About this Item

FIRST EDITION OF THE FIRST MATHEMATICALLY CORRECT FORMULATION OF THE HEISENBERG UNCERTAINTY PRINCIPLE. In quantum mechanics, "the uncertainty principle is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle, such as position x and momentum p, can be known simultaneously. The more precisely the position of some particle is determined, the less precisely its momentum can be known and vice versa. In "Zur quantenmechanik einfacher bewegungstypen," or "Quantum mechanics of simple types of motion, Earle Kennard correctly derived the formula for uncertainty of position and momentum only a few months after Heisenberg stated his principle. While on a sabbatical from Cornell and at the University of Gottingen in 1926, Kennard had learned the new quantum mechanics directly from Heisenberg and Jordan. With that knowledge and his deep understanding of Heisenberg's work, Kennard was able to derive "the first rigorous form of the uncertainty principle and fully solved several simple quantum mechanics problems for the first time" (Wikipedia). ALSO IN THIS VOLUME: "Wechselwirkung neutraler Atome und homöopolare Bindung nach der Quantenmechanik" by Walter Heitler and Fritz London (pp. 455-473), the first application of wave mechanics to the theory of chemical bonding.
