Inverted Quotes (2 quotes)
After seeking in vain for the construction of a perpetual motion machine, the relations were investigated which must subsist between the forces of nature if such a machine is to be impossible; and this inverted question led to the discovery of the law of the conservation of energy, which, again, explained the impossibility of perpetual motion in the sense originally intended.
Opening of Lecture (1900), 'Mathematische Probleme' (Mathematical Problems), to the International Congress of Mathematicians, Paris. From the original German reprinted in David Hilbert: Gesammelte Abhandlungen (Collected Treatises, 1970), Vol. 3.

Andrade [who was looking after wartime inventions] is like an inverted Micawber, waiting for something to turn down.
As quoted by C.P. Snow in his Lectures at Harvard University (1960), in which he spoke extensively about Henry Tizard. Collected in print as Science and Government (1960), 6. Snow gave this quote to exemplify what he called Tizard's “lively satirical tongue,” but Tizard probably did not originate the epigram. The article 'A Spectator's Notebook' The Spectator (21 Dec 1944), 4, states it was coined by Philip Guedalla, “unless, indeed, which is unlikely, it goes back farther still.” As early as during the first World War, Guedalla “applied it to the Inventions Board under Lord Fisher, sitting in an office in Cockspur Street, and ‘waiting like a kind of inverted Mr. Micawber, for something to turn down.’” Webmaster assumes Tizard's quote refers to Edward Neville da Costa Andrade, also a wartime science consultant.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
