Scientists from Georgia Institute of Technology, California Institute of Technology and the University of Southern California have uncovered an astonishing parallel between the mathematics of celestial mechanics and the math governing some aspects of atomic physics. For instance, celestial bodies move in paths according to their mutual gravitational attraction, creating tubular "highways" in the space between bodies.
Reliable calculations for fluorescence yield and x-ray emission rates based on atomic physics are readily available (6,7,8,9).
50 YEARS AGO: Prof M L Oliphant addressing the Radio Industries Club of Birmingham yesterday said that an American had recently expressed to him the view that the day of the radio amateur was passing and that the future might see technically-minded boys applying electronics to the study of nuclear or atomic physics because that was more interesting than the problems of communication.
In addition, scientists made further advances in atomic physics.
In the 1934 publication of Atomic Theory and the Description of Nature, Bohr first develops his ideas about complementarity as the core of his philosophy of atomic physics. The two other collections, Atomic physics and Human Knowledge (1958) and Essays 1958-1962 on Atomic Physics and Human Knowledge (1963), represent refinements of the basic philosophical positions of the earlier volume and a further branching out into other disciplines as they related to physics.
He covers the role of singular solutions of quantal equations in atomic physics, the classical description of crossings of energy terms and of charge exchange, classical stationary states, understanding the role of the singular spin-spin interaction in the binding energy of two-electron atoms/ions, the last observed line in the spectral series of hydrogen lines in magnetized plasma: s revision of the Inglis-Tellor concept, and extrema in transition energies resulting not in satellites but in dips within spectral lines.
He summarizes the necessary theoretical background for research for students of physics and chemistry, including information that might be strong in one of the disciplines but weak in the other, that is basic quantum mechanics and atomic physics for the chemists and some basic knowledge about molecules for physicists.
In line with this, researchers in Atomic Physics and Packaging Logistics developed a new laser instrument that could solve the problem.
In subsequent years, he applied his extensive experience in spectroscopy, atomic physics, and beam physics to Scrape-off Layer (SOL) and divertor physics issues in tokamak plasmas.
Carl Wieman's contributions have had a major impact on defining the field of atomic physics as it exists today.
