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.
A close examination of the earliest phases of I. I. Rabi’s scientific life and work, through his postdoctoral research at Hamburg University with Otto Stern, 1927-29, and of the techniques for magnetic deflection of molecular beams employed by Stern and Rabi in that laboratory.
The future of science cannot be predicted by extrapolating current scientific concepts but can, to some extent, by considering the general social and cultural conditions under which scientific knowledge is being produced at present and is likely to be produced in the future.
Essay review of the proceedings of a conference called to refute postmodern intellectual positions, pointing out how ineffective the contributions are in doing so, and how largely the contributions themselves give evidence of the postmodernization of contemporary thought, including that of scientists.
This paper resumes the argument of “The Primacy…” that faith in procedurism and a low valuation of technology (relative to science) were distinctive for modernity and demarcated it from postmodernity. It extends that argument by drawing attention to the demise of disinterestedness as cultural value in postmodernity. Further, it underscores the distinction between the reality that is postmodernity and the ideology and practice that is postmodernism by drawing attention to the fact that the postmodernists’ contention that contemporary personhood is essentially and characteristically fragmented is contradicted by our exaltation of the single-minded, rule-breaking entrepreneur above all other ideals of personhood, in particular above the open-minded but rule-following scientist.
Essays identifying the features that distinguish knowledge production in postmodernity from the modern era, stressing the overproduction of all cultural goods, and the acceptance of bound and interested knowledge as fully legitimate knowledge. Direction of knowledge production by moral considerations is thus likewise legitimated, with ‘responsibility’ then appearing to gain primacy as normative category.
Catalog of an special exhibition, 1979–80, in the Dibner Exhibition Gallery of the Museum featuring artists portraits of Einstein, manuscripts by him, and apparatus connected with tests of his special and general theories of relativity – notably a large torsion balance to test equivalence of gravitational and inertial mass constructed for Lorand Eötvös (lent by Museum for History and Science and Technology, Budapest), and a 1300 Kg aluminum cylinder deployed by Joseph Weber as gravitational wave antenna.
An overview of the technique of magnetic deflection of molecular beams employed by Columbia University physicist I. I. Rabi to determine spins and magnetic moments of atomic nuclei in the years before he invented the technique of nuclear magnetic resonance.
An account of the early career of German theoretical physicist Alfred Landé, with a close examination of the process by which he came to provide a quantum-theoretical, phenomenological accounting for the anomalous (classically inexplicable) effect upon the light emitted by atoms placed in magnetic fields – together with some reflections upon the inherent impossibility of retracing the conceptual steps to a discovery.
Brief biography of this early 20th -entury Austrian theoretical physicist with appraisals of his work, in particular disparaging his highly influential What Is Life? as of little value.
Describes concept and content of a large exhibition on the history of particle accelerators and detectors, then in preparation, and on display until 1988.
Explores internationalism as an element of the ideology of scientists, and the ways in which German physicists and other scholars reconciled that ideology with nationalistic attitudes and behaviors in the decade following World War I.
Describes concept and content of exhibition on the history of atomic clocks then in preparation, and on display until 1988.
A review of the many different areas of physical research in which the electronic hardware and the microwave techniques developed in World War II radar programs were fruitfully applied after the war. Special attention is given to the question of continuity vrs discontinuity in research directions from pre- to post-war as test of disciplinary autonomy. Some 500 references given.
Illustrated narrative account of the concept and realization of atomic frequency standards, 1873–1953, and, in greater detail, of development, 1953–56, of the first commercial atomic frequency standard. This device, tradenamed Atomichron®, incorporating the first vacuum-sealed cesium beam tube, resulted from the collaboration of MIT physicist Jerrold Zacharias, and his student R.T. Daly Jr, with the National [Radio] Company of Malden, Mass.
A narrative illustrated by dramatic photographs of the exhibition Atom smashers: fifty years, on display 1977-1988.
Illustrated narrative account, elaborating the descriptive labels in a like-named Museum exhibition, 1981–82, in which was displayed the apparatus used in 1956 by Ernest Ambler and collaborators at the National Institute of Standards and Technology to confirm experimentally the theoretical prediction by C.N. Yang and T.D. Lee of the non-conservation of parity in some nuclear processes (“weak interactions”).
Gives various measures of the expansion of physical research in and following World War II and makes a broad case that it had the purpose and the result of reorienting that research toward refined and magnified effects, toward technique rather than toward concept, as this was where lay the interests of the national security agencies sponsoring that research.
Argues that the usual accounts of the discovery of diffraction of X-rays by crystals in Munich in 1912 have rationalized that discovery by reading back into the minds of the discoverers an explanation of the observed effect that none of them then held, and that was only gradually and haltingly worked out after the discovery.
An overview of the several types of atomic frequency standards with some attention to the historical sequence and context of their development.
Argues that the usual accounts of the development of quantum theory have mistakenly supposed that the problems relating to the interaction and the analogies between matter and radiation out of which the quantum mechanics emerged in 1925 were also the problems that in the preceding years quantum theorists regarded as most central and indicative for the failure of classical mechanics.
