    • @SplendidKunoichi
      @SplendidKunoichi ปีที่แล้ว +2

      "2d coordinates that can be compressed (normed) into a single coordinate" is an all but complete operational definition for the field of complex numbers (the formal name for this would be the "canonical real structure" if im not mistaken). its no exaggeration to say every STEM field finds its own wildly different favorite use of complex numbers.
      but more than that, the entire subject of algebra, as you may or may not know, has a pretty large hole in it that isn't actually possible to close using anything other than these same 2d numbers. so in a way, they really are the very thing ensuring any and all reasoning you do using your school textbook math will be logically rigorous; that it has the consistency to carry useful meaning by default in whatever practical context you can give it.

    Many years ago I was working in the supermarket industry. We characterised shoppers by their propensity to shop in different areas: meat, dairy, fresh veg, canned goods etc, giving us a set of n scores. We used these as coords in n dimensional grocery space. This "space" was really easy to conceive and navigate. That was the only time I've ever felt comfortable with n>3 dimensions. Until I watched this video, that is. Thanks.

      Also the corners get farther apart. A corner of an 100-D cube is sqrt(100)=10 units distant from the centre (assuming that all sides are 2 units long).
      One visualisation of this I like uses a projection into 2 dimensions.
      One can cut a 3D cube with an xy plane rotated 45 degrees around the x axis. This cut gets you a rectangle of dimensions 2 * 2.82. This plane also cuts out a circle of radius 1 from a sphere or radius 1. If you draw it, you'd notice unused space -- there's a margin of 0.41 units on each side, and an even bigger margin in the corners.
      A similar plane cut can be performed in 100 dimensions. A cut along orthogonal vectors a=(1,0,0,0 ...) and b=(0,1,1,1 ...) will result in a rectangle of size of 2 * 19.9 units -- lots of unused space there.
      We get even more slack if we cut along (1,1,1,1 ...) and (1,-1,1,-1 ...) -- we get a square of size 14.1 * 14.1 units.

    Another fun one is "without loss of generality". I can't count how many times these words stopped me for quite a few minutes while I tried to understand why and make sure it really is... The revelation was usually fun. Not for obvious cases of course, but some authors can make the word "clearly" work VERY hard.

    The small volume of hyperspheres can also be understood in a Geometric way with sections:
    think of the 2d and 3d case:
    If you slice the 3d box in half and look at the section you will see exactly the 2d case, with the same proportion of ball and empty space.
    But every other parallel slice will have less ball and way more empty space! So it's kinda obvious that the volume of the 3d ball is less, it would have to be a cylinder to be equal!
    This extends to higher dimension by taking higher-1 dimensional slices.
    Of course the algebraic phrasing is more precise.
    Also some may think that this slice thing is cheating since you can't visualize that either: well, topologists and geometers are not superhumans and have developed lots of tools such as this to think about higher dimensions, and I think that all those tools deserve to be regarded as Geometrical thinking.

      Hey! I know this is really late, but I tried the simpler version of the puzzle (x1 + x2 + x3 + ... < 1) and I got sqrt(e) as the answer. Is that correct?

      @@khandanish2004 Hi! I think you made a mistake, it looks to me like you've considered the volume of the cross polytope in 2n-dimension to be 2^n/n!, while it is 2^2n / (2n)!.
      Remember, in the original puzzle we only end up working in even dimension.

      @@99Megaluca99 My intuition was even simpler: Look at the relation between a square and a circle thus: You get the circle by smoothing out the corners of the square. If you approach higher dimensions you get 2 to the power of dimension verteces (=corners), therefore we should have exponentially more corners to cut as wonder into higher dimensions.

      Okay, maybe not simpler, but an intuition nontheless. This ultimately shows as well, when you think about how you produce one higher-dimension ball: You spin it around an axle that is perpendicular to the dimensional set that contains our ball.

    I'm just mindblown by the fact that the volume of spheres "picks up" some extra pies as they increase dimensions. It's so weird! Maybe there's an interesting reason for it that you could explain in a video!

      While I definitely don't have an answer, I'd check out 3Blue1Brown's "Why is pi here? And why is it squared?" It has a really nice explanation why a pi squared can show up. Maybe that same chain of logic can start to be applied here.

      I'm not sure if this is the right explanation, but IIRC, there are two independent axes of rotation in 4D space. Assuming n-space has floor(n/2) independent axes of rotation, then I think every other integral would be bounded by [0, 2π]...? It's been a long time since I did any calculus

      If you look up the formula for the volume of a torus (donut) in 3D space, it also has a pi^2. Because you can kind of think of there being two circles going on in a torus, the radial one and the cross sectional one. And then its volume is the area of the middle circle swept around in another circle. And then yes, as Okuno above me said, in 4-d space you can also have these two independent circles (say two coming from the first two coordinates and two coming from the second two) and so in some sense it makes sense that when integrating and multiplying stacks of circles to get volumes you get two factors of pi.
