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.

17:14 "This is a very aggressive stick person"

The most succinct explanation of Alan Becker's channel. Well done.

[KrishnaPlayz]

27:42 it was aleph, the smallest cardinal infinity, that's why it was so big

[hqppyfeet]

26:09 Here the stickman was looking for an exit, quite hard to spot after an overload of mathematics ahhah.

[isais]

Me, a 32 year old, sitting here and watching a 28min fun video about maths with a smile on my face while knowing full well all context of what I learned in school has been almost completely wiped out of my brain 🥲

[psical]

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

[coldReactive]

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.

So the game you were talking about is called 2048 and yes it was huge a few years back! You unlocked a core memory for me lol

[alexolas]

oh boy, it’s fun to see a proper mathematician recognizing everything (well, most of) in real time. you should also check out becker’s sequel to this, “animation vs physics”. spoiler without spoiling: the hollow orange stickman is about as reckless as he is aggressive

[gerritvalkering]

Euler's number runs away and is 'growling' because it's an irrational number

[gswcooper]

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. :)

[gargitripathi]

Big thing moving in the background at the end: Aleph Null

"Stickman" was looking for an exit to go back to his world

[kdog]

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. Maths was the only subject at school that I actually struggled with. Top sets for everything EXCEPT maths. And yep, it still galls me! 😂

[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

[jedrzejkoszewski]

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.

[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

[samgordon]

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.

[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)

[danixghozt]

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

[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 😂
