Paused to count. Yep, it's 24 vertices total with triangular faces. But it is not the Hyperdiamond! It's the weird one in 4 dimensions that doesn't have a lower dimensional analogon.
Alan Becker really has made something special with his time on UA-cam. Amazing educational content, gripping and emotionally compelling narratives, awesome fight scenes, and all that with just stickmen and no dialogue whatsoever! It’s no wonder his videos get millions of views!
I've only seen the maths and science ones. All today as I'd never heard of it until this video. His other ones all looked like Minecraft vids so I haven't bothered with them
@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 > ??? New Animation vs. Education video yay
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.
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 huh yeah you're right. I assumed because at some points it looked almost exactly like a hypercube it was one, but looking at it again it has way too many lines.
"It can't be reasoned with, it can't be bargained with…it doesn't feel pity or remorse or fear… and it absolutely will not stop. Ever. Until you are dead. It's called... a 24-cell."
The shells of many viruses are also dodecahedrons and ecosahedrons (discovered by Crick of DNA fame). Apparently, they provide a really solid structure of repeatable shapes, because they are so geometric.
Honestly this man is amazing, always inspiring and carrying a happy smile. Currently in the process of doing my application for maths at Oxford, and I would not be in this position if not for Tom. Been an inspiration since day one and hope that you carry on what you do
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.
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
This is my favourite of the three "animation vs ..." series, I absolutely love geometry. First time I watched it through I was constantly on the lookout for any reference to divine geometry, the closest I could find was pythagoras and the platonic solids.
Yess!! I’ve been checking my feed every day for this video!! Love your reactions to these animations, they’re really well explained and you show such appreciation for the fundamental laws that create our universe. Can’t wait to see your reactions to Alan’s future work with this series :D
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.
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 , 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.
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 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.
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.
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.
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
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 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. :)
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!
This’ll be fun! I’ve been waiting for the reaction videos just because I like watching the reactions of experts. I’ve already watched the over analysis so I’ve probably become a geometry nerd over the week, but I still want to see your academic reaction lmao
The golden ratio, often denoted by the Greek letter φ (phi), is approximately 1.618. It appears when a line is divided into two parts such that the ratio of the whole line to the longer part is the same as the ratio of the longer part to the shorter part. This ratio is found in various aspects of art, architecture, and nature.
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!
These animations have an insane amount of detail, the dots at 15:12 bounce of at an angle and that angle is shown to us and the size of the angle pops up to one second 😮
@@suhailraja7797 Not all graphs can be drawn just in 2D, but every object consisting just of points and lines between them is a graph. For a graph that can't be drawn in 2D, try drawing every line between five points so that the lines only meet at the five initial points; it can't be done, so it can't properly be represented in 2D, but it is still a graph.
in fact, all the shapes seen within the final dodecahedron are the 4D Platonic Solids: in particular we see our 24-cell hyper-diamond, as well as a Tesseract (8-cell, or hyper-cube) in green, a pentatope (5-cell, a hyper-tetrahedron) in red, and a hyper-icosahedron (600-cell) in blue. the two missing are the hyper-octahedron (16-cell, the tesseract’s dual polytope) and the hyper-dodecahedron (120-cell, which may be what these are all contained within)
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
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.
My jaw is aching as well!! Loved the original art and love the way you jump in with pointers and keep us on track because I'm lost without you. Thanks and keep up the great work.
I started with "nuclear physicist reacts" and watched like a dozen different high-end-smart people since. You're the only one I actually subscribed to. I love your energy and the explanations. Keep up the good work.
Fun fact, the "kite" shape is actually something that Roger Penrose thought of. If you look up "kite and dart Penrose tiling" it wont disappoint you :) Also, I remember seeing that if you take the limit of "kite shapes" divided by the "dart shapes" in the pattern that forms, you will get phi, which is nuts.
We saw 1d, 2d, 3d and 4d shapes. What I found interesting is that when attacked, stuff showed the menger sponge underneath, which has a fractal dimension of between 2 and 3
17:05 That isosceles triangle (before it turns into a glider), had the sides opposite to the symmetric angles (of 54 degrees) of a value of 1 unit, which is why the inverse of the golden ratio at the side shared by the 2 smaller triangles actually important
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).
In the most genuine and non-weird way possible: I love the way you love maths. I have been actively looking for your take since it first came out. Thanks for sharing your insights 😀
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.
Me and another commentor from a different reaction video have come up that the blob you see is actually a 4th dimensional entity and it isnt capable of being trapped by anything from the 3rd dimension. When he throws the dodecahedron, he actually timed the through perfectly for all its points match up to a single spot and that traps it and the dragon fractals is its 4th dimension being shaved off into them.
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.
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. That being said what did the other ppl on the channel think? Edit: a word
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.
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 was looking for this comment! I read so many books about the golden ratio, this was really the most exciting. And I felt he missed the simpler things
21:42 You need to specify that your polyhedron is convex in order to obtain only the platonic solids. jan misali made a video some years ago about how many polyhedra there are if you don't. (The Kepler-Poinsot polyhedra are only the beginning.)
