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

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.

As the saying goes, the Stone Age did not end because we ran out of stones; we transitioned to better solutions. The same opportunity lies before us with energy efficiency and clean energy.

For the better part of my last semester at Garden City High, I constructed a physical pendulum and used it to make a "precision" measurement of gravity. The years of experience building things taught me skills that were directly applicable to the construction of the pendulum. Twenty-five years later, I was to develop a refined version of this measurement using laser-cooled atoms in an atomic fountain interferometer.

At Rochester, I came with the same emotions as many of the entering freshman: everything was new, exciting and a bit overwhelming, but at least nobody had heard of my brothers and cousins.

I also developed an interest in sports, and played in informal games at a nearby school yard where the neighborhood children met to play touch football, baseball, basketball and occasionally, ice hockey.
