Question

The first paper by Iris Runge (“RUN-guh”) was a collaboration with this physicist that included a predecessor of the WKB method. This physicist was succeeded by the pro-Nazi professor Wilhelm Müller shortly before he published his classic six-volume Lectures on Theoretical Physics. A so-called “Bible” for 1920s quantum physicists was this scientist’s textbook Atomic Structure (-5[1])and Spectral Lines. This physicist received a record 84 nominations for the Nobel Prize in Physics without winning. (10[1])At Munich, this physicist’s PhD students included Peter Debye (“deh-BYE”), Wolfgang Pauli, and Werner Heisenberg. (10[1]-5[1])This physicist, who introduced the (-5[1])fine-structure constant (-5[1])in an update of a (10[1])model that also added elliptical (10[1])quantized (10[1])electron orbits, (-5[1])co-names the free-electron gas model with Paul Drude (10[2])(“DROO-duh”). For 10 points, (-5[1])what German physicist extended the Bohr (10[1]-5[1])model (-5[1])of the atom? ■END■ (10[5]0[10])

ANSWER: Arnold Sommerfeld [or Arnold Johannes Wilhelm Sommerfeld; accept Bohr–Sommerfeld model; accept Drude–Sommerfeld model]
