So if I undertand this right: The biologists saw and realized what was happening, described it to the mathematicians, who formalized it as a precisely defined shape, and described it to computer scientists, who programmed that definition as something a something a computer could model, which was analyzed by physicists, who analyzed and confirmed the shape would be stable packed at that scale. In this story, I'm the chemist
I remember seeing something about this, I thought "what?! you can't just discover a new shape, but whatever" now that you made me think about it, I came up with "discovering a new shape is like discovering a new number." It was always there, and there's literally nothing standing in anyone's way of finding/seeing it. They just need the right circumstance to use it or see it in use.
More than discovering a new shape, they discovered a new shape in "nature" concrete and frequent enough to merit his own name, instead of a generic name
@@goawaygoawaynow I think the most proper to call it is "Scientists gave a new name to an object which they found in nature and which nobody thought about before". But... that doesn't sound aa catchy, admittedly.
I just want to point out that the way you said, “some generic foreign city” while casually showing one of the most iconic buildings in the world in the background was pure genius lol well done

Biologists: We're confused. *Inter-disciplinary science team, assemble!* Four different kinds of scientists, muttering: Okay, so it can't be a regular prism...
It's sad that it's acceptable these days to show that kind of thing to kids. My parents used to spank me if I even mentioned a kangaroo so I wouldn't be brainwashed into becoming an Australia. This generation has really lost all morals. 😥 :((
"Matt makes a shape out of things he found around the place he's staying while on the holidays" actually everyone's second favorite series after calculator unboxing and reviewing
Proposal: a prism with one anti-prism edge is a "first-order antiprism"; two edges make a "second-order antiprism"; an anti-prism is an "nth-order antiprism," with n being the number of edges on the parallel faces I suppose then a scotoid could be considered a fractional antiprism
That still isn’t enough to get a full description. You also need to define which face you use for the shape name (would Matt’s shape be a pentagonal or hexagonal 1-antiprism?), and for 2-antiprisms or higher you also need some way to denote the relative positions of the antiprism bits. Not saying this is a bad idea, but in general when something doesn’t have a name, it’s more likely that there’s no need for it than that nobody could think of a good name. :/
Nice, the sciences don’t have to be separate! When they work together amazing discoveries like these can happen. Teamwork is much better than petty rivalries.

Funnily enough, 'scutoid' DOES actually have a meaning, even though it was based on someone's name. It actually means 'scale-like', as the base word 'scute' was derived from the latin 'scutum' (meaning 'shield') and is currently used to refer to the sub-dermal types of 'scale' found on creatures like alligators, though it is often used for the wider and thicker belly scales of snakes and lizards as well. And now you know.
"In short, there's pentagons to the left of V" Oh no "Hexagons to the right" Matt, please don't "Here Y Am" Oh God he's actually doing it "Stuck in the middle with Scu...toid" I honestly would have unsubscribed if I didn't love this channel so much.

Funny, as an Aussie I realised you were at Circular Quay from the sandstone wall before you even turned around to the coat hanger. PS that Little Creatures is a nice drop.
I’ve actually found a scenario where an antifrustum shows up. If you take 6 points in 3D space and connect them all to each other using exactly 2 different lengths of pipe-cleaner, there are 6 possible arrangements where all the pipe-cleaners are straight: 1. A prism with triangular ends and square sides. 2. An octahedron (aka. triangular antiprism). 3. A short pentagonal pyramid with all edges equal. 4. A tall pentagonal pyramid where the edges to the peak equal the diagonals of the base. 5. A triangular frustum where the ratio of the bottom and top edges equals the ratio of the diagonals to the edges of a pentagon (aka. φ). 6. A triangular antifrustum with that same ratio. (Note that the corners of the top extend slightly beyond the outline of the base.) I don’t know if it’s useful for anything, but I thought it was neat.
Thanks for coming to present to us here in Australia at Sydney Grammar School, it helped many of us gain a better perspective on how to extrapolate from 3D shapes into the much more abstract realm of 4D shapes.
Matt, thank you so much for that clear explanation. I always love learning something new! The pipe-cleaners really helped with the visualization, we can spend so much time on computers that we forget model doesn't have to be virtual. :)

My favourite type of prismatoid is the cupola. The two parallel faces have n and 2n sides respectively and they are connected by squares and triangles (or, I suppose, rectangles and triangles in case of non-Johnson versions).
Scutum or mesoscutum is the hard "back" part of a certain body segment in many flying insects. It's the triangle in the picture of the beetle, if I'm not mistaken.

