Sometimes our understanding of our universe is given a huge boost by one insightful thinker. Such a boost came in the first half of the 20th century, when an obscure Belgian priest put his mind to deciphering the nature of the cosmos. The Day Without Yesterday covers the modern history of an evolving universe, and how Georges Lemaître convinced a generation of thinkers to embrace the notion of cosmic expansion and the theory that this expansion could be traced backward to the cosmic origins, a starting point for space and time that Lemaître called "the day without yesterday".

Your nervous system is you. All the thoughts, perceptions, moods, passions, and dreams that make you an active, sentient being are the work of this amazing network of cells. For many centuries, people knew this was true. But no one was sure how it happened. Now, thanks to the exciting new field of neuroscience, we can chart the workings of the brain and the rest of the nervous system in remarkable detail to explain how neurons, synapses, neurotransmitters, and other biological processes produce all the experiences of everyday life, in every stage of life.

Emotions are inseparable from how we humans think, choose, and act. In Emotional Design, cognitive scientist Don Norman shows how the principles of human psychology apply to the invention and design of new technologies and products. In The Design of Everyday Things, Norman made the definitive case for human-centered design, showing that good design demanded that the user's must take precedence over a designer's aesthetic if anything, from light switches to airplanes, was going to work as the user needed.

In late April 1902, Mount Pelee, a volcano on the Caribbean island Martinique, began to wake up. It emitted clouds of ash and smoke for two weeks until violently erupting on May 8. Over 30,000 residents of St. Pierre were killed; they burned to death under rivers of hot lava and suffocated under pounds of hot ash. Only three people managed to survive: a prisoner trapped in a dungeon-like jail cell, a man on the outskirts of town, and a young girl found floating unconscious in a boat days later.   

It all began when we decided to get an airplane. I looked forward to riding with my husband over the countryside and enjoying the scenery. But one day he dropped the bomb. He told me I would need to learn to fly the plane, because, should something happen to him up there, I would have to put it on the ground. I began waking up at night silently screaming because I felt I was flying out of control up there with no way of getting the plane down. We ordered the Ground School materials, and thus the journey began.

Once home to the United States's largest plutonium production site, the Hanford Nuclear Reservation in Washington State is laced with 56 million gallons of radioactive waste. The threat of an explosive accident at Hanford is all too real—an event that could be more catastrophic than Chernobyl. The EPA designated Hanford the most toxic place in America; it is also the most expensive environmental clean-up job the world has ever seen, with a $677 billion price tag that keeps growing.

Before becoming an instructor in the Navy's Topgun program, Dave "Bio" Baranek was just another kid with a dream. Upon graduating from college, he joined the Navy with the goal of becoming a fighter pilot. But, his eyesight waning, he knew that he would never be able to reach that goal. Undaunted, he plowed ahead and found his niche as a radar intercept operator in the backseat of the sleek, new Grumman F-14 Tomcat.
