At very small scales, particles are described by wavefunctions that obey the Schrödinger Equation. What do wavefunctions look like?
The Wavefiz is a nifty visualizer that draws them! It's real physics: we're solving the Schrödinger Equation in real time with arbitrary potentials. But it's also just plain fun to play with!
There's some non-mathy exercises to do too. Have you heard of the ground state energy or quantum tunnelling? Those pop right out - you can see them visualized.
Surf over to the Wavefiz to see it in action!
