots of weight becomes important here.

Actually, rolling back a bit first. Some more bits about the converginator. When they get the Mach 6 Car going, it starts up sounding like a V12 Engine. Or as Speed puts it, "Sounds beefy Pops."

So something about it has something similar to gearing. The design of it reflects that too. It looks like a scifi version of 6 piston engine. T-180s are all electric. So what the heck is making that noise? For right now, I'm going to either assume magnets or something causing a lot of increase or decrease to pressure.

Might be important to talk about why they're using a Converginator. The finale of the movie showcases the battle between new technology optimized by a company, and a dedicated practice working with the tools they know for the customer they know. The company they're up against created a car that uses something called the Transponder. I'm going to ignore that for now, or until this essay decides its suddenly relevant. What we need to focus on now is how a Bernoulli Converginator works to Speed's abilities and knowledge.

Now, onto that important throw away line. Speed spins out, and his car stalls, and these races don't do pit crews. He has to figure out how to get it running again, and he can only rely on the foresight of Pop's designing, and his own knowledge of that design. That foresight leads to him remembering that he can jumpstart the car with the Bernoulli Converginator. So, this thing has to be making power somehow. Either that, or its messing with potential energy.

The fluid in this case is probably air, given that aerodynamics is important. This thing can turn air pressure into electricity. Thats pretty damn cool. It reduces the pressure of the air around the car, and turns that pressure into electricity. Converting that air's potential energy into kinetic energy. This lines up with the movie I think, cause when Speed does that, he fuckin zooms. Cars don't just magically go faster than their top speed. This guy didn't just jumpstart his car. He made a mario panel speed boost to the finish line with an expert supermove that only the bernoulli converginator can do.

How to Identify an Irrational Number? 

An irrational number is a real number that cannot be expressed as a ratio of two integers. In simpler terms, it cannot be written in the form p/q, where p and q are integers, and q is not equal to zero. The decimal representation of an irrational number neither terminates nor repeats. It continues indefinitely without showing any discernible pattern.  

Properties of Irrational Numbers  

Infinite Non-Repeating Decimal Expansions: The most defining characteristic of irrational numbers is their decimal expansion. Unlike rational numbers, which have either terminated or repeating decimal expansions, irrational numbers continue endlessly without exhibiting any recurring sequence of digits.  

Non-Expressible as Fractions: Irrational numbers cannot be precisely represented as fractions. This is because their decimal expansions are infinite and non-repeating, making it impossible to find two integers that can accurately capture their value.  

Real Numbers: Irrational numbers belong to the set of real numbers, which encompasses all numbers on the number line, including both rational and irrational numbers.  

How to Identify an Irrational Number?  

To identify an irrational number, you can look for the following characteristics:  

Infinite Non-Repeating Decimal Expansion: If the decimal expansion of a number goes on forever without repeating, it is likely an irrational number.  

Non-Expressible as a Fraction: If a number cannot be written as a simple fraction, it is an irrational number.  

Square Roots of Non-Perfect Squares: Square roots of non-perfect square numbers are often irrational. For example, √2, √3, √5, etc., are irrational. 

Famous Examples of Irrational Numbers  

The Square Root of 2 (√2): This is perhaps one of the most famous irrational numbers. It represents the length of the diagonal of a square with sides of length 1 unit. Its decimal expansion begins as 1.41421356… and continues infinitely without repeating.  

Pi (π): Pi is another well-known irrational number, representing the ratio of a circle’s circumference to its diameter. Its decimal expansion starts as 3.14159265… and extends infinitely without repeating.  

The Golden Ratio (φ): Often denoted by the Greek letter phi, the golden ratio is an irrational number approximately equal to 1.6180339887… It appears frequently in nature, art, and architecture.  

Euler’s Number (e): Euler’s number is a mathematical constant approximately equal to 2.718281828459… It plays a crucial role in calculus and other areas of mathematics.  

Why are Irrational Numbers Important in Mathematics?  

Irrational numbers play a crucial role in various mathematical concepts and applications:  

Geometry: Irrational numbers are fundamental in geometry, particularly in calculations involving circles, triangles, and other geometric shapes.  

Physics: Many physical phenomena, such as the motion of planets and the behaviour of waves, involve irrational numbers.  

Engineering: Engineers use irrational numbers in designing structures, calculating electrical circuits, and analyzing various physical systems.  

Computer Science: Irrational numbers are used in computer graphics, cryptography, and other areas of computer science.  

