This is basically an introductory book on astrophysics for general readers. It takes the reader through the major developments in Physics from Aristotle and Ptolemy (science was actually philosophy in the Aristotelian Era) to modern day Physicists like Stephen Hawking and Richard Muller. The book starts from various concepts of Classical Physics, the Theory of Relativity & Quantum Physics and then comes to the topics of Astrophysics and Cosmology, which is probably the best way to understand the subject for a general reader. There is limited mathematics in this book, but some major equations are included because one cannot grasp the true 'beauty' in physics without seeing the mathematical or abstract parts alongside practical laws. Physics is to mathematics what Tony Stark (Iron Man) is to J.A.R.V.I.S. or F.R.I.D.AY. The groundwork of computations, statistics, simulations etc. is done by F.R.I.D.A.Y. But, the real work of fighting the villains is done by Iron Man!
