The Probabilistic Method by Noga Alon,Joel H. Spencer Pdf

Praise for the Third Edition “Researchers of any kind of extremal combinatorics or theoretical computer science will welcome the new edition of this book.” - MAA Reviews Maintaining a standard of excellence that establishes The Probabilistic Method as the leading reference on probabilistic methods in combinatorics, the Fourth Edition continues to feature a clear writing style, illustrative examples, and illuminating exercises. The new edition includes numerous updates to reflect the most recent developments and advances in discrete mathematics and the connections to other areas in mathematics, theoretical computer science, and statistical physics. Emphasizing the methodology and techniques that enable problem-solving, The Probabilistic Method, Fourth Edition begins with a description of tools applied to probabilistic arguments, including basic techniques that use expectation and variance as well as the more advanced applications of martingales and correlation inequalities. The authors explore where probabilistic techniques have been applied successfully and also examine topical coverage such as discrepancy and random graphs, circuit complexity, computational geometry, and derandomization of randomized algorithms. Written by two well-known authorities in the field, the Fourth Edition features: Additional exercises throughout with hints and solutions to select problems in an appendix to help readers obtain a deeper understanding of the best methods and techniques New coverage on topics such as the Local Lemma, Six Standard Deviations result in Discrepancy Theory, Property B, and graph limits Updated sections to reflect major developments on the newest topics, discussions of the hypergraph container method, and many new references and improved results The Probabilistic Method, Fourth Edition is an ideal textbook for upper-undergraduate and graduate-level students majoring in mathematics, computer science, operations research, and statistics. The Fourth Edition is also an excellent reference for researchers and combinatorists who use probabilistic methods, discrete mathematics, and number theory.

Philosophy of Physics by Tim Maudlin Pdf

Philosophical foundations of the physics of space-time This concise book introduces nonphysicists to the core philosophical issues surrounding the nature and structure of space and time, and is also an ideal resource for physicists interested in the conceptual foundations of space-time theory. Tim Maudlin's broad historical overview examines Aristotelian and Newtonian accounts of space and time, and traces how Galileo's conceptions of relativity and space-time led to Einstein's special and general theories of relativity. Maudlin explains special relativity with enough detail to solve concrete physical problems while presenting general relativity in more qualitative terms. Additional topics include the Twins Paradox, the physical aspects of the Lorentz-FitzGerald contraction, the constancy of the speed of light, time travel, the direction of time, and more. Introduces nonphysicists to the philosophical foundations of space-time theory Provides a broad historical overview, from Aristotle to Einstein Explains special relativity geometrically, emphasizing the intrinsic structure of space-time Covers the Twins Paradox, Galilean relativity, time travel, and more Requires only basic algebra and no formal knowledge of physics

Honor Among Enemies by David Weber Pdf

KNOW THY ENEMY For Captain Honor Harrington, it's sometimes hard to know who the enemy really is. Despite political foes, professional jealousies, and the scandal which drove her into exile, she's been offered a chance to reclaim her career as an officer of the Royal Manticoran Navy. But there's a catch. She must assume command of a "squadron" of jury-rigged armed merchantmen with crew drawn from the dregs of her service and somehow stop the pirates who have taken advantage of the Havenite War to plunder the Star Kingdom's commerce. That would be hard enough, but some of the "pirates" aren't exactly what they seem . . . and neither are some of her "friends," For Honor has been carefully chosen for her mission¾by two implacable and powerful enemies. The way they see it, either she stops the raiders or the raiders kill her . . . and either way, they win. At the publisher's request, this title is sold without DRM (Digital Rights Management).

Putnam and Beyond by Răzvan Gelca,Titu Andreescu Pdf

This book takes the reader on a journey through the world of college mathematics, focusing on some of the most important concepts and results in the theories of polynomials, linear algebra, real analysis, differential equations, coordinate geometry, trigonometry, elementary number theory, combinatorics, and probability. Preliminary material provides an overview of common methods of proof: argument by contradiction, mathematical induction, pigeonhole principle, ordered sets, and invariants. Each chapter systematically presents a single subject within which problems are clustered in each section according to the specific topic. The exposition is driven by nearly 1300 problems and examples chosen from numerous sources from around the world; many original contributions come from the authors. The source, author, and historical background are cited whenever possible. Complete solutions to all problems are given at the end of the book. This second edition includes new sections on quad ratic polynomials, curves in the plane, quadratic fields, combinatorics of numbers, and graph theory, and added problems or theoretical expansion of sections on polynomials, matrices, abstract algebra, limits of sequences and functions, derivatives and their applications, Stokes' theorem, analytical geometry, combinatorial geometry, and counting strategies. Using the W.L. Putnam Mathematical Competition for undergraduates as an inspiring symbol to build an appropriate math background for graduate studies in pure or applied mathematics, the reader is eased into transitioning from problem-solving at the high school level to the university and beyond, that is, to mathematical research. This work may be used as a study guide for the Putnam exam, as a text for many different problem-solving courses, and as a source of problems for standard courses in undergraduate mathematics. Putnam and Beyond is organized for independent study by undergraduate and gradu ate students, as well as teachers and researchers in the physical sciences who wish to expand their mathematical horizons.

Games by C. Thi Nguyen Pdf

"Games are a unique art form. The game designer doesn't just create a world; they create who you will be in that world. They tell you what abilities to use and what goals to take on. In other words, they specify a form of agency. Games work in the medium of agency. And to play them, we take on alternate agencies and submerge ourselves in them. What can we learn about our own rationality and agency, from thinking about games? We learn that we have a considerable degree of fluidity with our agency. First, we have the capacity for a peculiar sort of motivational inversion. For some of us, winning is not the point. We take on an interest in winning temporarily, so that we can play the game. Thus, we are capable of taking on temporary and disposable ends. We can submerge ourselves in alternate agencies, letting them dominate our consciousness, and then dropping them the moment the game is over. Games are, then, a way of recording forms of agency, of encoding them in artifacts. Our games are a library of agencies. And exploring that library can help us develop our own agency and autonomy. But this technology can also be used for art. Games can sculpt our practical activity, for the sake of the beauty of our own actions. Games are part of a crucial, but overlooked category of art - the process arts. These are the arts which evoke an activity, and then ask you to appreciate your own activity. And games are a special place where we can foster beautiful experiences of our own activity. Because our struggles, in games, can be designed to fit our capacities. Games can present a harmonious world, where our abilities fit the task, and where we pursue obvious goals and act under clear values. Games are a kind of existential balm against the difficult and exhausting value clarity of the world. But this presents a special danger. Games can be a fantasy of value clarity. And when that fantasy leaks out into the world, we can be tempted to oversimplify our enduring values. Then, the pleasures of games can seduce us away from our autonomy, and reduce our agency."--
