Packet 1: Bonus 17
The second-order terms of Moyal’s and this scientist’s namesake Taylor expansion of the master equations are used to derive the Fokker–Planck equation. For 10 points each:
[10m] Name this Dutch physicist whose degeneracy theorem applies to time-reversible systems with half-integer spin. Along with Wentzel and Brillouin (“bree-WANN”), this physicist names a method often used to solve the Schrödinger equation.
ANSWER: Hans Kramers [or Hendrik Anthony Kramers]
[10h] Phillip Anderson improved Kramers’ model of this interaction, which he had first observed in manganese(II) oxide. The Goodenough–Kanamori rules semi-empirically describe this interaction.
ANSWER: superexchange [or Kramers–Anderson superexchange; prompt on exchange]
[10e] Prior to quantum mechanics, Kramers and this physicist modeled photon dispersion by electrons. This German physicist names a lower bound on the combined precision of two canonically conjugate variables.
ANSWER: Werner Heisenberg [or Werner Karl Heisenberg]
