Why does a harpsichord sound different from a piano? For that matter, why does middle C on a piano differ from middle C on a tuning fork, a trombone, or a flute? "Good Vibrations" explains in clear, friendly language the out-of-sight physics responsible not only for these differences but also for the whole range of noises we call music.

The physical properties and history of sound are fascinating to study. Barry Parker's tour of the physics of music details the science of how instruments, the acoustics of rooms, electronics, and humans create and alter the varied sounds we hear. Using physics as a base, Parker discusses the history of music, how sounds are made and perceived, and the various effects of acting on sounds. In the process, he demonstrates what acoustics can teach us about quantum theory and explains the relationship between harmonics and the theory of waves.

Peppered throughout with anecdotes and examples illustrating key concepts, this invitingly written book provides a firm grounding in the actual and theoretical physics of music.

On the desolate, snow-topped peak of the highest mountain in Hawaii the view of the heavens is truly breathtaking. Since the "discovery" of Mauna Kea in 1963, astronomers worldwide have been vying for the opportunity to stargaze from its vantage point. Nine domes now stand on the peak, making this the world's largest observatory complex. Each dome is the brainchild of extraordinary scientists - pioneers who, amidst fierce competition and frigid, treacherous conditions - fought for their dreams to build the largest, most magnificent telescopes on Earth. Barry Parker, award-winning science writer, relates the intriguing stories of the founding of this observatory complex and goes on to interview some of the great astronomers of our time as they work at this inspiring site. Bringing the public for the first time into the rarefied air of the control rooms, Parker describes what marvelous challenges these astronomers pursue, night after night, through these massive telescopes. Using brilliant, colorful images from the world's most powerful infrared telescopes and data taken by the enormous Keck telescope - the largest in the world - the scientists at Mauna Kea capture visions of the most distant galaxies ever seen, and use them to look deeply into our past to try to determine our future. Through imagination and genius, the scientists at Mauna Kea have made significant strides in formulating answers to the most fascinating astronomical questions. What can the exploding galaxies in the outer reaches of space tell us about our universe in its infancy? Could the enormous black holes at the cores of galaxies actually be "seeds," central to forming these vast systems of stars? Will our universe, like a dying star, come to an end, and, if so, what dramatic events will lead to this fate? Parker clearly and eloquently explains the theories of these astronomers and describes one of their most ambitious efforts-the quest of finding life in other galaxies. Parker, whose earlier work The New York Times Book Review called "physics for poets," has penned a new masterpiece. This unforgettable book evokes the excitement of living and working at this exquisite site and dares us to imagine the awesome forces that power and shape our universe.

Thirty years ago Albert Einstein died, his dream of a theory that would unify the universe unfulfilled. He spent the last decades of his life searching for such a theory-a theory that would explain everything from elementary particles and their interac tions to the overall structure of the universe. But he failed, not because he didn't try hard enough, but because the attempt was ahead of its time. When Einstein worked on the problem liter ally nothing was known about black holes, white holes, sin gularities, the Big Bang explosion and the early universe, quarks, gauge invariance, and weak and strong nuclear forces. Today we know that all these things are important in relation to a unified theory, and that they must be incorporated in and explained by such a theory. Thus, in a sense, our problem is much more complex today than it was in Einstein's day. But scientists have persevered and as a result we are now tan talizingly close to achieving this long-sought goal. Important breakthroughs have been made. In this book we will look at these breakthroughs and at recent unified theories-theories that go by the names supergravity, superstrings, GUTs, and twistor theory. In order to understand the problem, however, we must begin at the beginning."

For some people, driving is an art; for others, it's a science. At the Isaac Newton School of Driving, though, every car is a laboratory on wheels and every drive an exciting journey into the world of physics. As explained by renowned science writer and physics professor Barry Parker -- whose father was a car mechanic and garage owner -- almost every aspect of driving involves physics. A car's performance and handling relies on fundamental concepts such as force, momentum, and energy. Its ignition system depends on the principles of electricity and magnetism. Braking relies on friction -- yet another basic scientific concept -- and if the brakes fail, the resulting damage, too, can be predicted using physics.

Parker's first lesson describes the basic physics of driving: speed and acceleration; why you get thrown forward while braking or outward while turning; and why car advertisements boast about horsepower and torque. He goes on to discuss the thermodynamics of engines, and how they can be more fuel efficient; and what friction and traction are and how they keep a car's tires on the road, whether it's dry, wet, or icy. He also describes how simple laws of physics enable scientists to design aerodynamic cars and high-tech steering systems. Parker then explores the high-performance physics of auto racing, outlines how traffic accidents are reconstructed by police, uses chaos theory to explain why traffic jams happen, and describes what cars of the future might look like. Whether you drive a Pacer or a Porsche, The Isaac Newton School of Driving offers better -- and better-informed -- driving through physics.

The author chronicles the search for . . . a theory to explain all natural fields and their interaction with particles. . . . Lives and contributions of physicists and cosmologists, starting with the pioneers of scientific cosmology in the 19th century, are described. Topics range from Maxwell's discovery of the laws of magnetic fields to Hawking's work on black hole physics. A concluding chapter looks at the current state of unified field theory.

An accessible overview of the evolution and development of our universe--from the Big Bang to cosmic strings.

"From award-winning science writer Barry Parker, the only book to consider chaos theory in all areas of astronomy. "

In this text, science writer Barry Parker takes on one of the most fascinating and fantastical aspects of modern quantum theory - time travel. From the stuff of fiction to Einstein's theory of relativity and Hawking's view of the universe, time travel has captured modern man's excitement and been as much talked about as space travel.

James Bond would have died a thousand deaths if not for Q, the genius behind the pen grenades and weaponized sports cars that have helped Britain's most famous secret agent cheat death in twenty films. Here Barry Parker demonstrates how science and technology have been as important to 007 as good looks, shaken martinis, and beautiful women. Using entertaining sketches and nontechnical language, Parker explains the basic physics behind the gadgets, cars, and stunts in a number of Bond films, from the jet packs in Thunderball to the dynamics of daredevil bungee jumping in GoldenEye. If you've ever wondered whether the laser could have actually cut Bond in half ( Goldfinger), if a wristwatch could really unzip a woman's dress ( Live and Let Die), or whether your car could do the 360-degree barrel roll from The Man with the Golden Gun, this book is for you.
