[@verizonextron]

and yes, these stickperson are called stickmans, all of them

[@codex2345]

One of my favorite parts was when Euler got the intergral. It was made using limits when the stickman fired the function. It went from 0-infinity.

[@LucenProject]

26:11 He manipulates exiPi by covering up part of Pi so it reads "exit" he's looking for an exit. The thing moving at the end is aleph

[@loganshaw4527]

Odd question. was playing a idle exponential game and I saw something that did not equal what it said it did. Or it did while using the higher dimension you talked about. It look like x log i arrow to the left x log i + x log i-1^dt But the math did xlog0=x and xlog1, xlog2 , xlog3 ,log4 where the only difference was times time So xlog•t=xlog1, xlog•t•t=xlog2, xlog•t•t•t=xlog3, xlog•t•t•t•t=xlog4 I say that because there was a dt that added to make t but if it was 1^d•t and not 1dt it makes alot more sense. Do the professors repeat like that? But have different meanings.

[@HaliPuppeh]

The reason that zeroes were appearing in the first swordfight between Euler and Stickman was because Euler had a -1 and Stickman had a +1. -1+1=0, so every time their "swords" clashed, it made a zero.

[@irrelevant_noob]

@@lukaskamin755 The only Hebrew letter *_commonly_* used in mathematics is aleph, א, (used with subscripts to denote the cardinality of various infinite sets.) -- other Hebrew letters are much rarer, likely just one of the next three letters: beth (ב), gimel (ג), or dalet (ד).

A lot of reactors don't really pick this up, but when they were adding 1 to the power at 7:43, the animation is illustrating it by changing its dimensional visualization. So when they go up to 5th dimension, all the 1s are making giant 1s that add together in a 5th dimensional array.

the ending: the stickman was looking for a way out. e, ×, i and then the first half of π, altogether look like the word "exit" edit: stop liking this

[@SebastianWeinberg]

Yeah, the way I interpreted that scene was that Orange wanted to leave the world of maths and go back to his own world. He thought Euler could help him, because he repeatedly saw him open gateways, using his _i._ But Euler showed him that this gate only leads into the 90° rotated imaginary realm, which is still part of the mathematical world, which is why Orange was downhearted for a moment. But Euler does _something_ multi-dimensional, which I could no longer follow, symbolised by circles in all thinkable orientations forming around Orange. As the number of dimensions trended towards infinity, Orange somehow transcended the mathematical world and was transported out.

[@gswcooper7162]

At the end, Stickman was asking Euler to help him find a way out of mathspace - he was looking for an EXIT (e x i, and half of pi is visible). I think Euler then created the formula for the volume of an n-dimensional hypersphere to use as a portal to send Stickman back to his own reality. At the very end, the difficult-to-see giant in the background was Aleph-null. :)

[@aimsmathmatrix]

Such a neat touch! I think Euler calculated the volume of a unit ball in n-dimensions in the limit, which would actually approach 0 given the formula. For general banach space unit balls, it's a bit different (I believe since for L^p spaces, it is), but regardless, nice touch with the infinite dimensional portal, lol.

It's mildly upsetting to me that only now, in my middle years, that I find maths this fascinating. Whereas, as a youth, maths was such a huge disappointment and I was turned off it.

13:50 Their hilts. "e" has - and "The Second Coming" (yes, that's his name) has +. That's why when they both have 1 blades they result in 0. 22:56 "The Second Coming" shoots with infinity and e catches it with integral. 27:40 That symbol is Aleph. It's so big because it's the smallest infinity.

[@Sagitarria]

My take on the sudden appearance of Eulers identity is that it’s kind of inherent in what’s so strange about negative numbers to begin with. When people first started accepting negative numbers, there’s this whole quality of mystery which already takes you off the map of things that you can count in real life

[@Dominodude55]

Which is crazy to me, because I understood negatives numbers at like the earliest ages, since I'm Canadian and the temperature went below zero every winter. Honestly I knew about negative numbers before I knew about multiplication.

@@Dominodude55 negative numbers were not in use in European mathematics until the 1700s around the time of the invention of modern ideas of debt and the idea of a temperature scale. These are all new ideas. Euler’s identity shows up around the same time in 1748

[@Sagitarria]

Until then no one grew up with any of this.

[@samgordon9756]

If no one else has explained, this orange stick figure is a protagonist or deutero-protagonist of several videos and shorts. He's known as The Second Coming (TSC) for... reasons. If TSC can be said to have a particular power, it's that he learns extremely fast. He also seems to be a gifted martial artist, but that's possibly something he picked up in passing. Most content involving TSC is meme style humor, with a few longer form story vids. Animation vs. Math and the follow up Animation vs. Physics are most similar to each other.

As someone who is NOT a mathematician, hearing the phrase "Oh are we moving into another dimension? Oh four? The fourth dimension? So surely time's gonna play a big part in this" broke my brain a bit.

