It was Richard Feynman's outrageous and scintillating method of teaching that earned him legendary status among students and professors of physics. From 1961 to 1963, Feynman delivered a series of lectures at the California Institute of Technology that revolutionized the teaching of physics. In Six Not-So-Easy Pieces, taken from these famous Lectures on Physics, Feynman delves into one of the most revolutionary discoveries in twentieth-century physics: Einstein's theory of relativity.

Daughter. Duhitár-. Dustr. Dukte. Listen to these English, Sanskrit, Armenian and Lithuanian words, all meaning the same thing, and you hear echoes of one of history’s most unlikely journeys. All four languages—along with hundreds of others, from French and Gaelic, to Persian and Polish—trace their origins to an ancient tongue spoken as the last ice age receded. This language, which we call Proto-Indo-European, was born between Europe and Asia and exploded out of its cradle, fragmenting as it spread east and west.

With his characteristic eyebrow-raising behavior, Richard P. Feynman once provoked the wife of a Princeton dean to remark, "Surely you're joking, Mr. Feynman!" But the many scientific and personal achievements of this Nobel Prize-winning physicist are no laughing matter. Here, woven with his scintillating views on modern science, Feynman relates the defining moments of his accomplished life.

A Russian dissident, a Jesuit priest, and an American mule skinner are but a few of the bold visionaries who crafted the scientific story of cosmic origins. The collective insights of these and numerous creative thinkers advanced human understanding from mythology to mathematics, yielding falsifiable alternatives to ancient folklore and campfire tales. Listening to the Big Bang tells the dramatic human story—filled with colorful characters, unsung catalysts, and glorified heroes—which made the Big Bang the leading cosmological theory.

As he explained in his #1 New York Times best­seller Principles, Ray Dalio believes that most everything happens over and over again through time so that by studying patterns one can understand the cause-effect relationships behind events and develop principles for dealing with them well. In this three-part research series, he does just that for big debt crises and shares his template in the hopes of reducing the chances of big debt crises hap­pening and helping them be better managed in the future.

For decades, politicians, policymakers, and investors have debated these questions, but the Big Debt Cycle that helps answer them is not talked about or well understood. With the US debt issue coming to a head, Dalio’s How Countries Go Broke provides the first-ever detailed analysis of the Big Debt Cycle, explaining its implications and offering a surprisingly straightforward solution to getting debt problems like the ones the US faces under control.

From an acclaimed Harvard professor and one of Time’s most influential people, this paradigm-shifting audiobook shows how almost everything we think we know about aging is wrong, offers a front-row seat to the amazing global effort to slow, stop, and reverse aging, and calls listeners to consider a future where aging can be treated.

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

Bill Bryson has been an enormously popular author both for his travel books and for his books on the English language. Now, this beloved comic genius turns his attention to science. Although he doesn't know anything about the subject (at first), he is eager to learn, and takes information that he gets from the world's leading experts and explains it to us in a way that makes it exciting and relevant.

From the celebrated neurobiologist and primatologist, a landmark, genre-defining examination of human behavior, both good and bad, and an answer to the question: Why do we do the things we do? Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: He starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.
