"What is time? This question has fascinated philosophers, mathematicians, and scientists for thousands of years. Why does time seem to speed up with age? What is its connection with memory, anticipation, and sleep cycles? Award-winning author and mathematician Joseph Mazur provides an engaging exploration of how the understanding of time has evolved throughout human history and offers a compelling new vision, submitting that time lives within us. Our cells, he notes, have a temporal awareness, guided by environmental cues in sync with patterns of social interaction. Readers learn that, as a consequence of time's personal nature, a forty-eight-hour journey on the Space Shuttle can feel shorter than a six-hour trip on the Soyuz capsule, that the Amondawa of the Amazon do not have ages, and that time speeds up with fever and slows down when we feel in danger. With a narrative punctuated by personal stories of time's effects on truck drivers, Olympic racers, prisoners, and clockmakers, Mazur's journey is filled with fascinating insights into how our technologies, our bodies, and our attitudes can change our perceptions. Ultimately, time reveals itself as something that rides on the rhythms of our minds. 'The Clock Mirage' presents an innovative perspective that will force us to rethink our relationship with time, and how best to use it"--Jacket.

This ambitious book is about a way of building that for centuries dominated the making of monumental architecture – yet now not only is it lost as practice, but knowledge of its very existence is consigned to oblivion. In pre-modern Europe, the architect built not just with imagination, brick and mortar, but with time, using vast quantities of duration to erect monumental buildings that otherwise would have been impossible. Not mere medieval muddling-through, this entailed a sophisticated set of norms and practices. Virtually all the great cathedrals of France and the rest of Europe were built under this regime, here given the name ‘Building-in-Time’. In particular, the major works of pre-modern Italy, from the Pisa cathedral group to the cathedrals of Milan,Venice and Siena, and from the monuments of fourteenth-century Florence to the new St Peter’s – the apotheosis of the practice – are thus cast in an entirely new light. Even as ‘Building-in-Time’ was flourishing, the fifteenth-century Italian architect Leon Battista Alberti proposed a new temporal regime whereby time would ideally be excluded from the making of architecture (‘Building-outside-Time’). Planning and building, which had formed one fluid, imbricated process, were to be sharply divided, and the change that always came with time excluded from architectural facture. Ironically, it was Brunelleschi, as creator of the cupola of Florence cathedral and one of the supreme practitioners of Building-in-Time, who was the lynchpin of Alberti’s turn to the arts in the mid-1430s. That he arrived in Florence just at the moment Brunelleschi’s dome was being completed was crucial to Alberti’s subsequent career in visual culture. Yet his relationship to Brunelleschi was conflicted; first praising and attaching himself to Brunelleschi, later Alberti silently sought to banish him from history’s central stage. In telling this story, Marvin Trachtenberg rewrites the history of medieval and Renaissance architecture in Italy and recasts the turn to modernity in new terms, those of temporality and its role in architectural theory and practice. Recovering this lost element of the deep architectural past allows us also to see the present in a new way: that temporality is not any neutral or secondary factor in modern architecture culture, but an epistemic condition that silently affects all production and experience of the built environment.

Up until the end of the eighteenth century, the way Ottomans used their clocks conformed to the inner logic of their own temporal culture. However, this began to change rather dramatically during the nineteenth century, as the Ottoman Empire was increasingly assimilated into the European-dominated global economy and the project of modern state building began to gather momentum. In Reading Clocks, Alla Turca , Avner Wishnitzer unravels the complexity of Ottoman temporal culture and for the first time tells the story of its transformation. He explains that in their attempt to attain better surveillance capabilities and higher levels of regularity and efficiency, various organs of the reforming Ottoman state developed elaborate temporal constructs in which clocks played an increasingly important role. As the reform movement spread beyond the government apparatus, emerging groups of officers, bureaucrats, and urban professionals incorporated novel time-related ideas, values, and behaviors into their self-consciously “modern” outlook and lifestyle. Acculturated in the highly regimented environment of schools and barracks, they came to identify efficiency and temporal regularity with progress and the former temporal patterns with the old political order. Drawing on a wealth of archival and literary sources, Wishnitzer’s original and highly important work presents the shifting culture of time as an arena in which Ottoman social groups competed for legitimacy and a medium through which the very concept of modernity was defined. Reading Clocks, Alla Turca breaks new ground in the study of the Middle East and presents us with a new understanding of the relationship between time and modernity.
