The anomalous magnetic moment of the electron is of great significance in the study of elementary particles and quantum electrodynamics. The history of its discovery is in large part the story of a technique:—the use of molecular beams—which was not invented for the specific purpose hut which did, by permitting a discrepancy to appear where none was expected, answer an unasked question.

Magnetic intensities thousands of times as great as one usually achieves with magnets are made by explosively compressing field lines. The fields can be applied to superconductivity, thin‐film research and attempts at nuclear fusion

Each time physicists think they've found the fundamental building blocks of matter, they discover that the blocks themselves have a structure. Now it seems that the blocks may be quarks—with three different kinds you can build all known mesons and baryons and fit them into symmetrical arrangements of 8 or 10 particles.

Participants at a topical conference are hopeful that quantum field theory may elucidate the symmetry and interactions of the smallest bits of matter

Better measurements and improved theory are stimulating increased attention to processes in which photons eject electrons from the atoms in which they originate. Experts now concentrate on such matters as spins, parities, angular correlations and oriented nuclei.
