Linear Synchronous Motors: Transportation and Automation Systems provides a comprehensive treatment of all types of brushless LSMs-their construction, electromagnetic effects, control, and applications. It explains the physics of hard magnetic materials, discusses permanent magnet and superconducting excitation systems, and addresses applications in factory automation and high-speed transportation systems. LSMs have better performance and higher power density than their induction counterparts, and they can operate with a larger mechanical clearance between their stationary and moving part. Paying equal attention to the design and the applications, Linear Synchronous Motors offers a unique opportunity to master the inner workings of LSMs, discover new research results, and keep abreast of their emerging applications.

The Amateur Astronomer

Patrick Moore, «The Amateur Astronomer (Patrick Moore's Practical Astronomy)»

Springer | ISBN: 1852338784 | 12 edition (October 11, 2005) | 293 pages | PDF | 8 Mb

This 2000 Edition of Sir Patrick Moore's classic book has been completely revised in the light of changes in technology. Not only do these changes include commercially available astronomical telescopes and software, but also what we know and understand about the universe. There are many new photographs and illustrations. Writing in the easy-going style that made him famous as a writer and broadcaster, Sir Patrick introduced astronomy and amateur observing together, so that his reader gets an idea of what he is observing at the same time as how to observe. Almost half the book is Appendices. These are hugely comprehensive and provide hints and tips, as well as data (year 2000 onwards) for pretty well every aspect of amateur astronomy. This is probably the only book in which all this information is collected in one place.

A First Course in String Theory by Barton Zwiebach (Author)
Hardcover: 578 pages | Publisher: Cambridge University Press (June 28, 2004) | English | ISBN-10: 0521831431 | ISBN-13: 978-0521831437

Book Description
An accessible introduction to string theory, this book provides a detailed and self-contained demonstration of the main concepts involved. The first part deals with basic ideas, reviewing special relativity and electromagnetism while introducing the concept of extra dimensions. D-branes and the classical dynamics of relativistic strings are discussed next, and the quantization of open and closed bosonic strings in the light-cone gauge, along with a brief introduction to superstrings. The second part begins with a detailed study of D-branes followed by string thermodynamics. It discusses possible physical applications, and covers T-duality of open and closed strings, electromagnetic fields on D-branes, Born/Infeld electrodynamics, covariant string quantization and string interactions. Primarily aimed as a textbook for advanced undergraduate and beginning graduate courses, it will also be ideal for a wide range of scientists and mathematicians who are curious about string theory.

Review

"Zwiebach makes an explicit attempt to be accessible to undergraduate students." Donald Marolf, University of California Santa Barbara, American Journal of Physics "There is a great curiosity about string theory, not only among physics undergraduates but also among professional scientists outside of the field. This audience needs a text that goes much further than the popular accounts but without the full technical detail of a graduate text.Zwiebach's book meets this need in a clear and accessible manner. It is well-grounded in familiar physical concepts, and proceeds through some of the most timely and exciting aspects of the subject." Professor Joseph Polchinski, University of California, Santa Barbara "A refreshingly different approach to string theory that requires remarkably little previous knowledge of quantum theory or relativity. This highlights fundamental features of the theory that make it so radically different from theories based on point-like particles. This book makes the subject amenable to undergraduates but it will also appeal greatly to beginning researchers who may be overwhelmed by the standard textbooks. Furthermore, all of this is accomplished with great elegance in a single volume." Professor Michael Green, University of Cambridge "Barton Zwiebach has written a careful and thorough introduction to string theory that is suitable for a full-year course at the advanced undergraduate level. There has been much demand for a book about string theory at this level, and this one should go a long way towards meeting that demand." Professor John Schwarz, California Institute of Technology "Zwiebach every now and then takes some nice and surprising angles on well-known and lesser-known results, so even if you are already way past the basics, it might be well worth taking a look at this book."

Quantum Field Theory in a Nutshell  A. Zee (Author)

Hardcover: 536 pages | Publisher: Princeton University Press (March 10, 2003) | Language: English | ISBN-10: 0691010196 | ISBN-13: 978-0691010199

Description: This book is arguably the most comprehensive introduction to Quantum Field Theory, a subject that seems rather formidable at first. This book makes it accessible to a wider audience. It starts with the Path Integral Formalism First instead of the traditional canonical formalism. It makes the transition to field theory and derivation of the Feynman rules a bit easier. It is meant for people who want learn QFT by themselves after a course on Quantum Mechanics.

Publisher:Springer (2005-12-22) | ISBN-10: 0387253645 | PDF | 4.3 Mb | 262 pages

The topic of the inverse problems is of substantial and rapidly growing interest for many scientists and engineers. The second edition covers most important recent developments in the field of inverse problems, describing theoretical and computational methods, and emphasizing new ideas and techniques. It also reflects new changes since the first edition, including some corrections. This edition is considerably expanded, with some concepts such as pseudo-convexity, and proofs simplified. New material is added to reflect recent progress in theory of inverse problems.

This book is intended for mathematicians working with partial differential equations and their applications, and physicists, geophysicists and engineers involved with experiments in nondestructive evaluation, seismic exploration, remote sensing and tomography.

Brian Greene, «The Fabric of the Cosmos: Space, Time, and the Texture of Reality»
Knopf | ISBN: 0375412883 | 1 edition (February 10, 2004) | 576 pages | PDF | 2 Mb

" 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

Principles of Quantum Mechanics by R. Shankar (Author)

Publisher: Springer; 2 edition (September 1, 1994) | 694 pages |Language: English | ISBN-10: 0306447908 | ISBN-13: 978-0306447907

Review

`An excellent text....The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succint manner.' - American Scientist, from a review of the First Edition

Book Description

Reviews from the First Edition:

"An excellent text ... The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succinct manner." (American Scientist)

"No matter how gently one introduces students to the concept of Dirac's bras and kets, many are turned off. Shankar attacks the problem head-on in the first chapter, and in a very informal style suggests that there is nothing to be frightened of." (Physics Bulletin)

Reviews of the Second Edition:

"This massive text of 700 and odd pages has indeed an excellent get-up, is very verbal and expressive, and has extensively worked out calculational details-all just right for a first course. The style is conversational, more like a corridor talk or lecture notes, though arranged as a text. ... It would be particularly useful to beginning students and those in allied areas like quantum chemistry." (Mathematical Reviews)

R. Shankar has introduced major additions and updated key presentations in this second edition of Principles of Quantum Mechanics. New features of this innovative text include an entirely rewritten mathematical introduction, a discussion of Time-reversal invariance, and extensive coverage of a variety of path integrals and their applications. Additional highlights include:

- Clear, accessible treatment of underlying mathematics

- A review of Newtonian, Lagrangian, and Hamiltonian mechanics

- Student understanding of quantum theory is enhanced by separate treatment of mathematical theorems and physical postulates

- Unsurpassed coverage of path integrals and their relevance in contemporary physics

The requisite text for advanced undergraduate- and graduate-level students, Principles of Quantum Mechanics, Second Edition is fully referenced and is supported by many exercises and solutions. The book's self-contained chapters also make it suitable for independent study as well as for courses in applied disciplines.
