Ever wonder about how light moves? What does it mean to study the smallest particles known to man? How does science measure the smallest particles in the world, such as atoms, protons, neutrons and electrons? What is ether and how did it become a source of debate in the scientific community? Studying the smallest particles known to man can be exciting work. This study of the world on the molecular level, particularly matter and energy, is the realm of Quantum Physics.

Since the beginning of human history Mars has been an alluring dream - the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. Now with the advent of a revolutionary new plan, all this has changed. Leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with engaging anecdotes. The Case for Mars is not a vision for the far future or one that will cost us impossible billions.

In this special themed collection, Melvyn Bragg is joined by guest experts including Simon Schaffer, John Gribbin, Jim Al-Khalili and Sir Martin Rees to discuss 25 of the key laws, principles and problems of physics. Here are examinations of major concepts including plasma, radiation, matter and antimatter and the Second Law of Thermodynamics, as well as discourses on historical theories such as Zeno's paradoxes, the speed of light and relativity.

A wry and compelling take on the who, how, and why of near-future colonies in space. From bone-whittling microgravity to eye-popping profits, the risks and rewards of space settlement have never been so close at hand.

On September 14, 2015, after 50 years of searching, gravitational waves were detected for the first time, and astronomy changed forever. Up until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays, and the rest. But gravitational waves - ripples in the fabric of space and time - are unrelenting, passing through barriers that stop light dead.

Increasingly, cracks are appearing in the capacity of communities, ecosystems, and landscapes to provide the goods and services that sustain our planet's well-being. The response from most quarters has been for "more of the same" that created the situation in the first place: more control, more intensification, and greater efficiency. "Resilience thinking" offers a different way of understanding the world and a new approach to managing resources. It embraces human and natural systems as complex entities continually adapting through cycles of change.

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".

Join us on a journey through how we understand the universe, from its most basic particles and forces to planets, stars, and galaxies, and back through cosmic history to the birth of the cosmos. Conflicting notions about our place in the universe are defined, defended, and critiqued from scientific, philosophical, and religious viewpoints. The authors' engaging and witty style addresses what fine tuning might mean for the future of physics and the search for the ultimate laws of nature.

A short and entertaining introduction to thermodynamics that uses real-world examples to explain accessibly an important but subtle scientific theory.

What's going on in the sky? Astronomy For Dummies takes you through the solar system, the Milky Way galaxy, and all the way to the outer reaches of the universe. You'll have stars in your eyes as you discover the basics of skywatching, planets, asteroids, black holes, and dark matter. Ponder the deep questions that keep humanity guessing, like, is there anybody out there? Two NASA-award-winning astronomers take you on a tour of outer space that will fascinate you—and, if you're a student, help you through your intro astronomy course.

Enrico Fermi is unquestionably among the greats of the world's physicists, the most famous Italian scientist since Galileo. Called "the Pope" by his peers, he was regarded as infallible in his instincts and research. His discoveries changed our world; they led to weapons of mass destruction and conversely to life-saving medical interventions. This unassuming man struggled with issues relevant today, such as the threat of nuclear annihilation and the relationship of science to politics.

Frankenstein: Or, Modern Prometheus by Mary Shelley had a huge impact on Gothic horror and science fiction genres. The name Frankenstein has become part of our everyday language, often used in derogatory terms to describe scientists who have overstepped a perceived moral line. But how did a 19-year-old woman with no formal education come up with the idea for an extraordinary novel such as Frankenstein?

Everything in the universe is made of them, including you. Like you, the elements have personalities, attitudes, talents, shortcomings, stories rich with meaning. Here you'll meet iron that rains from the heavens and noble gases that light the way to vice. You'll learn how lead can tell your future while zinc may one day line your coffin. You'll discover what connects the bones in your body with the Whitehouse in Washington, the glow of a streetlamp with the salt on your dinner table.

From the solar system to spinning tops, hurricanes to hula hoops, power plants to pendulums, one mysterious force shapes almost every aspect of our lives: spin. Despite its ubiquity, rotational force continues to baffle and surprise, and few people realize how it makes our planet habitable or how it has been tamed by engineers to make our lives more comfortable. Charting the development of engineering and technology from the earliest prehistoric drills to the gas turbine, Roland Ennos presents a riveting account of human ingenuity and the seemingly infinite ways spin affects our daily lives.

Everyone has heard the story of DNA as the story of Watson, Crick, and Rosalind Franklin, but knowing the structure of DNA was only part of a greater struggle to understand life's secrets. Life's Greatest Secret is the story of the discovery and cracking of the genetic code, the thing that ultimately enables a spiraling molecule to give rise to the life that exists all around us. This great scientific breakthrough has had far-reaching consequences for how we understand ourselves and our place in the natural world.

This book will appeal to foodies and those who are deprived of cookbooks in audio format. Molecular Gastronomy documents the sensory phenomena of eating and uses basic physics to put to bed many culinary myths. This audiobook presents pieces of conventional wisdom - such as whether it is better to make a stock by placing meat in already boiling water, or water before it is boiled - and gives its history before making scientific pronouncements.

Developed by experienced professors and professionally narrated for easy listening, this course is a great way to explore the subject of college-level physics. The audio is focused and high-yield, covering the most important topics you might expect to learn in a typical undergraduate physics course. The material is accurate, up-to-date, and broken down into bite-size sections. There are quizzes and key takeaways following each section to review questions commonly tested and drive home key points.

In When the Uncertainty Principle Goes to 11, physicist Philip Moriarty explains the mysteries of the universe's inner workings via drum beats and feedback: You'll discover how the Heisenberg uncertainty principle comes into play with every chugging guitar riff, what wave interference has to do with Iron Maiden, and why metalheads in mosh pits behave just like molecules in a gas.

How does soap know what's dirt? How do magnets work? Why do ice cubes crackle in your glass? And how can you keep them quiet? These are questions that torment us all. Now Robert L. Wolke, professor emeritus of chemistry at the University of Pittsburgh, provides definitive - and amazingly simple - explanations for the mysteries of everyday life.

Too often, textbooks obscure the beauty and wonder of outer space with tedious discourse that even Galileo would oppose.
