For 10 points, name this Danish physicist whose model of the atom held that electrons travel in orbits around the nucleus.
Electron magnetic dipole moment is often measured in units of this scientist's namesake magneton. This scientist formulated the correspondence principle and devised the idea of complementarity. Along with Heisenberg, he helped develop the Copenhagen interpretation of quantum mechanics.
