On June 6, 1761, the world paused to observe a momentous occasion: the first transit of Venus between the earth and the sun in more than a century. Through that observation, astronomers could calculate the size of the solar system - but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.

Since the 1930s, the scale of scientific endeavors has grown exponentially. The birth of Big Science can be traced to Berkeley, California, nearly nine decades ago, when a resourceful young scientist pondered his new invention and declared, "I'm going to be famous!" Ernest Orlando Lawrence's cyclotron would revolutionize nuclear physics, but that was only the beginning of its impact.This is the incredible story of how one invention changed the world and of the man principally responsible for it all. Michael Hiltzik tells the riveting full story here for the first time.

A cataclysmic planetary phenomenon is gathering force deep within the Earth. The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization.

La espléndida biografía de Alexander von Humboldt, el héroe perdido de la ciencia y padre de la ecología.

We all make mistakes. Nobody’s perfect. Not even some of the greatest geniuses in history, as Mario Livio tells us in this marvelous story of scientific error and breakthrough. Charles Darwin, William Thomson (Lord Kelvin), Linus Pauling, Fred Hoyle, and Albert Einstein were all brilliant scientists. Each made groundbreaking contributions to his field - but each also stumbled badly. These five scientists expanded our knowledge of life on Earth, the evolution of the Earth itself, and the evolution of the universe, despite and because of their errors. As Mario Livio luminously explains, the scientific process advances through error.

In 1942, a team at the University of Chicago achieved what no one had before: a nuclear chain reaction. At the forefront of this breakthrough stood Enrico Fermi. Straddling the ages of classical physics and quantum mechanics, equally at ease with theory and experiment, Fermi truly was the last man who knew everything - at least about physics. But he was also a complex figure who was a part of both the Italian Fascist Party and the Manhattan Project, and a less-than-ideal father and husband who nevertheless remained one of history's greatest mentors.

The 20th century gave us two great theories of physics. The general theory of relativity describes the behavior of very large things, and quantum theory the behavior of very small things. In this landmark audiobook, John Gribbin - one of the best-known science writers of the past 30 years - presents his own version of the Holy Grail of physics, the search that has been going on for decades to find a unified "Theory of Everything" that combines these ideas into one mathematical package.

In 1922, Howard Carter peered into Tutankhamun's tomb for the first time, the only light coming from the candle in his outstretched hand. Urged to tell what he was seeing through the small opening he had cut in the door to the tomb, the Egyptologist famously replied, "I see wonderful things". Carter's fabulous discovery is just one of the many spellbinding stories told in Three Stones Make a Wall.

“Even now, nearly a century after her death, Marie Curie remains the only female scientist most people can name,” writes Dava Sobel at the opening of her shining portrait of the sole Nobel laureate decorated in two separate fields of science—Physics in 1903 with her husband, Pierre, and Chemistry by herself in 1911. And yet, as brilliant and creative as she was in the laboratory, Marie Curie was equally memorable outside it.

Today, taxonomy is viewed by many as an outdated field, one nearly irrelevant to the rest of science and of even less interest to the rest of the world. Now, as Carol Kaesuk Yoon reminds us in Naming Nature, taxonomy is critically important, because it turns out to be much more than mere science. It is also the latest incarnation of a long-unrecognized human practice that has gone on across the globe, in every culture, in every language since before time: the deeply human act of ordering and naming the living world.

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.

How many times have we looked for something and found something else? A partner, a job, an object? The same thing often happens to scientists: they design an experiment and discover the unexpected, which usually turns out to be very important. This fascinating phenomenon is called serendipity, which takes its name from the mythical Serendip, a place from which, according to a Persian fable, three princes set off to explore the world, making chance discoveries along the way.

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.

In the early 17th century, Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed - from Kepler to Newton to Einstein.

Lost Enlightenment recounts how, between the years 800 and 1200, Central Asia led the world in trade and economic development, the size and sophistication of its cities, the refinement of its arts, and, above all, in the advancement of knowledge in many fields. Central Asians achieved signal breakthroughs in astronomy, mathematics, geology, medicine, chemistry, music, social science, philosophy, and theology, among other subjects.

Drawn from historical records and current news headlines, A Taste for Poison weaves together the tales of spurned lovers, shady scientists, medical professionals, and political assassins to show how the precise systems of the body can be impaired to lethal effect through the use of poison. From the deadly origins of the gin and tonic cocktail to the arsenic-laced wallpaper in Napoleon’s bedroom, A Taste for Poison leads listeners on a fascinating tour of the intricate, complex systems that keep us alive - or don’t.

The bald eagle is regal but fearless, a bird you’re not inclined to argue with. For centuries, Americans have celebrated it as “majestic” and “noble,” yet savaged the living bird behind their national symbol as a malicious predator of livestock and, falsely, a snatcher of babies.

Although we usually think of technology as something unique to modern times, our ancestors began to create the first technologies millions of years ago in the form of prehistoric tools and weapons. Over time, eight key technologies gradually freed us from the limitations of our animal origins.

The first-ever inside look at DARPA - the Defense Advanced Research Projects Agency - the maverick and controversial group whose futuristic work has had amazing civilian and military applications, from the Internet to GPS to driverless cars

For many, the moon landing was the defining event of the twentieth century. So it seems only fitting that Norman Mailer - the literary provocateur who altered the landscape of American nonfiction - wrote the most wide-ranging, far-seeing chronicle of the Apollo 11 mission. A classic chronicle of America's reach for greatness in the midst of the Cold War, Of a Fire on the Moon compiles the reportage Mailer published between 1969 and 1970 in Life magazine
