When the downtrodden animals of Manor Farm overthrow their master, Mr Jones, and take over the farm themselves, they imagine it is the beginning of a life of freedom and equality. But gradually a cunning, ruthless elite among them, masterminded by the pigs Napoleon and Snowball, starts to take control. Soon the other animals discover that they are not all as equal as they thought, and find themselves hopelessly ensnared as one form of tyranny is replaced with another. Orwell's chilling 'fairy story' is a timeless and devastating satire of idealism betrayed by power and corruption.

<p>Present-day elliptical, spiral and irregular galaxies are large systems made of stars, gas and dark matter. Their properties result from a variety of physical processes that have occurred during the nearly fourteen billion years since the Big Bang. This comprehensive textbook, which bridges the gap between introductory and specialized texts, explains the key physical processes of galaxy formation, from the cosmological recombination of primordial gas to the evolution of the different galaxies that we observe in the Universe today. </p><p>In a logical sequence, the book introduces cosmology, illustrates the properties of galaxies in the present-day Universe, then explains the physical processes behind galaxy formation in the cosmological context, taking into account the most recent developments in this field. The text ends on how to find distant galaxies with multi-wavelength observations, and how to extract the physical and evolutionary properties based on imaging and spectroscopic data.<br/></p>

<p>Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. Let us slip beyond its boundary, the horizon, and tumble - on and on - down this crack in the universe. As we plunge, we'll see geometry fold, we'll feel the equations draw tight around us. Eventually, we'll pass it: the remains of a star, deep and dense and falling further far. And then - the bottom. Where time and space end, and the white hole is born . . .<br/><br/>With lightness and magic, here Rovelli traces the ongoing adventure of his own cutting-edge research, of the uncertainty and joy of going where we've not yet been. Guiding us to the edge of theory and experiment, he invites us to go beyond, to experience the fever and the disquiet of science. Here is the extraordinary life of a white hole.</p>

Big Bang theory is the prevailing theory of the origin of the universe and its development. Its main argument is so-called "galaxies escape". The analysis of the light from galaxies shows that the spectral lines are shifted to the red part of the spectrum. Based on the Doppler effect interpret this to mean that "most" of galaxies receding from the observer. They believe that back in time, galaxies were closer together. If we goes even further back in time, this means that the entire universe was compressed into a point that exploded. There we have Big Bang.<br/>By analysis of existing data, the author shows that the main argument for the Big Bang theory is incorrect.<br/><br/>Jan Slowak is born in Transylvania, Romania. He studied mathematics and computer science at the University Babes-Bolyai University in Cluj-Napoca, the capital of Transylvania. Jan is resident since 1988 in Sweden.

Statistical physics has its origins in attempts to describe the thermal properties of matter in terms of its constituent particles, and has played a fundamental role in the development of quantum mechanics. Based on lectures taught by Professor Kardar at MIT, this textbook introduces the central concepts and tools of statistical physics. It contains a chapter on probability and related issues such as the central limit theorem and information theory, and covers interacting particles, with an extensive description of the van der Waals equation and its derivation by mean field approximation. It also contains an integrated set of problems, with solutions to selected problems at the end of the book and a complete set of solutions is available to lecturers on a password protected website at www.cambridge.org/9780521873420. A companion volume, Statistical Physics of Fields, discusses non-mean field aspects of scaling and critical phenomena, through the perspective of renormalization group.