"The scutoid derives its name from a bastardization of the song Stuck in the Middle with You, where the famous lyrics are altered to 'pentagons to the left of me, hexagons to the right, here I am stuck in the middle with scu....toid.'" - Wikipedia
I was thinking the exact same thing while watching the video... I'm pretty sure I saw something like that while eating pomegranate. One more reason to enjoy them next Autumn!
Phenomenal job explaining the discovery and giving pertinent background information. Nice little bit of trivia thrown in as well; always good to have connections!
Marvelous! Thank you! I had seen the articles, but thanks to this video, I understand the shape much, much better. The wireframe image in most of the articles going around that I saw made it look, to my eye at least, more like a prism with 3 'ends', as if two top faces had both joined to a single bottom face and were somehow fused. That seemed unlikely, especially if it was something that would pack reasonably.
TheUnnamedGent I thought about that as well... doesn't look like there would be a reason for it not existing...but I guess it was not relevant to explain this series...
No, you would turn the top face half way to the next symmetry point and then have two vertical(ish) edges going from/to each corner, making triangular sides. It's more like an anti-prism with the top squished in.
In fact a prism becomes an antiprism as soon as the top and bottom shape are even a tiny fraction out of alignment. The same would apply to a frustum i would think
An excellent bit of recreational mathematics related to this talk is finding how combinations of Archimedian solids can fill space. Archimedian solids have all faces regular polygons, all vertices are indistinguishable, but the faces need not all have the same number of edges. The prisms and antiprisms are Archimedian if the end plates are regular and if the prism's rectangles are squares, and the antiprism's triangles are equalateral. Now the goal is to fill Euclidean space with Archimedian solids such that vertices are indistinguishable. Here are some examples to get you started: We can fill space with just cubes. Every vertex has 8 cubes around it. We can use just triangular prisms: each vertex is surrounded by 12 prisms. By alternating layers of cubes and triangular prisms, we can fill space with 6 triangular prisms and 4 cubes around each vertex. We can fill space with tetrahedrons and octohedrons - this is illustrated by M. C. Esher's print "Flatworms". Surprisingly, the full list of such space fillings was only produced in the 1990s. I can't recall off hand how many, but it is about 20 to 30 of them.
I love this topic, the inclusivity of biology in this hits close to home for me. I've always wondered how cells manage their shapes with minimal information and this seems to hint at some of those answers.
SecularMentat well, I guess it's the same like bees making hexagonal shapes, they build them round and heat them up, until they melt them together to form hexagons. Or how soap bubbles will always form Y shaped structures, when 3 or more come together, it's just the shape with the least surface area compared to it's volume, so they will naturally fall into it.
Break it down to simpler shapes and add their volumes together or Do some double integral wizardry or Build it and fill it with liquid thereafter take the liquid and measure it or Build it and put it under liquid to measure the volumetric displacement
I was typing a rant during the video, until he got to the part about biology and its possible applications. The headlines going around really does a disservice to this development, because I read the headline and thought "well that's stupid, can't anyone randomly connect a couple of edges until they get a shape no one has ever made before".
AndyAndromedaArt Also, at the very beginning he stands in front of the Great Wall of Giza which is located in Berlin as well, right between where east and west russia were which were divided after ww2
Today by chance I found your videos on the dodecahedron and the scutoid. I love them because I made many shapes based on unfolding with my students at a Dutch high school during art classes. Once I turned a dodecahedron inside out so that a cube appeared.
Linguistics comment: To an English-only ear, Clara's pronunciation may sound like s-cutoid. Spanish speakers commonly pronounce an "eh" sound before an English word starting with "s" (or English loan words drop the initial vowel). This is part of why "Spain" and "España" are the same country in different languages. Interestingly (to me and maybe to you), a French accent or French versions of words that begin with "s" in English follow a similar pattern, but they sometimes drop the "s" itself. So "state" is "estado" in Spanish, and "etat" in French. Knowing patterns like these makes it easier to correctly guess the meanings of words in either of those languages.
Yep! The one pronunciation thing that's messing with me in this vid (and it's probably done on purpose to annoy people) is where the hell Matt is getting the O that he's replacing the U in scutoid with lol.
My. God. BRILLIANT, Matt. Well done, with that song reference. Absolutely brilliant 😂😂 "pentagons to the left of V, 6:26 hexagons to the right. Here, Y am 6:31 stuck in the middle 6:33 with scu- "
At around 7 min, you're pointing out how, with that "Y" on the side of the shape, the side faces are no longer all flat; some of them have to be curved. *But no, they don't have to!* If you just start with a pentagonal prism, and make a planar slice across one vertex down to the middle of the corresponding vertical edge, you can make a polyhedron - all flat faces - that has all the same properties. But I take it that, in the problem that generated these shapes, they had to pack with each other without leaving gaps; and maybe that wouldn't be possible with the all-flat-faces variety. Fred
falxonPSN turns out the word "frustrum" doesn't actually exist, but if it did it would be related to the Latin for frustration. The correct term in 3D graphics is a "camera frustum" and many, MANY people get this wrong, and have done for a very long time. See the Wikipedia article for a brief note on the history of this misspelling.

