    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.

Smoler Impossible Marble #Physics

u/tomxor

-11 bytes: Eliminated the intermediate k, moved some coefficients around, and swapped hypot for square values which is actually more stable for intersection resolution. Now it will never stop jiggling :D
u/magna

WOW!
u/pavel

Currently traced pixel is part of the ball and part of the background therefore collision. Awesome trick. My first time seeing this.

Schrodinger Equation Particle Probability Plot for a 3D Infinite Square Well

u/jdspugh

You can change the numbers in p=S(3*u/d)*S(2*v/d)*S(2*z/d) to see the different harmonics.
u/jdspugh

You can also see animated cross-sections by modifying to p=S(3*u/d)*S(2*v/d)*S(2*z/d+t).
u/donbright

Real life in what way?
