This text explores the mathematical origins of the five most important scientific achievements, that have permanently altered our everyday lives. The book enables easy comprehension of the meaning of the equations, without having to settle for a non-mathematical translation. The private and public lives of the scientists who discovered them are also discussed. The five scientists and equations are, Isaac Newton's Universal law of Gravity, Daniel Bernoulli's Law of Hydro-Dynamic Pressure, Michael Farraday's Law of Electro-Magnetic Induction, Rudolf Clausius' Second Law of Thermo-Dynamics and Albert Einstein's Theory of Relativity.