I think the Hypercube is my favorite 4D shape for visualizing what a 4-dimensional shape is. A still image works in a way, but the one where it... moves in a straight line on the 4th dimensional plane does a great job of showing how it all fits together. Every time you go up a dimension, you take what you had before and translate it onto a new axis and connect all the previous points, which is the most obvious to me with a square -> cube. So, if you extrapolate one step farther, you get two cubes, with each point connecting in such a way that you now, without rotating in the 4th dimension, connect each point of the new cube to the relative original point on the first cube. When you move it in a straight line in line with the faces, you get this wild image where it looks like the central cube stretches off to one side and becomes the side "face" shape of the original, and then it expands around as it becomes a square-like frame toward the right-hand side to make a cube on that side, then it morphs back inside to the center again. It's so weird to describe, but somehow, watching it go over and over, it just makes sense to me.
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!
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)
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.
Youre statements about the platonic soilds reminded me of a video Id love to see you react to. "There are 48 regular polyhedra" by Jan Misli. Its a great video about a very strange part of math
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.
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

@@broging_bread entirely possible! But you'd also think that Minecraft would be involved too if AvA was connected to other subseries.
@@kendrakirai so wait, what are the other 3 concepts? I assume Space, is one of them? I tried to find it on google and it only explains Space and Time
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!
Yeah, truly awesome video
Definitely an 😃 amazing video! I shall watch it again!
Oh my how easy to udnerstand you explaining everything! I'm literally learning rn! Thank you! 🎉❤
The moment that video dropped I was looking forward to your reaction and explanation.
This’ll be fun!
I’ve been waiting for the reaction videos just because I like watching the reactions of experts.
I’ve already watched the over analysis so I’ve probably become a geometry nerd over the week, but I still want to see your academic reaction lmao
Looks like everyone but Tom spotted that the attacking shape is 4D...
been waiting for your reaction on this!! your videos are so great :)
The golden ratio, often denoted by the Greek letter φ (phi), is approximately 1.618. It appears when a line is divided into two parts such that the ratio of the whole line to the longer part is the same as the ratio of the longer part to the shorter part. This ratio is found in various aspects of art, architecture, and nature.
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!
Intro correction: that would be 0 dimensions to 1 dimension (zero-D to one-D).
These animations have an insane amount of detail, the dots at 15:12 bounce of at an angle and that angle is shown to us and the size of the angle pops up to one second 😮
This is what i've requested 5 days ago in my comments at your reaction to Animation vs Math
Thx for making this vid its funny and cool at the same
I was waiting patiently for this >.
Sameeee
1:06, no that's 0d to 1d, lines don't have a second dimension because they make up every other shape that has an edge
Thank you, just wanted to mention it myself
the villain of the video isn't a graph its a representation of a 4d shape
I mean, that's still a graph.
@@themathhatter5290 graphs are just edges with connections to them so aren't they just 2D?
@@suhailraja7797 Not all graphs can be drawn just in 2D, but every object consisting just of points and lines between them is a graph. For a graph that can't be drawn in 2D, try drawing every line between five points so that the lines only meet at the five initial points; it can't be done, so it can't properly be represented in 2D, but it is still a graph.
whats next? animation vs chemistry? animation vs history? animation vs biology? animation vs geography?
probably chemistry
It is probably gonna be animation vs multiverse
Animation vs. Calculus?
@@morganansell4526 thats just vs math
@@oneleaf11 so was vs geometry
Thank you so much for your brilliant comments and interpretation. Fantastic!
Someone in the comments of that video gave a really good explanation as to how this video explains the four dimensions in each part of the video
in fact, all the shapes seen within the final dodecahedron are the 4D Platonic Solids: in particular we see our 24-cell hyper-diamond, as well as a Tesseract (8-cell, or hyper-cube) in green, a pentatope (5-cell, a hyper-tetrahedron) in red, and a hyper-icosahedron (600-cell) in blue. the two missing are the hyper-octahedron (16-cell, the tesseract’s dual polytope) and the hyper-dodecahedron (120-cell, which may be what these are all contained within)
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
You know an animation vs. geometry video is peak when a mathematician is smiling to the ears watching it
that "graph thing" is actually a 4-dimentional shape called a 24-cell or icositetrachoron en.wikipedia.org/wiki/24-cell
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.
Imagine having him as a teacher and then he takes his shirt off to show a tattoo 😂
i was waiting for this thank you
My jaw is aching as well!! Loved the original art and love the way you jump in with pointers and keep us on track because I'm lost without you. Thanks and keep up the great work.
yay been waiting for you :)
I started with "nuclear physicist reacts" and watched like a dozen different high-end-smart people since. You're the only one I actually subscribed to. I love your energy and the explanations.
Keep up the good work.
Welcome to the community :)
A point becoming a line is going from 0D to 1D, not 1D to 2D. It doesn't become 2D until the stick figure comes out of the line.
