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.

Geometry was the first exciting course I remember.

While we cannot accurately predict the course of climate change in the coming decades, the risks we run if we don't change our course are enormous. Prudent risk management does not equate uncertainty with inaction.

Just refrigerator efficiency saves more energy than all that we're generating from renewables, excluding hydroelectric power... I cannot impress upon you how important energy efficiency is. It doesn't mean you eat lukewarm food and your beers are lukewarm. You can still have it; you just make a better thing

If I were emperor of the world, I would put the pedal to the floor on energy efficiency and conservation for the next decade.

Occasionally, I would focus on a particular school project and become obsessed with, what seemed to my mother, to be trivial details instead of apportioning the time I spent on school work in a more efficient way.
