Image and Logic

A Material Culture of Microphysics

Peter Galison

University of Chicago Press, 1997

"I want to get at the blown glass of the early cloud chambers and the oozing noodles of wet nuclear emulsion; to the resounding crack of a high-voltage spark arcing across a high-tension chamber and leaving the lab stinking of ozone; to the silent, darkened room, with row after row of scanners sliding trackballs across projected bubble-chamber images. Pictures and pulses—I want to know where they came from, how pictures and counts got to be the bottom-line data of physics." (from the preface)

Image and Logic is the most detailed engagement to date with the impact of modern technology on what it means to "do" physics and to be a physicist. At the beginning of this century, physics was usually done by a lone researcher who put together experimental apparatus on a benchtop. Now experiments frequently are larger than a city block, and experimental physicists live very different lives: programming computers, working with industry, coordinating vast teams of scientists and engineers, and playing politics.

Peter L. Galison probes the material culture of experimental microphysics to reveal how the ever-increasing scale and complexity of apparatus have distanced physicists from the very science that drew them into experimenting, and have fragmented microphysics into different technical traditions much as apparatus have fragmented atoms to get at the fundamental building blocks of matter. At the same time, the necessity for teamwork in operating multimillion-dollar machines has created dynamic "trading zones," where instrument makers, theorists, and experimentalists meet, share knowledge, and coordinate the extraordinarily diverse pieces of the culture of modern microphysics: work, machines, evidence, and argument.

Instruments

Edited by Albert Van Helden and Thomas L. Hankins

University of Chicago Press, 1994

They measure, they demonstrate, they reveal unseen worlds. Through the ages, scientific instruments have been used not only to advance understanding, but also to advance careers, dazzle audiences, and impose standards. These eleven essays take stock of the philosophy of instrumentation and the impact of new instruments in both the physical and life sciences, carefully considering the important interplay between instruments and authority, audience, and culture.

Contributors include Albert Van Helden on telescopes and authority, Jan Golinski on the demonstrative order of proof in Lavoisier's chemistry, Bruce J. Hunt on the development of electrical standards, Deborah Warner on terrestrial magnetism, Bruce Hevly on Stanford's supervoltage X-ray tube, Robert W. Smith and Jose h N. Tatarewicz on devices and black boxes, Thatcher Deane on the imperial astronomical bureau in the Ming dynasty, Thomas L. Hankins on Louis-Bertrand Castel's ocular harpsichord, Simon Schaffer on demonstration devices in Georgian mechanics, Timothy Lenoir on Helmholtz and the materialities of communication, and Robert Frank on instruments, biological techniques, and the "all-or-none" principle.

Useful Optics

Walter T. Welford

University of Chicago Press, 1991

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.
