Engages with the impact of modern technology on experimental physicists. This study reveals how the increasing scale and complexity of apparatus has distanced physicists from the very science which drew them into experimenting, and has fragmented microphysics into different technical traditions.

This study of cognitive processes and scientific research begins with an autobiographical account of a research program that was designed to simulate scientific thinking. It explores such questions as: How do mental models, representations, expectations, and presumptions affect the creation of scientific knowledge? What is the effect of confirmation or disconfirmation on the process of experimentation and the direction of research? How does a scientist decide whether a model or theory is correct? The first-person narrative allows readers to follow the (...) research step by step and to work through the issues as the author grapples with them. The book also discusses important historical examples in which these issues have loomed large, among them the "great Devonian controversy," the etheric force controversy, and Kepler's theory of planetary motion. One fascinating chapter compares the cognitive styles of Bell and Edison and develops a cognitive framework that can be used to compare the creative processes of scientists and inventors. (shrink)

Hans Krebs' discovery, in 1932, of the urea cycle was a major event in biochemistry. This article describes a program, KEKADA, which models the heuristics Hans Krebs used in this discovery. KEKADA reacts to surprises, formulates explanations, and carries out experiments in the same manner as the evidence in the form of laboratory notebooks and interviews indicates Hans Krebs did. Furthermore, we answer a number of questions about the nature of the heuristics used by Krebs, in particular: How domain‐specific are (...) the heuristics? To what extent are they idiosyncratic to Krebs? To what extent do they represent general strategies of problem‐solving search?The relative generality of KEKADA allows us to view the control structure of KEKADA and its domain‐independent heuristics as a model of scientific experimentation that should apply over a broad domain.
