A Volatile Picture: War and the Political Work of Photography in Sri Lanka (U Washington Press, 2026) by Dr. Vindhya Buthpitiya is a groundbreaking ethnography that explores how, in the context of Sri Lanka’s protracted civil war and its turbulent aftermath, photography has become bound to the Tamil political imagination. From state-commissioned images meant to surveil and rebel documentation of armed resistance, to the fragile memorials created from identity photographs of the disappeared, A Volatile Picture traces the making and moving of images across borders, communities, and generations. Studio portraits, passport pictures, family albums, atrocity photography, social media posts, and more act not only as records of loss and horror but also as vital tools for protest, solidarity, and the realization of alternate political futures. Drawing on transnational archival and ethnographic encounters and long-term fieldwork in northern Sri Lanka, Dr. Buthpitiya situates photography as both a volatile medium and a political practice. Photographs emerge here as incendiary agents—simultaneously evidencing and triggering violence, sustaining memory, and inciting new visions of liberation.This is the first in-depth study of Tamil photographic practices in Sri Lanka, offering a major contribution to the anthropology of war, visual culture, and South Asian studies. Richly researched and deeply humane, A Volatile Picture demonstrates how, amid devastation and displacement, photographs continue to generate truths, solidarities, and hopes that resist erasure.

In the thirteenth-century Mediterranean, commerce transformed as merchants shifted from Roman to Indo-Arabic numerals—an alternative that better facilitated complex calculations. It has long been known that this transition stemmed from Europe’s increasing exchanges with India, Persia, and the Arabic world. Yet much remains to be understood about how Indo-Arabic numerals—and the practical arithmetic they enabled—actually spread across Europe. As Dr. Raffaele Danna shows in The Craft of Indo-Arabic Numerals: How Practical Arithmetic Shaped Commerce and Mathematics in Western Europe, 1200–1600 (Harvard University Press, 2026), it was hundreds of ordinary merchants, schoolmasters, and artisans who nurtured these changes, thereby driving key advances in both commerce and mathematics.

Drawing on an original catalog of more than 1,200 practical arithmetic manuals, Dr. Danna charts the incremental spread of the new figures with unprecedented precision. While Italian merchants were the early adopters, it took nearly three centuries for Indo-Arabic numerals to become established in northern Europe. As Dr. Danna shows, adoption did not follow the routes of maritime trade. Rather, Indo-Arabic numerals moved gradually across the continent through inland networks of practitioners. Everywhere they went, the ten figures enhanced commercial practices and facilitated the emergence of a coherent language of mathematical craft. The growing social circulation of this knowledge, in turn, had a lasting impact on the economic trajectory of Western Europe. By the late sixteenth century, even academics were absorbing lessons from the vernacular tradition—a development that led to the first major breakthroughs in European mathematical theory since antiquity.

Combining economic history with the social history of mathematics, The Craft of Indo-Arabic Numerals illuminates the integral role of practical arithmetic in both intellectual and commercial transformations across Western Europe.

Stephen Sims’ New Atlantis essay examines how emerging technologies are reshaping the structure and authority of the modern nation-state. He argues that innovations such as artificial intelligence, drones, and networked warfare are weakening the traditional link between territorial control and the projection of power, enabling smaller actors to operate with unprecedented reach. At the same time, advanced states are enhancing their internal capabilities through data-driven governance and automation, increasing their ability to monitor and manage populations. This dynamic creates a paradox in which states grow more powerful domestically while becoming more vulnerable externally. Sims contends that sovereignty is fragmenting, with authority dispersing both to non-state actors and to transnational technological systems. The result is not the end of the nation-state, but its evolution into a more contested, uneven, and technologically mediated form.

When Disneyland opened to the public in 1955, it demystified the hidden world of factory automation through its extraordinary new attractions. In Disneyland and the Rise of Automation: How Technology Created the Happiest Place on Earth (Princeton University Press, 2026), Dr. Roland Betancourt tells the story of how the visionary engineers and designers at Disney transformed the technologies of the postwar assembly line into an entertainment experience unlike anything the world had ever seen.This book traces the origins and evolution of these technical innovations during the theme park’s first three decades in operation, exploring how engineers reimagined the systems and machines of industrial manufacturing and the military. The magnetic tape used to test ballistic missiles was repurposed to animate the talking macaws in the Enchanted Tiki Room. Programmable Logic Controllers, widely used on automotive assembly lines, brought to life the spectacular rides of the Matterhorn Bobsleds and Space Mountain. Dr. Betancourt shows how these and other attractions helped to allay fears about automation and job displacement in 1950s America. Along the way, he situates Disneyland’s remarkable creations within a broader history of the technologies that increasingly order and construct the world around us, from the Fordist factory to artificial intelligence.Essential reading for anyone interested in engineering, corporate histories, or popular culture, Disneyland and the Rise of Automation invites us to consider how technology and the logic of automation become integrated into our lives through entertainment.
