Atoms
In this particular aspect we will discuss the most important prospective of origin, “atoms”. We are all made of same kinds of atoms. These atoms cycle from person to person as we breathe and as our perspiration is vaporized. Atoms are thus recyclable. Our brain may be made of atoms that were once part of Albert Einstein and of Charlie Chaplin. Just as dots of light of only three colours combine to form almost every conceivable colour on T.V. screen, only about 100 distinct kinds of atoms combine to form all the materials in this universe.
The structure of matter that shapes the world around us has been a subject of studying since long. The first contribution came from Dalton, who postulated that matter is made of atoms, which are indivisible. J.J. Thomson proposed a structure for the atom, which was modified by Rutherford and later by Niels Bohr. In this aspect, we shall also study some fundamental information about the atomic world. The phenomenon of ‘radioactivity’ has probably played the most important significant role in the development of both the atomic and nuclear physics. We shall study important aspects of this phenomenon. Further, nuclear reactions provide useful information regarding interactions of nuclei. This led us to the phenomena of nuclear fission and nuclear fusion whereby the vast reservoirs of nuclear energy were discovered.
