¿Como seria caer dentro de un agujero negro? ¿En que se parecen bailar un vals y contemplar una dualidad de cuerdas?La teoria de cuerdas trata de describir todas las fuerzas fundamentales de la naturaleza, hermanando conceptos tales como la gravedad y la mecanica cuantica en una sola teoria que, de momento, no esta aun probada. Rodeada de misterio y controversia, la teoria de cuerdas se vuelve menos opaca bajo la mirada de Steven S. Gubser, que nos la presenta de forma amena y entretenida.

Si hay algun fenomeno de la Fisica y la Astronomia que intriga y fascina al hombre, este es el de los agujeros negros, y fue Albert Einstein, cuando hace mas de cien anos elaboro la Teoria de la Relatividad, el primer cientifico que predijo su existencia como solucion a sus ecuaciones. Steven S. Gubser y Frans Pretorius arrojan luz sobre uno de los mayores misterios del universo a traves de ejemplos creativos y accesibles.

The goal of Essential College Physics is to provide a book focused on essential principles—a shorter, more focused book that better addresses the learning needs of today's readers while more effectively guiding them through the mastery of physics. Brevity does not need to come at the expense of reader learning. This book is designed from the ground up to be concise and focused, resulting in a book less intimidating and easier to use, with well-coordinated explanations, art, worked examples, and end-of-chapter problems. It incorporates an overarching connected approach: connecting ideas within and across chapters; connecting physics with the real world; connecting words and math; and connecting with how today's readers learn and how they use their book. In addition to providing a strong foundation that teaches physics principles, the book also focuses on building readers' problem-solving skills. The friendly, integrated approach, combined with the low price, makes Essential College Physics an invaluable book choice. Key Topics: Measurements in Physics, Motion in One Dimension, Motion in Two Dimensions, Force and Newton's Laws of Motion, Work and Energy, Momentum and Collisions, Oscillations, Rotational Motion, Gravitation, Solids and Fluids, Waves and Sound, Temperature, Thermal Expansion, and Ideal Gases, Heat, The Laws of Thermodynamics, Electric Charges, Forces, and Fields, Electric Energy, Potential, and Capacitors, Electric Current, Resistance, and Circuits, Magnetic Fields and Forces, Electromagnetic Induction and AC Circuits, Electromagnetic Waves and Special Relativity, Geometrical Optics, Wave Optics, Early Modern Physics, Atomic Physics, Nuclear Physics, Elementary Particles Market: Intended for those interested in learning the basics of college physics

Based on courses given at the universities of Texas in Austin, and California in San Diego, this book deals with the basic mechanisms that determine the dynamic evolution of classical and quantum systems. It presents, in as simple a manner as possible, the basic mechanisms that determine the dynamical evolution of both classical and quantum systems in sufficient generality to include quantum phenomena. The book begins with a discussion of Noether''s theorem, integrability, KAM theory, and a definition of chaotic behavior; it continues with a detailed discussion of area-preserving maps, integrable quantum systems, spectral properties, path integrals, and periodically driven systems; and it concludes by showing how to apply the ideas to stochastic systems. The presentation is complete and self-contained; appendices provide much of the needed mathematical background, and there are extensive references to the current literature. Problems at the ends of chapters help students clarify their understanding. In this new edition, the presentation will be brought up to date throughout, and a new chapter on open quantum systems will be added.

Superstrings - provocative, controversial, possibly untestable, but unarguably one of the most interesting and active areas of research in current physics. Called by some, "the theory of everything", superstrings may solve a problem which has eluded physicists for the past 50 years - the final unification of the two great theories of the twentieth century, general relativity and quantum field theory. Now, here is a course-tested comprehensive introductory graduate text on superstrings which stresses the most current areas of interest, not covered in other presentation, including: - string field theory - multi loops - Teichmueller spaces - conformal field theory - four-dimensional strings. The book begins with a simple discussion of point particle theory, and uses the Feynman path integral technique to unify the presentation of superstrings. Prerequisites are an aquaintance with quantum mechanics and relativity. This second edition has been revised and updated throughout.

Data assimilation is considered a key component of numerical ocean model development and new data acquisition strategies The basic concept of data assimilation is to combine real observations via estimation theory with dynamic models Related methodologies exist in meteorology geophysics and engineering Of growing importance in physical oceanography data assimilation can also be exploited in biological and chemical oceanography Such techniques are now recognized as essential to understand the role of the ocean in a global change perspective The book focuses on data processing algorithms for assimilation current methods for the assimilation of biogeochemical data strategy of model development and the design of observational data for assimilation

he book is an introductory text to the physics of Bose-Einstein condensation. This phenomenon, first predicted by Einstein in 1925, has been realized experimentally in 1995 in a remarkable series of experiments whose importance has been recognized by the award of the 2001 Nobel Prize in Physics. The condensate is actually a new state of matter, where quantum-mechanical wave functions of atoms behave as coherent matter waves in the same way as coherent light waves in the case of a laser. The authors provide a theoretical presentation of the main concepts underlying the physics of dilute atomic gases in conditions of extremely low temperatures where quantum effects play a crucial role. The main effort is devoted to discussion of the relevant theoretical aspects exhibited by these systems, such as the concept of order parameter, long range order, superfluidity and coherence. The mathematical formalism is presented in a form convenient for practical use. The book develops the theory of Bose gases starting from the pioneering Bogoliubov approach and gives special emphasis to the new physical features exhibited by non-uniform gases which are produced in the recent experiments with magnetic and optical traps. These features include the determination of the equilibrium profiles, the collective oscillations, the mechanism of the expansion of the gas after releasing the trap, the interference patterns obtained by overlapping two condensates, the rotational properties revealing the effects of superfluidity (quantized vortices, behaviour of the moment of inertia), the Josephson-like phenomena associated with the coherence of the phase, the beyond mean field phenomena exhibited by quantum gases in conditions of reduced dimensionality (1D and 2D) etc. The book also discusses the analogies and differences with the physics of "classical" superfluids like liquid helium and introduces some of the major features of trapped Fermi gases at low temperature, pointing out the consequences of superfluidity.