Fun fact, the "kite" shape is actually something that Roger Penrose thought of. If you look up "kite and dart Penrose tiling" it wont disappoint you :)
Also, I remember seeing that if you take the limit of "kite shapes" divided by the "dart shapes" in the pattern that forms, you will get phi, which is nuts.
We saw 1d, 2d, 3d and 4d shapes. What I found interesting is that when attacked, stuff showed the menger sponge underneath, which has a fractal dimension of between 2 and 3
17:05
That isosceles triangle (before it turns into a glider), had the sides opposite to the symmetric angles (of 54 degrees) of a value of 1 unit, which is why the inverse of the golden ratio at the side shared by the 2 smaller triangles actually important
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).
I love watching mathematician's raw reactions to these animations!
Him : relatively high school geometry
Me : I learnt them in elementary school
In the most genuine and non-weird way possible: I love the way you love maths. I have been actively looking for your take since it first came out. Thanks for sharing your insights 😀
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.
There's a really fun video about the platonic solids by Jan Misali called "There are 48 regular polyhedra" :)
Not only does Alan make educational animations, mathematicians explain what is going on.
that "graph theory" thing looks like its rotating in 4D. When it was shooting, it shot what looks like the 3D "faces" of the 4D shape.
WAS 16:15 A JOJO REFRENCE??????
I love all your videos my father passed away so I watch your video to make me happy❤❤❤ 😢
Knowing the dots placed for orange to be picked up before he does it drops the facade of being a live/blind reaction 🎉 got ya 😂❤
Me and another commentor from a different reaction video have come up that the blob you see is actually a 4th dimensional entity and it isnt capable of being trapped by anything from the 3rd dimension. When he throws the dodecahedron, he actually timed the through perfectly for all its points match up to a single spot and that traps it and the dragon fractals is its 4th dimension being shaved off into them.
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.
In a couple of years we'll be getting Animations vs Noncommutative Rings and it'll still be great
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.
That being said what did the other ppl on the channel think?
Edit: a word
Thanks for the explanation of Phi and the golden ratio! I really did not understand it first time watching
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.
Crazy thing with fractals and the measurement of coastlines is that the smaller detail you measure a coastline with increases the coastline
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 was looking for this comment!
I read so many books about the golden ratio, this was really the most exciting. And I felt he missed the simpler things
I asked my teacher to show animation vs math to my class and they loved it
21:42 You need to specify that your polyhedron is convex in order to obtain only the platonic solids. jan misali made a video some years ago about how many polyhedra there are if you don't. (The Kepler-Poinsot polyhedra are only the beginning.)
Bro predicted it.
Hey I totally recommend a vid by Jan Misali called “there are 48 regular polyhedra” which is really good and talks about the Platonic solids
POV Allen Becker in his basement making this starting to grow a beard (I have been hear for years)
Props to him for explaining everything
I think the Hypercube is my favorite 4D shape for visualizing what a 4-dimensional shape is. A still image works in a way, but the one where it... moves in a straight line on the 4th dimensional plane does a great job of showing how it all fits together. Every time you go up a dimension, you take what you had before and translate it onto a new axis and connect all the previous points, which is the most obvious to me with a square -> cube. So, if you extrapolate one step farther, you get two cubes, with each point connecting in such a way that you now, without rotating in the 4th dimension, connect each point of the new cube to the relative original point on the first cube. When you move it in a straight line in line with the faces, you get this wild image where it looks like the central cube stretches off to one side and becomes the side "face" shape of the original, and then it expands around as it becomes a square-like frame toward the right-hand side to make a cube on that side, then it morphs back inside to the center again. It's so weird to describe, but somehow, watching it go over and over, it just makes sense to me.
wait... trump's hairs is in the golden ratio!?
I can nver unsee that XD
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!
At 26:49 there are 4D 'platonic solids': an hypertetrahedron and an hypercube (teseracton) and maybe others regular 4-polytopes
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)
Jan Misali made a great video explaining how the 5 Platonic solids are not the only regular polyhedra. You should react to it
The 4D Shape attacking The Second Coming and Phi is a 4D Hyper Diamond or just 24-cell
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.
yup, you are right. good catch
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
Youre statements about the platonic soilds reminded me of a video Id love to see you react to. "There are 48 regular polyhedra" by Jan Misli. Its a great video about a very strange part of math
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.
Thanks for the reaction❤
aaaa i got so freaked out and got so scared by looking at just the simple fractals
I COMMENTED ON THE VIDEO "can't wait for tom rocks maths to react to this" WHEN IT CAME OUT AHHHHHHHHH!!!!!!!!!!
phi was actually seen at the end of the video from animation vs. math.
I think that's a Sierpinski carpet. The Menger sponge is the 3D version. Also, the area isn't just finite... it's zero :)
i wish youd mentioned the other regular polyhedra..... theyre so my beloved
Our 4th dimension is time.
That homer simpson shirt is dope
In 19:42. The thing that five showed is that anything inside that box gets completely destroyed cuz of the presure in side it.
Drawing a Heighway Dragon Curve is the only use I've ever found for programming in Logo.
Imagine if a mathematician reads Steel Ball Run
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
