There are no physicists in the hottest

There are no physicists in the hottest parts of hell, because the existence of a ‘hottest part’ implies a temperature difference, and any marginally competent physicist would immediately use this to run a heat engine and make some other part of hell comfortably cool.  This is obviously impossible.  ~Richard Davisson

Physics is mathematical not because we know

Physics is mathematical not because we know so much about the physical world, but because we know so little; it is only its mathematical properties that we can discover.  ~Bertrand Russell, quoted by Arthur Koestler, The Sleepwalkers, 1965, ECQ; and in The World within the World by John D. Barrow, 1988, CD
