Over 1500 years before Leonardo Da Vinci became the Renaissance Man, antiquity had its own in the form of Archimedes, one of the most famous Ancient Greeks. An engineer, mathematician, physicist, scientist and astronomer all rolled into one, Archimedes has been credited for making groundbreaking discoveries, some of which are undoubtedly fact and others that are almost certainly myth.

The Spartans of ancient Greece were a powerful and unique people, radically different from any civilization before or since. A society of warrior-heroes, they were living exemplars of self-sacrifice, community endeavor, and achievement against all odds, qualities that today signify the ultimate in heroism. Scholars even believe that Thomas More had Sparta specifically in mind when he coined the term "Utopia".

Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

The secretive Mysteries conducted at Eleusis in Greece for nearly two millennia have long puzzled scholars with strange accounts of initiates experiencing otherworldly journeys. In this groundbreaking work, three experts - a mycologist, a chemist, and a historian - argue persuasively that the sacred potion given to participants in the course of the ritual contained a psychoactive entheogen. The authors then expand the discussion to show that natural psychedelic agents have been used in spiritual rituals across history and cultures.

The first volume of Will Durant's Pulitzer Prize-winning series, Our Oriental Heritage: The Story of Civilization, Volume I chronicles the early history of Egypt, the Middle East, and Asia.

In the year 493, the leader of a vast confederation of Gothic warriors, their wives, and children personally cut down Odoacer, the man famous for deposing the last Roman emperor in 476. That leader became Theoderic the Great (454-526). This engaging history of his life and reign immerses listeners in the world of the warrior-king who ushered in decades of peace and stability in Italy as king of Goths and Romans.

There may never be another era of science like the first half of the twentieth century, when many of the most important physicists ever to live—Marie Curie, Max Planck, Wolfgang Pauli, Niels Bohr, Werner Heisenberg, Ernst Schrödinger, Albert Einstein, and others—came together to uncover the quantum world: a concept so outrageous and shocking, so contrary to traditional physics, that its own founders rebelled against it until the equations held up and fundamentally changed our understanding of reality. Tobias Hürter takes us back to this uniquely momentous and harrowing time.

Many people take math in high school and promptly forget much of it. But math plays a part in all of our lives all of the time, whether we know it or not. In The Joy of x, Steven Strogatz expands on his hit New York Times series to explain the big ideas of math gently and clearly, with wit, and insight.

Until the publication of this captivating biography, no such volume on Trajan's life has been tailored to the general listener. The unique book illuminates a neglected period of ancient Roman history. Trajan rose from fairly obscure beginnings to become the emperor of Rome. He was born in Italica, an Italic settlement close to modern Seville in present-day Spain, and is the first Roman Emperor to be born outside of Rome. His remarkable rise from officer to general and then to emperor in just over twenty years reveals a shrewd politician who maintained absolute power.

Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole’s core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. In White Holes, he reveals the mind of a scientist at work.

My Big TOE: Awakening, written by a nuclear physicist in the language of contemporary culture, unifies science and philosophy, physics and metaphysics, mind and matter, purpose and meaning, the normal and the paranormal. The entirety of human experience (mind, body, and spirit) including both our objective and subjective worlds is brought together under one seamless scientific understanding.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat? Drawing on decades of research, Harvard psychiatrist Dr. Chris Palmer outlines a revolutionary new understanding that for the first time unites our existing knowledge about mental illness within a single framework: mental disorders are metabolic disorders of the brain. Brain Energy will transform the field of mental health, and the lives of countless people around the world.

Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe. Now, Tyson invites us to go behind the scenes of his public fame by unveiling his candid correspondence with people across the globe who have sought him out in search of answers. In this hand-picked collection of 100 letters, Tyson draws upon cosmic perspectives to address a vast array of questions about science, faith, philosophy, life, and of course, Pluto.

Hilarious, fascinating, and a roller coaster of dizzying, historical what-ifs, Napoleon's Hemorrhoids is a potpourri for serious historians and casual history buffs. In one of Phil Mason's many revelations, you'll learn that Communist jets were two minutes away from opening fire on American planes during the Cuban missile crisis, when they had to turn back as they were running out of fuel. You'll discover that before the Battle of Waterloo, Napoleon's painful hemorrhoids prevented him from mounting his horse to survey the battlefield.

Dr. Catherine Kleier invites us to open our eyes to the phenomenal world of plant life and to the process she calls “Natura Revelata”, the joy of celebrating and learning from the secrets of nature. As Dr. Kleier shares her knowledge with contagious excitement for her subject, she emphasizes the middle ground: Instead of focusing on cell microbiology or the study of ecosystems and habitats, she stresses the basic biology, function, and the amazing adaptations of the plants we see all around us.

In this illuminating audiobook, Tyson and coauthor James Trefil, a renowned physicist and science popularizer, take on the big questions that humanity has been posing for millennia - How did life begin? What is our place in the universe? Are we alone? - and provide answers based on the most current data, observations, and theories.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity.
