Quantum mechanic's most iconic image: the cat who is both death and alive at the same moment. "In quantum mechanics, Schrödinger's cat is a thought experiment that illustrates a paradox of quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead as a result of its fate being linked to a random subatomic event that may or may not occur. This thought experiment was devised by physicist Erwin Schrödinger in 1935, in a discussion with Albert Einstein, to illustrate what Schrödinger saw as the problems of the Copenhagen interpretation of quantum mechanics. The scenario is often featured in theoretical discussions of the interpretations of quantum mechanics, particularly in situations involving the measurement problem" (Wikipedia). The Austrian-Irish physicist Erwin Rudolf Josef Alexander Schrödinger (1887-1861) called his thought experiment a "ganz burleske Fälle" [p. 812]. Published in three parts; all contained in the entire volume [xix, 870 pp.; many illustrations] of this scientific weekly, edited by H. Matthée, with important and ground-breaking publications by a who's who in physics: Wolfgang Pauli, Otto Hahn, Lise Meitler, P. Debye, Niels Bohr, Werner Heisenberg, Max von Laue, and many others, includes some very important publications on Uranium and nuclear fission. Debye and Hahn were two of the ten co-editors of this volume. Other subjects are also physical, chemical, biological, etc. Usually found with ex library signs, this however, is a rare, clean, unmarked copy.
