We knew that the world would never be the same. A few people laughed, a few people cried. Most were silent. I remembered a line from Hinduism's holy book, the Bhagavad Gita; Vishnu tries to persuade the Prince that he must do his duty, and, in order to impress him, takes on his many-armed form and says: “I am Death, the great destroyer of worlds...” These words were spoken by Robert Oppenheimer after nuclear bombs wiped out the Earth. Hiroshima and Nagasaki. Two bombs, named "Little Boy" and "Fat Man", were the result of the long-term work of the Manhattan Project. A group of the world's best scientists, led by Robert Oppenheimer, worked for several years to create the most powerful and dangerous weapon in the world. Articles dedicated to the work of the Manhattan Project made up the book you are holding in your hands.
