NUCLEAR WEAPONS
NUCLEAR WEAPONS: The Nuclear Weapon is defined as an explosive device which releases tremendous energy by the process of a nuclear reaction which could be nuclear fission or fusion or both. It would have been better,had I had written this article as a nuclear physicist,had my mathematical formula of Pi was in school textbooks and had my talents harnessed for making the world a better place to live in.Anyway,I will still attempt as an ordinary doctor with monthly salary of rupees 25000 only… There are various naturally occurring forces in the universe like gravitational forces,electromagnetic forces,nuclear forces etc etc.Nuclear forces bind protons and neutrons in the nucleas of any atom.It is the breakdown of these nuclear forces with resultant loss of mass which releases tremendous energy which can be used in a nuclear reactor to produce electricity or can be used in nuclear weapons to destroy human beings and infrastructure.

THE COMPUTER AND INTERNET
THE COMPUTER AND THE INTERNET: Prologue: Millions of people read my comments on internet and yet,majority of them have very little knowledge of computer/internet and hence I am posting this comments to educate them. Today,we live in computer age,the computers are found everywhere and it has created global awareness. Computer is defined as a programmable machine that computes(stores,processes and retrieves) information(data)according to a set of instructions(program). Church-Tuning theory of mathematical versatility suggests that any computer with certain minimum capacity,in principle, can perform the same task that any other computer can perform. Computers are of 2 kinds,analog and digital. Analog computer is slower,having continuous inputs and uses mechanical devices like gear/rachet/lever to perform mathematical task, for example,speedometer in a car or electricity meter in house etc.It translates variables in a given problem into analogous variations in electrical quantity like current/voltage and solve original problem by solving an equivalent problem(analog) in electrical […]
