With a foreword by Athene Donald, Professor of Experimental Physics, University of Cambridge and Master of Churchill College. Ten Women Who Changed Science tells the moving stories of the physicists, biologists, chemists, astronomers and doctors who helped to shape our world with their extraordinary breakthroughs and inventions, and outlines their remarkable achievements. These scientists overcame significant obstacles, often simply because they were women. Their science and their lives were driven by personal tragedies and shaped by seismic world events.

Story36
This is a landmark in science writing. It resurrects from the vaults of neglect the polymath Jerome Cardano, a Milanese of the 16th century. Who is he? A gambler and blasphemer, inventor and chancer, plagued by demons and anxieties, astrologer to kings, emperors and popes. This stubborn and unworldly man was the son of a lawyer and a brothel keeper but also a gifted physician and the unacknowledged discoverer of the mathematical foundations of quantum physics.

Story1
On December 16, 1947, two physicists at Bell Laboratories, John Bardeen and Walter Brattain, jabbed two electrodes into a sliver of germanium half an inch long. The electrical power coming out of that piece of germanium was 100 times stronger than what went in. In that moment, the transistor was invented and the information age began. Crystal Fire recounts the story of the transistor team at Bell Labs, led by William Shockley, who shared the Nobel Prize with Bardeen and Brattain.

Throughout the Roman Empire cities held public speeches and lectures, had libraries, and teachers and professors in the sciences and the humanities, some subsidized by the state. There even existed something equivalent to universities, and medical and engineering schools. What were they like? What did they teach? Who got to attend them? In the first treatment of this subject ever published, Dr. Richard Carrier answers all these questions and more.

At a time when many people around the world are living into their 10th decade, the longest longitudinal study of human development ever undertaken offers some welcome news for the new old age: Our lives continue to evolve in our later years and often become more fulfilling than before. Begun in 1938, the Grant Study of Adult Development charted the physical and emotional health of over 200 men, starting with their undergraduate days. The now-classic Adaptation to Life reported on the men's lives up to age 55 and helped us understand adult maturation.

A fascinating look at a bizarre, forgotten epidemic from the national best-selling author of The American Plague. In 1918, a world war raged, and a lethal strain of influenza circled the globe. In the midst of all this death, a bizarre disease appeared in Europe. Eventually known as encephalitis lethargica, or sleeping sickness, it spread worldwide, leaving millions dead or locked in institutions. Then, in 1927, it disappeared as suddenly as it arrived.

Humans are pattern-matching creatures, and astrology is our grandest pattern-matching game. In this ingenious work of history, data scientist Alexander Boxer examines a treasure trove of esoteric classical sources to expose the deep imaginative framework by which - for millennia - we made sense of our fates. Astrology, he argues, was the ancient world's most ambitious applied mathematics problem, a grand data-analysis enterprise sustained by some of history's most brilliant minds, from Ptolemy to al-Kindi to Kepler.

The Pleistocene spans a period from around 2.5 million years ago (mya) to just over 12,000 years ago, and it was an epoch of enormous change on Earth, mainly characterized by climate changes involving fluctuations between periods of extreme heat and long periods of glaciation. This period is commonly known as the Ice Age, despite the fact there were actually a number of separate periods of cold. The Pleistocene Era: The History of the Ice Age and the Dawn of Modern Humans looks at the development of the era, what life on Earth was like, and the origins of archaic humans.

Story3
Ernest Rutherford, who grew up in colonial New Zealand and came to Cambridge on a scholarship, made numerous revolutionary discoveries, among them the orbital structure of the atom and the concept of the “half-life” of radioactive materials, which led to a massive re-evaluation of the age of the Earth―previously judged just 100 million years old. Above all, perhaps, Rutherford and the young men working under him were the first to split the atom, unlocking tremendous forces―forces, as Rutherford himself predicted, that would bring us the atomic bomb.

Award-winning author and mathematician Joseph Mazur provides an engaging exploration of how the understanding of time has evolved throughout human history and offers a compelling new vision, submitting that time lives within us. Our cells, he notes, have a temporal awareness, guided by environmental cues in sync with patterns of social interaction. Listeners learn that, as a consequence of time's personal nature, a 48-hour journey on the Space Shuttle can feel shorter than a six-hour trip on the Soyuz capsule and that the Amondawa of the Amazon do not have ages.

Many of us know little about Archimedes other than his "Eureka" exclamation upon discovering that he could immerse an object in a full tub of water and measure the spillage to determine the object's weight. That seemingly simple observation not only proved to King Hieron II of Syracuse that a certain amount of silver had been used in what was supposed to be his solid-gold crown, it established the key principles of buoyancy that govern the flotation of hot-air balloons, ships, and denizens of the sea.

It was a time of bold new technology, historic moments, and international jousting on the final frontier. But it was also a time of human drama, of moments less public but no less dramatic in the lives of those who made the golden age of space flight happen. These are the moments and the lives that Into That Silent Sea captures, a book that tells the intimate stories of the men and women, American and Russian, who made the space race their own and gave the era its compelling character.

The discovery of quantum mechanics has paved the way to just about every important innovation in the last half century: it has led us to the technology that powers microwaves, iPhones, and self-driving cars and is about to trigger a computing revolution that will either spell the end of the human species or propel us to heights we've never imagined. But there's another reason that quantum mechanics is so important: it is really the only way we can understand ourselves and each other.

Ever since Carl Linnaeus's binomial system of scientific names was adopted in the 18th century, scientists have been eponymously naming organisms in ways that both honor and vilify their namesakes. This charming, informative, and accessible history examines the fascinating stories behind taxonomic nomenclature, from Linnaeus himself naming a small and unpleasant weed after a rival botanist to the recent influx of scientific names based on pop-culture icons-including David Bowie's spider, Frank Zappa's jellyfish, and Beyonce's fly.
