Kinda like the I Ching..........an ancient Chinese text.........halving lines......breaking lines..........kinda like sieving...............................2 is a simple sieve..........the 1st one..........the 1st sieve is 2........words into math......1/2................




Cantor Dust

DOWNLOAD Mathematica Notebook CantorDustFractalCantor dust is a fractal that can be constructed using string rewriting beginning with a cell [0] and iterating the rules
 {0->[0 0 0; 0 0 0; 0 0 0],1->[1 0 1; 0 0 0; 1 0 1]}.
(1)
The nth iteration of Cantor dust is implemented in the Wolfram Language as CantorMesh[n, 2].
Let N_n be the number of black boxes, L_n the length of a side of a box, and A_n the fractional area of black boxes after the nth iteration, then
N_n=4^n
(2)
L_n=3^(-n)
(3)
A_n=L_n^2N_n
(4)
=(4/9)^n.
(5)
The number of black squares after n=0, 1, 2, ... iterations is therefore 1, 4, 16, 64, 256, 1024, 4096, 16384, ... (OEIS A000302). The capacity dimension is therefore
d_(cap)=-lim_(n->infty)(lnN_n)/(lnL_n)
(6)
=log_34
(7)
=(2ln2)/(ln3)
(8)
=1.261859.
