› Find signed collectible books: 'Elegant Universe: Superstrings, Hidden Dimensions and the Quest for the Ultimate Theory'
There is an ill-concealed skeleton in the closet of physics: "As they are currently formulated, general relativity and quantum mechanics cannot both be right." Each is exceedingly accurate in its field: general relativity explains the behavior of the universe at large scales, while quantum mechanics describes the behavior of subatomic particles. Yet the theories collide horribly under extreme conditions such as black holes or times close to the big bang. Brian Greene, a specialist in quantum field theory, believes that the two pillars of physics can be reconciled in superstring theory, a theory of everything.
Superstring theory has been called "a part of 21st-century physics that fell by chance into the 20th century." In other words, it isn't all worked out yet. Despite the uncertainties--"string theorists work to find approximate solutions to approximate equations"--Greene gives a tour of string theory solid enough to satisfy the scientifically literate.
Though Ed Witten of the Institute for Advanced Study is in many ways the human hero of The Elegant Universe, it is not a human-side-of-physics story. Greene's focus throughout is the science, and he gives the nonspecialist at least an illusion of understanding--or the sense of knowing what it is that you don't know. And that is traditionally the first step on the road to knowledge. --Mary Ellen Curtin [via]

As a boy, Brian Greene read Albert Camus' The Myth of Sisyphus and was transformed. Camus, in Greene's paraphrase, insisted that the hero triumphs "by relinquishing everything beyond immediate experience." After wrestling with this idea, however, Greene rejected Camus and realized that his true idols were physicists; scientists who struggled "to assess life and to experience the universe at all possible levels, not just those that happened to be accessible to our frail human senses." His driving question in The Fabric of the Cosmos, then, is fundamental: "What is reality?" Over sixteen chapters, he traces the evolving human understanding of the substrate of the universe, from classical physics to ten-dimensional M-Theory.
Assuming an audience of non-specialists, Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. For the most part, he succeeds. His language reflects a deep passion for science and a gift for translating concepts into poetic images. When explaining, for example, the inability to see the higher dimensions inherent in string theory, Greene writes: "We don't see them because of the way we see&like an ant walking along a lily pad&we could be floating within a grand, expansive, higher-dimensional space."
For Greene, Rhodes Scholar and professor of physics and mathematics at Columbia University, speculative science is not always as thorough and successful. His discussion of teleportation, for example, introduces and then quickly tables a valuable philosophical probing of identity. The paradoxes of time travel, however, are treated with greater depth, and his vision of life in a three-brane universe is compelling and--to use his description for quantum reality--"weird."
In the final pages Greene turns from science fiction back to the fringes of science fact, and he returns with rigor to frame discoveries likely to be made in the coming decades. "We are, most definitely, still wandering in the jungle," he concludes. Thanks to Greene, though, some of the underbrush has been cleared. --Patrick O'Kelley [via]

› Find signed collectible books: 'The Meaning Of Relativity: Including the Relativistic Theory of the Non-Symmetric Field'
In 1921, a young Albert Einstein traveled to America to give four lectures at Princeton University, paving the way for a more complete acceptance of his theory of general relativity. These lectures are published together as The Meaning of Relativity, and were revised with each new edition until Einstein's death. Despite Einstein's profession that he thought without using words, his examples and descriptions of the relativistic world he perceived are clear and easy to follow. Unfortunately for nontechnical readers, his presentation requires deep diversions into mathematics often enough to break up the flow of his narrative, and they may find this rough terrain. But for the mathematically sophisticated or the devoted scientific historian, these lectures are profoundly illuminating--Einstein's bright, quiet genius shines through in the simplicity and economy of his writing. Two appendices follow the lectures: the first covers advances and experimental verifications after 1921; the second, "Relativistic Theory of the Non-Symmetric Field," was Einstein's last scientific paper. The Meaning of Relativity documents a revolution in progress and yields to the careful student deeper truths than those found in physics textbooks. --Rob Lightner [via]
