The grid is an accident of history and of culture, in no way intrinsic to how we produce, deliver and consume electrical power. Yet this is the system the United States ended up with, a jerry-built structure now so rickety and near collapse that a strong wind or a hot day can bring it to a grinding halt. The grid is now under threat from a new source: renewable and variable energy, which puts stress on its logics as much as its components.

The story of the bullet-shaped SpaceShipOne and the other teams in the hunt is an extraordinary tale of making the impossible possible. It is driven by outsized characters - Burt Rutan, Richard Branson, John Carmack, Paul Allen - and obsessive pursuits. In the end, as Diamandis dreamed, the result wasn't just a victory for one team; it was the foundation for a new industry and a new age.

You are reading the word now right now. But what does that mean? What makes the ephemeral moment "now" so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of now. Equally puzzling: Why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion.

Was there a beginning of time? Could time run backwards? Is the universe infinite, or does it have boundaries? These are just some of the questions considered in an internationally acclaimed masterpiece by one of the world's greatest thinkers. It begins by reviewing the great theories of the cosmos, from Newton to Einstein, before delving into the secrets which still lie at the heart of space and time, from the big bang to black holes, via spiral galaxies and strong theory.

James Gleick's story begins at the turn of the 20th century, with the young H. G. Wells writing and rewriting the fantastic tale that became his first book, an international sensation: The Time Machine. A host of forces were converging to transmute the human understanding of time, some philosophical and some technological - the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks.

Have you ever wondered what it would be like to find yourself strapped to a giant rocket that's about to go from zero to 17,500 miles per hour? Or to look back on Earth from outer space and see the surprisingly precise line between day and night? Or to stand in front of the Hubble Space Telescope, wondering if the emergency repair you're about to make will inadvertently ruin humankind's chance to unlock the universe's secrets? Mike Massimino has been there, and in Spaceman he puts you inside the suit.

I have had the wonderful privilege of introducing Einstein's theory of relativity to thousands of college students in my Introduction to Philosophy courses at Mt. San Antonio College and in my upper division course on Science and Religion at California State University, Long Beach. Although Einstein's concept is difficult to grasp at first, given enough time and study it becomes easier to understand over time.

From the best-selling author of Seven Brief Lessons on Physics comes a new audiobook about the mind-bending nature of the universe. What are time and space made of? Where does matter come from? And what exactly is reality? Scientist Carlo Rovelli has spent his whole life exploring these questions and pushing the boundaries of what we know. Here he explains how our image of the world has changed throughout centuries.

As C.P. Snow lamented in his now famous essay, "Two Cultures", education is too often arbitrarily divided between the sciences and the humanities, as if each were acrimoniously divorced parents who wished never to speak again to each other. What do physics and psychology have in common, some may ask. Or, what does chemistry have to do with sociology?

Widely considered the greatest genius of all time, Albert Einstein revolutionized our understanding of the cosmos with his general theory of relativity and helped to lead us into the atomic age. Yet in the final decades of his life, he was also ignored by most working scientists, his ideas opposed by even his closest friends.

In Calculating the Cosmos, Ian Stewart presents an exhilarating guide to the cosmos, from our solar system to the entire universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it's all going to end. He considers parallel universes, the fine-tuning of the cosmos for life, what forms extraterrestrial life might take, and the likelihood of life on Earth being snuffed out by an asteroid.

In June of 1916, Albert Einstein published his ambitious paper proposing the existence of gravitational waves. In 2016, Einstein's 100-year-old theory was proven correct when scientists detected ripples in the fabric of space. Einstein and Relativity: A Conversation by Paul Rudd and Brian Greene celebrates this achievement, with Greene and Rudd sitting down to talk about string theory, relativity, and the discovery of gravitational waves.

Best-selling author, superstar physicist, and cofounder of the World Science Festival Brian Greene (The Elegant Universe, The Fabric of the Cosmos) and an ensemble cast led by award-winning actor Paul Rudd (Ant-Man) perform this dramatic story tracing Albert Einstein's discovery of the general theory of relativity.

This lively and informative exploration of the heart offers a perfect mix of medical fact and amusing anecdote. A prospective cardiologist and former paramedic - as well as one of Germany's most successful science-slammers - von Borstel relates his own experiences to provide a personal insight into the human side of heart medicine while clearly explaining the science behind cardiac disease and healthcare for the heart.

A system can describe what we see (the solar system), operate a computer (Windows 10), or be made on a page (the 14 engineered lines of a sonnet). In this book, Clifford Siskin shows that system is best understood as a genre - a form that works physically in the world to mediate our efforts to understand it. Indeed, many Enlightenment authors published works they called "system" to compete with the essay and the treatise.

An exploration of space and time and a journey of discovery through 13 of the most fascinating Christmas Lectures given at the Royal Institution of Great Britain over the last 200 years. Started at the Royal Institution (RI) in 1825 by Michael Faraday, the Christmas Lectures have been broadcast on television since the 1960s and have formed part of the British Christmas tradition for generations.

What is it that helps both scorpions and cyclists to survive? What do raw eggs and gyroscopes have in common? And why does it matter? In an age of string theory, fluid dynamics and biophysics, it can seem as if the science of our world is for only specialists and academics. Not so, insists Helen Czerski - and in this sparkling new audiobook she explores the patterns and connections that illustrate the grandest theories in the smallest everyday objects and experiences.

In Beyond Earth, the authors offer groundbreaking research and argue persuasively that not Mars but Titan - a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy, where we will be able to fly like birds in the minimal gravitational field - offers the most realistic and thrilling prospect of life without support from Earth.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.
