These sections together make an appropriate one-term advanced/graduate level course (mathematical prerequisites: vector analysis and simple partial-differential equations). The book is printed to make it easy for readers to identify these sections.• The remaining Track 2 material provides a wealth of advanced topics instructors can draw from to flesh out a two-term course, with Track 1 sections serving as prerequisites.

    QFT is the only physics theory that makes sense and that dispels or resolves the paradoxes of relativity and quantum mechanics that have confused and mystified so many people.

    These "Talks" offer a genuinely universal approach to Truth, by directly pointing to the certainty of our essential nature. By applying even a few of these passages to our life, we can become aware of the ever-present, abiding Reality.The great Indian sage Ramana Maharshi (1879-1950) had the unique gift of embodying the highest wisdom in the most ordinary manner. His words, full of insight and understanding, express the authentic experience of Enlightenment. For decades, they have guided people from diverse backgrounds and traditions to the Source of enduring peace and happiness.Through the wise words of this beloved sage, we are clearly and consistently shown how to reclaim our innate Freedom—simply by looking in the right place and discovering what has always been present. A fundamental shift of attention is all that is required. By approaching these dialogues in the spirit of inquiry, one has the opportunity to awaken to a greater Reality: that of our own Being, our true Self.

This is an ambitious work that truly ties the many different aspects of the subject together. It's rare to find something like this, especially considering the care and thoroughness that went into it.-- From the Foreword by George Noory, host of Coast to Coast AM.'As a follow-up to his previous books exploring the relationship between UFOs and the National Security State, historian Richard Dolan widens his perspective to explore all aspects of this provocative phenomenon. In this role, he takes us on a journey that brings to life the subtlety and depth of this rich subject, a truly captivating read.'--H. E. Puthoff, Ph.D., Director, Institute for Advanced Studies at AustinUFOs For the 21st Century Mind represents a new kind of book – one that clearly and intelligently addresses literally every aspect and implication of the most maligned, misunderstood and compelling subject in human history. Richard Dolan’s newest work is perfect reading for serious students of ufology as well as the absolute beginner. Inspired, particularly well written, and the product of a first class mind for this or any other century.--Peter Robbins, coauthor of the British bestseller, Left At East Gate: A First-Hand Account of the Rendlesham Forest UFO Incident, Its Cover-up and InvestigationThis is an invaluable treatment of the known facets and seemingly endless implications regarding UFOs, with a much-appreciated focus on the human experience. A job well done, Richard.-- Sam Maranto, Investigative Researcher

    But there is one other motive which is as strong as any of these — the search for beauty. Mathematics is an art, and as such affords the pleasures which all the arts afford." In this erudite, entertaining college-level text, Morris Kline, Professor Emeritus of Mathematics at New York University, provides the liberal arts student with a detailed treatment of mathematics in a cultural and historical context. The book can also act as a self-study vehicle for advanced high school students and laymen. Professor Kline begins with an overview, tracing the development of mathematics to the ancient Greeks, and following its evolution through the Middle Ages and the Renaissance to the present day. Subsequent chapters focus on specific subject areas, such as "Logic and Mathematics," "Number: The Fundamental Concept," "Parametric Equations and Curvilinear Motion," "The Differential Calculus," and "The Theory of Probability." Each of these sections offers a step-by-step explanation of concepts and then tests the student's understanding with exercises and problems. At the same time, these concepts are linked to pure and applied science, engineering, philosophy, the social sciences or even the arts.In one section, Professor Kline discusses non-Euclidean geometry, ranking it with evolution as one of the "two concepts which have most profoundly revolutionized our intellectual development since the nineteenth century." His lucid treatment of this difficult subject starts in the 1800s with the pioneering work of Gauss, Lobachevsky, Bolyai and Riemann, and moves forward to the theory of relativity, explaining the mathematical, scientific and philosophical aspects of this pivotal breakthrough. Mathematics for the Nonmathematician exemplifies Morris Kline's rare ability to simplify complex subjects for the nonspecialist.

    The book s two-part coverage organizes topics under basic theory, and assembles an arsenal of approximation schemes with illustrative applications. For physicists and engineers. "

    This theory describes how many seemingly desperate aspects of the world, from stock market crashes to mass extinctions, avalanches to solar flares, all share a set of simple, easily described properties."...a'must read'...Bak writes with such ease and lucidity, and his ideas are so intriguing...essential reading for those interested in complex systems...it will reward a sufficiently skeptical reader." -NATURE"...presents the theory (self-organized criticality) in a form easily absorbed by the non-mathematically inclined reader." -BOSTON BOOK REVIEW"I picture Bak as a kind of scientific musketeer; flamboyant, touchy, full of swagger and ready to join every fray... His book is written with panache. The style is brisk, the content stimulating. I recommend it as a bracing experience." -NEW SCIENTIST

    It is revealed how all unifications in physics have been based on incredibly simple ideas. Using a logical approach, it is explained how the great 20th century theories of relativity and quantum mechanics share a common base, and how they can be linked using an idea so simple that anyone can understand it. An idea which is so simple it has been hidden in plain sight.

    The book begins with relevant scientific fundamentals and progresses through an exploration of the solar system, stars, galaxies, and cosmology. The Astronomy textbook builds student understanding through the use of relevant analogies, clear and non-technical explanations, and rich illustrations. Mathematics is included in a flexible manner to meet the needs of individual instructors.

    Offering an approach with a visual/graphical emphasis, this text offers a number of examples on the premise that students learn best by doing. This book features an emphasis on interpretation of results and critical thinking over calculations.

    From the sudden expansion of a cloud of gas to the cooling of hot metal--everything is moved or restrained by four simple laws. Written by Peter Atkins, one of the world's leading authorities on thermodynamics, this powerful and compact introduction explains what these four laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader a step at a time, Atkins begins with Zeroth (so named because the first two laws were well established before scientists realized that a third law, relating to temperature, should precede them--hence the jocular name zeroth), and proceeds through the First, Second, and Third Laws, offering a clear account of concepts such as the availability of work and the conservation of energy. Atkins ranges from the fascinating theory of entropy (revealing how its unstoppable rise constitutes the engine of the universe), through the concept of free energy, and to the brink, and then beyond the brink, of absolute zero. About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.
