Future imperfect... When SG-1 encounter the Pack, a nomadic space-faring people who have fled Goa'uld domination for generations - it seems as though a trade of technologies will benefit both sides. But, someone is determined to derail the deal. With the SGC under attack, and Vice President Kinsey breathing down their necks, it's up to Colonel Jack O'Neill and his team to uncover the saboteur and save the fledgling alliance. But, unbeknownst to SG-1...

The present book is intended, as far as possible, to give an exact insight into the theory of relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics. The text is divided into three parts which deal respectively with the special theory of relativity, with the general theory of relativity, and with considerations...

At the center of Cassandra Medley's play is the controversial idea that higher concentrations of melanin in the genetic makeup of people of color make them mentally, physically, and spiritually superior. Based on the scientific studies of her ironically now-deceased father, Kalima, a fledging molecular scientist looking to come to her own has a difficult time owning his flawed research. Her mother Claire, who carry's her deceased husband's scientific...

Since prehistoric times, people have wondered how the universe works. Early scientists studied how forces affect objects and watched how heavenly bodies move. In 1687 Isaac Newton published a set of laws that described the motion of all objects, both on Earth and in the heavens. By 1900 many physicists believed only a few questions remained to be answered. But the early 1900s brought revolutionary developments in physics. One was Albert Einstein's...

In It's About Time, N. David Mermin asserts that relativity ought to be an important part of everyone's education-after all, it is largely about time, a subject with which all are familiar. The book reveals that some of our most intuitive notions about time are shockingly wrong, and that the real nature of time discovered by Einstein can be rigorously explained without advanced mathematics. This readable exposition of the nature of time as addressed...

Since the publication of Einstein's Special Theory of Relativity in 1905, the discovery of such astronomical phenomena as quasars, pulsars, and black holes — all intimately connected to relativity — has provoked a tremendous upsurge of interest in the subject.This volume, a revised version of Martin Gardner's earlier Relativity for the Million, brings this fascinating topic up to date. Witty, perceptive, and easily accessible...

"Wald's book is clearly the first textbook on general relativity with a totally modern point of view; and it succeeds very well where others are only partially successful. The book includes full discussions of many problems of current interest which are not treated in any extant book, and all these matters are considered with perception and understanding."-S. Chandrasekhar "A tour de force: lucid, straightforward, mathematically rigorous, exacting...

Based on the ideas of Einstein and Minkowski, this concise treatment is derived from the author's many years of teaching the mathematics of relativity at the University of Michigan. Geared toward advanced undergraduates and graduate students of physics, the text covers old physics, new geometry, special relativity, curved space, and general relativity. Beginning with a discussion of the inverse square law in terms of simple calculus, the treatment...

If you move at high speed, time slows down, space squashes up, and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over...
