Book Description
From the big bang to black holes, this fast-paced illustrated tour of time and space for the astro-curious unlocks the science of the stars to reveal fascinating theories, surprising discoveries, and ongoing mysteries in modern astronomy and astrophysics. Before the big bang, time, space, and matter didn't exist. In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theories to explain the weird and wonderful phenomena they observed. Through these observations, we now understand concepts like the size of the universe (still expanding), the distance to the next-nearest star from earth (Alpha Centauri, 26 trillion miles) and what drives the formation of elements (nuclear fusion), planets and galaxies (gravity), and black holes (gravitational collapse). But are these cosmological questions definitively answered or is there more to discover? Oxford University astrophysicist and popular YouTube personality Dr. Becky Smethurst presents everything you need to know about the universe in ten accessible and engagingly illustrated lessons. In Space at the Speed of Light: The History of 14 Billion Years for People Short on Time, she guides you through fundamental questions, both answered and unanswered, posed by space scientists. Why does gravity matter? How do we know the big bang happened? What is dark matter? Do aliens exist? Why is the sky dark at night? If you have ever looked up at night and wondered how it all works, you will find answers--and many more questions--in this pocket-sized tour of the universe!

Book Description
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.

Book Description
INSTANT NEW YORK TIMES BESTSELLER “Most appealing... technical accuracy and lightness of tone... Impeccable.”—Wall Street Journal “A porthole into another world.”—Scientific American “Brings science dissemination to a new level.”—Science The most trusted explainer of the most mind-boggling concepts pulls back the veil of mystery that has too long cloaked the most valuable building blocks of modern science. Sean Carroll, with his genius for making complex notions entertaining, presents in his uniquely lucid voice the fundamental ideas informing the modern physics of reality. Physics offers deep insights into the workings of the universe but those insights come in the form of equations that often look like gobbledygook. Sean Carroll shows that they are really like meaningful poems that can help us fly over sierras to discover a miraculous multidimensional landscape alive with radiant giants, warped space-time, and bewilderingly powerful forces. High school calculus is itself a centuries-old marvel as worthy of our gaze as the Mona Lisa. And it may come as a surprise the extent to which all our most cutting-edge ideas about black holes are built on the math calculus enables. No one else could so smoothly guide readers toward grasping the very equation Einstein used to describe his theory of general relativity. In the tradition of the legendary Richard Feynman lectures presented sixty years ago, this book is an inspiring, dazzling introduction to a way of seeing that will resonate across cultural and generational boundaries for many years to come.

Book Description
Kirkus Star Junior Library Guild Gold Selection Mark Weston’s high-interest story and Rebecca Evans’s colorful graphics make scientific discovery the coolest thing this side of Jupiter. More than two centuries before Einstein, using a crude telescope and a mechanical timepiece, Danish astronomer Ole Romer measured the speed of light with astounding accuracy. How was he able to do this when most scientists didn’t even believe that light traveled? Like many paradigm-shattering discoveries, Romer’s was accidental. Night after night he was timing the disappearance and reappearance of Jupiter’s moon Io behind the huge, distant planet. Eventually he realized that the discrepancies in his measurements could have only one explanation: Light had a speed, and it took longer to reach Earth when Earth was farther from Jupiter. All he needed then to calculate light’s speed was some fancy geometry.

