On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time.A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don't know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon--a black hole's point of no return--but will also enable scientists to test Einstein's theory under the most extreme conditions.Gravity's Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.

    Think again, for "A Man of His Word" may well be the most original fantasy you ever read. The magic is unique and applied in unexpected ways, some of which the late Lester del Rey admitted he had not met in fifty years as writer and editor. The world itself is unique - there are no humans in Pandemia, only imps, elves, gnomes, jotnar, and many more, all of whom you will recognize as "human."In MAGIC CASEMENT the tale begins gently, even slowly, with Inosolan enjoying an idyllic childhood in her father's tiny backwater kingdom, too innocent even to understand that the feelings she shares with her friend Rap are more than friendship. Mystery, menace, and the gods appear in short order, and from then on the story grows in scope and power to straddle the world, and adversity thrusts rapid maturity on Rap and Inos. Populated by unforgettable characters - Aunt Kade, Little Chicken, Doctor Sagorn, and many more - Pandemia is an incredible world of credible people and infinite surprises.

    With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    Half a century later, only robots have been to the Red Planet and our astronauts rarely venture beyond Earth orbit.Now Mars is back With everyone from Elon Musk to Ridley Scott and Donald Trump talking about it, interplanetary exploration is back on the agenda and Mars is once again the prime destination for future human expansion and colonisation. In Destination Mars, astrophysicist and science writer Andrew May traces the history of our fascination with the Red Planet and explores the science upon which a crewed mission would be based, from assembling a spacecraft in Earth orbit to surviving solar storms. With expert insight, he analyses the new space race and assesses what the future holds for human life on Mars.

     I know what you’re thinking. Sad lonely professor finds herself with five sinfully hot men who want her and suddenly life is magical and happy. I wish that was real. That’s not how this story goes. You have no idea what happens inside the gates at Shadow Wood Academy. Neither did I until I was summoned by the broody headmaster. Lured is a more accurate way to describe how Jake Windsor tricked me into walking through the academy’s doors. Humans don’t attend Shadow Wood. Not as students or teachers. I learn that the first night I’m locked in the faculty tower with no way out. Guys are howling outside my window. There is a girl walking on the roof. And I swear one kid keeps licking his lips every time he sees me. I need to escape, but there is something alluring about the men who want me to stay. I’m drawn to them, even when I know I should run for my life. Strong. Gorgeous. Sculpted muscles for miles. But did I mention they aren’t human? I have no plans to give in to them, no matter what they swear my purpose is, until I discover that without me the innocent inside the school could become orphans—or worse—snatched up by a rogue agency. I’m used to taking care of myself, and fighting for everything I have, but saving them feels impossible. I’m strong enough to stand my ground against five of the hottest men I’ve ever met if it means saving lives, right? I didn’t know destiny could be so tempting or so dangerous. Get ready to sink your teeth into this full-length reverse harem paranormal fantasy academy romance about the adults who run the school. Shadow Wood Academy Chronicles Book One is the first in a series with a smart, independent heroine and her five scorching hot men.

    "Everyone has talked about science and religion . . . but Mitchell has really dug into the main paradoxical issues and comes up with a resolving viewpoint".--Harold E. Puthoff, Ph.D.

    Every technology we rely on today was created by the human mind, seeking to understand the universe around us. Scientific knowledge is our most precious possession, and our future will be shaped by the breakthroughs to come. In this personal and fascinating work, Neil Turok, Director of the Perimeter Institute for Theoretical Physics, explores the transformative scientific discoveries of the past three centuries -- from classical mechanics, to the nature of light, to the bizarre world of the quantum, and the evolution of the cosmos. Each new discovery has, over time, yielded new technologies causing paradigm shifts in the organization of society. Now, he argues, we are on the cusp of another major transformation: the coming quantum revolution that will supplant our current, dissatisfying digital age. Facing this brave new world, Turok calls for creatively re-inventing the way advanced knowledge is developed and shared, and opening access to the vast, untapped pools of intellectual talent in the developing world. Scientific research, training, and outreach are vital to our future economy, as well as powerful forces for peaceful global progress.

    

    A starry night is one of nature's most magical wonders, yet in our artificially lit world, three-quarters of Americans' eyes never switch to night vision, and most no longer experience true darkness. In The End of Night, Paul Bogard restores awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art.From Las Vegas's Luxor Beam (the brightest single spot on this planet) to nights so starlit the sky looks like snow, Bogard blends personal narrative, natural history, science, and history to shed light on the importance of darkness--what we've lost, what we still have, and what we might regain--and the simple ways we can reduce the brightness of our nights tonight.
