In this poetic audiobook, hear the words of legendary outdoorsman John Muir's entreaty to the American people imploring them to develop, as he did, a connection to their national parks. An ardent outdoorsman, a gifted writer, a dedicated preservationist, and a spiritual beacon, John Muir worked in his life and in his writing to inspire everyone to find a love for the wilderness and to become invested in its preservation.

Inspired by Albert Einstein's theory of relativity and Bertrand Russell and David Hilbert's pursuit of the fundamental rules of mathematics, some of the most brilliant minds of the generation came together in post-World War I Vienna to present the latest theories in mathematics, science, and philosophy and to build a strong foundation for scientific investigation. Composed of such luminaries as Kurt Gödel and Rudolf Carnap, and stimulated by the works of Ludwig Wittgenstein and Karl Popper, the Vienna Circle left an indelible mark on science.

With compassionate stories of his patients and their conditions, Dr. Leschziner illustrates the neuroscience behind our sleeping minds, revealing the many biological and psychological factors necessary in getting the rest that will not only maintain our physical and mental health, but improve our cognitive abilities and overall happiness.

In 1987, Robert Harris happened upon an unusual job posting in the local paper—a new warden service was being set up on the island of Skellig Michael, and the deadline was imminent. Just weeks later he was on his way to set up camp in one of Ireland’s most remote locations, unaware that he would be making that same journey every May for the next 30 years.

With temperatures rising and the risk of disasters growing, our world is increasingly vulnerable. Most people see disasters as freak, natural events that are unpredictable and unpreventable. But that simply isn’t the case - disasters are avoidable, but when they do strike, there are strategic ways to manage the fallout.

After a few billion years of bearing witness to life on Earth, of watching one hundred billion humans go about their day-to-day lives, of feeling unbelievably lonely, and of hearing its own story told by others, The Milky Way would like a chance to speak for itself. All one hundred billion stars and fifty undecillion tons of gas of it. It all began some thirteen billion years ago, when clouds of gas scattered through the universe's primordial plasma just could not keep their metaphorical hands off each other.

Today, we take for granted that a telescope allows us to see galaxies millions of light years away. But before its invention, people used nothing more than their naked eye to fathom what took place in the visible sky. So how did four men in the 1500s - of different nationality, age, religion, and class - collaborate to discover that the Earth revolved around the Sun? With this radical discovery that went against the Church, they created our contemporary world. Heaven on Earth is an intimate examination of this scientific family.

James Smithson is best known as the founder of the Smithsonian Institution, but few people know his full and fascinating story. He was a widely respected chemist and mineralogist and a member of the Royal Society, but in 1865, his letters, collection of 10,000 minerals, and more than 200 unpublished papers were lost to a fire in the Smithsonian Castle. His scientific legacy was further written off as insignificant in an 1879 essay published through the Smithsonian 50 years after his death - a claim that author Steven Turner demonstrates is far from the truth.

On July 20, 1969, Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon, a moment forever ingrained in history. Perhaps the world's greatest technological achievement - and a triumph of American spirit and ingenuity - the Apollo 11 mission, and the entire Apollo program, was a mammoth undertaking involving more than 410,000 men and women dedicated to putting a man on the Moon and winning the Space Race against the Soviets.

North America's biggest cat was once killed for bounty dollars, slaughtered with impunity and driven toward extinction. But today's cat of intrigue, despite our lingering fears and misconceptions, has returned to much of its native range in the western United States and gained respect as a predator integral and necessary to wild ecosystems. This turnaround was triggered by one man: Maurice Hornocker. Cougars on the Cliff recounts the early years of his research when he tracked lions following a dog's nose and footprints in the snow—before telemetry was available.

Salk became a cultural hero and icon for a whole generation. Now, at the fiftieth anniversary of the first national vaccination program, and as humanity is tantalizingly close to eradicating polio worldwide, comes this unforgettable chronicle. Salk's work was an unparalleled achievement, and it makes for a magnificent listen.

Now settled into the sleepy Yorkshire village of Darrowby, and married to Helen the farmer’s daughter, James Herriot thinks he’s finally got himself sorted. But life as a vet in the 1930s was never going to be easy. Quite aside from his unpredictable colleagues, brothers Siegfried and Tristan Farnon, he must contend with new fangled medical techniques, delivering calves after far too much home-made wine, and a grudge holding dog called Magnus who never forgets. And then, with Britain on the verge of war, James faces a decision that could separate him from Darrowby – and Helen – for ever....

In this partially autobiographical work, best-selling author Lewis Thomas offers insights on subjects as wide-ranging as gender differences, how it feels to be a patient, human vs. computer intelligence, the future of cancer research, and the longevity of the planet—interspersing all with charming anecdotes about his family, his colleagues and himself.

Acclaimed scientist and author Bernd Heinrich has returned every year since boyhood to a beloved patch of western Maine woods. What is the biology in humans of this deep-in-the-bones pull toward a particular place, and how is it related to animal homing? Heinrich explores the fascinating science chipping away at the mysteries of animal migration: how geese imprint true visual landscape memory; how scent trails are used by many creatures, from fish to insects to amphibians, to pinpoint their home if they are displaced from it; and more.

The tens of millions who perished in World War I understandably marred the conception of the first decades of the 20th century. However, during that time, unparalleled minds from all over the globe unsnarled age-old mysteries and perfected prevailing theories, conjuring up wave after wave of breakthroughs that catapulted the world of science to unprecedented heights. Owing to this influx of novel ideas and innovative concepts, conferences had to be assembled to keep the relevant scientific spheres apprised of the latest advances.

In 1953, a 27-year-old factory worker named Henry Molaison - who suffered from severe epilepsy - received a radical new version of the then-common lobotomy, targeting the most mysterious structures in the brain. The operation failed to eliminate Henry’s seizures, but it did have an unintended effect: Henry was left profoundly amnesic, unable to create long-term memories. Over the next 60 years, Patient H.M., as Henry was known, became the most studied individual in the history of neuroscience, a human guinea pig who would teach us much of what we know about memory today.

Upstream is an in-depth and timely look at salmon - one of the last wild foods on our table - for fans of Susan Orlean, Mark Kurlansky, and John McPhee. As the author travels to meet a variety of colorful people associated with this unique species, from Alaskan anglers to fish farm owners to four-star chefs, he reports on its remarkable place at the intersection of nature, commerce, cuisine, and human history.

The Voyage of the Beagle - or, to give it its full title, Journal of researches into the Natural History and Geology of the Countries visited during the Voyage round the World of H.M.S. Beagle under command of Captain FitzRoy, R.N. - is much more than merely an account of Darwin's scientific observations in his 1831 - 36 travels across the globe: it is fine travel writing in its own right.
