Ulysses S. Grant's life has typically been misunderstood. All too often he is caricatured as a chronic loser and an inept businessman or as the triumphant but brutal Union general of the Civil War. But these stereotypes don't come close to capturing him, as Chernow reveals in his masterful biography, the first to provide a complete understanding of the general and president whose fortunes rose and fell with dizzying speed and frequency.

In 1988, 43-year-old Jeff Winston died of a heart attack. But then he awoke, and it was 1963; Jeff was 18 all over again, his memory of the next two decades intact. This time around, Jeff would gain all the power and wealth he never had before. This time around he'd know how to do it right. Until next time.

In The End Is Always Near, Dan Carlin looks at questions and historical events that force us to consider what sounds like fantasy; that we might suffer the same fate that all previous eras did. Will our world ever become a ruin for future archaeologists to dig up and explore? The questions themselves are both philosophical and like something out of The Twilight Zone.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

Clare and Henry have known each other since Clare was six and Henry was 36. They were married when Clare was 23 and Henry was 31. Impossible but true, because Henry is one of the first people diagnosed with Chrono-Displacement Disorder: periodically his genetic clock resets and he finds himself misplaced in time, pulled to moments of emotional gravity from his life, past and future. His disappearances are spontaneous, his experiences unpredictable, alternately harrowing and amusing.

Philosophers have long puzzled over the nature of space, time, and matter. These inquiries led to the flowering of physics with the Scientific Revolution in the 17th century. Since then, the spectacular success of modern physics might appear to have made philosophy irrelevant. But new theories have created a new range of philosophical concerns: What is the shape of space? Is time travel possible? Is there a grand unified theory that unites all of physics?

Dennis E. Taylor, author of the best-selling Bobiverse trilogy, explores a whole different, darker world in this sci-fi stand-alone. Determined to give his wife and children a better life back home, Ivan Pritchard ventures to the edge of known space to join the crew of the Mad Astra as an asteroid miner. He's prepared for hard work and loneliness—but not the unthinkable. After coming into contact with a mysterious alien substance, Pritchard finds an unwelcome entity sharing his mind, and a disturbing physical transformation taking place.

Imagine a world without bees, butterflies, and flowering plants. That was Earth 125 million years ago. Turn back the clock 400 million years, and there were no trees. At 450 million years in the past, even the earliest insects had not yet developed. And looking back 500 million years, the land was devoid of life, which at that time flourished in a profusion of strange forms in the oceans. These and other major turning points are the amazing story of evolution.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity. He was trying to find an equation that explained all physical reality - a theory of everything. Experimental physicist and award-winning educator Dr. Don Lincoln takes you on this exciting journey in The Theory of Everything: The Quest to Explain All Reality. Suitable for the intellectually curious at all levels and assuming no background beyond basic high-school math, these 24 half-hour lectures cover recent developments at the forefront of particle physics and cosmology.

The Science of Information: From Language to Black Holes covers the exciting concepts, history, and applications of information theory in 24 challenging and eye-opening half-hour lectures taught by Professor Benjamin Schumacher of Kenyon College. A prominent physicist and award-winning educator at one of the nation’s top liberal arts colleges, Professor Schumacher is also a pioneer in the field of quantum information, which is the latest exciting development in this dynamic scientific field.
