The Many World Interpretation or the Copenhagen Interpretation

The Copenhagen Interpretation: This interpretation is a little bit like quantum physics’ answer to the old Zen question: If a tree falls in the woods and no one is around to hear it, does it make a ...

Electronic Wave Functions. IV. Some General Theorems for the Calculation of Schrodinger Integrals between Complicated Vector-Coupled Functions for Many-Electron Atoms

A scheme of theorems is developed which enables an important class of integrals of the Schrodinger Hamiltonian between antisymmetric vector-coupled functions of the Russell-Saunders type to be ...
