Galileo’s Dialogue Concerning the Two Chief World Systems compares the Copernican or Heliocentric system with the Ptolemaic or Peripatetic, system of the cosmos. Published in Florence in 1632, it resulted in him being tried before the Inquisition. Using the dialogue form, Galileo masterfully shows the truth of the Copernican system that the Earth revolves around the Sun. The Dialogue is one of the most important treatises ever written. A work of supreme clarity and accessibility, it remains as accessible now as when it was published.

The Narthani, a militant realm who believe their manifest destiny is to rule the entire planet, Anyar, plan to absorb Caedellium into their empire. Yozef Kolsko (a.k.a. Joe Colsco) works to find ways to increase the chances of resistance to the Narthani's planned conquest. The enemy is coming. The odds seem overwhelming, and it will take all Yozef can do, the courage of his new people, and luck, to survive.

Ripples in Spacetime is an engaging account of the international effort to complete Einstein's project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe's structure and origin. The quest for gravitational waves involved years of risky research and many personal and professional struggles that threatened to derail one of the world's largest scientific endeavors.

This is the story of a unique American hero who came of age as an astronaut during the few dramatic years when man reached the moon. Cernan's career spanned the entire Apollo program, from the tragic fire that killed three of his comrades on Apollo 1, through the moment when he left man's last footprint on the moon as commander of Apollo 17.

In the most authoritative book ever written about Apollo, David Whitehouse reveals the true drama behind the mission, telling the story in the words of those who took part - based around exclusive interviews with the key players. This enthralling book takes us from the early rocket pioneers to the shock America received from the Soviets' launch of the first satellite, Sputnik; from the race to put the first person into space, through President Kennedy's enthusiasm and later doubts, to the astronauts' intense competition to leave the first footprint.

Her Space, Her Time shares the stories of women in physics and astronomy whose work expanded scientific understanding yet whose accomplishments are often overlooked—creating a thrilling account of scientific discovery, inspirational leadership and persistence in the face of overwhelming challenges. In shaping her narrative around the science that fascinated them and the social context in which they worked, award-winning quantum physicist Shohini Ghose champions these remarkable women’s contributions, which loom even larger given the misogyny and discrimination they faced.

Near the end of the Apollo 15 mission, David Scott and fellow moonwalker James Irwin conducted a secret ceremony unsanctioned by NASA: they placed on the lunar soil a small tin figurine called The Fallen Astronaut, along with a plaque bearing a list of names. By telling the stories of those sixteen astronauts and cosmonauts who died in the quest to reach the moon between 1962 and 1972, this book enriches the saga of humankind's greatest scientific undertaking, Project Apollo, and conveys the human cost of the space race.

For at least 20,000 years, we have led not just an earthly existence, but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are - our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.

Are you curious about the future of computing but confused about where to start? Are you fascinated by the quantum buzz but intimidated by dense academic jargon? I'm here to guide you through the fascinating universe of quantum tech, in the simplest way possible. Whether you're a tech enthusiast, software developer, eager student, or an innovator at heart, this book is tailored for minds like yours. I've translated qubits, quantum gates, and superposition in a refreshingly easy way, so you don't need a PhD to come along for the ride.

Lewis Deathstalker has succeeded at the impossible: he's found Owen Deathstalker, presumed dead for the last two hundred years. Owen's return strikes a crippling blow to the Empire as his military joins the rebellion. But Owen himself has a larger mission. He - and according to prophecy, he alone - must travel back in time to stop the steadily advancing Terror before the galaxy is destroyed, leaving his descendant Lewis in command of the growing rebel army. Even as Emperor Finn Durandal's empire is on the brink of annihilation from the Terror, he will do anything to retain power.

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: Observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria.

The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos. Exhibiting a breadth of intellect nothing short of astounding, Sagan presents his views on a wide range of topics, including the likelihood of intelligent life on other planets, creationism and so-called intelligent design.

Walk in Hell is the incredible second book of best-selling author Harry Turtledove’s alternate history tetralogy of World War I, The Great War. The first book, American Front, was chosen by Publishers Weekly as one of the Best Books of 1998.

In this startlingly vivid portrait of a world torn apart by war and strife, the Confederate States of America ally with Britain and France, while the United States sides with Germany in a World War I that might have been.

On a moonless night in January 1991, a dozen US aircraft appeared in the skies over Baghdad. To the Iraqi air defenses, the planes seemed to come from nowhere. Each aircraft was more than 60 feet in length and with a wingspan of 40 feet, yet its radar footprint was the size of a ball bearing. Here was the first extensive combat application of Stealth technology. And it was devastating.

Buckle up for a joy ride through physics, chemistry, biology, geology, and astronomy. Drawing on conversations with hundreds of the world's top scientists and her own work as an award-winning science writer, Natalie Angier does the impossible: she makes science fascinating and seriously fun, even for those of us who, in Angier's words, "still can't tell the difference between a proton, a photon, and a moron".

NASA’s history is a familiar story, one that typically peaks with Neil Armstrong taking his small step on the Moon in 1969. But America’s space agency wasn’t created in a vacuum. It was assembled from pre-existing parts, drawing together some of the best minds the non-Soviet world had to offer. Breaking the Chains of Gravity tells the story of America’s nascent space program, its scientific advances, its personalities and the rivalries it caused between the various arms of the US military.

Digital Apollo examines the design and execution of each of the six Apollo moon landings, drawing on transcripts and data telemetry from the flights, astronaut interviews, and NASA's extensive archives. Mindell's exploration of how human pilots and automated systems worked together to achieve the ultimate in flight - a lunar landing - traces and reframes the debate over the future of humans and automation in space.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete.
