" ... Concise explanations and descriptions - easily read and readily understood - of what we know of the chain of events and processes that connect the Sun to the Earth, with special emphasis on space weather and Sun-Climate."--Dear Reader.
This is the human story and adventures of the great scientists who measured the speed of light -- which takes eight minutes to get here from the sun, so that when we look at the stars we are looking back in time. The book narrates how, since the ancient Greeks, scientists from Faraday, Maxwell, Fizeau and Michelson struggled to understand how light can travel through the vacuum of outer space, unless it is filled with a ghostly invisible vortex Aether foam. Thereader moves from Galileo's observations of the eclipses of Jupiter's moon for navigation, to Einstein's theories and his equation E = mc2, and all the quantum weirdness which followed. Space probes,the Transit of Venus expeditions, the discovery of radio, optics and satellite navigation, and the amazing scientific instruments built to detect the Aether wind are described.
Albert Einstein knew already in the early 1900s, when he first published his famous paper about the constancy of the speed of light, that not only did this constancy imply that mass contains energy (E = m c squared), but that faster-than-light motion could lead to paradoxes -- some that seemed to involve backwards time travel. What are these paradoxes? Why is light and its speed relevant? This book will lead you through an obstacle course of conundrums and oddities, building up your understanding of how light's speed creates simple but mind-expanding paradoxes -- one conceptual riddle at a time. This is not your average popular science book. This is also not a textbook. This book takes one theme -- the universally constant speed of light -- and shows how it may appear compromised on scales from the quantum mechanics of the very small to the cosmology of the very large, and the resulting surprising implications can result. Book Review 1: "Imagine embarking on a journey to comprehend the physics of the entire universe with a guide who’s not only an expert but makes the concepts digestible and entertaining. Robert J. Nemiroff offers such a journey in Faster Than Light, a book that initially describes the speed of light, then touches on subjects as esoteric as time travel using the theory of relativity and speculation on how to send information back in time, among other subjects." -- blue ink Book Review 2: " ... takes readers on a wild ride through the ins and outs of the speed of light in this mind-bending guide. His primary approach is through a series of humorous thought experiments ... explanations are clear and concise, and most of them require only logic to sort out, making the book more accessible than similar titles." -- Booklife Book Review 3: "A fresh and joyous ride through the mind-bending puzzles at the heart of nature's most fundamental speed that remind us that the universe is strange beyond belief" -- Caleb Scharf (Author: THe Ascent of Information) Book Review 4: "Better than a new particle collider!" -- Sabine Hossenfelder (Author: Existential Physics)
A new window opens onto the cosmos... Almost every day we are challenged by new information from the outermost reaches of space. Using straightforward language, One Universe explores the physical principles that govern the workings of our own world so that we can appreciate how they operate in the cosmos around us. Bands of color in a sunlit crystal and the spectrum of starlight in giant telescopes, the arc of a hard-hit baseball and the orbit of the moon, traffic patterns on a freeway and the spiral arms in a galaxy full of stars--they're all tied together in grand and simple ways. We can understand the vast cosmos in which we live by exploring three basic concepts: motion, matter, and energy. With these as a starting point, One Universe shows how the physical principles that operate in our kitchens and backyards are actually down-to-Earth versions of cosmic processes. The book then takes us to the limits of our knowledge, asking the ultimate questions about the origins and existence of life as we know it and where the universe came from--and where it is going. Glorious photographs--many seen for the first time in these pages--and original illustrations expand and enrich our understanding. Evocative and clearly written, One Universe explains complex ideas in ways that every reader can grasp and enjoy. This book captures the grandeur of the heavens while making us feel at home in the cosmos. Above all, it helps us realize that galaxies, stars, planets, and we ourselves all belong to One Universe.
This is an adventurous story with a difference--it is soon after World War II, but Cecil (short for Cecilia) and her cousin, Rickie, are thrown into a series of adventures that have little to do with the England that they know. Inexplicably, they, and sometimes their eccentric and interesting tutor, Dominic, find themselves in another time-usually right in the middle of a dramatic, if not harrowing, moment. Every dip into time takes them farther back and each time they experience another chapter of the Church's history and teachings. At once fun and frightening, these escapades into the past take on deeper and deeper significance. Each of these three Cecil, Rickie, Dominic are faced with things from their own pasts which touch deeply upon who they are in the present and who they will choose to be in the uncertain but tantalizing future. They have much to sort out, as history-especially the history of the Christian Faith-comes unexpectedly alive.

What's faster than a cheetah?—no animal on earth can run faster. But a peregrine falcon can swoop faster than a cheetah can run. And the falcon can't compare to an airplane, a rocket, or the speed of light. Lively text and watercolors will make children laugh while they learn all about speed.
