A generalization of his most famous statement relates the variances of two observables to the square of the expected value of their commutator.
This scientist used his knowledge of Greek to suggest the name of the meson to Hideki Yukawa to replace the etymologically suspect "mesotron." This man names a quantum mechanical generalization of the Ising model that uses Pauli matrices to describe interacting spins. He also names an approach in which observables evolve in time and state kets are fixed, called his namesake (*) "picture" of quantum mechanics. A generalization of his most famous statement relates the variances of two observables to the square of the expected value of their commutator. This man invented a system of nonÂ­commuting observables that accurately predicted the spectral lines of hydrogen and came out one year before Schrodinger's equivalent wavefunction formalism. For 10 points, name this German physicist who invented matrix mechanics and an uncertainty principle.
