@michaelcolbourn6719 his video "Animation vs. Minecraft Shorts Season 3 - All Episodes (20-30)" is a masterpiece! it's a very well made story, I highly recommend it! Even if you don't play/know/enjoy Minecraft.

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 > ???

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.

If Dr. Octavius became a pro wrestler after his lab accident, he would have the Octoplex as his special move.

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.

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.)

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.

The shape that was destroying everything was a four dimensional hyper diamond

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

Fun fact, the platonic solids were actually demonstrated in increasing order of vertices as the tetrahedron has 4, the octahedron has 6, the cube(hexahedron) has 8, the Icosahedron has 12, and the dodecahedron has 20. It's actually funny to note that objects after the tetrahedron are pairs with the vertices and faces swapped. so if we were to discover another layer of these solids it would probably follow a similar pattern of the swapping and would thus be discovered in a pair.

Alan Becker brought back so much Knowledge that I had thrown away. With your explanations, everything that I couldn't grasp before, is now easier to understand. Thank you.

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 😝.

I've gained a greater understanding and appreciation for the geometry in Alan's video because of this guy. Learning about the platonic solids makes the climax SO much more hype!

Welcome to the community :)

I COMMENTED ON THE VIDEO "can't wait for tom rocks maths to react to this" WHEN IT CAME OUT AHHHHHHHHH!!!!!!!!!!

The two kites constructed from the golden ratio were selected from the P2 and P3 non-periodic Penrose tilings, hence their relationship to the golden ratio. The square areas for the Pythagorean theorem part demonstrate one + phi = phi^2. And as many others have stated, the antagonist is the 24-cell, the only 4D Platonic solid without a perfect 3D analog (the cubeoctahedron and rhombic dodecahedron, taken together, best capture its essence).

As something as Universally simple as a stick figure, I feel like many of us got our enjoyment and extention of stickfigures creations from Alan Becker and his usage of his skills and knowledge integrated into his fast learning stick figures

Now that I watched this video again, I feel like I found a mistake. At 6:47 here we see the triangle being rotated by 150, but isn't that 120? I mean the angle on that side of the triangle is 60, so it should be 120 rotation instead.

yay been waiting for you :)

I like how i recognized the 4d rotation of the "graph theory blob" instantly lmao

I think all the platonic solids are referencing the 5 elements too, Fire, air, earth, water, and Aethos in that order, due to the colour that they glowed when the 24-cell was trying to break through them

this guy teaches 10x better than my math teacher

In some languages, this illustration of Pythagorean theorem is called Pythagorean Pants, lol

i wish youd mentioned the other regular polyhedra..... theyre so my beloved

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

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!

I read the "graph theory blobs" as 4-d regular polytopes

I've read somewhere, that what TSC is doing is constructing an icosahedron using mutually orthogonal golden rectangles. It has something to do with the vertices of these rectangles that relate to the icosahedron (d20) but I'm not sure.

26:00 I just visualise 4d objects as stuff that has edges in other slices of time, if you're not in the right slice of time then you can't see those edges. If an edge has vertices in 2 different slices of time then you see it fade out due to it moving through time and you can only see the chunk of it that's close to your slice of time.

We really a collaboration with Tom and Alan

Elemental correlation to the Platonic solids shows through as well, Red = Fire, Grey = Wind, Blue = Water, Green = Earth, and Gold = Ether

gallium gonzolium did a pretty good job. Well done Dr. Tom

something cool that was there is that the platonic solids are linked to different elements, the tetrahedron is linked to fire, the octahedron is air, cube is earth/rock, the icosahedron is water and the dodecahedron is metal or in the animation just golden for phi (i might have got some things wrong let me know if i did) something i forgot they shine the color of the elements fire/red air/gray earth/green water/blue (metal/gold probably not tho)

At 26:49 there are 4D 'platonic solids': an hypertetrahedron and an hypercube (teseracton) and maybe others regular 4-polytopes

Yes!

12:43 this has probably been said before but I'm pretty sure that the 2D version is the sierpinski carpet, the 3D version is called the menger sponge

21:35 By the first rule you mean it has to be convex and physical, not just 3D. You can use software to construct a 3D polyhedra with polygons of five sides, where each is a shape of a five-ray star, not just pentagon.

did you hear about 4D Golf? Because you said it is hard to visualize more dimensional Space and this game does exactly that by switching between various modes. It is a marvel of game design and geometry.

Reminding me of my Foundations of Advanced Mathematics professor from college, if he ever heard us mention "Straight Line", he'd let out a loud squeak since the definition of a line is that it's straight. He basically conditioned us into using the "proper" definitions.

17:04 Star Trek Logo Theorem is now my head cannon name for Euclid's inscribed angle theorem. 😁 The golden hand-glider (drawn by TSC and phi) is a dart shape composed of two Robinson triangles. This dart shape (and the kite shape drawn at 17:50 ) are used in the second type of Penrose tiling. For pretty diagrams, look up "Penrose tiling" in wikipedia.

Regarding to 4 dimensional space, I always like to think of it as time, it is because similar to Frames Per Second on a game, the way how smooth we move through time is what i think as 4D

Looks like everyone but Tom spotted that the attacking shape is 4D...

The sound work was incredible, even for an Alan Becker original

1:02 A dot is zero dimensions. A line is one dimension. So it is: "Which is like 0-D to 1-D" 1:21 It only became 2-D when orange stickman broke out of the line.

The 4D Shape attacking The Second Coming and Phi is a 4D Hyper Diamond or just 24-cell

the mandlebrot set is the dragon curve thing you talked about.

I expected Tom to mention Duals of Polyhedra. When Stickman and Phi connect the centers of the faces of the octahedron, they create a cube. Vice versa, connecting the centers of the faces of a cube creates an octahedron. Dodecahedron and icosahedron are similarly each other's dual, but tetrahedron is special, because it's its own dual.

I’m holding out hope for an Animation Vs Crop Circles

Seeing the orange stickman appear many times through out the "4-D" space made me think of something I hadn't befote. It made me wonder "could it be that by going into a higher dimension everything in lower dimensions can be observed all at once?"

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).
