Khan's Lectures: Handbook of the Physics of Radiation Therapy will provide a digest of the material contained in The Physics of Radiation Therapy. Lectures will be presented somewhat similar to a PowerPoint format, discussing key points of individual chapters. Selected diagrams from the textbook will be used to initiate the discussion. New illustrations will used, wherever needed, to enhance the understanding of important concepts. Discussion will be condensed and often bulleted. Theoretical details will be referred to the textbook and the cited literature. A problem set (practice questions) will be provided at the end of each chapter topic.

In this volume the physics involved in various astrophysical processes like the synthesis of light and heavier elements, explosive burning processes, core collapse supernova etc have been critically addressed with minimum mathematical derivations so as to suit all faculties of the readers. For graduate students there are solved problems with exercises at the end of each chapter, for researchers some recent works on the calculation of physical parameters of astrophysical importance like the calculation of Sfactors at low energies have been included, and for amateur readers there are lot of history, information and discussion on the astronuclear phenomenon. Please note: Taylor & Francis does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.

A free, world-class education for anyone, anywhere: this is the goal of the Khan Academy, a passion project that grew from an ex-engineer and hedge funder's online tutoring sessions with his niece, who was struggling with algebra, into a worldwide phenomenon. Today millions of students, parents, and teachers use the Khan Academy's free videos and software, which have expanded to encompass nearly every conceivable subject; and Academy techniques are being employed with exciting results in a growing number of classrooms around the globe. Like many innovators, Khan rethinks existing assumptions and imagines what education could be if freed from them. And his core idea-liberating teachers from lecturing and state-mandated calendars and opening up class time for truly human interaction-has become his life's passion. Schools seek his advice about connecting to students in a digital age, and people of all ages and backgrounds flock to the site to utilize this fresh approach to learning. In The One World Schoolhouse, Khan presents his radical vision for the future of education, as well as his own remarkable story, for the first time. In these pages, you will discover, among other things: How both students and teachers are being bound by a broken top-down model invented in Prussia two centuries ago Why technology will make classrooms more human and teachers more important How and why we can afford to pay educators the same as other professionals/DIV How we can bring creativity and true human interactivity back to learning/DIV Why we should be very optimistic about the future of learning. Parents and politicians routinely bemoan the state of our education system. Statistics suggest we've fallen behind the rest of the world in literacy, math, and sciences. With a shrewd reading of history, Khan explains how this crisis presented itself, and why a return to "mastery learning," abandoned in the twentieth century and ingeniously revived by tools like the Khan Academy, could offer the best opportunity to level the playing field, and to give all of our children a world-class education now. More than just a solution, The One World Schoolhouse serves as a call for free, universal, global education, and an explanation of how Khan's simple yet revolutionary thinking can help achieve this inspiring goal.

An overwhelmingly Arab-centric perspective dominates the West’s understanding of Islam and leads to a view of this religion as exclusively Middle Eastern and monolithic. Teena Purohit presses for a reorientation that would conceptualize Islam instead as a heterogeneous religion that has found a variety of expressions in local contexts throughout history. The story she tells of an Ismaili community in colonial India illustrates how much more complex Muslim identity is, and always has been, than the media would have us believe. The Aga Khan Case focuses on a nineteenth-century court case in Bombay that influenced how religious identity was defined in India and subsequently the British Empire. The case arose when a group of Indians known as the Khojas refused to pay tithes to the Aga Khan, a Persian nobleman and hereditary spiritual leader of the Ismailis. The Khojas abided by both Hindu and Muslim customs and did not identify with a single religion prior to the court’s ruling in 1866, when the judge declared them to be converts to Ismaili Islam beholden to the Aga Khan. In her analysis of the ginans, the religious texts of the Khojas that formed the basis of the judge’s decision, Purohit reveals that the religious practices they describe are not derivations of a Middle Eastern Islam but manifestations of a local vernacular one. Purohit suggests that only when we understand Islam as inseparable from the specific cultural milieus in which it flourishes do we fully grasp the meaning of this global religion.

How ornamentation enables a direct and immediate encounter between viewers and art objects Based on universal motifs, ornamentation occurs in many artistic traditions, though it reaches its most expressive, tangible, and unique form in the art of the Islamic world. The Mediation of Ornament shares a veteran art historian’s love for the sheer sensuality of Islamic ornamentation, but also uses this art to show how ornament serves as a consistent intermediary between viewers and artistic works from all cultures and periods. Oleg Grabar analyzes early and medieval Islamic objects, ranging from frontispieces in Yemen to tilework in the Alhambra, and compares them to Western examples, treating all pieces as testimony of the work, life, thought, and emotion experienced in one society. The Mediation of Ornament is essential reading for admirers of Islamic art and anyone interested in the ways of perceiving and understanding the arts more broadly.

This biography of the first foreign-born samurai and his journey from Africa to Japan is “a readable, compassionate account of an extraordinary life” (The Washington Post). When Yasuke arrived in Japan in the late 1500s, he had already traveled much of the known world. Kidnapped as a child, he had ended up a servant and bodyguard to the head of the Jesuits in Asia, with whom he traversed India and China learning multiple languages as he went. His arrival in Kyoto, however, literally caused a riot. Most Japanese people had never seen an African man before, and many of them saw him as the embodiment of the black-skinned Buddha. Among those who were drawn to his presence was Lord Nobunaga, head of the most powerful clan in Japan, who made Yasuke a samurai in his court. Soon, he was learning the traditions of Japan’s martial arts and ascending the upper echelons of Japanese society. In the four hundred years since, Yasuke has been known in Japan largely as a legendary, perhaps mythical figure. Now African Samurai presents the never-before-told biography of this unique figure of the sixteenth century, one whose travels between countries and cultures offers a new perspective on race in world history and a vivid portrait of life in medieval Japan. “Fast-paced, action-packed writing. . . . A new and important biography and an incredibly moving study of medieval Japan and solid perspective on its unification. Highly recommended.” —Library Journal (starred review) “Eminently readable. . . . a worthwhile and entertaining work.” —Publishers Weekly “A unique story of a unique man, and yet someone with whom we can all identify.” —Jack Weatherford, New York Times–bestselling author of Genghis Khan

Usman Khan was convicted of terrorism-related offences at age 20, and sent to high-security prison. He was released eight years later, and allowed to travel to London for one day, to attend an event marking the fifth anniversary of a prison education programme he participated in. On 29 November 2019, he sat with others at Fishmongers' Hall, some of whom he knew. Then he went to the bathroom to retrieve the things he had hidden there: a fake bomb vest and two knives, which he taped to his wrists. That day, he killed two people: Saskia Jones and Jack Merritt. Preti Taneja taught fiction writing in prison for three years. Merritt oversaw her program; Khan was one of her students. 'It is the immediate aftermath,' Taneja writes. 'I am living at the centre of a wound still fresh. The I is not only mine. It belongs to many.' In this searching lament Taneja interrogates the language of terror, trauma and grief; the fictions we believe and the voices we exclude. Contending with the pain of unspeakable loss set against public tragedy, she draws on history, memory, and powerful poetic predecessors to reckon with the systemic nature of atrocity. Blurring genre and form, Aftermath is a profound attempt to regain trust after violence and to recapture a politics of hope through a determined dream of abolition.