I was thinking the exact same thing while watching the video... I'm pretty sure I saw something like that while eating pomegranate. One more reason to enjoy them next Autumn!
That's a good point actually.
So now I have to search how to pack pomegranates
Nice. Another productive day.
It approximates Voronoi cell packing, at a guess.
Phenomenal job explaining the discovery and giving pertinent background information. Nice little bit of trivia thrown in as well; always good to have connections!
"thrust 'em" is my new favorite shape
👌🏻O O O F👌🏻
mind. blown. Love the interdisciplinary connection and a real-world scenario that generates new pure math. Wow!
You should make a video on the geometry of the Sydney Opera House. Many people know the story but most do not.
I feel like I watched a video on that, but I can't remember who it was by :/
He's done that already in /watch?v=zXoJlRFbktw
Thanks! I thought it was Matt, but I wasn't sure if it was Veritasium and I didn't find it with a quick search!
Well done. This was fascinating, and the story arc is brilliant!
I want more episodes of MMASOOTHFATPHSWOH !

Marvelous! Thank you! I had seen the articles, but thanks to this video, I understand the shape much, much better. The wireframe image in most of the articles going around that I saw made it look, to my eye at least, more like a prism with 3 'ends', as if two top faces had both joined to a single bottom face and were somehow fused. That seemed unlikely, especially if it was something that would pack reasonably.
What about an anti-frustum?
I like openscad.
TheUnnamedGent I thought about that as well... doesn't look like there would be a reason for it not existing...but I guess it was not relevant to explain this series...
Well anti-frustum would be just frustum rotated 180°, so it technically exists, but it's not something new.
No, you would turn the top face half way to the next symmetry point and then have two vertical(ish) edges going from/to each corner, making triangular sides. It's more like an anti-prism with the top squished in.
That makes sense, but I'm guessing there still is a good reason not to make it a shape.
In fact a prism becomes an antiprism as soon as the top and bottom shape are even a tiny fraction out of alignment. The same would apply to a frustum i would think
Literally threw my arms in the air during the title card because this really is my favorite segment
...so, was cutting your hair that short the price you had to pay for entering TheMathologer's domain?
He shaved it off to discover another shape!
That's the price he paid for going bald.
Matt Parker doesn't go bald, he Parker Squares growing hair.
TheLimalicious good one
Bald head = Parker Hair (obvious and done before - Parker Original?)
I appreciate the appropriate choice of the Shapes box as building material to make shapes
At first he tried it with a hexagon at the bottom and a square at the top. Turns out, that was a Parker Square of a scutioid.
An excellent bit of recreational mathematics related to this talk is finding how combinations of Archimedian solids can fill space.
Archimedian solids have all faces regular polygons, all vertices are indistinguishable, but the faces need not all have the same number of edges. The prisms and antiprisms are Archimedian if the end plates are regular and if the prism's rectangles are squares, and the antiprism's triangles are equalateral.
Now the goal is to fill Euclidean space with Archimedian solids such that vertices are indistinguishable.
Here are some examples to get you started: We can fill space with just cubes. Every vertex has 8 cubes around it. We can use just triangular prisms: each vertex is surrounded by 12 prisms. By alternating layers of cubes and triangular prisms, we can fill space with 6 triangular prisms and 4 cubes around each vertex. We can fill space with tetrahedrons and octohedrons - this is illustrated by M. C. Esher's print "Flatworms".
Surprisingly, the full list of such space fillings was only produced in the 1990s. I can't recall off hand how many, but it is about 20 to 30 of them.
4:56 I would like to humbly suggest a fitting name . . . .
The Parker Prism!!
Excellent introduction to the scutoid! Thank your for producing and posting this helpful video.
That moment you wish your were still a high school maths student.

