H-Bomb History leading to the creation of the atomic bomb Atomic science began many centuries ago with experimenting and probing into the nature and structure of matter. This began with ancient philosophers and alchemists. Science began emerging with Thales of Miletus BCthe Ionian Greek, who described the power of attraction in electricity long before electricity was known.
They discussed the post-war order and peace treaty issues. America had the bomb. When Harry Truman learned of the success of the Manhattan Project, he knew he was faced with a decision of unprecedented gravity.
The capacity to end the war with Japan was in his hands, but it would involve unleashing the most terrible weapon ever known. American soldiers and civilians were weary from four years of war, yet the Japanese military was refusing to give up their fight.

For Truman, the choice whether or not to use the atomic bomb was the most difficult decision of his life.
First, an Allied demand for an immediate unconditional surrender was made to the leadership in Japan. Although the demand stated that refusal would result in total destruction, no mention of any new weapons of mass destruction was made.
The Japanese military command rejected the request for unconditional surrender, but there were indications that a conditional surrender was possible. Regardless, on August 6,a plane called the Enola Gay dropped an atomic bomb on the city of Hiroshima.
Instantly, 70, Japanese citizens were vaporized. In the months and years that followed, an additionalperished from burns and radiation sickness.
Exploding directly over a city of , the bomb vaporized over 70, people instantly and caused fires over two miles away. Two days later, the Soviet Union declared war on Japan.
On August 9, a second atomic bomb was dropped on Nagasaki, where 80, Japanese people perished. On August 14,the Japanese surrendered. Critics have charged that Truman's decision was a barbaric act that brought negative long-term consequences to the United States. A new age of nuclear terror led to a dangerous arms race.
Some military analysts insist that Japan was on its knees and the bombings were simply unnecessary. The American government was accused of racism on the grounds that such a device would never have been used against white civilians.
On August 6, the city of Hiroshima, Japan remembers those who lost their lives when the atomic bomb fell. Thousands attend the Hiroshima Peace Memorial Ceremony annually.

The Soviet Union had entered the war against Japan, and the atomic bomb could be read as a strong message for the Soviets to tread lightly.
Regardless, the United States remains the only nation in the world to have used a nuclear weapon on another nation.During World War II, American physicists and engineers began a race against Nazi Germany to develop the first atomic bomb.
Their secret endeavor, which lasted from to , was known as the Manhattan Project. The project led to the invention of nuclear weapons, including two . On August 9, a second atomic bomb was dropped on Nagasaki, where 80, Japanese people perished. On August 14, , the Japanese surrendered.
Critics have charged that Truman's decision was a barbaric act that brought negative long-term consequences to the United States. This website was created for students, educators, and the general public to understand the science, history and consequences of the atomic age.
