"UltraMarathon Man: 50 Marathons - 50 States - 50 Days", a Journeyfilm documentary, follows Dean’s incredible step-by-step journey across the country.
Ultrarunning legend Dean Karnazes has run 262 miles-the equivalent of ten marathons-without rest. He has run over mountains, across Death Valley, and to the South Pole-and is probably the first person to eat an entire pizza while running. With an insight, candor, and humor rarely seen in sports memoirs (and written without the aid of a ghostwriter or cowriter), Ultramarathon Man has inspired tens of thousands of people-nonrunners and runners alike-to push themselves beyond their comfort zones and be reminded of "what it feels like to be truly alive," says Sam Fussell, author of Muscle.
Ultramarathon Man answers the questions Karnazes is continually asked:
- Why do you do it?
- How do you do it?
- Are you insane?
And in the new paperback edition, Karnazes answers the two questions he was most asked on his book tour:
- What, exactly, do you eat?
- How do you train to stay in such good shape?
In 1936, when he was just twenty-four years old, Alan Turing wrote a remarkable paper in which he outlined the theory of computation, laying out the ideas that underlie all modern computers. This groundbreaking and powerful theory now forms the basis of computer science. In Turing's Vision, Chris Bernhardt explains the theory, Turing's most important contribution, for the general reader. Bernhardt argues that the strength of Turing's theory is its simplicity, and that, explained in a straightforward manner, it is eminently understandable by the nonspecialist. As Marvin Minsky writes, “The sheer simplicity of the theory's foundation and extraordinary short path from this foundation to its logical and surprising conclusions give the theory a mathematical beauty that alone guarantees it a permanent place in computer theory.” Bernhardt begins with the foundation and systematically builds to the surprising conclusions. He also views Turing's theory in the context of mathematical history, other views of computation (including those of Alonzo Church), Turing's later work, and the birth of the modern computer.
In the paper, “On Computable Numbers, with an Application to the Entscheidungsproblem,” Turing thinks carefully about how humans perform computation, breaking it down into a sequence of steps, and then constructs theoretical machines capable of performing each step. Turing wanted to show that there were problems that were beyond any computer's ability to solve; in particular, he wanted to find a decision problem that he could prove was undecidable. To explain Turing's ideas, Bernhardt examines three well-known decision problems to explore the concept of undecidability; investigates theoretical computing machines, including Turing machines; explains universal machines; and proves that certain problems are undecidable, including Turing's problem concerning computable numbers.
Free solo climbing is a high-stakes sport: if you fall, you die. Expert free soloist Alex Honnold isn't afraid to push the limit; one of the most famous adventure athletes in the world, he has pioneered new routes, won awards, and shattered records. Alone on the Wall recounts the seven most astonishing achievements of Honnold's extraordinary life and career, brimming with lessons on living fearlessly, taking risks, and maintaining focus even in the face of extreme danger.
When the Black Stig disappeared off the end of an aircraft carrier in 2003, we were introduced to The White Stig. Faster. Stranger. Harder to keep clean. And ever since, millions have wondered – who is The Man in the White Suit? They're about to find out.
Ben Collins caught the car the bug young, kicking his dad's boss in the balls for not giving him a company Jag. This was the attitude that eventually led him to spend seven years sharing a cabin with Jeremy Clarkson's underwear, James May's PhD thesis and Richard Hammond's hairspray. Because he is The Stig.
Now he tells all about life inside the iconic white helmet. What it's like to guide a blind ex-RAF officer around the Top Gear track; pit a drug dealer's Mitsubishi Evo against a Trojan tank; set a Vauxhall Monara against Chloe the dancing Ninja; and race double-decker Routemasters against bendy buses. Not to mention all the inside stuff on how the show's amazing driving sequences are made.
He also reveals how he got to be there – setting
a Dunsfold lap time faster than Michael Schumacher's. Breaking records with the best of the best at Daytona and Le Mans.
It's an awesome story, told by an amazing man.
