One of the most valuable skills in our economy is becoming increasingly rare. If you master this skill, you'll achieve extraordinary results.

Deep work is the ability to focus without distraction on a cognitively demanding task. It's a skill that allows you to quickly master complicated information and produce better results in less time. Deep work will make you better at what you do and provide the sense of true fulfillment that comes from craftsmanship. In short, deep work is like a super power in our increasingly competitive twenty-first century economy. And yet, most people have lost the ability to go deep-spending their days instead in a frantic blur of e-mail and social media, not even realizing there's a better way.

In Deep Work, author and professor Cal Newport flips the narrative on impact in a connected age. Instead of arguing distraction is bad, he instead celebrates the power of its opposite. Dividing this book into two parts, he first makes the case that in almost any profession, cultivating a deep work ethic will produce massive benefits. He then presents a rigorous training regimen, presented as a series of four "rules," for transforming your mind and habits to support this skill.

A mix of cultural criticism and actionable advice, Deep Work takes the reader on a journey through memorable stories-from Carl Jung building a stone tower in the woods to focus his mind, to a social media pioneer buying a round-trip business class ticket to Tokyo to write a book free from distraction in the air-and no-nonsense advice, such as the claim that most serious professionals should quit social media and that you should practice being bored. Deep Work is an indispensable guide to anyone seeking focused success in a distracted world.

The official guide to the science behind the Battlestar Galactica universe Battlestar Galactica ( BSG ) has been called the best show on television, and as real as science fiction gets. It has dealt with issues of religious freedom, patriotism, terrorism, genetic engineering, and the ultimate science fiction question: what does it mean to be human? While the re-imagined BSG may not be packed with cool techie tools (the bad guys don't even have laser guns for frak's sake!), this book shows that the science in the series has a lot to say about the use of science and technology in our lives today. What are the principles behind artificial gravity and sublight propulsion? Are Cylons men or machines? How are humanoid Cylons able to interface with computers? By tackling these and other intriguing questions, The Science of Battlestar Galactica takes us billions of miles away from Earth so that we can turn around and see ourselves from a different perspective.

A psychological thriller about a group of scientists who investigate a spaceship discovered on the ocean floor. In the middle of the South Pacific, a thousand feet below the surface, a huge vessel is unearthed. Rushed to the scene is a team of American scientists who descend together into the depths to investigate the astonishing discovery. What they find defies their imaginations and mocks their attempts at logical explanation. It is a spaceship, but apparently it is undamaged by its fall from the sky. And, most startling, it appears to be at least three hundred years old, containing a terrifying and destructive force that must be controlled at all costs.

Written as Jeffery Hudson in 1968.
