Nuclear power can often inspire thoughts of wanton destruction. I know it did for me. My grandparents, who lived through World War II, used to tell me stories about the devastation at Nagasaki and Hiroshima. I considered nuclear weapons to be humanity’s worst invention, a characterization I carried over to nuclear power. Because I had such a bad image of nuclear weapons, nuclear power, to me, was the most dangerous energy source on the planet. But all that has started to change recently as I have begun to read my supervisor James Hansen’s papers.
