Physics Philosophy

They say you can't teach an old dog new tricks. But what about relativity? Physics professor Chad Orzel and his inquisitive canine companion, Emmy, tackle the concepts of general relativity in this irresistible introduction to Einstein's physics. Through armchair- and sometimes passenger-seat-conversations with Emmy about the relative speeds of dog and cat motion or the logistics of squirrel-chasing, Orzel translates complex Einsteinian ideas into examples simple enough for a dog to understand.

For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders—complete with roller coasters and radar, computer networks and psychopharmaceuticals.

Perhaps the greatest physicist of the second half of the 20th century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits.

Based on the newly released personal letters of Albert Einstein, Walter Isaacson explores how an imaginative, impertinent patent clerk, a struggling father in a difficult marriage who couldn't get a teaching job or a doctorate, became the mind reader of the creator of the cosmos, the locksmith of the mysteries of the atom and the universe. His success came from questioning conventional wisdom and marveling at mysteries that struck others as mundane.

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.

The Story of the Universe was inspired by a very old idea—that the universe is one river and that galaxies, stars, planets, and people are all whirls and eddies in the universal flow, arising in the universe as naturally as whirls and eddies arise in a fast-flowing river. The universe arose once upon a time in a place that created time and space. It spread in darkness like an exploding black hole until there was light. It was pure energy in pure symmetry—almost.

Science may be known for banishing the demons of superstition from the modern world. Yet just as the demon-haunted world was being exorcized by the enlightening power of reason, a new kind of demon mischievously materialized in the scientific imagination itself. Scientists began to employ hypothetical beings to perform certain roles in thought experiments―experiments that can only be done in the imagination―and these impish assistants helped scientists achieve major breakthroughs that pushed forward the frontiers of science and technology.

In 1911, a relatively unknown physicist named Albert Einstein published his preliminary theory of gravity. But it hadn't been tested. To do that, he needed a photograph of starlight as it passed the sun during a total solar eclipse. So began a nearly decade-long quest by seven determined astronomers from observatories in four countries, who traveled the world during five eclipses to capture the elusive sight. Over the years, they faced thunderstorms, the ravages of a world war, lost equipment, and local superstitions.

The second half of the 20th century witnessed a scientific gold rush as physicists raced to chart the inner workings of the atom. The stakes were high, the questions were big, and there were Nobel Prizes and everlasting glory to be won. Many mysteries of the atom came unraveled, but one remained intractable-what Frank Close calls the "Infinity Puzzle."

Since the fall of the Soviet Union, long-suppressed information has emerged on Heisenberg’s role in the Nazi atomic bomb project. In Beyond Uncertainty, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist’s personal responsibility and guilt when serving an abhorrent military regime.

The essential guide to radiation: the good, the bad, and the utterly fascinating, explained with unprecedented clarity. Earth, born in a nuclear explosion, is a radioactive planet; without radiation, life would not exist. And while radiation can be dangerous, it is also deeply misunderstood and often mistakenly feared. Now Robert Peter Gale, M.D. - the doctor to whom concerned governments turned in the wake of the Chernobyl and Fukushima - in collaboration with medical writer Eric Lax draws on an exceptional depth of knowledge to correct myths and establish facts.

Bridging the gap between the world of science and the realm of the spiritual, Wallace, a pioneer of modern consciousness research, offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physics and philosophers with the time-honored meditative traditions of Buddhism.

End Times is a compelling work of skilled reportage that peels back the layers of complexity around the unthinkable - and inevitable - end of humankind. From asteroids and artificial intelligence to volcanic supereruption to nuclear war, veteran science reporter and TIME editor Bryan Walsh provides a stunning panoramic view of the most catastrophic threats to the human race.

Inspired by Albert Einstein's theory of relativity and Bertrand Russell and David Hilbert's pursuit of the fundamental rules of mathematics, some of the most brilliant minds of the generation came together in post-World War I Vienna to present the latest theories in mathematics, science, and philosophy and to build a strong foundation for scientific investigation. Composed of such luminaries as Kurt Gödel and Rudolf Carnap, and stimulated by the works of Ludwig Wittgenstein and Karl Popper, the Vienna Circle left an indelible mark on science.

"See for yourself!" was the clarion call of the 1600s. Natural philosophers threw off the yoke of ancient authority, peered at nature with microscopes and telescopes, and ignited the scientific revolution. Artists investigated nature with lenses and created paintings filled with realistic effects of light and shadow. The hub of this optical innovation was the small Dutch city of Delft.

Gravity is the weakest force in the everyday world, yet it is the strongest force in the universe. It was the first force to be recognised and described, yet it is the least understood. It is a 'force' that keeps your feet on the ground, yet no such force actually exists. Gravity, to steal the words of Winston Churchill, is 'a riddle wrapped in a mystery inside an enigma'. And penetrating that enigma promises to answer the biggest questions in science: what is space? What is time? What is the universe? And where did it all come from?

Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

Stephen Hawking is one of the most remarkable figures of our time, a Cambridge genius who has earned international celebrity as a brilliant theoretical physicist and become an inspiration and revelation to those who have witnessed his courageous triumph over disability. This is Hawking's life story by Kitty Ferguson, who has had special help from Hawking himself and his close associates and who has a gift for translating the language of theoretical physics for non-scientists.

Most of us are clueless when it comes to the physics that makes our modern world so convenient. What's the simple science behind motion sensors, touch screens, and toasters? How do we glide through tolls using an E-ZPass or find our way to new places using GPS? In The Physics of Everyday Things, James Kakalios takes us on an amazing journey into the subatomic marvels that underlie so much of what we use and take for granted.

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.