[@patrickhector]

You can describe our universe in three spatial dimensions (length, width, height) and one temporal dimension (literally just a point in time), which is why she assumed going into four dimensions would lead to some exploration of time. But, this is pure maths, and that goes more into the realm of physics - the next video after this is called animation vs. physics though and definitely worth a watch!

[@The_Ibsy]

Nice reaction lmao, this animation has inspired me in so many ways and I was NOT expecting a channel about silly Minecraft and Stickman animations to make such a cool animation for the maths community on YT to enjoy. Some stuff I wanted to quickly mention: -19:55 Nah the dot operator is just referring to "nothing" here, basically the arrow was just above the animation was just tryna show he simplified it heavily into by saying 'tan is just a function (at the end of the day)' -26:09 Euler's identity was spelling out "exit" here -The stickman's name is "The second coming" and is an important character from Alan Becker's other animations and he's just trying to go home (which is Alan's - the maker of these animations - desktop loool)

[@samsamson3315]

A few points: - At 16:00 they were showing that the arc of 1 radian on the unit circle has a length of 1. - At 19:06 the stick person uses a minus sign to flip sides - At 24:50 the "imaginary world" is rotated 90 degrees, presumably because multiplying by i rotates 90 degrees. - At 26:50 it's playing on the fact that the (hyper)volume of an n-ball is pi^(n/2) / Gamma(n / 2 + 1);

[@Keiko.IsDestined]

"this is a very agressive stick person" is the perfect way to describe TSC, especially when his friends are in danger i dont know if you know it already, but the stickmans name is The Second Coming or just Seccond for short, and hes a character from Alan Beckers chanel where he has his own series "animation vs animator" and "animation vs minecraft" and they both have insane lore and story, that some people even cried at few of the episodes! (including me)

[@asilbekashirov1341]

26:12 the stickman was trying to explain the "exit" word. Euler constant is "e" letter, multiplication is "x", imaginary number is "i" and half of pi letter is "t", so you can read "exit" word. At the end e^(i*pi) built a kinda portal for stickman. And -1 at the end means stickman has disappeared from that world.

[@meme9492]

8:27 -- The game she's referring to is 2048.

[@danixghozt7568]

So when Euler was "fencing" with stick man, Euler had a -1 sword and the stick man had a +1 sword. When they clash they cancel to 0, which is why there were flashes of zeroes. And when Euler has upgraded his -1 sword to -4, the stick man's +1 sword "broke" because -4 is greater than +1 but it has reduced the -4 into -3 due to +1 clash. At 14:00

[@LazerDude]

I love how she knows all these complex math equations that my mind can't even comprehend and didn't get that he was asking for the Exit

[@xuananhcao8744]

Its probably tunnel vision, the whole vid was abt math so her mind is completely fixated on math at that point so she was thinking of a formula/equation, ignoring the obvious wordplay

[@thekid317]

some lor, stickman is a creature living in the PC of Alan becker, and many times he enters apps and stuck on them not finding the exit back like what happened with minecraft, this time he enters the calculater and this is how the video started, and that's why he was so agressive because he want out, so at the end he was asking the e for exit and he even wrote it with ×eit. however moving him through the higher dimentions of the Gama function didn't let him out but it sent him to Animation VS Physics which you should watch too.

[@Artimis.depressed]

The way you remember your 2^n tables at 8:51 is really cool, i'm a computer scientist so i just remember them by taking 8^n and dividing by 4

[@thisisrealaye]

23:38 this is actually clever, since the stickman combines cos and isin to create the euler formula, which then turns other eulers into 0

[@scytube]

19:46 "I feel like to watch this you need to know quite a bit of maths" Yeah that's why simple computer scientists like me watch reaction videos from actual mathematicians to at least get _some_ idea of what's going on 😂

[@saiyanshinobu5509]

20:52 The reason why 0s are appearing is because of the multiple e^iπ's getting hit from the bullets and turning into 0. TSC (aka "The Second Coming"/Orange Stickman) created the function 9tan(πx). When you replace x with e^iπ, it results in tan(-π), which in radians is 0! Really clever!

[@williejohnson5172]

Finally. Someone gets it. As beautiful as Euler's identity may be it is Euler's formula which encapsulates the whole mathematics. (or at least most of it) Notice at 20:15 how he creates calculus from the sin and cos creating the tan which becomes the f of dot which is the dot notation for a derivative. Calculus is nothing but trig and trig is nothing but Euler's formula. This is why earlier when he tosses the dot in the air he forms the iy axis thus y=f'(x). Lastly notice how he forms all the higher dimensions from Eulers formula creating complex numbers to quaternions (-cos+isin) to higher dimensions. This guy Becker knows his stuff. An outstanding achievement.

I've always had a love for the law of cosines and also it's relation to the dot product of vectors. Dot products are easy to calculate, but embedded in there is a bunch of information that can be pulled out with the law of cosines.

[@HexanTronic]

There is in fact a continuation to this, after Stickman/Orange/The Second Coming gets sent away, he appears in another numbers based realm, one focused on Physics this time. So Animation vs Physics. It's an amazing watch and I'd recommend checking it out.

