On the Study of American Biology and Medicine: Some Justifications
(Johns Hopkins University Press, 1964)
The Place of George M. Beard in Nineteenth Century Psychiatry
(Johns Hopkins University Press, 1962)
Charles Benedict Davenport and the Beginning of Human Genetics
(Johns Hopkins University Press, 1961)
Ordered Expansions in Boson Amplitude Operators
(American Physical Society (APS), 1969)
The expansion of operators as ordered power series in the annihilation and creation operators a and a † is examined. It is found that normally ordered power series exist and converge quite generally, but that for the case ...
Density Operators and Quasiprobability Distributions
(American Physical Society (APS), 1969)
The problem of expanding a density operator ρ in forms that simplify the evaluation of important classes of quantum-mechanical expectation values is studied. The weight function P ( α ) of the P representation, the Wigner ...
The Quantum Theory of Optical Coherence
(American Physical Society (APS), 1963)
The concept of coherence which has conventionally been used in optics is found to be inadequate to the needs of recently opened areas of experiment. To provide a fuller discussion of coherence, a succession of correlation ...
Mesmerism and the End of Enlightenment in France
(Harvard University Press, 1968)
Some Problems in Planetary Atmospheres Involving Collision Processes
(American Physical Society (APS), 1967)
A brief selection of problems occurring in the interpretation of planetary atmospheres, the resolution of which demands a knowledge of atomic collision processes, is presented. The selection is largely arbitrary.
Dipole Properties of Molecular Hydrogen
(AIP Publishing, 1969)
Experimental data on electron scattering, optical refractivity, and molecular anisotropy are used to construct a model dipole spectrum for molecular hydrogen which is consistent with oscillator‐strength sum rules. The model ...
Atom—Atom Collision Processes in Astrophysics: Theoretical Studies
(American Physical Society (APS), 1967)
Theoretical studies of atom-atom collision processes which may be relevant to the interpretation of astrophysical phenomena are reviewed. Work on excitation, ionization, and electron capture in atomic hydrogen by fast ...
