On July 16, 1945, the world changed forever. That day, the American army conducted a nuclear test code-named "Trinity," which produced the first-ever nuclear detonation.
Robert Oppenheimer, the so-called "father of the atomic bomb," described his state of mind following the explosion, later saying:
"We knew the world would not be the same... I remembered the line from the Hindu scripture, the Bhagavad Gita: 'Now I am become Death, the destroyer of worlds.' I suppose we all thought that, one way or another."
