An essay review of A. Megill, ed., Rethinking objectivity (1994); J. Appleby, L. Hunt, and M. Jacob, Telling the truth about history (1994); S. Shapin, A social history of truth (1994);T. Porter, Trust in numbers (1995). It makes the point that as challenges to belief in truth and in objectivity have escaped from academic discussion, becoming axioms of popular culture, many scholars who previously contributed to undermining that belief are becoming alarmed at the consequences of wholesale voluntarism.

A critical examination of the concepts and assumptions regarding radiation fields and their interaction with matter underlying the invention of the ammonia beam maser by Charles Townes and his collaborators at Columbia University in the early 1950s, emphasizing particularly that the merits of the device as ‘atomic clock’ were not anticipated, and that until it actually worked the maser was not a priority project in Townes laboratory.
An overview of the exhibition in the Smithsonian Institution Libraries’ Dibner Gallery in the Museum, August 1993 to May 1994. The last exhibition to be curated by Ellen Wells, it traced the history of tunneling technology, from antiquity to the present, with particular emphasis on the 19th century.
Consideration of the signal/noise ratio became widespread, indeed mandatory, in physical research only in the years following World War II, largely as a result of analyses and techniques developed to detect a ‘real’ signal in the noisy output of a radar receiver. "Lock-in detection,” most influentially embodied in R. H. Dicke’s microwave radiometer, 1943, is a procedure for noise reduction through subtraction of inputs followed by frequency specific amplification and detection.
Argues that the acausal character of the quantum mechanics discovered in 1925–26 was not a matter of chance. Rather, in the years before its discovery, German physicists, prompted by and participating in strong cultural currents antipathetic to the concept of causality, had identified the abandonment of causality as the principal desideratum for the theory to replace classical mechanics.
