Hermann von Helmholtz

The older view of the nature of heat was that it is a substance, very fine and imponderable indeed, but indestructible, and unchangeable in quantity, which is an essential fundamental property of all matter.

What appeared to the earlier physicists to be the constant quantity of heat is nothing more than the whole motive power of the motion of heat, which remains constant so long as it is not transformed into other forms of work, or results afresh from them.

I have friends of mine that are actors or singers, and they're the classic guys where, they're onstage, and they're like, 'Okay, the blonde in the third row, seat 24, bring her to my dressing room.' I've never, never taken advantage of that, I swear to God.

My grandma actually put me in girdles when I was around nine or ten because I had hips even then, and she didn't want boys to be attracted to me. Having hips meant you were a full-grown woman, and I was too young for that.

For a boy of ten, used to the coal bings and rust-coloured burns of Cowdenbeath, the fields and woodland of Kingswood, with its overgrown but stately avenue of copper-barked sequoias, felt like a local version of paradise.
