"When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science. "
William Thomson, Lord Kelvin, Popular Lectures and Addresses [1891-1894]

Gathering of "quotes", let's see how many we get before permanent head damage.

"There is nothing wrong in having a strong opinion but its utter foolishness to have a fixed opinion."

Self-authored 'quotable quotes' from a staff member in the department:

"Confident optimism is the mother's milk of winners."

I saw 2 mauled animals today while driving to work. I'm sad.

One was a bird and the other was a bunny. They were run over by vehicles and were lying in the middle of the road.

The bird was just squashed, but the bunny had been eviscerated and lying in a red smear.

At least I didn't run over them. But I hope someone picks them up soon.
