Robert Oppenheimer — "I feel we have blood on our hands."

"We have used a weapon that has changed the course of history."

"We have made a thing, a most terrible weapon, that has altered the nature of the world. We have made a thing that has made it impossible for us to live without changing our whole way of life."

"In the spring of 1936, I was introduced by friends to Jean Tatlock. In the autumn, I began to court her. We were at least twice close enough to marriage to think of ourselves as engaged."

"No man should escape our universities without knowing how little he knows."

"We have to find a way to control this weapon, or it will control us."
