Physicists have been exploring, debating, and questioning the general theory of relativity ever since Albert Einstein first presented itin 1915. Their work has uncovered a number of the universe's more surprising secrets, and many believe further wonders remain hidden within the theory's tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge.

In the summer of 2012, a team of six climbers set out to attempt the first ascent of one of the great unclimbed lines of the Himalaya - the giant Mazeno Ridge on Nanga Parbat, the world's ninth highest mountain. At 10 kilometers in length, the Mazeno is the longest route to the summit of an 8,000-meter peak. Ten expeditions had tried and failed to climb this enormous ridge.

An underwater exploration that overturns myths about fishes and reveals their complex lives, from tool use to social behavior. There are more than 30,000 species of fish - more than all mammals, birds, reptiles, and amphibians combined. But for all their breathtaking diversity and beauty, we rarely consider how fish think, feel, and behave.

From the author of the national best seller Chaos comes an outstanding biography of one of the most dazzling and flamboyant scientists of the 20th century that "not only paints a highly attractive portrait of Feynman but also . . . makes for a stimulating adventure in the annals of science." ( The New York Times).

In June 1944, the Nazis locked 18-year-old Dave Hersch into a railroad boxcar and shipped him from his hometown of Dej, Hungary, to Mauthausen Concentration Camp, the harshest, cruellest camp in the Reich. After 10 months in the granite mines of Mauthausen's nearby sub-camp, Gusen, he weighed less than 80 lbs., nothing but skin and bones. As Allied forces drew near Dave was forced to join a death march to Gunskirchen Concentration Camp, over 30 miles away. Soon after the start of the march, and more dead than alive, Dave summoned a burst of energy he did not know he had and escaped.

A definitive new edition of a classic memoir, published in association with the RAF Museum. Guy Gibson was the leader of the famous Dambusters raid and Enemy Coast Ahead is a vivid, honest account, widely regarded as one of the best books on World War II. It is also an insider's account that sets down in clear, honest detail the challenges that the RAF faced in the war against Germany's Luftwaffe. 

Happy Accidents is a fascinating, entertaining, and highly accessible look at the surprising role serendipity has played in some of the most important medical discoveries in the 20th century. What do penicillin, chemotherapy drugs, X-rays, Valium, the Pap smear, and Viagra have in common? They were each discovered accidentally, stumbled upon in the search for something else. In discussing medical breakthroughs, Dr. Morton Meyers makes a cogent, highly engaging argument for a more creative, rather than purely linear, approach to science. And it may just save our lives!

On February 1, 2003, Columbia disintegrated on reentry before the nation's eyes, and all seven astronauts aboard were lost. Author Mike Leinbach was a key leader in the search and recovery effort as NASA, FEMA, the FBI, the US Forest Service, and dozens more federal, state, and local agencies combed an area of rural east Texas the size of Rhode Island for every piece of the shuttle and her crew they could find. Assisted by hundreds of volunteers, it would become the largest ground search operation in US history.

Widely considered the greatest genius of all time, Albert Einstein revolutionized our understanding of the cosmos with his general theory of relativity and helped to lead us into the atomic age. Yet in the final decades of his life, he was also ignored by most working scientists, his ideas opposed by even his closest friends.

Bare-Faced Messiah tells the extraordinary story of L. Ron Hubbard, a penniless science fiction writer who founded the Church of Scientology, became a millionaire prophet, and convinced his adoring followers that he alone could save the world. Bare-Faced Messiah exposes the myths surrounding the fascinating and mysterious founder of the Church of Scientology - a man of hypnotic charm and limitless imagination - and provides the definitive account of how the notorious organization was created.

In 1939, tiny Finland waged war - the kind of war that spawns legends - against the mighty Soviet Union, and yet, their epic struggle has been largely ignored. Guerrillas on skis, heroic single-handed attacks on tanks, unfathomable endurance, and the charismatic leadership of one of this century's true military geniuses - these are the elements of both the Finnish victory and a gripping tale of war.

With the ongoing advancement of AI and other technologies, our world is becoming increasingly intelligent. From chatbots to innovations in brain-computer interfaces to the possibility of superintelligences leading to the Singularity later this century, our reality is being transformed before our eyes. This is commonly seen as the natural result of progress, but what if there's more to it than that? What if intelligence is an inevitability, an underlying property of the universe?

Most people will be shocked to learn that in 1933 a cabal of wealthy industrialists - in league with groups like the K.K.K. and the American Liberty League - planned to overthrow the U.S. government in a fascist coup. Their plan was to turn discontented veterans into American "brown shirts," depose F.D.R., and stop the New Deal. They clandestinely asked Medal of Honor recipient and Marine Major General Smedley Darlington Butler to become the first American Caesar. He, though, was a true patriot and revealed the plot to journalists and to Congress.

Jens Müller was one of only three men who successfully escaped from Stalag Luft III in March 1944 - the break that later became the basis for the famous film The Great Escape. In this vivid, informative memoir, Müller details what life in the camp was like, how the escapes were planned and executed, and the story of his personal breakout and success reaching the RAF Leuchars base in Scotland. 

Sparked by a provocative comment to BigThink.com last fall, and fueled by a highly controversial debate with Creation Museum curator Ken Ham, Bill Nye's campaign to confront the scientific shortcoming of creationism has exploded in just a few months into a national crusade.
