If other countries don't impose a cost on carbon, then we will be at a disadvantage...we would look at considering perhaps duties that would offset that cost.

Switching to light-coloured roofs and roadways would have the equivalent effect on greenhouse gas emissions to taking one billion cars off the road for eleven years.

My physics teacher, Thomas Miner was particularly gifted. To this day, I remember how he introduced the subject of physics. He told us we were going to learn how to deal with very simple questions such as how a body falls due to the acceleration of gravity.

Science is really about describing the way the universe works in one aspect or another in all branches of science-how a life-form works, how this works, how that works. ... You have to have a natural curiosity for that.

Pick the right sized pot, don't pick a pot five times bigger, twice as big.

I approached the bulk of my schoolwork as a chore rather than an intellectual adventure. The tedium was relieved by a few courses that seem to be qualitatively different. Geometry was the first exciting course I remember. Instead of memorizing facts, we were asked to think in clear, logical steps. Beginning from a few intuitive postulates, far reaching consequences could be derived, and I took immediately to the sport of proving theorems.
