The Atomic Bomb in World War Two
In 1941 the Japanese attacked Pearl Harbor, the armed forces of the United States and her allies had been at war with Japan. The combined land, sea and air forces of the allied forces fought back against Japan, until only the Japanese homeland remained in Japanese control. On July 26,1941 President Truman issued the Potsdam Declaration,which called for Japan’s unconditional surrender and listed peace terms. The Japanese were warned of the consequences of continued resistance by the terms of the Potsdam Declaration, signed by President Truman, the Prime Minister of the United Kingdom with concurrence of Chang Kai-Shek, President of the National Government of China. When
Japan rejected the ultimatum the Untied States unleashed the fury of the most powerful destructive force known to man the Atomic Bomb. The bombing of Hiroshima and Nagasaki was not necessary.
Atomic science began many centuries ago with ancient philosophers and alchemists experimenting and probing into the nature and structure of matter. Science began emerging when Thales of Miletus, the Ioian Greek in (634-546 BC) described the power of attraction in electricity long before electricity was known. In (460-370 BC) a Greek philosopher named Demoncritus was called the “father of the atom”. Although he had no experimental evidence to support himself, Demoncritus argued that all matter must consist of a number of fundamental pieces. He called these pieces “atoms” from the Greek word “atomon” which means indivisible. In (79 BC), the Roman poet-philosopher Titus Lucretius developed atomic theory. After the fall of the Roman Empire and
throughout the middle ages the theory of the atomic view of matter was almost lost. Then the seventeenth century brought the age of Galilo, through his observations of falling objects and controlled experiments was regarded as the father of modern physics. Around 1803 John Dalton, an English chemist developed the first useful atomic theory of matter. Amedeo Avogadro, the Italian chemist in 1811 published an article drawing the distinction between the atom and the molecule, which now is known as “Avogadro’s
Principle”. The French team of Pierre and Marie Curie who are known as the parents of nuclear physics came to the realization that the atom has a core, or nucleus. It became apparent that different laws of physics govern the nucleus. In Cambridge England, Sir J.J. Thomson who in 1897 discovered the electron and his pupil Lord Ernest Rutherford discovered the proton. The history of the atomic age was coming right along on a steady pace then in 1905 Albert Einstein wrote the mass-energy conversion equation, and things started to progress very rapidly. In 1932 Sir James Chadwick discovered the neutron, this rovided an ideal projectile for splitting the atom. The final clue to the neutron and atomic energy was when an observation was noted that a peculiar property of the radiation emitted when beryllium is...
