TRINITY TEST

On Monday, July 16, 1945, at 5:29:45 a.m., the first atomic device detonated at the Trinity Test Site.
J. Robert Oppenheimer, who had directed the project, said: "We waited until the blast had passed, walked out of the shelter and then it was extremely solemn. We knew the world would not be the same. A few people laughed, a few people cried. Most people were silent.
I remembered the line from the Hindu scripture, the Bhagavad-Gita: Vishnu is trying to persuade the Prince that he should do his duty and to impress him he takes on his multi-armed form and says, 'Now I am become Death, the destroyer of worlds.' I suppose we all thought that, one way or another."
(From Richard Rhodes, "The Making of the Atomic Bomb")
