    I started watching this video, but the intro made it sound like it was a follow-up to the video on Steve's channel. So I paused and went and started watching the video on Steve's channel and he made it sound like it was a follow-up to this video. The infinite loop made my brain crash, thanks.

    This sums up why I ended up in Physics rather than maths too. I always preferred the Mathematical aspect of Physics, but because A) my organisation is an utter mess and B) I prefer the answer to the beauty I went towards Physics. Here we have Steve Mould with a "messy" sheet of working out on all directions (look OCD to mine) and Steve wanting to finish at the result rather than the beautiful simplified result.
    Its something I've noticed throughout my career, Mathematicians want utter perfection and Euler's Formula like beauty, physicists would rather take a few assumptions like sin x = x, and any simplification is to ease remembering. And that is also why Mathematical Analysis never agreed with me, a branch of Mathematics so anal as to demand a proof for "1+1=2" with a Physicist's constant reasoning "because it is" for any semi-obvious mathematical assumption. There's your answer, nobody cares why, lets get to the fun stuff.
    On a side note, I've always tended towards watching maths videos. Not sure if its because I simply prefer listening to Maths, if its because it gets difficult to find a video with enough Physics left to learn, or if its because the physics I do have left gets a little too in depth for easy watching. Either way, I could watch you two collab forever. Physicist and a mathematician, but you certainly didn't lack any chemistry. Yeah I know, women aren't funny.

      As someone who would rather just do the beautiful maths, what you said is pretty accurate 😂. Although it differs quite a bit by field. Applied mathematics like numerics and statistics can be complete abominations, while purer counterparts like analysis and stochastics are generally very pretty.
      And if everyone knows that everyone knows how you would prove something, you can leave it out as trivial. You just don't allow early semesters to do that. 😉
      I guess most mathematicians end up doing the pretty stuff for fun and the applied counterpart for fun-ding

      Parker lattices have an amazing 93% packing density... except some of the component spheres are much smaller and others are made of a very malleable clay. Matt still thinks it's pretty great, though.

    I would really love to hear about the properties of the "jumbled packagings" in higher dimensions, it is rather uinintuitive to imagine there are some that are not regular, so maybe the (prime?) properties of the actual dimension play a role in here?

    The square base is not the same as the tetrahedron on its side (though the spacing is the same) as a tetrahedron is platonic and so is the same when placed on any face. There are no Square faces, and the square base has one, so the two shapes aren't congruent.

    • @stevethecatcouch6532
      @stevethecatcouch6532 7 ปีที่แล้ว

      True, a square based pyramid is not congruent with a tetrahedron, but how is that relevant to the video?

    • @aoifebakunin1966
      @aoifebakunin1966 7 ปีที่แล้ว

      The tetrahedral arrangement has 6+3+1 or 10 spheres, the square one has 9+4+1 or 14 spheres. Take four spheres out of the square arrangement without moving any of the others and you get the tetrahedral arrangement.

  • @tcf70tyrannosapiensbonsai

    6:50 The regular pattern, Steve expected, is an icosahedron. If Matt took three red balls in the left hand with the green one on top, as he did, and the three other hands of the two Smarties would carry three red balls each, they could arrange the triplets as a tetrahedron. Et voilà, an ikosahedron with twelve corners.
    From that perspective it's hardly imaginable, that anyone considered 13 balls could ever touch the center ball.
    I really like watching the two of you educating us math and physics with such joy!

    • @Smitology

    The amount of spheres that can touch a sphere in any dimension is:

    0: 0^2 + 0 = 0
    1: 1^2 + 1 = 2
    2: 2^2 + 2 = 6

    4: 4^2 + 4 = 20

      No. For n=4, it's 24, and in higher dimensions your terms are lower than the known lower bounds. Look up "kissing number".
