Consolations of Philosophy Penguin

Alain de Botton, best-selling author of How Proust can Change Your Life, has set six of the finest minds in the history of philosophy to work on the problems of everyday life. Here then are Socrates, Epicurus, Seneca, Montaigne, Schopenhauer and Nietzsche on some of the things that bother us all; lack of money, the pain of love, inadequacy, anxiety, the fear of failure and the pressure to conform.

The goal of this book is to expose the reader to the indispensable role that mathematics---often very abstract---plays in modern physics. Starting with the notion of vector spaces, the first half of the book develops topics as diverse as algebras, classical orthogonal polynomials, Fourier analysis, complex analysis, differential and integral equations, operator theory, and multi-dimensional Green's functions. The second half of the book introduces groups, manifolds, Lie groups and their representations, Clifford algebras and their representations, and fiber bundles and their applications to differential geometry and gauge theories.§This second edition is a substantial revision of the first one with a complete rewriting of many chapters and the addition of new ones, including chapters on algebras, representation of Clifford algebras and spinors, fiber bundles, and gauge theories. The spirit of the first edition, namely the balance between rigor and physical application, has been maintained, as is the abundance of historical notes and worked out examples that demonstrate the "unreasonable effectiveness of mathematics" in modern physics.§Einstein has famously said, "The most incomprehensible thing about nature is that it is comprehensible." What he had in mind was reiterated in another one of his famous quotes concerning the question of how " ... mathematics, being after all a product of human thought, is so admirably appropriate to the objects of reality." It is a question that comes to everyone's mind when encountering the highly abstract mathematics required for a deep understanding of modern physics. It is the experience that Eugene Wigner so profoundly described as "the unreasonable effectiveness of mathematics in the natural sciences."§Some praise for the previous edition:§PAGEOPH [Pure and Applied Geophysics]§Review by Daniel Wojcik, University of Maryland§"This volume should be a welcome addition to any collection. The book is well written and explanations are usually clear. Lives of famous mathematicians and physicists are scattered within the book. They are quite extended, often amusing, making nice interludes. Numerous exercises help the student practice the methods introduced. I have recently been using this book for an extended time and acquired a liking for it. Among all the available books treating mathematical methods of physics this one certainly stands out and assuredly it would suit the needs of many physics readers."§ZENTRALBLATT MATH§Review by G.Roepstorff, University of Aachen, Germany§" Unlike most existing texts with the same emphasis and audience, which are merely collections of facts and formulas, the present book is more systematic, self-contained, with a level of presentation that tends to be more formal and abstract. This entails proving a large number of theorems, lemmas, and corollaries, deferring most of the applications that physics students might be interested in to the example sections in small print. Indeed, there are 350 worked-out examples and about 850 problems. A very nice feature is the way the author intertwines the formalism with the life stories and anecdotes of some mathematicians and physicists, leading at their times. As is often the case, the historical view point helps to understand and appreciate the ideas presented in the text. For the physics student in the middle of his training, it will certainly prove to be extremely useful." §THE PHYSICIST §Review by Paul Davies, Orion Productions, Adelaide, Australia§"I am pleased to have so many topics collected in a single volume. All the tricks are there of course, but supported by sufficient rigour and substantiation to make the dedicated mathematical physicist sigh with delight."§EMS [EUROPEAN MATHEMATICAL SOCIETY] NEWSLETTER§"This book is a condensed exposition of the mathematics that is met in most parts of physics. The presentation attains a very good balance between the formal introduction of concepts, theorems and pr

Yoga Classical Hatha Yoga: 84 Classical Asanas and Their Variations Design Marque
Książki / Literatura obcojęzyczna
Asana: The Third Limb of Asht (eight) anga (limbs) Yoga Asana in modern yoga has become a synonym for Yoga. Most yoga followers are practising kriyas in the form of Suriya-namaskar or vinyasa and asana as a physical workout for many benefits like keeping fit, gaining flexibility, feeling good, being strong, looking attractive and enhancing vital energy. There is nothing wrong in that as we all need a healthy and strong body to begin. Swami Vivekananda states that, "all our immoral behaviour problems are rooted in weakness." To be free or to walk on a path to freedom and joy, we need to be very strong and healthy. In Shiva Samhita, Hatha Yoga Pradipika, Gheranda Samhita and other scriptures there is mention of 8,400,000 Asanas, which means form of births or life, YONI. We all have to go through each and every life form to learn and experience to grow. Out of those they say only 84 are important. Out of those 84 only 32 are most important and out of those, 4 sitting postures are essential ones. To be successful in pranayama and meditation one needs to master one of them. This book attempts to describe these 84 important postures as they were taught to me (Yogachariya Jnandev / Surender Saini). According to Patanjali there are three steps to Asana. First is taking the position. The second is being aware to your position and the third is letting go of effort and relaxing to be comfortable. He describes Asana as 'sthiram sukham asanam 2.46' this means a 'STEADY, COMFORTABLE BODY POSTURE'. According to Patanjali and Hatha Yoga traditions practice of Asana and kriya should be slow, steady, and effortless with full awareness or attention. Our breath and mind should be merged with our practice. There should not be vigorous force, jerks and strains in your Hatha Yoga practice. This is the authentic was in which Yoga was taught and is still taught in older traditions.