I love this topic, the inclusivity of biology in this hits close to home for me.
I've always wondered how cells manage their shapes with minimal information and this seems to hint at some of those answers.
SecularMentat well, I guess it's the same like bees making hexagonal shapes, they build them round and heat them up, until they melt them together to form hexagons. Or how soap bubbles will always form Y shaped structures, when 3 or more come together, it's just the shape with the least surface area compared to it's volume, so they will naturally fall into it.
I had your voice in my head for a moment, but couldn't figure out who it was. Thankfully, the subscription list had me covered
But how do you find the volume?
Break it down to simpler shapes and add their volumes together or
Do some double integral wizardry or
Build it and fill it with liquid thereafter take the liquid and measure it or
Build it and put it under liquid to measure the volumetric displacement
Displacement method... lol
Oh god the double integral method giving me some bad memories from calc 3. Lol
Split it into simpler shapes , put all their formulas into one and clean that mess up.
You can use Cavalieri's principle aka triple integrals to find out
I was typing a rant during the video, until he got to the part about biology and its possible applications. The headlines going around really does a disservice to this development, because I read the headline and thought "well that's stupid, can't anyone randomly connect a couple of edges until they get a shape no one has ever made before".
I made a blombous.
Umm. At 0:33 that's the eifel trade centre so you in Berlin fam

Matti Kauppinen good troll 10/10 would fall for again
Videos like this make me so excited about geometry!
You could say it is a prism in the streets and a prismatoid in the sheets.
That was beautifully explained you're an amazing educator Matt.
New form 2b: anti-frustum 👍😁
Today by chance I found your videos on the dodecahedron and the scutoid. I love them because I made many shapes based on unfolding with my students at a Dutch high school during art classes. Once I turned a dodecahedron inside out so that a cube appeared.
Bit of anti prism, bit of prism, but only a prismatoid? I declare it a neutra-prism!
I actually do love the Matt makes shapes of found things segments.
You find the craziest people, I love them so much
Your subtitles are slightly off at the end: "escudo" should be "scutum".
Linguistics comment:
To an English-only ear, Clara's pronunciation may sound like s-cutoid. Spanish speakers commonly pronounce an "eh" sound before an English word starting with "s" (or English loan words drop the initial vowel). This is part of why "Spain" and "España" are the same country in different languages.
Interestingly (to me and maybe to you), a French accent or French versions of words that begin with "s" in English follow a similar pattern, but they sometimes drop the "s" itself. So "state" is "estado" in Spanish, and "etat" in French.
Knowing patterns like these makes it easier to correctly guess the meanings of words in either of those languages.
Yep! The one pronunciation thing that's messing with me in this vid (and it's probably done on purpose to annoy people) is where the hell Matt is getting the O that he's replacing the U in scutoid with lol.
To me, it just looks like a regular old prism with one corner lopped off; well, that's what I first thought...
i think the difference is that it is pack-able. a prism with a corner lopped off wouldn't be.
My.
God.
BRILLIANT, Matt. Well done, with that song reference. Absolutely brilliant 😂😂
"pentagons to the left of V,

hexagons to the right. Here, Y am

with scu- "
At around 7 min, you're pointing out how, with that "Y" on the side of the shape, the side faces are no longer all flat; some of them have to be curved.
*But no, they don't have to!*
If you just start with a pentagonal prism, and make a planar slice across one vertex down to the middle of the corresponding vertical edge, you can make a polyhedron - all flat faces - that has all the same properties.
But I take it that, in the problem that generated these shapes, they had to pack with each other without leaving gaps; and maybe that wouldn't be possible with the all-flat-faces variety.

Excellent video! It’s wonderful to have you in Australia again 😋
What happens if a Prism and an Antiprism collide? ;)

I love how excited they are when they talk about it. Most people just don't care about this stuff sadly 😞
You in mah city and you don't even tell me?!?!?!?!?!?
love this video series! had lots of fun crafting my own hexastick and will proceed to create some scutoids and try to stack them :D
Sorry, but isn't it a frustrum? This is a term we use often in game engine coding for representing a camera's view angle.
falxonPSN turns out the word "frustrum" doesn't actually exist, but if it did it would be related to the Latin for frustration. The correct term in 3D graphics is a "camera frustum" and many, MANY people get this wrong, and have done for a very long time. See the Wikipedia article for a brief note on the history of this misspelling.
@@meowsqueak very interesting. I had never seen the other spelling until this video. Even the Unreal Engine docs are wrong then.
