A unique compilation of logical teasers and lateral-thinking problems designed to stretch your brainpower and strengthen your mind. Riddles, paradoxes, and conundrums have been confusing and confounding people since at least the time of the Ancient Greeks. The eponymous riddle, according to legend, was devised by Albert Einstein as a child. He claimed that only about 2% of the population would be able to work out the correct answer. There are no tricks and there is only one answer. It requires the cool application of logic to solve. And a lot of patience. Einstein's Riddle features fifty of the toughest logic problems, lateral thinking puzzles, and tests of mental agility. By turns entertaining and infuriating, the puzzles challenge our preconceptions, tell us about how we reason, and provide a rigorous intellectual workout.

The universe throws a lot of puzzles at us, as Einstein well knew. Solving them requires logic, creativity, diligence, and a good memory. In this puzzle book, you can challenge your inner Einstein with logic, verbal, and number games, as well as some devious riddles. Every page offers something new. Puzzle types include cross math, logidoku, number sequence, letterbox, and plenty of number and word riddles. Over 190 puzzles. Answers in back of book. Spiral bound for easy puzzle working.

NATIONAL BESTSELLER • A modern classic explores the connections between science and art, the process of creativity, and ultimately the fragility of human existence. “A magical, metaphysical realm ... Captivating, enchanting, delightful.” —The New York Times Einstein’s Dreams is a fictional collage of stories dreamed by Albert Einstein in 1905, about time, relativity and physics. As the defiant but sensitive young genius is creating his theory of relativity, a new conception of time, he imagines many possible worlds. In one, time is circular, so that people are fated to repeat triumphs and failures over and over. In another, there is a place where time stands still, visited by lovers and parents clinging to their children. In another, time is a nightingale, sometimes trapped by a bell jar. Now translated into thirty languages, Einstein’s Dreams has inspired playwrights, dancers, musicians, and painters all over the world. In poetic vignettes, it explores the connections between science and art, the process of creativity, and ultimately the fragility of human existence.

For Albert Einstein, 1905 was a remarkable year. It was also a miraculous year for the history and future of science. In six short months, from March through September of that year, Einstein published five papers that would transform our understanding of nature. This unparalleled period is the subject of John Rigden's book, which deftly explains what distinguishes 1905 from all other years in the annals of science, and elevates Einstein above all other scientists of the twentieth century. Rigden chronicles the momentous theories that Einstein put forth beginning in March 1905: his particle theory of light, rejected for decades but now a staple of physics; his overlooked dissertation on molecular dimensions; his theory of Brownian motion; his theory of special relativity; and the work in which his famous equation, E = mc2, first appeared. Through his lucid exposition of these ideas, the context in which they were presented, and the impact they had--and still have--on society, Rigden makes the circumstances of Einstein's greatness thoroughly and captivatingly clear. To help readers understand how these ideas continued to develop, he briefly describes Einstein's post-1905 contributions, including the general theory of relativity. One hundred years after Einstein's prodigious accomplishment, this book invites us to learn about ideas that have influenced our lives in almost inconceivable ways, and to appreciate their author's status as the standard of greatness in twentieth-century science.
