    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.

Feigenbaum Flower. Homage to Mitchell Feigenbaum (1944-2019). He demonstrated the universal character of dynamical non-linear systems, which has made possible the systematic study of chaos. In 1975, using the small HP-65 calculator, he discovered that the ratio of successive distances between bifurcation events tends to a constant δ ≈ 4.66920... This "ratio of convergence" of period-doubling bifurcations is now known as the first Feigenbaum constant. #bifurcation #attractor #fractal #chaos #math

This is a great tribute. RIP.

really nice

Rodrigo - are you working full time on this fractal stuff? Super impressive if its only a hobby. Great work.

Lorenz Attractor in color - this will be printed and framed. #lorenz #attractor

you really like #chaos math and attractors
u/taupelink

With good reason, I think :) They are beautiful and, well, strange
u/KilledByAPixel

You should frame the code along with the image ;) Awesome work.

The prints are ready! Yes, source code is printed with images. https://twitter.com/rsiqueira/status/1143629…
