First printing in original wrappers of all three parts of Bohr’s landmark paper marking the definitive break from using classical physics at the atomic level. In exceptionally fine condition.
’On the constitution of atoms and molecules’ was seminally important to physics. Besides proposing a useful model of the atom, it demonstrated that events that take place on the atomic scale are quantized: that just as matter exists as atoms and particles in a state of essential graininess, so also does the process. Process is discontinuous and the ‘granule’ of process- of electron motions within the atom, for example- is Plank’s constant. The older mechanistic physics was therefore imprecise; though a good approximation that worked for large-scale events, it failed to account for atomic subtleties… Bohr was happy to force this confrontation between the old physics and the new. He felt that it would be fruitful for physics. Because original work is inherently rebellious, his paper was not only an examination of the physical world but also a political ********. It proposed, in a sense, to begin a reform movement in physics… “On the constitution of atoms and molecules,” so proudly and bravely titled- Part I mailed to Rutherford on March 6, 1913, Parts II and III finished and published before the end of the year- would change the course of twentieth-century physics. Bohr won the 1922 Nobel Prize in Physics for the work” (Rhodes, The Making of the Atomic Bomb, 69-75). Only very light wear to wrapper. A magnificent copy, most rare in this condition.
