    • @JonathanMandrake
      @JonathanMandrake 2 роки тому +8

      To be fair, the difference is the definition: Jan misali also accepts polygons that aren't strictly convex, which allows for self intersection, planar tiling and the other things he shows, but if you were to actually define it, most mathematicians would probably restruct them to be strictly convex, and call the other ones semi-polygons or something like that. They're still interesting, but also different. It's actually quite similar to how some people say 0 is prime, while most mathematicians define primes as natural numbers (excluding the 0, should it be considered a natural number in this system), and 0 acts quite different than the other primes

    Awesome video!! I’ve been searching for ages for an answer to why there are only 5 Platonic solids in 3 dimensions. Not only is this the first explanation that I find instantly intuitive and concise, it’s also demonstrated beautifully. The extension into the higher dimensions and reference to fewer dimensions is also a wonderful way to contextualise the whole concept of perfect solids. Thanks so much! 🙏❤️

    I just did a project on 4-dimensional regular polytopes, and there are actually 19 of them (that I could find). These include the regular star 4-polytopes and the 4D honeycombs.
    Additionally, there are definitely more than three regular polytopes in dimensions higher than the fourth, due to the existence of hypercube honeycombs. So that makes at least four. Whether the star polytopes are applicable to the fifth, sixth, etc. dimensions I'm not sure of. Some sources say no.
    In the end, this just comes down to how we define a regular polytope. This video makes the assumption that regular polytopes are convex, finite, do not have any holes, aren't self-intersecting, etc. Without these assumptions, more becomes possible. :)

    Whatever version of D&D they play in the 5th dimension must be really boring having only three kinds of dice.

      you can have other shapes of dice and still have them be equally weighted, they just start becoming cylinders with shaped faces on the sides, or weird shapes with some sides you dont land on.

    • @OverpepperedSoup
      @OverpepperedSoup 5 років тому +16

      You can take care of that by repeating some of the labels. Some games using 3d dice already do that, for instance cube dice with only 3 numbers (each number repeated twice).

      @skulleeman 5 років тому +11

      @@kirillmed1 I'm no expert, but you may get problems with the dice landing on the "flat side" in the same way that 2d dice would land on their flat side in 3 dimensions. You could always extrude out and put smooth caps on the ends which you don't want the die to fall, but it's starts to feel less "dicey" at that point.
