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. Am...
