Many of the scientific achievements that we take for granted today have reached far beyond the dreams of scientists and science fiction writers of just seventy-five years ago. One of the most spectacular of these scientific accomplishments was the splitting of the atom. Life has never been the same since that event.
From microwave ovens to electrical power and nuclear medicine, to ships that can sail the seas for as long as twelve years without refueling, the atom provides a better life for many of the inhabitants of the earth. Yet, this same power that is used today to detect genetic disorders in unborn children or to destroy a malignant cancer cell was the destructive force that killed over one hundred thousand people in Hiroshima and Nagasaki at the end of World War II.
The splitting of the atom, the unleashing of its terrific power, poses the greatest single threat known to humanity. We now have the power to destroy in a matter of minutes a civilisation that has taken centuries to develop. Never before has the power for such potential good or such total destruction existed.