[@jamesherrensmith7887]

The giant letter at the end you were asking about is the Hebrew ALEPH. In mathematics, particularly in set theory, the aleph numbers are a sequence of numbers used to represent the cardinality of infinite sets that can be well-ordered.

8:11 2048 is a fun and interesting game, but it takes FOREVER to actually complete the game (maximize) I have yet to approach the biggest tile in 4x4. *I still play it sometimes.

[@circuitcraft2399]

By the way, the stickman's name is TSC (The Second Coming), or just Orange. The reasons for the first name are intertwined with the lore (yes, there's lore) of Becker's world. Watch the first few Animator vs Animation videos (1 through 4 at least)!

The zeros were showing that the clashes of weapons (which were expressions) when added to eachother (clashed together) would equal 0. Example: the first time you saw them, it was a clash of +1 and -1. The odd symbol in the background at the end was a Greek symbol called “aleph” and the reason it was blurred is because aleph null (aka. aleph zero) (the aleph character followed by a subscript 0) is the theoretical highest real number in a sequence of all real numbers counting starting at 0, 1, 2, … It is faded to the background because it is theoretical. (aleph one would be aleph null + aleph null and so on)

Mathematics is the power of Human imagination. Imagination must be a universal language. The universe would have to be conscious to imagine.

[@Egon_Freeman]

I remember back in ground school how I had trouble understanding why you can't divide by 0... The explanation that finally made me "get it" was basically: "Well, if you divide a non-zero A by B, you get C... but if you divide A by 0 to get C, there is no such C where C × 0 = A".

Alan Becker is just a famous animator/channel in general, and this was probably the video of his that exploded the most fiercely.

[@reminderIknows]

20:38 f(x) = 9tan(pix) tan(pix) = 0 9tan(pix) = 9 * 0, which is just 0 so f(e^(i*pi)) = 0 which becomes a gun that when substituing e^(i * pi), the 'eulers' become 0, effectively cancelling them

[@Pangerg]

26:08 The Stickman wants to find an exit to get back to his world and he spelled "exit" (t was made by covering half of the π) 27:18 e^(iπ) helped the stickman escape and return to his world. The stickman's actual name is "The Second Coming" (TSC for short). He's from a series where he and other stickmen, which are his friends, get in some crazy adventures (minecraft adventures being the most popular).

[@Benoit-Pierre]

17:47 about agressive : you didnt understand the deep origins of this history : animation vs animator ... Agressive is the heart of this lore.

[@thesuitablecommand]

26:10 - ya know, ive watched this animation several times. I never realized what was going on in this part until just now - TSC is trying to spell "exit" using math symbols. e, x, i, and part of pi. Clever. The more you watch this, the more you notice.

[@thesuitablecommand]

Bit late on this, but the stickman's proper name is "The Second Coming" (TSC) according to the lore of the creator. The integral bit was my favorite piece of the video. Using the definition of an integral as the sum of an infinite series of infinitely small pieces to protect e from TSC's f(•)= attack was a funny and well-done illustration of how integrals work.

[@skilz8098]

The big symbol in the background is the hebrew character for Aleph. It is also used in higher levels of mathematics within number, and group theory.

[@rockcitygamer12]

U missed the infinity was stopped by the limit integral sword

[@moriskehl5991]

27:40 that thing in the nackground is the aleph symbol i think

[@Studio_salesmen]

2:27 has to be the greatest team up of all time, completely unexpected and amazing.

[@fluffezic5183]

also. i love how the bow the stickman (technically called "the second coming") uses shoots 4s. because its made out of a 2. another 2 a X and a =. also. the reason why the transformer used the integral as a staff is because he blocked the stickmans function beam and turned it into an integral.

[@Cyrus_T_Laserpunch]

When they're fighting with swords, the zeroes appear because the stick figure is fighting with a +1 and the Euler formula is using a -1, the arrows are 4 because his bow is made of the equation 2x2.

[@thefactspherefromportal2740]

23:04 love how the integral staff attacks in circular motions!

[@SaschaKersken]

Fun fact: The game with the 2^n tiles is called 2048, but I used to call it 1024 too because that was typically how far I got before filling up all the space.

[@lory24bit]

Stickman was searching for an exit, Euler's identity made him a makeshift multidimensional teleportation series. The big thing in the background is Aleph (first letter of the Jewish alphabet)null, the smallest infinity (all natural numbers). Check "Counting past infinity" by Vsause

[@braydonfisher9273]

Euler's formula at 12:49 is incorrect. e^(i*pi) is equal to cos(pi)+i*sin(pi), so -e^(i*pi) equals -cos(pi)-i*sin(pi), the minus sign in front of i*sin is missing

[@Murrlin27]

I've never seen an Alan Becker animation analyzed until now! Superb!!

[@AmaroqStarwind]

The orange stick figure with the hollow head is TSC (The Second Coming). Just a bit of Alan Becker "Animation vs. Animator" lore.
