In Baroque Science, Ofer Gal and Raz Chen-Morris present a radically new perspective on the scientific revolution of the seventeenth century. Instead of celebrating the triumph of reason and rationality, they study the paradoxes and anxieties that stemmed from the New Science and the intellectual compromises that shaped it and enabled its spectacular success.
 
Gal and Chen-Morris show how the protagonists of the new mathematical natural philosophy grasped at the very far and very small by entrusting observation to the mediation of artificial instruments, and how they justified this mediation by naturalizing and denigrating the human senses. They show how the physical-mathematical ordering of heavens and earth demanded obscure and spurious mathematical procedures, replacing the divine harmonies of the late Renaissance with an assemblage of isolated, contingent laws and approximated constants.  Finally, they show how the new savants, forced to contend that reason is hopelessly estranged from its surrounding world and that nature is irreducibly complex, turned to the passions to provide an alternative, naturalized foundation for their epistemology and ethics.
 
Enforcing order in the face of threatening chaos, blurring the boundaries of the natural and the artificial, and mobilizing the passions in the service of objective knowledge, the New Science, Gal and Chen-Morris reveal, is a Baroque phenomenon: deeply entrenched in and crucially formative of the culture of its time.

From its inception in Greek antiquity, the science of optics was aimed primarily at explaining sight and accounting for why things look as they do. By the end of the seventeenth century, however, the analytic focus of optics had shifted to light: its fundamental properties and such physical behaviors as reflection, refraction, and diffraction. This dramatic shift—which A. Mark Smith characterizes as the “Keplerian turn”—lies at the heart of this fascinating and pioneering study.       
           
Breaking from previous scholarship that sees Johannes Kepler as the culmination of a long-evolving optical tradition that traced back to Greek antiquity via the Muslim Middle Ages, Smith presents Kepler instead as marking a rupture with this tradition, arguing that his theory of retinal imaging, which was published in 1604, was instrumental in prompting the turn from sight to light. Kepler’s new theory of sight, Smith reveals, thus takes on true historical significance: by treating the eye as a mere light-focusing device rather than an image-producing instrument—as traditionally understood—Kepler’s account of retinal imaging helped spur the shift in analytic focus that eventually led to modern optics. 
           
A sweeping survey, From Sight to Light is poised to become the standard reference for historians of optics as well as those interested more broadly in the history of science, the history of art, and cultural and intellectual history.

Today few would think of astronomy and astrology as fields related to theology. Fewer still would know that physically absorbing planetary rays was once considered to have medical and psychological effects. But this was the understanding of light radiation held by certain natural philosophers of early modern Europe, and that, argues Mary Quinlan-McGrath, was why educated people of the Renaissance commissioned artworks centered on astrological themes and practices.

 

Influences is the first book to reveal how important Renaissance artworks were designed to be not only beautiful but also—perhaps even primarily—functional. From the fresco cycles at Caprarola, to the Vatican’s Sala dei Pontefici, to the Villa Farnesina, these great works were commissioned to selectively capture and then transmit celestial radiation, influencing the bodies and minds of their audiences. Quinlan-McGrath examines the sophisticated logic behind these theories and practices and, along the way, sheds light on early creation theory; the relationship between astrology and natural theology; and the protochemistry, physics, and mathematics of rays.

 

An original and intellectually stimulating study, Influences adds a new dimension to the understanding of aesthetics among Renaissance patrons and a new meaning to the seductive powers of art.  

How perceptual technologies have shaped the history of war from the Renaissance to the present

From ubiquitous surveillance to drone strikes that put “warheads onto foreheads,” we live in a world of globalized, individualized targeting. The perils are great. In The Eye of War, Antoine Bousquet provides both a sweeping historical overview of military perception technologies and a disquieting lens on a world that is, increasingly, one in which anything or anyone that can be perceived can be destroyed—in which to see is to destroy. 

Arguing that modern-day global targeting is dissolving the conventionally bounded spaces of armed conflict, Bousquet shows that over several centuries, a logistical order of militarized perception has come into ascendancy, bringing perception and annihilation into ever-closer alignment. The efforts deployed to evade this deadly visibility have correspondingly intensified, yielding practices of radical concealment that presage a wholesale disappearance of the customary space of the battlefield. Beginning with the Renaissance’s fateful discovery of linear perspective, The Eye of War discloses the entanglement of the sciences and techniques of perception, representation, and localization in the modern era amid the perpetual quest for military superiority. In a survey that ranges from the telescope, aerial photograph, and gridded map to radar, digital imaging, and the geographic information system, Bousquet shows how successive technological systems have profoundly shaped the history of warfare and the experience of soldiering. 

A work of grand historical sweep and remarkable analytical power, The Eye of War explores the implications of militarized perception for the character of war in the twenty-first century and the place of human subjects within its increasingly technical armature.

Galileo never set foot on the Iberian Peninsula, yet, as Enrique García Santo-Tomás unfolds in The Refracted Muse, the news of his work with telescopes brought him to surprising prominence—not just among Spaniards working in the developing science of optometry but among creative writers as well.
 
While Spain is often thought to have taken little notice of the Scientific Revolution, García Santo-Tomás tells a different story, one that reveals Golden Age Spanish literature to be in close dialogue with the New Science. Drawing on the work of writers such as Cervantes, Lope de Vega, Calderón de la Barca, and Quevedo, he helps us trace the influence of science and discovery on the rapidly developing and highly playful genre of the novel. Indeed, García Santo-Tomás makes a strong case that the rise of the novel cannot be fully understood without taking into account its relationship to the scientific discoveries of the period.

Kepler's successful solution to the problem of vision early in the seventeenth century was a theoretical triumph as significant as many of the more celebrated developments of the scientific revolution. Yet the full import of Kepler's arguments can be grasped only when they are viewed against the background of ancient, medieval, and Renaissance visual theory. David C. Lindberg provides this background, and in doing so he fills the gap in historical scholarship and constructs a model for tracing the development of scientific ideas.

David C. Lindberg is professor and chairman of the department of the history of science at the University of Wisconsin, Madison.

Students and professionals alike have long felt the need of a modern source of practical advice on the use of optical tools in scientific research. Walter T. Welford's Useful Optics meets this need.

Welford offers a succinct review of principles basic to the construction and use of optics in physics. His lucid explanations and clear illustrations will particularly help those whose interests lie in other areas but who nevertheless must understand enough about optics to create the experimental apparatus necessary to their research. Consistently emphasizing applications and practical points of design, Welford covers a host of topics: mirrors and prisms, optical materials, aberration, the limits of image formation and resolution, illumination for image-forming systems, laser beams, interference and interferometry, detectors and light sources, holography, and more. The final chapter deals with putting together an experimental optics system.

Many areas of the physical sciences and engineering increasingly demand an appreciation of optics. Welford's Useful Optics will prove indispensable to any researcher trying to develop and use effective optical apparatus.

Walter T. Welford (1916-1990) was professor of physics at Imperial College of Science, Technology and Medicine from 1951 until his death. He was a Fellow of the Royal Society and of the Optical Society of America.
