In existographies, Max Planck (97-8 BE) (1858-1947 ACM) (IQ:180|#120) (RGM:23|1,350+) (Gottlieb 1000:25) (Becker 160:20|8L) (Simmons 100:25) (Odueny 100:15) (Kanowitz 50:8) (GPE:17) (PR:265|65AE / physicist:7) (CR:254) (LH:9) (TL:267|31) was a German physicist, noted for []


The following are quotes:

Entropy depends on disorder and this disorder, according to the electromagnetic theory of radiation for the monochromatic vibrations of a resonator when situated in a permanent stationary radiation field, depends on the irregularity with which it constantly changes its amplitude and phase, provided one considers time intervals large compared to the time of one vibration but small compared to the duration of a measurement. If amplitude and phase both remained absolutely constant, which means completely homogeneous vibrations, no entropy could exist and the vibrational energy would have to be completely free to be converted into work.”
— Max Planck (1901), “On the Law of Distribution of Energy in the Normal Spectrum” [1]
“Here, manifestly, the bridge of understanding is supplied. The micro-observer needs only to assimilate in his theory the physical hypothesis that all those special cases in which special exceptional conditions exist among the neighboring configurations of interacting atoms do not occur in nature, or, in other words, that the micro-states are in elementary disorder. Then the uniqueness of the macroscopic process is assured and with it, also, the fulfillment of the principle of increase of entropy in all directions. Therefore, it is not the atomic distribution, but rather the hypothesis of elementary disorder, which forms the real kernel of the principle of increase of entropy and, therefore, the preliminary condition for the existence of entropy.”

“My studies of entropy, which I regarded as next to energy the most important property of physical systems. Since its maximum value indicates a state of equilibrium, all the laws of physical and chemical systems follow from a knowledge of entropy.”
— Max Planck (c.1947), Scientific Autobiography (pgs. 19-20) [3]
