Book Description
"Even though most physicists believe that the speed of light is as fast as anyone can go, Einstein's theory of special relativity does not rule out faster-than-light (FTL) travel. On the contrary, it seems to indicate that certain superluminal or FTL effects would permit us to re-experience the past: time travel would become a reality, not science fiction. Through this crack in the cosmic egg steps Herbert, a Stanford physicist and author of Quantum Reality, who summarizes clearly current speculation and theory about faster-than-light travel. Along with space warps, black holes and tachyons (hypothetical FTL particles), he looks at the so-called 'quantum connection'—an alleged force said to instantaneously link any two subatomic particles long after they have bumped into each other. Free of the woolgathering that tints much writing on the 'new physics', this brave, exciting book should send scientists back to their drawing boards; for the nonspecialist reader, it reveals a world much stranger than Star Trek."—Publishers Weekly "Original, challenging, and audacious."—San Diego Magazine

Book Description
The idea that the speed of light is a constant - at 186,000 miles per second - is one of the few scientific facts that almost everyone knows. That constant - c- also appears in the most famous of all scientific equations: e=mc2- Yet over the last few years, a small group of highly reputable young physicists have suggested that the central dogma of modern physics may not be an absolute truth - light may have moved faster in the earlier life of the universe, it may still be moving at different speeds elsewhere today. In telling the story of this heresy, and its gradual journey towards acceptance, Joao Magueijo writes as one of the three central figures in the story, introducing the reader to modern cosmology, to the implications of VSL (variable speed of light) and to the world of physicists. The initial rejection of Magueijo's ideas is beginning to give way to a reluctant acceptance that the young men may have a point - only the next few years will tell the final fate of this 'dangerous' idea.

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
What's faster than a cheetah?—no animal on earth can run faster. But a peregrine falcon can swoop faster than a cheetah can run. And the falcon can't compare to an airplane, a rocket, or the speed of light. Lively text and watercolors will make children laugh while they learn all about speed.

Book Description
This is an insightful examination of one of the essential problems of the history of science - how does elite, esoteric knowledge get read, used, modified, and owned by those outside the professional scientific community? Price focuses on one of the defining scientific ideas of the 20th century and skillfully demonstrates the many genres and styles through which it was adopted and changed.

Book Description
In 1905, Albert Einstein declared speeds greater than light to be impossible. This book describes the author’s decades-long search for the hypothetical subatomic particles known as tachyons that violate this principle. This book is a scientific detective story. The crime is speeding—that is, the possible breaking of the cosmic speed limit, namely the speed of light, as stipulated by Einstein. This detective story is also a memoir written by a member of a band of "tachyon hunters." The author’s pursuit of tachyons has been met with skepticism from most physicists, who note correctly that no such superluminal particles have ever been surely observed and that there have been many false sightings. Nevertheless, considerable circumstantial evidence for tachyons has already been published and an ongoing experiment could decide the issue in the next few years. This book is written for the general reader, containing humor and eliminating jargon whenever possible, and will also be of interest to scientists. The hunt for the tachyon will fascinate all readers who approach the study of physics with curious and open minds.

Book Description
“Venter instills awe for biology as it is, and as it might become in our hands.” —Publishers Weekly On May 20, 2010, headlines around the world announced one of the most extraordinary accomplishments in modern science: the creation of the world’s first synthetic lifeform. In Life at the Speed of Light, scientist J. Craig Venter, best known for sequencing the human genome, shares the dramatic account of how he led a team of researchers in this pioneering effort in synthetic genomics—and how that work will have a profound impact on our existence in the years to come. This is a fascinating and authoritative study that provides readers an opportunity to ponder afresh the age-old question “What is life?” at the dawn of a new era of biological engineering.

Book Description
The propagation of light in dispersive media is a subject of fundamental as well as practical importance. In recent years attention has focused in particular on how refractive index can vary with frequency in such a way that the group velocities of optical pulses can be much greater or much smaller than the speed of light in vacuum, or in which the refractive index can be negative. Treating these topics at an introductory to intermediate level, Fast Light, Slow Light and Left-Handed Light focuses on the basic theory and describes the significant experimental progress made during the past decade. The book pays considerable attention to the fact that superluminal group velocities are not in conflict with special relativity and to the role of quantum effects in preventing superluminal communication and violations of Einstein causality. It also explores some of the basic physics at the opposite extreme of very slow group velocities as well as stopped and regenerated light, including the concepts of electromagnetically induced transparency and dark-state polaritons. Another very active aspect of the subject discussed concerns the possibility of designing metamaterials in which the refractive index can be negative and propagating light is left-handed in the sense that the phase and group velocities are in opposite directions. The last two chapters are an introduction to some of the basic theory and consequences of negative refractive index, with emphasis on the seminal work carried out since 2000. The possibility that "perfect" lenses can be made from negative-index metamaterials-which has been perhaps the most controversial aspect of the field-is introduced and discussed in some detail.
