Books four and five of a landmark seven-volume work of medieval scientific study of optics.

Ibn al-Haytham was perhaps the greatest mathematician and physicist of the medieval Arabic/Islamic world. The most famous book in which he applied his scientific method is his Optics, through which he dealt with both the mathematics of rays of light and the physical aspects of the eye in seven comprehensive books. His rethinking of the entire science of optics set the scene for the whole of the subsequent development of the subject, influencing figures such as William of Ockham, Kepler, Descartes, and Christaan Huygens. The immense work of editing, translating into English, and commenting on this work was undertaken by Abdelhamid I. Sabra. This English translation of Books IV–V was completed by Sabra just before his death in 2013 with an introduction and critical analysis. It has been extensively revised by Jan Hogendijk.

A reflection on nation-building, identity, and the stories governments tell us about ourselves.

In 1949, English historian Herbert Butterfield published “Official History: Its Pitfalls and Its Criteria,” a now-famous diatribe against the practice of publishing official history. Butterfield was one of the earliest and strongest critics of what he saw as the British government’s attempts to control the past through the writing of history. But why was Butterfield so hostile to state-sanctioned history, and why do his views still matter today?
​
This important new book details how successive governments have applied a selective approach to the past in order to tell or retell Britain’s national history. Providing a unique overview of the main trends of official history in Britain since World War II, the book details how Butterfield came to suspect that the British government was trying to suppress vital documents revealing the Duke of Windsor’s dealings with Nazi Germany. This seemed to confirm his long-held belief that all governments would seek to manipulate history if they could and conceal the truth if they could not.

At the beginning of the twenty-first century, official history is still being written. The Control of the Past concludes with an insider’s perspective on the many issues it faces today—on freedom of information, social media, and reengaging with our nation’s colonial legacy. Governments have recently been given many reminders that history matters, and Butterfield’s work reminds us that we must remain vigilant in monitoring how they respond to the challenge.

A history of the development and importance of the office of poet laureate of Britain.

The office of the poet laureate of Britain was a highly prominent, relevant, and respectable institution throughout the long eighteenth century. First instituted for John Dryden in 1668, the laureateship developed from an honorific into a functionary office with a settled position in court, and in 1813 was bestowed upon Robert Southey, whose tenure transformed the office. Taking an interdisciplinary approach, this book examines the office’s institutional changes and public reception, the mechanics of each laureate’s appointment, and the works produced by the laureates before and after their appointments. It argues that the laureateship played a key part in some of the most vital trends in eighteenth-century culture.
 
At the core of the book is a new research paradigm that Leo Shipp calls the conceptual geography of culture. It shows that Britons routinely used spatial concepts to understand culture throughout the period, which became increasingly abstract over time. As part of this, Shipp shows, the court evolved from a concrete space in London to an abstract space capable of hosting the entire British public. The laureateship was a dynamic office positioned at the interface of court and public, evolving in line with its audiences. An important intervention in eighteenth-century historiography, this book presents a nuanced understanding of eighteenth-century culture and society, in which the laureateship exemplified the enduring centrality of the court to the British conceptual geography of culture.

The digital age throws questions of representation, participation, and humanitarianism back to the fore, as machine learning, algorithms, and big data centers take over the process of mapping the subjugated and subaltern. Mapping Crisis questions whether it is the map itself that is in crisis. This book brings together critical perspectives on the role that mapping people, knowledges, and data now plays in humanitarian work, both in cartographic terms and through data visualizations. Since the rise of Google Earth in 2005, there has been an explosion in the use of mapping tools to quantify and assess the needs of the poor, including those affected by climate change and the wider neo-liberal agenda. Yet, while there has been a huge upsurge in the data produced around these issues, the representation of people remains questionable. Some have argued that representation has diminished as people are increasingly reduced to data points. In turn, this data has become ever more difficult to analyze without vast computing power, leading to a dependency on the old colonial powers to refine the data of the poor, before selling it back to them.
