Book Description
From #1 New York Times bestselling author Dava Sobel, the "inspiring" (People), little-known true story of women's landmark contributions to astronomy A New York Times Book Review Notable Book of 2017 Named one of the best books of the year by NPR, The Economist, Smithsonian, Nature, and NPR's Science Friday Nominated for the PEN/E.O. Wilson Literary Science Writing Award "A joy to read.” —The Wall Street Journal In the mid-nineteenth century, the Harvard College Observatory began employing women as calculators, or “human computers,” to interpret the observations their male counterparts made via telescope each night. At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges—Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates. The “glass universe” of half a million plates that Harvard amassed over the ensuing decades—through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography—enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard—and Harvard’s first female department chair. Elegantly written and enriched by excerpts from letters, diaries, and memoirs, The Glass Universe is the hidden history of the women whose contributions to the burgeoning field of astronomy forever changed our understanding of the stars and our place in the universe.

Book Description
In four new novellas, Christina Henry returns to the world of Alice and Red Queen, where magic runs as freely as secrets and blood. Lovely Creature In the New City lives a girl with a secret: Elizabeth can do magic. But someone knows her secret--someone who has a secret of his own. That secret is a butterfly that lives in a jar, a butterfly that was supposed to be gone forever, a butterfly that used to be called the Jabberwock... Girl in Amber Alice and Hatcher are just looking for a place to rest. Alice has been dreaming of a cottage by a lake and a field of wildflowers, but while walking blind in a snowstorm she stumbles into a house that only seems empty and abandoned... When I First Came to Town Hatcher wasn't always Hatcher. Once, he was a boy called Nicholas, and Nicholas fancied himself the best fighter in the Old City. No matter who fought him he always won. Then his boss tells him he's going to battle the fearsome Grinder, a man who never leaves his opponents alive... The Mercy Seat There is a place hidden in the mountains, where all the people hate and fear magic and Magicians. It is the Village of the Pure, and though Alice and Hatcher would do anything to avoid it, it lies directly in their path...

Book Description
WORST TWO OUT OF THREE When a 60 kiloton nuclear explosion destroys the University of Central Florida, terrorism is the first suspect. But terrorists don't generally leave doorways to another world in their wake. Or, rather, a generator of doorways to multiple other worlds. With time of the essence, the Secretary of Defense scrounges up the nearest physicist with a high level security clearance. With doctorates in everything from nuclear physics to electrical engineering, William Weaver, PhD, is the egghead's egghead. On the other hand, with skills in everything from mountain biking to screaming electric guitar, he's also fast enough and tough enough to survive when the alien gates start disgorging "demons." As a snap decision, he appears to be the perfect choice, smart, tough and capable. Now if he could only patch things up with his girlfriend, get his boss off his back and get his cellphone bill paid. Oh, yeah, and figure out why the heck these gates keep opening. Okay, so sometimes he's got priority issues. As the gates spread and evil aliens spread with them, it is up to Weaver and SEAL Command Master Chief Miller to find a way to stop the proliferation and close the hostile gates. The problem being that the only way they can see to save the earth is destroy it. Then there's not going to be any more girlfriends or cellphones or bosses . . . Hmmm... Okay, two out of three of those are bad. They're really, really bad. Bad on toast. Bad like the Pacific is watery. Every day a Monday, bad. One and a half at the very least. Worst two out of three. Gotta prioritize. Guess Weaver and Miller are just gonna have to save the world. At the publisher's request, this title is sold without DRM (Digital Rights Management).

Book Description
Stephen Hawking’s phenomenal, multimillion-copy bestseller, A Brief History of Time, introduced the ideas of this brilliant theoretical physicist to readers all over the world. Now, in a major publishing event, Hawking returns with a lavishly illustrated sequel that unravels the mysteries of the major breakthroughs that have occurred in the years since the release of his acclaimed first book. The Universe in a Nutshell • Quantum mechanics • M-theory • General relativity • 11-dimensional supergravity • 10-dimensional membranes • Superstrings • P-branes • Black holes One of the most influential thinkers of our time, Stephen Hawking is an intellectual icon, known not only for the adventurousness of his ideas but for the clarity and wit with which he expresses them. In this new book Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction, to explain in laymen’s terms the principles that control our universe. Like many in the community of theoretical physicists, Professor Hawking is seeking to uncover the grail of science — the elusive Theory of Everything that lies at the heart of the cosmos. In his accessible and often playful style, he guides us on his search to uncover the secrets of the universe — from supergravity to supersymmetry, from quantum theory to M-theory, from holography to duality. He takes us to the wild frontiers of science, where superstring theory and p-branes may hold the final clue to the puzzle. And he lets us behind the scenes of one of his most exciting intellectual adventures as he seeks “to combine Einstein’s General Theory of Relativity and Richard Feynman’s idea of multiple histories into one complete unified theory that will describe everything that happens in the universe.” With characteristic exuberance, Professor Hawking invites us to be fellow travelers on this extraordinary voyage through space-time. Copious four-color illustrations help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions; where black holes evaporate and disappear, taking their secret with them; and where the original cosmic seed from which our own universe sprang was a tiny nut. The Universe in a Nutshell is essential reading for all of us who want to understand the universe in which we live. Like its companion volume, A Brief History of Time, it conveys the excitement felt within the scientific community as the secrets of the cosmos reveal themselves.

Book Description
Freeman Dyson’s latest book does not attempt to bring together all of the celebrated physicist’s thoughts on science and technology into a unified theory. The emphasis is, instead, on the myriad ways in which the universe presents itself to us--and how, as observers and participants in its processes, we respond to it. "Life, like a dome of many-colored glass," wrote Percy Bysshe Shelley, "stains the white radiance of eternity." The author seeks here to explore the variety that gives life its beauty. Taken from Dyson’s recent public lectures--delivered to audiences with no specialized knowledge in hard sciences--the book begins with a consideration of the practical and political questions surrounding biotechnology. As he seeks how best to explain the place of life in the universe, Dyson then moves from the ethical to the purely scientific. The book concludes with an attempt to understand the implications of biology for philosophy and religion. The pieces in this collection touch on numerous disciplines, from astronomy and ecology to neurology and theology, speaking to the lay reader as well as to the scientist. As always, Dyson’s view of human nature and behavior is balanced, and his predictions of a world to come serve primarily as a means for thinking about the world as it is today.

Book Description
Quantum machine learning investigates how quantum computers can be used for data-driven prediction and decision making. The books summarises and conceptualises ideas of this relatively young discipline for an audience of computer scientists and physicists from a graduate level upwards. It aims at providing a starting point for those new to the field, showcasing a toy example of a quantum machine learning algorithm and providing a detailed introduction of the two parent disciplines. For more advanced readers, the book discusses topics such as data encoding into quantum states, quantum algorithms and routines for inference and optimisation, as well as the construction and analysis of genuine ``quantum learning models''. A special focus lies on supervised learning, and applications for near-term quantum devices.
