Wick rotating this physicist’s namesake equation gives rise to the heat equation. By assuming that Slater determinants are good approximations, the Hartree-Fock method is (10[1])used to find approximate solutions to an equation named after this physicist. Eigenfunctions of the Hamiltonian are solutions to the time-independent form of an equation named after this physicist. This physicist explored the principle of superposition in a thought experiment that uses a Geiger counter to break a vial of poison. For 10 points, name this physicist, whose namesake thought experiment involves a simultaneously dead and alive cat. ■END■
