When is an intelligent man converted into scientist? The answer is simple. If an intelligent person has the habit of asking the reasons about the working of things around us and further if he has the ability to go to the base of each and everything, then very soon he reaches the origin of the working and ends up into a theorem; which further leads him to the Nobel Award. Behind every happening, there is some scientific reason. If that reason is not reached at then the happening remains a mystery. The purpose of this book is to quench the thirst of finding out the mystery at least up to certain extent.
