Truth and Beauty [EPUB ebook] 
Aesthetics and Motivations in Science

"What a splendid book! Reading it is a joy, and for me, at least, continuing reading it became compulsive. . . . Chandrasekhar is a distinguished astrophysicist and every one of the lectures bears the hallmark of all his work: precision, thoroughness, lucidity."-Sir Hermann Bondi, Nature The late S. Chandrasekhar was best known for his discovery of the upperlimit to the mass of a white dwarf star, for which he received the Nobel Prize in Physics in 1983. He was the author of many books, including The Mathematical Theory of Black Holes and, most recently, Newton’s Principia for the Common Reader.