Book Description
Every family has a story. Every story, eventually, must be told. For most of their lives, Julian Perel and his sister, Paula, lived in a house cast in silence, witnesses to a father struggling with a devastating secret too painful to share. Though their father took his demons to the grave, his past refuses to rest. As adults, brother and sister struggle to find their voices. A scientist governed by numbers and logic, Julian now lives an ordered life of routine and seclusion. My father gave up his language and his homeland. But he carried his sadness with him, under his skin. It was mine now. In contrast, Paula has entered the world as eagerly as Julian retracts from it. An aspiring opera singer, she is always moving, buoyant with sound. Singing was the only gift I could offer to my father. I filled the house with music. I tried to give him joy. . . . Yet both their lives begin to change on a Wednesday, miercoles, the day that sounds like miracles. Before embarking on a European opera tour, Paula asks her housekeeper, Sola, to stay at her place--and to look after Julian in the apartment above. Yet Sola, too, has a story. I want to clean myself like the window of a house, make myself clear for things to pass through. Flat and quiet. As Paula uncovers pieces of her father's early life in Budapest and the horrifying truth of his past, Julian bears witness to Sola's story--revelations that help all three learn how to both surrender and revere the shadows that have followed them for so long. The Speed of Light is a powerful debut about three unforgettable souls who overcome the tragedies of the past to reconnect with one another and the world around them. In an extraordinary accomplishment, Elizabeth Rosner has created a novel of love and redemption that proves the pain of the untold story is far greater than even the most difficult truth.

Book Description
Philosophical foundations of the physics of space-time This concise book introduces nonphysicists to the core philosophical issues surrounding the nature and structure of space and time, and is also an ideal resource for physicists interested in the conceptual foundations of space-time theory. Tim Maudlin's broad historical overview examines Aristotelian and Newtonian accounts of space and time, and traces how Galileo's conceptions of relativity and space-time led to Einstein's special and general theories of relativity. Maudlin explains special relativity with enough detail to solve concrete physical problems while presenting general relativity in more qualitative terms. Additional topics include the Twins Paradox, the physical aspects of the Lorentz-FitzGerald contraction, the constancy of the speed of light, time travel, the direction of time, and more. Introduces nonphysicists to the philosophical foundations of space-time theory Provides a broad historical overview, from Aristotle to Einstein Explains special relativity geometrically, emphasizing the intrinsic structure of space-time Covers the Twins Paradox, Galilean relativity, time travel, and more Requires only basic algebra and no formal knowledge of physics

Book Description
Spacecraft depend on electronic components that must perform reliably over missions measured in years and decades. Space radiation is a primary source of degradation, reliability issues, and potentially failure for these electronic components. Although simulation and modeling are valuable for understanding the radiation risk to microelectronics, there is no substitute for testing, and an increased use of commercial-off-the- shelf parts in spacecraft may actually increase requirements for testing, as opposed to simulation and modeling. Testing at the Speed of Light evaluates the nation's current capabilities and future needs for testing the effects of space radiation on microelectronics to ensure mission success and makes recommendations on how to provide effective stewardship of the necessary radiation test infrastructure for the foreseeable future.

Book Description
A study of the new scientific understanding of consciousness and the mind as a fifth dimension of reality • Introduces the existence of a fifth dimension--one of mind--an inner- or hyperspace where time is transcended • Shows how the barrier of the speed of light is actually a gateway demarking the fifth dimension Since the introduction of Descartes’ dualism in the seventeenth century, the mind and the physical world have been viewed as disconnected entities. Yet qualities of mind such as awareness, purposeful action, organization, design, and even decision-making are present within the structure of matter and within the dimensions of space and time. The space-time continuum of scientists generally ignores the realm of the mind, though phenomena such as imaginary numbers, used by Einstein to combine space with time, are concepts that only exist in the mind. Marc Seifer contends that the inadequacy of four-dimensional models to account for our experience of mental phenomena points to the consciousness of the mind as a higher organizing principle, a fifth dimension where thoughts are as real and quantifiable as our familiar physical world. He shows that because thought enables us to move backward and forward through time--reflecting on the past and making plans for the future--this fifth dimension of mind breaks the laws of relativity, thereby transcending the speed of light. His extensive study of this fifth dimension ranges from relativity and ether theory to precognition, telepathy, and synchronicity, all from the perspective of the conscious universe.

Book Description
NATIONAL BESTSELLER • From one of the world’s leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes “an astonishing ride” through the universe (The New York Times) that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.
