Everybody said Dad was a genius. He was an expert in math and physics and electricity

He read books on calculus and logarithmic algebra and loved what he called the poetry and symmetry of math. He told us about the magic qualities every number has and how numbers unlock the secrets of the universe. But Dad s main interest was energy: thermal energy, nuclear energy, solar energy, electrical energy, and energy from the wind. He said there were so many untapped sources of energy in the world that it was ridiculous to be burning all that fossil fuel.
