Physics.

At the heart of relativity theory, quantum mechanics, string theory, and much of modern cosmology lies one concept: symmetry. In Why Beauty Is Truth, world-famous mathematician Ian Stewart narrates the history of the emergence of this remarkable area of study. Stewart introduces us to such characters as the Renaissance Italian genius, rogue, scholar, and gambler Girolamo Cardano, who stole the modern method of solving cubic equations and published it in the first important book on algebra, and the young revolutionary Evariste Galois, who refashioned the whole of mathematics and founded the field of group theory only to die in a pointless duel over a woman before his work was published. Stewart also explores the strange numerology of real mathematics, in which particular numbers have unique and unpredictable properties related to symmetry. He shows how Wilhelm Killing discovered "Lie groups" with 14, 52, 78, 133, and 248 dimensions-groups whose very existence is a profound puzzle. Finally, Stewart describes the world beyond superstrings: the "octonionic" symmetries that may explain the very existence of the universe.

"A loving testament to the work and reward of the best friendships, the kind where your arms can’t distinguish burden from embrace.” — People New York Times Bestselling author Ann Patchett’s first work of nonfiction chronicling her decades-long friendship with the critically acclaimed and recently deceased author, Lucy Grealy. Ann Patchett and the late Lucy Grealy met in college in 1981, and, after enrolling in the Iowa Writer’s Workshop, began a friendship that would be as defining to both of their lives as their work. In Gealy's critically acclaimed and hugely successful memoir, Autobiography of a Face, she wrote about losing part of her jaw to childhood cancer, years of chemotherapy and radiation, and endless reconstructive surgeries. In Truth & Beauty, the story isn't Lucy's life or Ann's life, but the parts of their lives they shared together. This is a portrait of unwavering commitment that spans twenty years, from the long cold winters of the Midwest, to surgical wards, to book parties in New York. Through love, fame, drugs, and despair, this is what it means to be part of two lives that are intertwined...and what happens when one is left behind. This is a tender, brutal book about loving the person we cannot save. It is about loyalty and being uplifted by the sheer effervescence of someone who knew how to live life to the fullest.

From ancient times, philosophers, theologians, and artists have attempted to describe and categorize the defining virtues of civilization. In Truth, Beauty, and Goodness Reframed, renowned education authority Howard Gardner explores the meaning of the title's three virtues in an age when vast technological advancement and relativistic attitudes toward human nature have deeply shaken our moral worldview. His incisive examination reveals that although these concepts are changing faster than ever before, they are -- and will remain, with our stewardship -- cornerstones of our society. Designed to appeal to a wide readership, Truth, Beauty, and Goodness Reframed is an approachable primer on the foundations of ethics in the modern age.

Questions the promises and pitfalls of associating beauty with truth, showing how ideas of mathematical elegance have inspired, and have sometimes misled, scientists attempting to understand nature. The author also shows how the ancient Greeks constructed a concept of the world based on musical harmony.

"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 upper limit 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.
