Book Description
From its inception in Greek antiquity, the science of optics was aimed primarily at explaining sight and accounting for why things look as they do. By the end of the seventeenth century, however, the analytic focus of optics had shifted to light: its fundamental properties and such physical behaviors as reflection, refraction, and diffraction. This dramatic shift—which A. Mark Smith characterizes as the “Keplerian turn”—lies at the heart of this fascinating and pioneering study. Breaking from previous scholarship that sees Johannes Kepler as the culmination of a long-evolving optical tradition that traced back to Greek antiquity via the Muslim Middle Ages, Smith presents Kepler instead as marking a rupture with this tradition, arguing that his theory of retinal imaging, which was published in 1604, was instrumental in prompting the turn from sight to light. Kepler’s new theory of sight, Smith reveals, thus takes on true historical significance: by treating the eye as a mere light-focusing device rather than an image-producing instrument—as traditionally understood—Kepler’s account of retinal imaging helped spur the shift in analytic focus that eventually led to modern optics. A sweeping survey, From Sight to Light is poised to become the standard reference for historians of optics as well as those interested more broadly in the history of science, the history of art, and cultural and intellectual history.

Book Description
Unraveling the Mysteries of the Night Sky. Fact-filled and image-rich guide to the principles of astronomy, its history, a host of fun facts, and helpful tips for the backyard or budding astronomers! We look to the heavens and wonder in awe. Shooting stars, constellations, planets, galaxies, and the unknown. What is out there? Who is out there? How did the stars and planets come to be? What does it all mean? The last few years have brought an explosion of information leading to serious consideration of questions once deemed crazy. Do other universes exist? Are there planets that could harbor life? From a neutron star to a black hole; from the Higgs Boson particle to cosmic strings; from the speed of light to gamma radiation; plus a universe of ideas and concepts in between, The Handy Astronomy Answer Book takes you on a journey through the history, science and the latest findings in astronomy. This book tells the story of astronomy—of the cosmos and its contents, and of humanity’s efforts throughout history to unlock its secrets and solve its mysteries. You’ll learn the answers to more than 1,000 questions on astronomy and space, including ... What is astrobiology? What is the Dresden Codex, and what does it say about Mayan astronomy? What happened between Galileo and the Catholic Church? What is the longest time that a human has been in space? What is a gamma-ray burst? How do I use a star chart to find stars and constellations? How do space and time relate to one another? What were considered to be NASA’s four great observatories in space? How do astronomers map the night sky? How many constellations are there? How has the discovery of exoplanets affected the search for extraterrestrial life? Could a moon found in a star's habitable zone support life as we know it? How will the universe end? From the basic physics and history of astronomy to using star charts, telescopes, and other helpful hints for the home astronomer, and from space mission programs to the greatest adventure of all—the search for life beyond Earth—The Handy Astronomy Answer Book includes information on virtually every topic related to outer space. Containing over 120 illustrations and photos, this book brings the wonders of our universe to life!

Book Description
'We have to shift from a mindset of shame, which sees anxiety as evidence of brokenness, to a mindset of curiosity, which recognizes that anxiety is evidence of our sensitive heart, our imaginative mind and our soul's desire to grow towards wholeness.' Three million people are thought to suffer from anxiety in the UK, and it is an issue that affects a growing number of people across all ages. For anyone troubled by obsessive thoughts, insomnia and other manifestations of anxiety, counsellor Sheryl Paul offers shelter in the storm. In The Wisdom of Anxiety, Paul reveals that anxiety, like any emotion, is a signal - a clear bodily invitation to heal and renew your trust in your choices, self-image and core values. Weaving together practical exercises with personal stories, Paul offers medication-free approaches for accessing the gifts in different kinds of anxiety, and especially the anxiety summoned by life's transitions, for example a career change, becoming parents or becoming carers for loved ones. Chapters include recognising the symptoms of anxiety, its origins, the myth of 'normal', the expectation of happiness and a timeline of healing that includes exercises for the body and mind. There are also chapters on parenting in an age of anxiety and the vulnerability of connection and relationships.

Book Description
Winner of the 2019 Phi Beta Kappa Award for Science "A valuable perspective on the most important problem of our time." —Adam Becker, NPR Light of the Stars tells the story of humanity’s coming of age as we realize we might not be alone in this universe. Astrophysicist Adam Frank traces the question of alien life from the ancient Greeks to modern thinkers, and he demonstrates that recognizing the possibility of its existence might be the key to save us from climate change. With clarity and conviction, Light of the Stars asks the consequential question: What can the likely presence of life on other planets tell us about our own fate?

Book Description
Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once — setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.
