[@johncollinowensy4255]

Little addendum for the stuff you missed: - The thing attacking them is a 4D shape. Apparently it’s called a 24-cell. - The Pythagoreas Theorem proof is also a proof for Φ + 1 = Φ². Specifically it said Φ raised to 0 plus Φ raised to 1 equals Φ squared. - That bit makes the golden rectangle, and it pops up later during the pentagram battle. - The dart shape is also part of the rhombic structure associated with the golden ratio, and Phi they did in fact make that shape to protect our stickman. - You probably noticed, but I’ll still mention how the badass Phi army was creating all sorts of Φ shapes and lines to pelt the 24-cell. Absolute masterpiece. - Phi army dropped some golden rectangles earlier, our stickman used them to create vertices that if you connect lines through, traces an icosahedron (it did this without Phi’s help, so proud) - Phi then uses this to connect a dual one with area Φ², to create a bigger set of vertices to create the dodecahedron. - Apparently if you put three dodecahedrons to the same edge you get that mirror effect or something, I honestly don’t understand that higher dimension explanation from the over-analysis either lol. The other shapes there are also the bigger and smaller 4D shapes, including the 600-cell forming a shadow in the mirror plane. Try and look for it, I’m sure you missed it. I did. Several times. - The current crackpot theory is that: Stickman arrives in math dimension > gets Euler’d to geometry dimension > falls off dimensional mirror into physics dimension > creates the entire universe with black hole time travel > Stickman is data and therefore immune to death by spaghettification > ???

i'm hoping they do a atomic chemistry part as continuation of coming out of the black hole area and after that a molecular sized one that explores how different atoms react with each other and form bonds. then either go up the electromagnetic route into engineering or light theory or so(doing more more specific physics unrelated to speed) or into the dna and cell area and up the biology scale.

[@finian2]

The 4D shape is also known as a hypercube. It's a theoretical shape that takes the idea that: a 1D line is made of two 0D points. A 2D square is made of four 1D lines. A 3D cube is made of six 2D squares. If we continue that logic, then a 4D hypercube is made up of a number of 3D cubes.

[@dovos8572]

[@dibenp]

I think the "graph theory blob" is a 24-cell. This four-dimensional shape is difficult to understand because it has no analogue in higher or lesser dimensions. Or as HSM Coxeter states in the epilogue of his book "Regular Polytopes", the 24-cell is a shape that "stands quite alone". So as a story, perhaps the 24-cell was lonely, misunderstood, wanting friends. By the end of the video, TSC and phi have worked together to reunite the 24-cell with the other 5 convex regular polytopes, as a family. Very on brand for Alan's stick-o-verse.

[@connortg5]

that would be fitting for alan's animations, but they make it pretty clear when the plan is explained that the goal is to destroy the 24-cell, not just to trap or calm it down

[@maddreax]

I think someone else mentioned it elsewhere, but the big evil thing is a 4D shape, specifically a 24-cell. It's amazing how they used a 3D shape to trap a 4D being on a 2D plane.

[@wanwan_anderson]

Since TSC and phi are trapped in a 1D line, it would make sense to trap a 4D thing in a 3D shape.

[@nanamacapagal8342]

​@@wanwan_anderson therefore implying that the 4d thing isn't exactly flying, gravity is just affecting it in the 4th dimension

[@SgtSupaman]

A 3D shape cannot trap a 4D being, because it can move on an additional dimension. It would be like someone using chalk to draw a circle around you on the floor and saying you are trapped when you can just step out of the circle.

[@RangeCMYK]

​@@SgtSupamanFrom the perspective of the 4D shape thing, couldn't it just take a step "sideways" (or whatever the 4d equivalent is) and escape?

[@SgtSupaman]

@@RangeCMYK , yes, that is what I was saying. To a 4D shape, a 3D shape is 'flat' (its size is 0 in some dimension), so it is trivial for it to get out of the 3D shape, because the 3D shape never contained it in the first place.

[@nanamacapagal8342]

If you're wondering about the dodecahedron-universe ending, this actually ties in to Plato's contribution to the platonic solids (plus the color scheme for the other 4 solids) Plato assigned the solids different classical elements: Tetrahedron = Fire (Red) Octahedron = Air (White) Cube = Earth (Green) Icosahedron = Water (Blue) Dodecahedron = Aether (Gold) The inside of the dodecahedron is a 4-dimensiomal 120-cell comprised of 120 dodecahedra (go figure), so it might be the higher-dimensional equivalent of aether... All the other 4d graphs are the remaining 4d platonic solids. In fact, the gold one orange stickman holds in their hand is the exact boss they were fighting against earlier: the hyperdiamond made of 24 octahedra (hence the octahedral artillery) EDIT: got air and water backwards oops

[@kendrakirai]

My own personal theory is that the method Euler’s used to send TSC away actually split him - one went to Physics, one went to Geometry. The two are, for lack of a better term, happening “concurrently”. (Let’s ignore the ludicrous amounts of time it would have taken Physics to happen - Time doesn’t seem to hold sway in these, merely causality. Perhaps, since between Physics, math, and geometry, we’ve handled what I’d consider three of the four most fundamental concepts of reality, the next one will be the fourth - Time.)

[@Stakatakataka]

@Stakatakataka I mean, it's a theory about a film based at least partly on headcanon and supposition rather than fact, so I suppose its pretty Matpat-y, yes. :)

[@JellowGelo]

I took this idea from "Animation vs. Geometry - An Over-Analysis", apparently the oddly looking shape is called a "24-cell", a regular 4d shape that is considered to be a "4-D Platonic Polytope". The reason why it is attacking TSC and Phi is because it is the only shape, in their plane, that is not symmetrical. The 4 colored platonic solids at the very end are referencing Plato's elements (fire, earth, air, water, Universe). Correct me if I'm wrong, because I truly find Alan Becker's animation vs math/science to be really interesting. And I'm getting hooked by it.

