Energy resources serve as mediums for improving our quality of life. The nucleus of an atom is very minute, yet it can be manipulated to provide megaunits of energy to industrial plants. It can generate enough energy to launch a rocket into space and set it into orbit for an extended period of time. It can produce enough electrical power to supply an entire community, or it can produce enough force to destroy an entire country. It is increasingly becoming usefull in medicine.
Nuclear energy can be quite useful or violently destructive.
This chapter provives a basic overview of nuclear physics. The universe is inconceivably vast. No one knows its origin or the extent of its boundaries. Astronomers believe that the universe is continuously expanding due to stellar explosions within the system. The universe includes the stars, planets, satellites, comets, asteroids, the solar system, outer space, matter and energy.
