2003 Paul Bunge Prize of the Hans R. Jenemann Foundation for the History of Scientific InstrumentsJudging the brightness and color of light has long been contentious. Alternately described as impossible and routine, it was beset by problems both technical and social. How trustworthy could such measurements be? Was the best standard of intensity a gas lamp, an incandescent bulb, or a glowing pool of molten metal? And how much did the answers depend on the background of the specialist?A History of Light and Colour Measurement: Science in the Shadows is a history of the hidden workings of physical science-a technical endeavor embedded in a social context. It argues that this "undisciplined" subject, straddling academia, commerce, and regulation, may be typical not only of 20th century science, but of its future.Attracting scientists, engineers, industrialists, and artists, the developing subject produced a new breed of practitioners having mixed provenance. The new measurers of light had to decide the shape not only of their specialism but of their careers: were they to be a part of physics, engineering, or psychology? The physical scientists who dominated the subject into the early 20th century made their central aim the replacement of the problematic human eye with physical detectors of light. For psychologists between the wars, though, describing the complexity of color was more important than quantifying a handful of its dimensions. And after WWII, military designers shaped the subject of radiometry and subsumed photometry and colorimetry within it. Never attaining a professional cachet, these various specialists moved fluidly between science and technology; through government, industry, and administration.

Weaving together intellectual history, philosophy, and social studies, Sean Johnston offers a unique appraisal of the history of science and the nature of this evolving discipline. Science is all-encompassing and new developments are usually mired in controversy; nevertheless, it is a driving force of the modern world. Based on its past, where might it lead us in the twenty-first century?

This is the story of a seductive idea. Over the past century, the potential of new technology to solve social dilemmas has captivated modern culture. From apps that encourage physical activity to airport scanners meant to prevent terrorism, the concept that clever innovation can improve society is irresistible, but faith in such technological fixes is seldom questioned. Where did this idea come from, what makes it so appealing, and how does it endanger our future? Techno-Fixers traces the source of modern confidence in technology to engineering hubris, radical utopian movements, science fiction fanzines, policy-makers' soundbites, corporate marketing, and optimistic consumer culture from the turn of the twentieth century until today. Sean Johnston demonstrates that, through the promotion of prominent government scientists, technocrats, entrepreneurs, and popular media, modern invention became the favourite tool for addressing human problems and society's ills. Nonetheless, when it comes to assessing the success of cigarette filters as the solution to safe smoking, or DDT as the answer for agricultural productivity, the evidence is sobering. Cautioning that the rhetoric of technological fixes seldom matches reality, Johnston examines how employing innovation to bypass traditional methods can foster as many problems as it solves. A critical examination of modern faith in technology, Techno-Fixers evaluates past mistakes, present implications, and future opportunities for innovating societies.