The History Behind the Discovery of Irrational Numbers  

The discovery of irrational numbers is often attributed to the ancient Greek mathematician Hippasus of Metapontum. He is believed to have encountered irrational numbers while studying the properties of right-angled triangles. Specifically, he found that the diagonal of a square with a side length of 1 unit is incommensurable with its side, meaning it cannot be expressed as a rational ratio.  

Applications of Irrational Numbers in Real Life  

While irrational numbers may seem abstract, they have practical applications in various fields:  

Construction: Irrational numbers are used in calculating the dimensions of buildings and structures.  

Navigation: GPS systems rely on calculations involving irrational numbers.  

Medicine: Medical imaging techniques often use algorithms that involve irrational numbers.  

Finance: Financial models and calculations frequently incorporate irrational numbers.

Fun Facts About Irrational Numbers  

The decimal expansion of π has been calculated to trillions of digits, but no repeating pattern has been found.  

The golden ratio appears in many natural phenomena, such as the arrangement of leaves on a plant and the spiral patterns of seashells.  

Euler’s number is the base of the natural logarithm and is used in various mathematical and scientific formulas.  

The square root of 2 was one of the first irrational numbers discovered.  

Common Misconceptions About Irrational Numbers  

Irrational numbers are rare: In fact, irrational numbers are far more common than rational numbers on the number line.  

Irrational numbers are difficult to understand: While the concept of irrational numbers may seem complex, they can be understood with basic mathematical knowledge.  

Irrational numbers have no practical applications: As we have seen, irrational numbers have numerous real-world applications.  

Exploring the Relationship Between Pi and Irrational Numbers?  

Pi (π) is one of the most famous irrational numbers. It represents the ratio of a circle’s circumference to its diameter. Its decimal expansion starts as 3.14159265… and extends infinitely without repeating. The irrationality of pi has been proven, and its decimal expansion has been calculated to trillions of digits, but no repeating pattern has been found.  

Irrational Numbers in Geometry  

Irrational numbers play a significant role in geometry, especially in calculations involving circles, triangles, and other geometric shapes. For example, the diagonal of a square with side length 1 is √2, an irrational number. The Pythagorean theorem, which relates the sides of a right triangle, often involves irrational numbers.  

The Infinite Nature of Irrational Numbers Explained  

The infinite nature of irrational numbers means that their decimal expansions never terminate and never repeat. This is because they cannot be expressed as a simple fraction. The digits in their decimal expansions continue indefinitely, without any discernible pattern.  

Challenges in Calculating with Irrational Numbers  

Calculating irrational numbers can be challenging due to their infinite nature. In practice, we often use approximations of irrational numbers to perform calculations. For example, we might use 3.14 as an approximation for π.  

Approximations and Calculations with Irrational Numbers  

When dealing with irrational numbers in calculations, we often use approximations. These approximations can be obtained by truncating or rounding the decimal expansion of the irrational number. For example, we can approximate √2 as 1.414.  

Why Can’t Irrational Numbers be Written as Fractions?  

Irrational numbers cannot be written as fractions because their decimal expansions are infinite and non-repeating. If a number can be expressed as a fraction, its decimal expansion will either terminate or repeat.  

The Role of Irrational Numbers in Advanced Mathematics  

Irrational numbers play a crucial role in advanced mathematics, including calculus, trigonometry, and number theory. They are used in various mathematical concepts, such as limits, derivatives, and integrals.  

How to Teach Students About Irrational Numbers Effectively?  

To teach students about irrational numbers effectively, consider the following strategies:  

Start with the Basics: Begin by explaining the concept of rational numbers and their decimal expansions.  

Introduce Irrational Numbers Gradually: Introduce irrational numbers as numbers that cannot be expressed as simple fractions and have infinite non-repeating decimal expansions.  

Use Visual Aids: Use diagrams, number lines, and geometric shapes to illustrate the concept of irrational numbers.  

Provide Real-World Examples: Discuss real-world applications of irrational numbers to make the concept more relatable.  

Encourage Exploration: Encourage students to explore the properties of irrational numbers and discover patterns and relationships.  

Use Technology: Use calculators and computer software to visualize and calculate irrational numbers.  

Practice, Practice, Practice: Provide students with ample opportunities to practice identifying, comparing, and calculating irrational numbers.  

Irrational numbers, with their infinite and non-repeating decimal expansions, continue to fascinate and challenge mathematicians and enthusiasts alike. From the ancient Greeks to modern-day scientists, these enigmatic numbers have left an indelible mark on the landscape of mathematics.
