    2:47 I was going to ask what happens when you start from a point in the largest empty region, but then realized that wasn't what I wanted. What I wanted was to examine what happens when you pick a point such that the resulting mid-point to a vertex was in one of the empty regions. But, it seems that you can start from such a point, but the midpoints will eventually converge on denser regions.

Oh yeah, and my "initial condition" used random points for the vertices of the triangle, with some constraint to get a "reasonable" triangle, so each run was unique. It's crazy to think about how much programming has changed in 40 years.

      @@MathVisualProofs I don't remember specifics, but it must have been BASIC. I also remember writing a (2D) graphing program a year or two later, inspired by one of my community college professors. I remember that this program involved some really intricate PEEKing and POKEing, which is why I'm pretty sure it was in BASIC. It took a lot of trial and error as I recall, but I ultimately got it to work and I remember being so stoked!

    Nice! BTW if you subdivide a cube into eight sub-cubes and repeat this process (octree) but each time removing the sub-cubes intersected by the main diagonal vector (1,1,1) the resulting structure contains a Sierpinski triangle (as can be seen when cutting through this 3d structure along a plane orthogonal to the main diagonal).

  • @kyh148
    @kyh148 ปีที่แล้ว +12

    I believe the one with Pascal's triangle is because of addition of even and uneven numbers.
    Adding two even or two uneven numbers creates an even number, while adding an even and an uneven number creates an uneven number.
    The triangle starts with a single 1, then two 1s side by side. The third layer however has an even number because there are two uneven numbers above it. Because it's now uneven-even-uneven, it generates a full row of unevens below it because there are no evens or unevens side by side. This then creates a row of evens with unevens at the side (keep in mind the outside is always uneven because it's always 1).
    The rows of unevens at the sides grow while the row with evens shrink, because at the border between the evens and unevens, an uneven appears. This converges into a triangle until the row of evens shrinks completely. Meanwhile, at the sides, because the rows of unevens grow, there are new evens generated which then turn into unevens again because they border unevens. At some point, all of the (triangular) "holes" converge again to create a full row of unevens. This in turn creates a larger row of evens which converges to a larger triangle while at the sides new triangles are continuously created. This repeats simultaneously and infinitely, so it eventually turns into an approximation of Sierpinski's triangle.
    Mathematics is beautiful.

    But if you choose the exact midpoint of the triangle as your first point, then no matter which point of the triangle you draw a line to, the midpoint of that line is not part of the Sierpinski triangle. Or does the initial point also have to be in the Sierpinski triangle?

    Yes, two more ways
    1. Conway's game of life
    We are in an infinite square grid and we can decide a square is alive or dead. A cell only has eight possible neighbours, its alive if it has two or three alive neighbours and dies if it only has one alive neighbour or more than three alive neighbours. We make a straight line that has the number of squares from the power of 2 (4097 is fine). When we simulate it, it makes a chaotic Sierpinski.
    You can search it if you dont understand it much and its a simulation called Cellular Automaton
    2. Wolfram Cellular Automata
    We are on an infinite white square grid we always start with one black square. We need to add rules to simulate if its three neighbouring squares on the bottom should be black or white by setting a table in binary descending like this
    111 110 101 100 011 010 001
    =0 =0 =0 =1 =0 =0 =1
    000 < Input
    =0 < Output
    This is called Rule 18. It gets its name from the outputs
    00010010 which is 18 in binary.
    Since we have our rule it grows like this
    Rule 18:
    1
    101
    10001
    1010101
    100000001
    10100000101
    1000100010001
    101010101010101
    You get the idea. Also, The ones represent the black squares and the zeros represent the white squares. The blank spaces are zeros too.
    There are many rules too that generate the Sierpinski like Rule 90, Rule 129 and etc
    Edit: wait so are you going to do now Visual Proofs?

  • @drdca8263
    @drdca8263 ปีที่แล้ว

    The bitwise dominance thing is, I think, basically the same as the pascal triangle one, in the following way: the pascal triangle gives the binomial coefficients. If one takes a prime number p (in this example, pick p=2) and expresses n and k in base p, then the binomial coefficient (n choose k), will be equivalent mod p, to the product of the binomial coefficients of the respective base-p digits.
    And, for p=2, this product is 1 if all the terms in the product are 1, and is 0 otherwise.
    And, (0 choose 0), (1 choose 0, and (1 choose 1) are all 1, with only (0 choose 1) being 0,
    and so the “binary digit dominance” thing ends up being whether the corresponding binomial coefficient is even or odd,
    So that’s why it gives the same thing as previous process.

    • @MathVisualProofs
      @MathVisualProofs  ปีที่แล้ว +1

      yes. they are equivalent via Lucas' theorem (as you note :) ). But they are different in general because if you perform the similar task for different bases, you don't always get Pascal's triangle mod b (you do if you mod out by primes, but not composites).

    The Sierpiński Triangle: The Sierpiński triangle is created through an iterative algorithm. Starting
    with an equilateral triangle, the midpoints of each side are found and connected
    to form an inverted smaller triangle which is then removed. The same process is
    then applied to the remaining triangles at each stage.
