American Surfaces, Stephen Shore's largely unpublished series of photographs from 1972-3, took documentary photography to a new level. When first exhibited at the Light Gallery in New York this visual diary of Shore's travels across the United States confounded critics. Displayed as hundreds and hundreds of colour photographs, processed simply at Kodak's labs in New Jersey, they were a stark contrast to the formal, black-and-white prints that were recognized as art photography at the time. Despite its unfavourable reviews, the show was bought in its entirety by Weston Naef, then Curator of Photography at the Metropolitan Museum in New York, where 220 of the photographs now reside. American Surfaces has since become the benchmark for documenting our fast-living, consumer-orientated world, a body of work that followed on from Walker Evans and Robert Frank's experiences of crossing the United States and which continues to influence photographers today. This book brings together the largest selection of images yet published from the series and is the first time they have been sequenced in the order in which they were taken. American Surfaces follows Shore's extraordinary journey, travelling first into the deep South before taking Route 66 from Flagstaff to Chicago, and returning home to New York to continue his visual diary in his home city.

The book was easy to understand, with many examples. The exercises were well chosen, and served to give further examples and developments of the theory. --William Goldman, University of Maryland In this book, Miranda takes the approach that algebraic curves are best encountered for the first time over the complex numbers, where the reader's classical intuition about surfaces, integration, and other concepts can be brought into play. Therefore, many examples of algebraic curves are presented in the first chapters. In this way, the book begins as a primer on Riemann surfaces, with complex charts and meromorphic functions taking center stage. But the main examples come from projective curves, and slowly but surely the text moves toward the algebraic category. Proofs of the Riemann-Roch and Serre Duality Theorems are presented in an algebraic manner, via an adaptation of the adelic proof, expressed completely in terms of solving a Mittag-Leffler problem. Sheaves and cohomology are introduced as a unifying device in the latter chapters, so that their utility and naturalness are immediately obvious. Requiring a background of one semester of complex variable theory and a year of abstract algebra, this is an excellent graduate textbook for a second-semester course in complex variables or a year-long course in algebraic geometry.

Our first knowledge of differential geometry usually comes from the study of the curves and surfaces in I\!\!R^3 that arise in calculus. Here we learn about line and surface integrals, divergence and curl, and the various forms of Stokes' Theorem. If we are fortunate, we may encounter curvature and such things as the Serret-Frenet formulas. With just the basic tools from multivariable calculus, plus a little knowledge of linear algebra, it is possible to begin a much richer and rewarding study of differential geometry, which is what is presented in this book. It starts with an introduction to the classical differential geometry of curves and surfaces in Euclidean space, then leads to an introduction to the Riemannian geometry of more general manifolds, including a look at Einstein spaces. An important bridge from the low-dimensional theory to the general case is provided by a chapter on the intrinsic geometry of surfaces. The first half of the book, covering the geometry of curves and surfaces, would be suitable for a one-semester undergraduate course. The local and global theories of curves and surfaces are presented, including detailed discussions of surfaces of rotation, ruled surfaces, and minimal surfaces. The second half of the book, which could be used for a more advanced course, begins with an introduction to differentiable manifolds, Riemannian structures, and the curvature tensor. Two special topics are treated in detail: spaces of constant curvature and Einstein spaces. The main goal of the book is to get started in a fairly elementary way, then to guide the reader toward more sophisticated concepts and more advanced topics. There are many examples and exercises to help along the way. Numerous figures help the reader visualize key concepts and examples, especially in lower dimensions. For the second edition, a number of errors were corrected and some text and a number of figures have been added.

Minimal surfaces date back to Euler and Lagrange and the beginning of the calculus of variations. Many of the techniques developed have played key roles in geometry and partial differential equations. Examples include monotonicity and tangent cone analysis originating in the regularity theory for minimal surfaces, estimates for nonlinear equations based on the maximum principle arising in Bernstein's classical work, and even Lebesgue's definition of the integral that he developed in his thesis on the Plateau problem for minimal surfaces. This book starts with the classical theory of minimal surfaces and ends up with current research topics. Of the various ways of approaching minimal surfaces (from complex analysis, PDE, or geometric measure theory), the authors have chosen to focus on the PDE aspects of the theory. The book also contains some of the applications of minimal surfaces to other fields including low dimensional topology, general relativity, and materials science. The only prerequisites needed for this book are a basic knowledge of Riemannian geometry and some familiarity with the maximum principle.

In most mathematics textbooks, the most exciting part of mathematics - the process of invention and discovery - is completely hidden from the student. The aim of Knots and Surfaces is to change all that. Knots and Surfaces guides the reader through Euler's formula, one and two-sided surfaces, and knot theory using games and examples. By means of a series of carefully selected tasks, this book leads the reader on to discover some real mathematics. There are no formulas to memorize; no procedures to follow. This book is a guide to the mathematics - it starts you in the right direction and brings you back if you stray too far. Discovery is left to you. This book is aimed at undergraduates and those with little background knowledge of mathematics.

In February 1968 the Beatles went to India for an extended stay with their new guru, Maharishi Mahesh Yogi. It may have been the most momentous spiritual retreat since Jesus spent those forty days in the wilderness. With these words, Philip Goldberg begins his monumental work, American Veda, a fascinating look at India’s remarkable impact on Western culture. This eye-opening popular history shows how the ancient philosophy of Vedanta and the mind-body methods of Yoga have profoundly affected the worldview of millions of Americans and radically altered the religious landscape. What exploded in the 1960s actually began more than two hundred years earlier, when the United States started importing knowledge as well as tangy spices and colorful fabrics from Asia. The first translations of Hindu texts found their way into the libraries of John Adams and Ralph Waldo Emerson. From there the ideas spread to Henry David Thoreau, Walt Whitman, and succeeding generations of receptive Americans, who absorbed India’s “science of consciousness” and wove it into the fabric of their lives. Charismatic teachers like Swami Vivekananda and Paramahansa Yogananda came west in waves, prompting leading intellectuals, artists, and scientists such as Aldous Huxley, Joseph Campbell, Allen Ginsberg, J. D. Salinger, John Coltrane, Dean Ornish, and Richard Alpert, aka Ram Dass, to adapt and disseminate what they learned from them. The impact has been enormous, enlarging our current understanding of the mind and body and dramatically changing how we view ourselves and our place in the cosmos. Goldberg paints a compelling picture of this remarkable East-to-West transmission, showing how it accelerated through the decades and eventually moved from the counterculture into our laboratories, libraries, and living rooms. Now physicians and therapists routinely recommend meditation, words like karma and mantra are part of our everyday vocabulary, and Yoga studios are as ubiquitous as Starbuckses. The insights of India’s sages permeate so much of what we think, believe, and do that they have redefined the meaning of life for millions of Americans—and continue to do so every day. Rich in detail and expansive in scope, American Veda shows how we have come to accept and live by the central teaching of Vedic wisdom: “Truth is one, the wise call it by many names.”
