摘要

Advances in science often start with abstract and difficult ideas ― Mendel's gene or Dalton's atom come to mind. Only much later, through defining experiments, do they become such concrete objects that one wonders what all the fuss was about. Genes have become sequences of nucleic acids, and atoms are now real things that can be manipulated one at a time with scanning probe microscopes. So it is, too, in condensed-matter physics: the phonon and the magnon were postulated as elementary quantum excitations of matter but acquired a real existence only through a brilliant set of experiments with thermal neutrons in the late 1950s. Those experiments were performed by Bertram Brockhouse and marked the beginning of a new field of spectroscopy, inelastic neutron scattering. Brockhouse ― who shared the 1994 Nobel Prize in Physics with Clifford Shull ― died on 13 October 2003.
