Over the span of two hundred years, Great Britain established, governed, lost, and reconstructed an empire that embraced three continents and two oceanic worlds. The British ruled this empire by correlating incoming information about the conduct of subjects and aliens in imperial spaces with norms of good governance developed in London. Officials derived these norms by studying the histories of government contained in the official records of both the state and corporations and located in repositories known as archives.

Drawing together many histories - of anatomical evolution and city design, of treadmills and labyrinths, of walking clubs and sexual mores - Rebecca Solnit creates a fascinating portrait of the range of possibilities presented by walking. Arguing that the history of walking includes walking for pleasure as well as for political, aesthetic, and social meaning, Solnit focuses on the walkers whose everyday and extreme acts have shaped our culture, from philosophers to poets to mountaineers.

Derick Lugo had never been hiking. He certainly couldn't imagine going more than a day without manicuring his goatee. But with a job cut short and no immediate plans, this fixture of the New York comedy scene began to think about what he might do with months of free time. He had heard of the Appalachian Trail, but he had never seriously considered attempting to hike all 2,184.2 miles of it. Suddenly he found himself asking, Could he do it?

Enrico Fermi is unquestionably among the greats of the world's physicists, the most famous Italian scientist since Galileo. Called "the Pope" by his peers, he was regarded as infallible in his instincts and research. His discoveries changed our world; they led to weapons of mass destruction and conversely to life-saving medical interventions. This unassuming man struggled with issues relevant today, such as the threat of nuclear annihilation and the relationship of science to politics.

Churchill. Hitler. Stalin. Mussolini. Roosevelt. Five of the most impactful leaders of WW2, each with their own individualistic and idiosyncratic approach to warfare. But if we want to understand their military strategy, we must first understand the strategist. In The Strategists, Professor Phillips Payson O'Brien shows how the views these five leaders forged in WW1 are crucial to understanding how they fought WW2.

Gases are all around us—they fill our lungs, power our movement, create stars, and warm our atmosphere. Often invisible and sometimes odorless, these ubiquitous substances are also the least understood materials in our world, and always have been. It wasn’t long ago that gases were seen as the work of ancient spirits: the sudden closing of a door after a change in airflow signaled a ghost’s presence.

Today, for the first time in history, the scientific exploration of death and what happens when we die is real, active and ongoing. Contrary to popular perceptions, this subject is no longer the remit of philosophy, religion, or personal opinion. Truly remarkable scientific discoveries that will fundamentally affect everyone’s lives now and in the future are taking place, yet very few people are aware of them. Most people—including scientists and doctors—maintain strong beliefs about death and its experience. Those beliefs are rooted in traditional, and often cultural, notions of death.

For years, one group of Americans has worked as foot-soldiers for the most authoritarian regimes around the planet.

And now, some of them have begun turning their sights on American democracy itself. These Americans are known as foreign lobbyists, and many of them spent years ushering dictatorships directly into the halls of Washington, all while laundering the reputations of the most heinous regimes in the process.

We are living in a golden age in astronomy and in the search for life the universe. Over the last few decades, space exploration has shown that not only are there habitable environments within our solar system, but there are millions of exoplanets within our galaxy that could support life. We are on the cusp of breakthroughs that will revolutionize our understanding of our place in the cosmos in. In The Secret Life of the Universe, astrobiologist and the director of the Carl Sagan Center at the SETI Institute Nathalie A. Cabrol takes us to the frontiers of the search for life.
