The Aharonov-Bohm Effect (Lecture Notes in Physics, Vol. 340) by M Peshkin and A Tonomura Springer-Verlag: Berlin-Heidelberg-New York-London-Paris-Tokyo-Hong Kong, 1989 vi+152 pages: price; DM 39 (Hard cover); ISBN 3-540-51567-4 Faraday and Maxwell introduced the concept of the electromagnetic field to describe electromagnetic effects in a space-time region - thereby unifying electrical and magnetic phenomena. The field strength Ff. describes electromagnetism. In 1959 Bohm and Aharonov presented a paper In which they pointed out the signi ficance of electromagnetic potentials in quantum theory and actually suggested. Interference experiments to detect how potentials would affect the passage of electrons through field free regions. In a multiply connected, region even if F^=o everywhere, there are physical experiments for which the outcome depends on the loop integral: OA^dx'^ he around on unshrinkable loop. It has been realised that in fact only the phose factor exp (i0A,dxe) in meaningful and phase invariance (gauge invariance) is the correct quantum mechanical, characterisation of electromagnetism. The idea has in recent years been generalised by replacing the simple phase of complex numbers with more complicated phase-an element of a Lie group. Few effects in physics have the distinctions of going through extensive debates and experimentations to settle the nuances as in AB effect. The contro versial aspects of AB effect concern mainly its interpretation. To quote Bohm "Now in my view, the fact that our informal discussion of interaction in terms of forces has been shown to be irrevalent implies the need, for a new kind of informal discussion of this question. -

The history of this field is well summarized in the proceedings of the Conference on 35 Years of Electron Scattering held at the University of Illinois in 1986 to commemorate the 1951 experiment of Lyman,Hanson,and Scott; this experiment provided the first observation of the finite size of the nucleus by electron scattering [Ly51,Il87]. Hofstadter and his colleagues,working in the High Energy Physics Laboratory (HEPL) at Stanford University in the late 1950’s,beautifully and systematically exhibited the shape of the charge distributions of nuclei and nucleons through experiments at higher momentum transfer [Ho56,Ho63]. Subsequent experimental work at HEPL,the Bates Laboratory at M.I.T.,Saclay in France,NIKHEF in Holland,and both Darmstadt and Mainz in Germany (as well as other laboratories),utilizing parallel theoretical analysis [Gu34,Sc54,Al56, de66,Ub71],clearly exhibited more detailed aspects of nuclear structure. Experiments at higher electron energies and momentum transfers at the Stanford Linear Accelerator Center (SLAC) by Friedman,Kendall,and Taylor,together with theoretical developments by Bjorken,for the first time demonstrated the pointlike quark–parton substructure of nucleons and nuclei [Bj69,Fr72]. This work played a key role in the development of modern theories of the strong interaction. -

DAVID JACKSON AND KURT GOTTFRIED ICTOR FREDERICK WEISSKOPF was a major figure in the golden Vage of quantum mechanics, who made seminal contri- butions to the quantum theory of radiative transitions, the self-energy of the electron, the electrodynamic properties of the vacuum, and to the theory of nuclear reactions. In the broader arena through his writings and actions he was an effective advocate for international cooperation in sci- ence and human affairs. In 1981 he shared the Wolf Prize for physics with Freeman Dyson and Gerhard ‘t Hooft for “development and application of the quantum theory of fields.” In 1991 he was awarded the Public Welfare Medal of the National Academy of Sciences “for a half-century of unflagging effort to humanize the goals of science, acquaint the world with the beneficial potential of nuclear technolo- gies, and to safeguard it from the devastation of nuclear war.” As a member of the Pontifical Academy of Sciences he was instrumental in persuading the Pope to speak on the dangers of nuclear weapons. Weisskopf was born in Vienna, Austria, on September 19, 1908. -
