Following this test, a uranium-gun type nuclear bomb (Little Boy) was dropped on the Japanese city of Hiroshima on August 6, 1945, with a blast yield
The Making of the Atomic Bomb general authority on early nuclear weapons history, as well as the development of modern physics in general, during the first half of the 20th century. Nobel Laureate I. I. Rabi, one of the prime participants in the dawn of the atomic age, called it "an epic worthy of Milton. No where else have I seen the whole story put down with such elegance and gusto and in such revealing detail and simple language which carries the reader through wonderful and profound scientific discoveries and their application."
