New #chaos dweets

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)

    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

The chaotic sea in the phase space of the standard map on the two-torus. We observe a mixture of chains of chaotic regions, ergodic looks and stable islands. As seen on: https://www.math.uni-tuebingen.de/user/stke/… #chaos #attractor

Interesting #chaos pattern

Actually a spirograph but the big arcs aren't visible

tis nice

i just noticed i got it wrong, since in treating angular momentum as radius!! its still a chaotic map but a different kind

Amazing... It's like pseudo orbital mechanics! This inspired me to finally try something in "3D"

Been wanting to do a Lorentz system ever since I first saw Dwitter. Congrats! :)
