The Wave Function
The mathematical object that captures everything knowable about a quantum system; its squared magnitude gives the probability of finding a particle in a given state. Wave functions underlie the discrete energy levels of atoms — and therefore the spectral lines that let astronomers read the composition, temperature, and motion of distant stars and gas.
