Book Description
The Philip K. Dick Award-winning saga of humankind’s next five million years: “Mind-stretching science fiction at its boldest.” —Orlando Sentinel And everywhere the Humans went, they found life . . . This dazzling future history, the most ambitious and exciting since Asimov’s classic Foundation saga, tells the story of Humankind—all the way to the end of the Universe itself. Here, in luminous and vivid narratives spanning five million years, are the first Poole wormholes spanning the solar system; the conquest of Human planets by Squeem; GUTships that outrace light; the back-time invasion of the Qax: the mystery and legacy of the Xeelee, and their artifacts as large as small galaxies; photino birds and Dark Matter; and the Ring, where Ghost, Human, and Xeelee contemplate the awesome end of Time. “It’s old-fashioned 1950s-style science fiction . . . and it’s also lots of fun.” —Cleveland Plain Dealer “Enormously impressive.” —Locus

Book Description
Approach your problems from the It isn't that they can't see the solution. right end and begin with the answers. It is that they can't see the problem. Then one day, perhaps you will find the final question. G. K. Chesterton. The Scandal of Father Brown 'The point of a Pin'. 'The Hermit Clad in Crane Feathers' in R. van Gulik's The Chinese Maze Murders. Growing specialization and diversification have brought a host of monographs and textbooks on increasingly specialized topics. However, the 'tree' of knowledge of mathematics and related fields does not grow only by putting forth new branches. It also happens, quite often in fact, that branches which were thought to be completely disparate are suddenly seen to be related. Further, the kind and level of sophistication of mathematics applied in various sciences has changed drastically in recent years: measure theory is used (non trivially) in regional and theoretical economics; algebraic geometry interacts with physics; the Minkowsky lemma, coding theory and the structure of water meet one another in packing and covering theory; quantum fields, crystal defects and mathematical programming profit from homotopy theory; Lie algebras are relevant to filtering; and prediction and electrical engineering can use Stein spaces. And in addition to this there are such new emerging subdisciplines as 'experimental mathematics', 'CFD', 'completely integrable systems', 'chaos, synergetics and large-scale order', which are almost impossible to fit into the existing classification schemes. They draw upon widely different sections of mathematics.

Book Description
This book, now in its second edition, provides an introductory course on theoretical particle physics with the aim of filling the gap that exists between basic courses of classical and quantum mechanics and advanced courses of (relativistic) quantum mechanics and field theory. After a concise but comprehensive introduction to special relativity, key aspects of relativistic dynamics are covered and some elementary concepts of general relativity introduced. Basics of the theory of groups and Lie algebras are explained, with discussion of the group of rotations and the Lorentz and Poincaré groups. In addition, a concise account of representation theory and of tensor calculus is provided. Quantization of the electromagnetic field in the radiation range is fully discussed. The essentials of the Lagrangian and Hamiltonian formalisms are reviewed, proceeding from systems with a finite number of degrees of freedom and extending the discussion to fields. The final four chapters are devoted to development of the quantum field theory, ultimately introducing the graphical description of interaction processes by means of Feynman diagrams. The book will be of value for students seeking to understand the main concepts that form the basis of contemporary theoretical particle physics and also for engineers and lecturers. An Appendix on some special relativity effects is added.

Book Description
Michael Poole finds himself in a very strange landscape . . . This is the centre of the Galaxy. And in a history without war with the humans, the Xeelee have had time to built an immense structure here. The Xeelee Belt has a radius ten thousand times Earth's orbital distance. It is a light year in circumference. If it was set in the solar system it would be out in the Oort Cloud, among the comets - but circling the sun. If it was at rest it would have a surface area equivalent to about thirty billion Earths. But it is not at rest: it rotates at near lightspeed. And because of relativistic effects, distances are compressed for inhabitants of the Belt, and time drastically slowed. The purpose of the Belt is to preserve a community of Xeelee into the very far future, when they will be able to tap dark energy, a universe-spanning antigravity field, for their own purposes. But with time the Belt has attracted populations of lesser species, here for the immense surface area, the unending energy flows. Poole, Miriam and their party, having followed the Ghosts, must explore the artefact and survive encounters with its strange inhabitants - before Poole, at last, finds the Xeelee who led the destruction of Earth...

Book Description
Timelike Infinity: the strange region at the end of time where the Xeelee, owners of the universe, are waiting... The second novel in Stephen Baxter's Xeelee sequence. First there were good times: humankind reached glorious heights, even immortality. Then there were bad times: Earth was occupied by the faceless, brutal Qax. Immortality drugs were confiscated, the human spirit crushed. Earth became a vast factory for alient foodstuffs. Into this new dark age appears the end of a tunnel through time. Made from exotic matter, it is humanity's greatest engineering project in the pre-Qax era, where the other end of the tunnel remains anchored near Jupiter. When a small group of humans in a makeshift craft outwit the Qax to escape to the past through the tunnel, it is not to warn the people of Earth against the Qax, who are sure to follow them. For these men and women from the future are themselves dangerous fanatics in pursuit of their own bizarre quantum grail. Michael Poole, architect of the tunnel, must boldly confront the consequences of his genius.

Book Description
Stephen Baxter's highly acclaimed first novel and the beginning of his stunning Xeelee Sequence finally enters the SF Masterwork series! A spaceship from Earth accidentally crossed through a hole in space-time to a universe where the force of gravity is one billion times as strong as the gravity we know. Somehow the crew survived, aided by the fact that they emerged into a cloud of gas surrounding a black hole, which provided a breathable atmosphere. Five hundred years later, their descendants still struggle for existence, divided into two main groups. The Miners live on the Belt, a ramshackle ring of dwellings orbiting the core of a dead star, which they excavate for raw materials. These can be traded for food from the Raft, a structure built from the wreckage of the ship, on which a small group of scientists preserve the ancient knowledge which makes survival possible. Rees is a Miner whose curiosity about his world makes him stow away on a flying tree - just one of the many strange local lifeforms - carrying trade between the Belt and the Raft. And what he finds will change his world...

Book Description
This textbook is intended to be used in an introductory course in quantum field theory. It assumes the standard undergraduate education of a physics major and it is designed to appeal to a wide array of physics graduate students, from those studying theoretical and experimental high energy physics to those interested in condensed matter, optical, atomic, nuclear and astrophysicists. It includes a thorough development of the field theoretic approach to nonrelativistic many-body physics as a step in developing a broad-based working knowledge of some of the basic aspects of quantum field theory. It presents a logical, step by step systematic development of relativistic field theory and of functional techniques and their applications to perturbation theory with Feynman diagrams, renormalization, and basic computations in quantum electrodynamics.
