By 1930, no place in the world was less well explored than Greenland. The native Inuit had occupied the relatively accessible west coast for centuries. The east coast, however, was another story. In August 1930, Henry George Watkins (nicknamed “Gino”), a twenty-three-year-old British explorer, led thirteen scientists and explorers on an ambitious expedition to the east coast of Greenland and into its vast and forbidding interior to set up a permanent meteorological base on the icecap, 8,200 feet above sea level.

In these Messenger Lectures, originally delivered at Cornell University and recorded for television by the BBC, Richard Feynman offers an overview of selected physical laws and gathers their common features into one broad principle of invariance. He maintains at the outset that the importance of a physical law is not "how clever we are to have foundit out but…how clever nature is to pay attention to it" and steers his discussions toward a final exposition of the elegance and simplicity of all scientific laws.

>When South African conservationist Lawrence Anthony was asked to accept a herd of "rogue" wild elephants on his Thula Thula game reserve in Zululand, his common sense told him to refuse. But he was the herd's last chance of survival: they would be killed if he wouldn't take them. In order to save their lives, Anthony took them in. In the years that followed he became a part of their family. And as he battled to create a bond with the elephants, he came to realize that they had a great deal to teach him about life, loyalty, and freedom.

In Rewire Your Anxious Brain, psychologist Catherine Pittman and author Elizabeth Karle show how the amygdala and cortex (both key parts of the brain) are essential players in the neuropsychology of anxiety. The amygdala acts as a primal response, and oftentimes, when this part of the brain processes fear, you may not even understand why you are afraid. By comparison, the cortex is the center of “worry.” That is, obsessing, ruminating, and dwelling on things that may or may not happen.

One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

In this grand poetic vision of the universe, Lawrence Krauss tells the dramatic story of the discovery of the hidden world that underlies reality - and our place within it. Reality is not what you think or sense - it’s weird, wild, and counterintuitive, and its inner workings seem at least as implausible as the idea that something can come from nothing. With his trademark wit and accessible style, Krauss leads us to realms so small that they are invisible to microscopes, to the birth and rebirth of light, and into the natural forces that govern our existence.

Faced with the ceaseless stream of news about war, crime, and terrorism, one could easily think we live in the most violent age ever seen.
