Generalization of Einstein's E=mc2

The first chapter of book deals with contributions of Aristotle, Galileo and Newton in development of science. Then very important issue i.e. law of conservation of matter is discussed in view of Einstein’s E=mc2. Einstein has given this famous equation in his 1905 paper and its mathematical derivation is critically analyzed. Then it logically discussed that the equation must be generalized as form of ΔE=Ac2Δm. Then ΔE=Ac2Δm is justified with help of various examples. The most important application of equation is creation of mass before Big Bang.
