Music that paints nothing is only noise.

An experiment, like every other event which takes place, is a natural phenomenon; but in a scientific experiment the circumstances are so arranged that the relations between a particular set of phenomena may be studied to the best advantage. James Clerk Maxwell, 1876

You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and more important, no one really knows what entropy really is, so in a debate you will always have the advantage. […]

“An engineering science aims to organize the design principles used in engineering practice into a discipline and thus to exhibit the similarities between different areas of engineering practice and to emphasize the power of fundamental concepts. In short, an engineering science is predominated by theoretical analysis and very often uses the tool of advanced mathematics.” […]

“I do not plan to come back. I have no reason to come back. I plan to do my best to help the Chinese people build up the nation to where they can live with dignity and happiness.” Qian (1955) to reporters after returning to China. Cited in: “Qian Xuesen dies at 98; rocket scientist […]

“If you say why not bomb them tomorrow, I say why not today? If you say today at five o’ clock, I say why not one o’ clock?” John von Neumann As quoted in “The Passing of a Great Mind” by Clay Blair, Jr., in LIFE Magazine (25 February 1957), p. 96

“We built airplane models with Coke bottle-shaped fuselages and lo and behold the drag of the wing just disappeared. The wind tunnel showed it worked perfectly.” Richard T. Whitcomb https://www.nasa.gov/topics/people/features/ richard_whitcomb.html

Introduction to Compressible Flow “We call the speed range just below and just above the sonic speed – Mach number nearly equal to one – the transonic range. Hugh Dryden and I invented the word transonic. We had found that a word was needed to denote the critical speed range of which we were talking. […]

“Young man, in mathematics you don’t understand things. You just get used to them.” Reply, according to Dr. Felix T. Smith of Stanford Research Institute, to a physicist friend who had said “I’m afraid I don’t understand the method of characteristics,” as quoted in The Dancing Wu Li Masters: An Overview of the New Physics […]
