The concept of reciprocal space is over 100 years old, and has been of particular use by crystallographers in order to understand the patterns of spots when x-rays are diffracted by crystals. However, it has a much more general use, especially in the physics of the solid state. In order to understand what it is, how to construct it and how to make use of it, it is first necessary to start with the so-called real or direct space and then show how reciprocal space is related to it. Real space describes the objects we see around us, especially with regards to crystals, their physical shapes and symmetries and the arrangements of atoms within: the so-called crystal structure. Reciprocal space on the other hand deals with the crystals as seen through their diffraction images. Indeed, crystallographers are accustomed to working backwards from the diffraction images to the crystal structures, which we call crystal structure solution. In solid state physics, one usually works the other way, starting with reciprocal space to explain various solid-state properties, such as thermal and electrical phenomena. In this book, I start with the crystallographer's point of view of real and reciprocal space and then proceed to develop this in a form suitable for physics applications. Note that while for the crystallographer reciprocal space is a handy means of dealing with diffraction, for the solid-state physicist it is thought of as a way to describe the formation and motion of waves, in which case the physicist thinks of reciprocal space in terms of momentum or wave-vector k-space. This is because, for periodic structures, a characteristic of normal crystals, elementary quantum excitations, e.g. phonons and electrons, can be described both as particles and waves. The treatment given here, will be by necessity brief, but I would hope that this will suffice to lead the reader to build upon the concepts described. I have tried to write this book in a suitable form for both undergraduate and graduate students of what today we call "condensed matter physics."

The Mi’kmaq of eastern Canada were among the first indigenous North Americans to encounter colonial Europeans. As early as the mid-sixteenth century, they were trading with French fishers, and by the mid-seventeenth century, large numbers of Mi’kmaq had converted to Catholicism. Mi’kmaw Catholicism is perhaps best exemplified by the community’s regard for the figure of Saint Anne, the grandmother of Jesus. Every year for a week, coinciding with the saint’s feast day of July 26, Mi’kmaw peoples from communities throughout Quebec and eastern Canada gather on the small island of Potlotek, off the coast of Nova Scotia. It is, however, far from a conventional Catholic celebration. In fact, it expresses a complex relationship between the Mi’kmaq, Saint Anne, a series of eighteenth-century treaties, and a cultural hero named Kluskap. Finding Kluskap brings together years of historical research and learning among Mi’kmaw peoples on Cape Breton Island, Nova Scotia. The author’s long-term relationship with Mi’kmaw friends and colleagues provides a unique vantage point for scholarship, one shaped not only by personal relationships but also by the cultural, intellectual, and historical situations that inform postcolonial peoples. The picture that emerges when Saint Anne, Kluskap, and the mission are considered in concert with one another is one of the sacred life as a site of adjudication for both the meaning and efficacy of religion—and the impact of modern history on contemporary indigenous religion.

A moving memoir and an extraordinary love story that shows how an expert physician became a family caregiver and learned why care is so central to all our lives and yet is at risk in today's world. When Dr. Arthur Kleinman, an eminent Harvard psychiatrist and social anthropologist, began caring for his wife, Joan, after she was diagnosed with early-onset Alzheimer's disease, he found just how far the act of caregiving extended beyond the boundaries of medicine. In The Soul of Care: The Moral Education of a Husband and a Doctor, Kleinman delivers a deeply humane and inspiring story of his life in medicine and his marriage to Joan, and he describes the practical, emotional and moral aspects of caretaking. He also writes about the problems our society faces as medical technology advances and the cost of health care soars but caring for patients no longer seems important. Caregiving is long, hard, unglamorous work--at moments joyous, more often tedious, sometimes agonizing, but it is always rich in meaning. In the face of our current political indifference and the challenge to the health care system, he emphasizes how we must ask uncomfortable questions of ourselves, and of our doctors. To give care, to be "present" for someone who needs us, and to feel and show kindness are deep emotional and moral experiences, enactments of our core values. The practice of caregiving teaches us what is most important in life, and reveals the very heart of what it is to be human.

