. . full of intellectual treats and tricks, of whimsy and deep scientific philosophy. It is highbrow entertainment at its best, a teasing challenge to all who aspire to think about the universe." — New York Herald TribuneOne of the world's foremost nuclear physicists (celebrated for his theory of radioactive decay, among other accomplishments), George Gamow possessed the unique ability of making the world of science accessible to the general reader.He brings that ability to bear in this delightful expedition through the problems, pleasures, and puzzles of modern science. Among the topics scrutinized with the author's celebrated good humor and pedagogical prowess are the macrocosm and the microcosm, theory of numbers, relativity of space and time, entropy, genes, atomic structure, nuclear fission, and the origin of the solar system.In the pages of this book readers grapple with such crucial matters as whether it is possible to bend space, why a rocket shrinks, the "end of the world problem," excursions into the fourth dimension, and a host of other tantalizing topics for the scientifically curious. Brimming with amusing anecdotes and provocative problems, One Two Three . . . Infinity also includes over 120 delightful pen-and-ink illustrations by the author, adding another dimension of good-natured charm to these wide-ranging explorations.Whatever your level of scientific expertise, chances are you'll derive a great deal of pleasure, stimulation, and information from this unusual and imaginative book. It belongs in the library of anyone curious about the wonders of the scientific universe. "In One Two Three . . . Infinity, as in his other books, George Gamow succeeds where others fail because of his remarkable ability to combine technical accuracy, choice of material, dignity of expression, and readability." — Saturday Review of Literature

    The material is arranged chronologically beginning with archaic origins and covers Egyptian, Mesopotamian, Greek, Chinese, Indian, Arabic and European contributions done to the nineteenth century and present day.

    A simple web search picks out a handful of relevant needles from the world's biggest haystack: the billions of pages on the World Wide Web. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers; and we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? This is the first book to answer that question in language anyone can understand, revealing the extraordinary ideas that power our PCs, laptops, and smartphones. Using vivid examples, John MacCormick explains the fundamental "tricks" behind nine types of computer algorithms, including artificial intelligence (where we learn about the "nearest neighbor trick" and "twenty questions trick"), Google's famous PageRank algorithm (which uses the "random surfer trick"), data compression, error correction, and much more. These revolutionary algorithms have changed our world: this book unlocks their secrets, and lays bare the incredible ideas that our computers use every day.

    Jill is one of those “accidental athletes” who stumbled into endurance racing shortly after she moved to Alaska in 2005. After a hundred miles, her first race only scratched the surface of the historic trail that spans a vast and frozen wilderness. Ever since, she dreamed about the chiming of ice crystals at thirty below zero, black spruce shadows in the moonlight, the ethereal dance of the Northern Lights, and a journey that could take her deeper into this transcendental world — the thousand-mile race to Nome. After ten years of dreaming, she finally made the leap in 2016. Fitness, however, remained elusive as ambitious preparations left a wake of failures, sickness and injury. Even the existence of the trail remained in question — throughout the winter, Alaska experienced unprecedented heat waves and snow melt that threatened to render the Iditarod Trail impassable. By the time Jill lined up at the start, she was ready to chuck her dream into the barely-frozen lake. Instead, she pedaled across waterlogged ice, repeating her mantra of “one day at a time.” This account is not just a story about seeking beauty, overcoming setbacks and uncovering hidden strength — it’s a journey into the benevolent heart of the coldest, loneliest trail.

    Reveals mathematics' great power as an alternative language for understanding things and explores such concepts as logic as a computing tool, digital versus analog processes and communication as information transmission.

    Bell, a leading figure in mathematics in America for half a century. Men of Mathematics accessibly explains the major mathematics, from the geometry of the Greeks through Newton's calculus and on to the laws of probability, symbolic logic, and the fourth dimension. In addition, the book goes beyond pure mathematics to present a series of engrossing biographies of the great mathematicians -- an extraordinary number of whom lived bizarre or unusual lives. Finally, Men of Mathematics is also a history of ideas, tracing the majestic development of mathematical thought from ancient times to the twentieth century. This enduring work's clear, often humorous way of dealing with complex ideas makes it an ideal book for the non-mathematician.

    Hermann Weyl explores the concept of symmetry beginning with the idea that it represents a harmony of proportions, and gradually departs to examine its more abstract varieties and manifestations--as bilateral, translatory, rotational, ornamental, and crystallographic. Weyl investigates the general abstract mathematical idea underlying all these special forms, using a wealth of illustrations as support. Symmetry is a work of seminal relevance that explores the great variety of applications and importance of symmetry.

    Eric Goodman’s visionary approach to mindful movement corrects the complacent adaptations that lead to back and joint pain, and teaches us to harness the body’s natural movement patterns into daily activities to make us fit, healthy, and pain free.Our sedentary lifestyle has led to an epidemic of chronic pain. By adapting to posture and movement that have us out of balance—including sitting all day at a keyboard, tilting our heads forward to look at our phones—we consistently compromise our joints, give our organs less room to function, and weaken our muscles. How we hold and live in our bodies is fundamental to our overall health, and the good news is that we all hold the key to a healthier body.Dr. Goodman has spent years studying human physiology and movement. He has trained world-class athletes for better performance, and has healed people of all ages and occupations of lifelong debilitating pain. His theory of self-healing is now available to everyone. His practical program trains the posterior muscle chain—shoulders, back, butt, and legs—shifting the burden of support away from joints and putting it back where it belongs: into large muscle groups.Filled with helpful diagrams and sixty color photographs, True to Form shows readers how to successfully integrate these powerful movements into everyday life—from playing with the kids to washing dishes to long hours in the office—transforming ordinary physical actions into active and mindful movements that help to eliminate pain, up your game, or simply feel more energetic. True to Form shows you how to move better, breathe better, and get back to using your body the way nature intended.

    Len Fisher turns his attention to the science of cooperation in his lively and thought-provoking book. Fisher shows how the modern science of game theory has helped biologists to understand the evolution of cooperation in nature, and investigates how we might apply those lessons to our own society. In a series of experiments that take him from the polite confines of an English dinner party to crowded supermarkets, congested Indian roads, and the wilds of outback Australia, not to mention baseball strategies and the intricacies of quantum mechanics, Fisher sheds light on the problem of global cooperation. The outcomes are sometimes hilarious, sometimes alarming, but always revealing. A witty romp through a serious science, Rock, Paper, Scissors will both teach and delight anyone interested in what it what it takes to get people to work together.
