Quote

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, 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.”

― J. Robert Oppenheimer
