...little symbol e representing a quantum began seriously to restrict the old free & easy mechanics. Nevertheless the work of reconciliation began. Denmark's Niels Bohr ingeniously yoked classical laws and quantum laws to predict the probable interorbital jumps of electrons. His famed Correspondence Principle was postulated in 1913, was later abandoned when it was found not to work for atoms having more than one electron...
...mica is in effect a photo-electric cell flattened out and each particle is a tiny photocell in itself. When lights and shadows of any scene fall upon those particles, the light waves set up a positive electro-magnetic tension in the particles. The oscillating cathode beam of electrons discharge that positive tension. Thus each particle is alternately charged by light waves and discharged by the electron beam 24 times a second, which is a comfortable frequency of illumination for the human...
...receiver of this radio system Dr. Zworykin calls a kinescope. It looks like the iconoscope. In the tube's neck is an oscillating cathode tube which weaves a pulsating beam of electrons over a fluorescent screen. Under the electron impacts the screen glows and thus shows the original iconoscoped scene...
...useful description of the atom, first pointed to Professor Einstein's relativity laws which say that we can never measure absolute time. Next he referred to Professor Werner Heisenberg's proof that we cannot measure at the same instant both the speed and the position of an electron, that the more exactly we determine the speed of electrons in an atom the less certain we can be of the position of the electrons in an atom. Thus, we can never say precisely what is Cause or what is Effect. The Heisenberg concept of uncertainty is only six years...
...uncertainty are absolute facts, reasoned Theorist Bohr in effect. Through them mathematicians are able to describe the tremendous, strange activities within an atom. But only one kind of activity at a time. For, the essential nature of atomic (or quantum) mechanics is duality. You can determine where an electron is or how fast it is moving, but not both facts simultaneously...
