I entered here through Chaos. The beauty of determinism without prediction. Yes, Julia sets and Mandelbrot sets were beautiful too – even more beautiful when I could replicate them with my first attempt at basic programming. But, it was really determinism and, on principle, impossible precise prediction (but, of course, at times broad patterns) that got me. And, then I have not done enough with this. Side tracket.
But, I put up this page from Virtual Labs anyway. In case I find the time to go back to that first love.
