... 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.

RePoSS #9: The Early Reception of Bohr`s Atomic Theory (1913
... that time Bohr’s original theory was widely recognized and on its way to be
further developed into the Bohr-Sommerfeld theory. 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

Evolution of the Atomic Concept and the Beginnings of Modern
... 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 ...

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 ...

made up the energy difference. Bohr’s model accounted for the stability of atoms
(the electron orbits were stable states that did not radiate) and for spectral lines (as

Niels Bohr and the dawn of quantum theory
... Between 1890 and about 1910, physics experienced a complete change of paradigms:
Rydberg’s line spectra , the fascination of experiments with ‘Röntgen’s rays’ , 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 ...

... Niels Bohr, in 1913, set forth that the elementary quantum of

emission of light from a black-body, should also be necessary to ensure
matter stability. His atomic model was probably one of the most
intriguing and fruitful conc ...

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.
