A first for the general public, the picture of the “mushroom cloud”? is a very accurate approximation of the enormous quantity of energy spread below. The first atomic bomb, released on August 6 in Hiroshima(Japan) killed about 80,000 people, but it didn’t seem enough because the Japanese didn’t surrender right away. Therefore, on August 9 another bomb was released above Nagasaki. The effects of the second bomb were even more devastating – 150,000 people were killed or injured.
