The development of the quantum-mechanical electron theory of metals

... mathematical methods to a wide variety of physical problems. Unlike Heisenberg and Pauli, he appears as a rule to have been more interested in the mathematical solution of a problem than in its underlying physics. In 1906, Sommerfeld had been called from the chair he held at the Technische Hochschul ...

The first two and a half years marked the childhood of the theory, after which period it entered a new and more mature phase increasingly influenced by Sommerfeld and other ...

In fact, although the forces binding atoms together in molecules cannot be properly understood without quantum mechanics, many of these forces are "short range" electrical forces - forces between bodies having overall electrical neutrality, but distorted charge distributions. These forces could defi ...

... Applied Physics and Materials Science Group, Engineering Quad, Princeton Univ., Princeton 08544 (Dated: January 5, 2008) It is generally believed that the old quantum theory, as presented by Niels Bohr in 1913, fails when applied to few electron systems, such as the H2 molecule. Here we review recen ...

... Between 1890 and about 1910, physics experienced a complete change of paradigms: Rydberg’s line spectra [1], the fascination of experiments with ‘Röntgen’s rays’ [2], and of course Rutherford’s radiation phenomena [3,4] (the birth of nuclear physics) had set the stage for a new age in science. Novel ...

Copenhagen (play)

Copenhagen is a play by Michael Frayn, based around an event that occurred in Copenhagen in 1941, a meeting between the physicists Niels Bohr and Werner Heisenberg. It premiered in London in 1998 at the National Theatre, running for more than 300 performances, starring David Burke (Niels Bohr), Sara Kestelman (Margrethe Bohr), and Matthew Marsh (Werner Heisenberg).It opened on Broadway at the Royale Theatre on 11 April 2000 and ran for 326 performances. Directed by Michael Blakemore, it starred Philip Bosco (Niels Bohr), Michael Cumpsty (Werner Heisenberg), and Blair Brown (Margrethe Bohr). It won the Tony Award for Best Play, Best Featured Actress in a Play, Blair Brown, and Best Direction of a Play (Michael Blakemore).In 2002, the play was adapted as a film by Howard Davies, produced by the BBC and presented on the Public Broadcasting Service (PBS) in the United States.
