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).

is this real life?

i feel like this tweet, by itself, might be the case to expand dwitter to 240

Real life in what way?
