1 Complex Numbers in Quantum Mechanics
Quantum mechanics is different. Factors of i = √ −1 are everywhere, for example from Heisenberg we have his famous commutation relation, QP −PQ = i¯h, and from Schr¨odinger his equally famous equation ¯h i ∂tΨ = HΨ. The wave function Ψ is complex and so is practically every other quantity needed to formulate quantum mechanics.