[@ace9u]

I didn't get you? Is the 24 cell the only shape in 4D that isn't symmetrical?

[@JellowGelo]

@@ace9u No. It is the only shape in the video that isn’t symmetrical on all sides because it is a 4D object in a 3D world. We do not see 4D objects because we are 3D creatures seeing 2D objects. Phi (Golden Ratio) is symmetrical whereas the 24 cell (in a 3D world) isn’t, which makes 24 cell the antagonist of this video.

[@惠心Megumi]

Also when the 24-cell bumps against the platonic solids to escape, they flash the same color.

[@Enderplays12]

To add to your 4 platonic solids, there's the fifth, the dodecahedron. In the Greek Theory of five elements, it represents aether, or eternity. Hence the fractals. A hypothetical "eternal" 3D object (which must be closed) means that it has to have one of its measurements as infinite. Since it is normal in its three dimensions, it then needs to have a fourth, which is why it contained the octaplex. It bridged between 3 and 4 dimensional geometry. Source: I made it all up.

[@ProactiveYellow]

I highly recommend (to fellow watchers here) watching jan Misali's video on the "48 regular polyhedra" which is a beautiful example of how the "three easy rules" for the platonic solids actually lack proper constraint. To them we simply add the rule(s) of being finite, closed, strictly convex, self non-intersecting polyhedra to get the five platonic solids we know and love, but relaxing these restrictions give us a wonderful world of highly symmetric objects that still lie within the "spirit" of the platonic solids, so to speak!

What i found most intriguing is the physicists that react to these talk about the geometry and history, the mathematicians reaction to this is focused more on the fractals. But in the last video (Anamation vs physics) mathematician got into string theory and quantum maths and physicist had a great time in the stellar mechanics. Its really amazing to me to see from the same video how the STEM field you applied into create a completely unconscious biases to the part that caused excitment. Dont get me wrong, this is an observation that is completely expected, though seeing in doctorate education makes me wonder in these 3 videos could be used to ascertain which STEM field a student all ready has a disposition towards and could help them determine which path to take. Personally im a stellar mechanics kinda guy and i knkw watching these 3 videos on my own i definitely leaned into this. After watching your, the physicist, the nuclear engineers videos i gained way more insight into how incredibly complex everything was in these 3 videos.

[@HalfEye79]

That reminds me of a topic in my Abitur. It was the verbal test in math. (That stick to me despite it being more than 25 years ago.) To say it bluntly it was forms evolving with dimensions. We had looked at two forms: The triangle and the square. Triangle: When we are at o dimensions, we have 1 point, 0 lines, 0 faces and 0 rooms. Its a dot. In 1 dimension, we have 2 points, 1 line, 0 faces and 0 rooms. Its a line. In 2 dimensions, we have 3 points, 3 lines, 1 face and 0 rooms. Its a triangle. In 3 dimensions, we have 4 points, 6 lines, 4 faces and 1 room. Its a tetrahedron. Two things are to be known: In order from one dimension to the next we draw one point in the new dimension and connect it to all other points. And these numbers look like pascal's triangle, without the leading 1. With A points, B lines, C faces and D rooms the next would be 1 + A points, A + B lines, B + C faces and C + D rooms. So in 4 dimensions it would be 5 points, 10 lines, 10 faces, 5 rooms and 1 ??? (body of the fourth dimension). Square: In 0 dimensions we have again 1 point, 0 lines, 0 faces and 0 rooms. Its a dot. In 1 dimension we have again 2 points, 1 line, 0 faces and 0 rooms. Its a line. In 2 dimensions we have now 4 points, 4 lines, 1 face and 0 rooms. Its a square. In 3 dimensions we have 8 points, 12 lines, 6 faces and 1 room. Its a cube. There is one thing to be known: In order to get from one dimension to the next, the existing form is doubled and the points, which were the same, are connected. With A points, B lines, C faces and D rooms the next would be 2 * A points, A + 2 * B lines, B + 2 * C faces and C + 2 * D rooms. So in 4 dimensions it would be: 16 points, 32 lines, 24 faces, 8 rooms and 1 ??? (body of the fourth dimension).

I previously made this comment on another math channel, but I like to conceptualize the fourth dimension by analogy to something from the book _Flatland_ (which I'm sure we've all read). The protagonist tries to explain the third dimension as, "Up, but not north." I think of the fourth dimension as, "Out, but not up." Here, the tesseract 3D "shadow" is a good analog, despite what Matt Parker says 😝.

my theory of the ending is that geometry guy went into higher dimensional space and saw an appearance of space cowboy, as he also exists in higher dimensional realities after entering a black hole and being capable of time travel (4D movement) and manipulating cosmic strings (10-11D interactions).

Hey! Dancer here, I wanted to add that the platonic shapes are also used in dance theory! With them, we show the range of possible movement within the reach of each limbs without mouving one’s center. The more precise one is the last one I think? With the most faces at least. That’s all for me, if anyone has more information Please let me know, and sorry for the errors in english, I’m french and trying my best. Great video, I learned a lot! Take care!

I remember drawing fractals on ms paint in schoo, it's actually really fun and easy to do 😂 At one point tho, the fractal becomes too big and there's a finite limit to how much you can increase the canvas 😂

The higher dimensional monster can be thought as the 24-cell
