Somehow we have to figure out how to boost the price of gasoline to the levels in Europe.

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.

I believe [the Department of Energy] should be judged not by the money we direct to a particular State or district, company, university or national lab, but by the character of our decisions.
