do it? How should you flip your mattress to get the maximum wear out of it? How does Google search the Internet? How many people should you date before settling down? Believe it or not, math plays a crucial role in answering all of these questions and more.Math underpins everything in the cosmos, including us, yet too few of us understand this universal language well enough to revel in its wisdom, its beauty — and its joy. This deeply enlightening, vastly entertaining volume translates math in a way that is at once intelligible and thrilling. Each trenchant chapter of The Joy of x offers an “aha!” moment, starting with why numbers are so helpful, and progressing through the wondrous truths implicit in π, the Pythagorean theorem, irrational numbers, fat tails, even the rigors and surprising charms of calculus. Showing why he has won awards as a professor at Cornell and garnered extensive praise for his articles about math for the New York Times, Strogatz presumes of his readers only curiosity and common sense. And he rewards them with clear, ingenious, and often funny explanations of the most vital and exciting principles of his discipline.Whether you aced integral calculus or aren’t sure what an integer is, you’ll find profound wisdom and persistent delight in The Joy of x.

    The author writes of an encounter they had with a being called 'Tal' who looked human but claimed to be an alien. The author believes that this person was in fact an alien due to the content of their conversation and the events that lead to and followed it. The author requested we divulge no information about the book that could influence the first reading of it. We will reveal, however, that in the conversation, Tal attempts to show the author how a far more advanced life form would observe and function in the universe. Tal does not describe a technological superiority, but an actual perceptual and physical difference that leads to a fundamentally greater understanding of the world. The conversation covers many topics; including time, the perception of extra dimensions, quantum theory, infinity, and consciousness. Tal uses examples from modern scientific theory, ancient religions, alien worlds and even chess. The author wished to publish this book because they felt that this encounter dramatically changed their life.

    Unique in basing relativity on the Principle of Equivalence of Gravitation and Inertia over Riemannian geometry, this book explores relativity experiments and observational cosmology to provide a sound foundation upon which analyses can be made. Covering special and general relativity, tensor analysis, gravitation, curvature, and more, this book provides an engaging, insightful introduction to the forces that shape the universe.
