B A question about Schrödinger's equation.

[Fuinne]

Hi,

So was Schrödinger's equation basically the birth of the idea that quantum mechanical systems work off probability? Also, I'm sure it's not Heisenberg, but I'm thinking of a physicist who took the wave function Ψ(x,y,z,t) and squared the absolute value of it, and I was wondering what his name was.

Thanks, and have a nice night,

According to a note in Binney and Skinner, The Physics of Quantum Mechanics, it was Max Born who first suggested that the wave function was related to position probability:

For this insight Born won the 1954 Nobel Price for physics. In fact the text of the key paper (Born, M., Z. Physik, 37 863 (1926)) argues that ψ is the probability density, but a note in proof says “On more careful consideration, the probability is proportional to the square of ψ”.

I believe you were thinking of Born: https://en.wikipedia.org/wiki/Born_rule.
