NUCLEAR ENERGY

Nuclear energy is the energy contained in the nucleus or center of an atom. It is the most powerful form of energy that exists. Only in this century have scientists learned how to obtain nuclear energy. They have put it to obtain nuclear energy. They have put it to constructive uses, as in electric power stations. They have also put it to destructive uses, as in the atomic bomb and hydrogen bomb.

Sometimes nuclear energy is called atomic energy because it is obtained from atoms. This is not a good choice of words. Other forms of energy can also be obtained from atoms. For example, chemical energy, also, comes from atoms. But it comes from reactions outside the atomic nuclei (nuclei is the plural of nucleus). Chemical energy is released when coal, oil, gas, and other fuels are burned. This article uses the more accurate term nuclear energy for the energy obtained from the nucleus of an atom.

Why did scientists begin to study nuclear energy? They did not know when they began, that this energy could be controlled and made into useful form of power. Neither did they know how important the threat of nuclear war would become in international affairs.

Scientist began to study nuclear energy for the same reasons that most scientific studies are begun. They were curious about the nature of the universe. They wanted to understand the laws by which the universe works. Most of the important scientific discoveries made throughout history have been made for these reasons. But there are practical results as well. The more knowledge men have about the laws of the universe, the more they can control the world they live in.
