Explains that although ethical aspects of science are rarely discussed, they are of interest to the public. Identifies Americans' concerns about science-related issues and how religion influences the issues. (Contains 21 references.) (Author/YDS)

Traces electronegativity in four fundamental areas of chemistry during the period 1870-1910: (1) the relationship between electronegativity and classical valence; (2) the relationship between electronegativity and periodic law; (3) the relationship between electronegativity thermochemistry; and (4) the relationship between electronegativity and…

Argues that the texts that are the chief vehicles through which scientific knowledge is created and disseminated must be systematically examined. Argues that scientific knowledge is not special but is social, the result not of revelation but of persuasion. Concludes that rhetorical analysis is appropriate to the task. (RS)

The most important changes that have taken place in behaviorism since John B. Watson's 1913 article are the introduction of the intervening variable approach and the understanding that psychology is both an experimental and a psychometric science. The only observables available to psychology are stimuli and response. (SLD)

Argues that history and philosophy of science can investigate scientific questions that are excluded from science itself by working as a shadow discipline, complementing the specialist science in the production of knowledge about nature. Contains 16 references. (Author/WRM)

Part of a larger work on the history, philosophy, and utilization of pendulum motion studies, addresses the fate of Christiaan Huygens' 1673 proposal to use the length of a seconds pendulum as a universal, natural, and objective standard of length. (SAH)

Explores the problem of dominance as a concept, traces its persistence to the history of mythic images of Mendel, and discusses how we can mend the flaws while providing valuable lessons in the history and nature of science. (SAH)

Tells the story of an experiment conducted by Galileo and proves that a light pebble and a heavy rock travel with equal speed when dropped from the same distance and touch the ground at the same time. Indicates the importance of open-mindedness and tolerance. First published in 1939. (YDS)

Attempts to ascertain whether the presence of biasing values in the practice of science is an inbuilt feature of an idealized institution, Science, and judges that those values inbuilt to Science are not a source of bias. (Author/MM)