This collection of original essays offers a comprehensive examination of scientific progress, which has been a central topic in recent debates in philosophy of science. Traditionally, debates over scientific progress have focused on different methodological approaches, notably the epistemic and semantic approaches. The chapters in Part I of the book examine these two traditional approaches, as well as the newly revived functional and newly developed noetic approaches. Part II features in-depth case studies of scientific progress from the history of science. The chapters cover individual sciences including physics, chemistry, evolutionary biology, seismology, psychology, sociology, economics, and medicine. Finally, Part III of the book explores important issues from contemporary philosophy of science. These chapters address the implications of scientific progress for the scientific realism/anti-realism debate, incommensurability, values in science, idealisation, scientific speculation, interdisciplinarity, and scientific perspectivalism. New Philosophical Perspectives on Scientific Progress will be of interest to researchers and advanced students working on the history and philosophy of science.

The name of Raman is familiar to science not only through the effect that bears his name, but also due to derivative names such as stimulated Raman scattering and Raman laser. However, other than that he won the Nobel Prize, little is generally know about the man himself. But the story is fascinating. Raman fiercely cherished his independence and rejected government support for his research. A sharp critic of many government policies, he was often misunderstood and maligned, though his commitment to science and to its growth in India never wavered. Venkataraman's account deals with all these aspects of Raman's life and work, besides placing them in a proper perspective vis-a-vis the overall Indian scene. Numerous quotations help capture the mood and excitement of those times. The book is not only a lively biography of a colorful personality, but also required reading for anyone with a serious interest in and concern for Indian science.

Introduces the superstring theory that attempts to unite general relativity and quantum mechanics.

PULITZER PRIZE FINALIST • Benjamin Franklin, perhaps the pivotal figure in colonial and revolutionary America, comes vividly to life in this “thorough biography of ... America’s first Renaissance man” (The Washington Post) by the two-time Pulitzer Prize finalist, bestselling historian, and author of Our First Civil War. "The authoritative Franklin biography for our time.” —Joseph J. Ellis, author of the Pulitzer Prize-winning Founding Brothers Wit, diplomat, scientist, philosopher, businessman, inventor, and bon vivant, Benjamin Franklin's "life is one every American should know well, and it has not been told better than by Mr. Brands" (The Dallas Morning News). From penniless runaway to highly successful printer, from ardently loyal subject of Britain to architect of an alliance with France that ensured America’s independence, Franklin went from obscurity to become one of the world’s most admired figures, whose circle included the likes of Voltaire, Hume, Burke, and Kant. Drawing on previously unpublished letters and a host of other sources, acclaimed historian H. W. Brands has written a thoroughly engaging biography of the eighteenth-century genius. A much needed reminder of Franklin’s greatness and humanity, The First American is a work of meticulous scholarship that provides a magnificent tour of a legendary historical figure, a vital era in American life, and the countless arenas in which the protean Franklin left his legacy. Look for H.W. Brands's other biographies: ANDREW JACKSON, THE MAN WHO SAVED THE UNION (Ulysses S. Grant), TRAITOR TO HIS CLASS (Franklin Roosevelt) and REAGAN.

A little over ?ve years have passed since the ?rst edition of this book appeared in print. Seems like an instant but also eternity, especially considering numerous developments in the hardware and software that have made it from the laboratory test beds into the real world of powder diffraction. This prompted a revision, which had to be beyond cosmetic limits. The book was, and remains focused on standard laboratory powder diffractometry. It is still meant to be used as a text for teaching students about the capabilities and limitations of the powder diffraction method. We also hope that it goes beyond a simple text, and therefore, is useful as a reference to practitioners of the technique. The original book had seven long chapters that may have made its use as a text - convenient. So the second edition is broken down into 25 shorter chapters. The ?rst ?fteen are concerned with the fundamentals of powder diffraction, which makes it much more logical, considering a typical 16-week long semester. The last ten ch- ters are concerned with practical examples of structure solution and re?nement, which were preserved from the ?rst edition and expanded by another example – R solving the crystal structure of Tylenol .
