Uber den anschaulichen Inhalt der quantentheoretischen Kinematik und Mechanik [HEISENBERG'S UNCERETAINTY PRINCIPLE], pp. 172-198 in: Zeitschrift fur Physik, volume 43
Berlin: Julius Springer, 1927. First edition, complete journal volume, of Heisenberg's Uncertainty Principle, one of the most important and celebrated discoveries in modern science. "The prevailing quantum theory in the early 1920s modeled the atom as having electrons in fixed quantized orbits around a nucleus. Electrons could move to higher or lower energy by absorbing or emitting a photon of the right wavelength. The model worked well for hydrogen, but ran into problems with larger atoms and with molecules . . . Heisenberg objected to the current model because he claimed that since one couldn't actually observe the orbit of electrons around a nucleus, such orbits couldn't really be said to exist. One could only observe the spectrum of light emitted or absorbed by atoms. Starting in 1925, Heisenberg set to work trying to come up with a quantum mechanics that relied only on properties that could, at least in theory, be observed. With help and inspiration from several colleagues, Heisenberg developed a new approach to quantum mechanics. Basically, he took quantities such as position and velocity, and found a new way to represent and manipulate them. Max Born identified the strange math in Heisenberg's method as matrices. The new formulation accounted for many observed properties of atoms . . . Shortly after Heisenberg came up with his matrix-based quantum mechanics, Erwin Schrödinger developed his wave formulation . . . Though others may have found the wave approach easier to use, Heisenberg's matrix mechanics led him naturally to the uncertainty principle for which he is we … [Click Below for Full Description]
