Regarding heat exchange:

"My desk on which I now write, and the lock of my desk, are both exposed to the same temperature of the air, and have therefore the same degree of heat or cold; yet if I lay  my hand successively on the wood and on the metal, the later feels much the coldest, not that it is really so, but being a better conductor, it more readily than the wood takes away and draws into itself the fire that was in my skin." - Benjamin Franklin, early Americal statesman, inventor, printer, and scientist.

Regarding wind:

"Great whirls have little whirls
That feed on their velocity;
And little whirls have lesser whirls,
And so on to viscosity."
  - L.F. Richardson (responsible for
    much of the theory of atmospheric
    turbulence)
