University College London. University of Glasgow.
He made several contributions to the field of non-relativististic quantum electrodynamics (NRQED). He obtained his B.Sc and M.Sc in mathematics from University College London in 1948 and 1949 respectivelly. His doctoral work concerned meson production from proton–proton collisions.
After his Doctor of Philosophy, he worked at University College, where became professor of applied mathematics in 1967, and fellow in 1991.
In 1953, he became a Commonwealth Fund Fellow. He then spent two years in the United States, one at Cornell University, one at Princeton University.
While at Princeton, he and John Wheeler worked on electromagnetism and gravity, resulting in the proposition of "thermal geons" in a paper published in Reviews of Modern Physics in 1957. Power then researched non-relativistic quantum electrodynamics (NRQED), particularly the interactions between radiation fields and particles, and developed several techniques.
In 1959, he and Sigurd Zienau published a paper on the Coulomb gauge and its relation to the shape of spectral lines, non-relativistic Lamb shift, and other phenomena in the Philosophical Transactions of the Royal Society of London A. Power also studied the relation between quantum electrodynamics (quod erat demonstrandum) and various optical and molecular phenomena.
In 1964, he published a book, Introductory Quantum Electrodynamics, based on a series of lectures he gave in Chile and the United States. Power retired as a professor in 1992, but remained active in research until his death following a short illness. He died on 31 January 2004, in London, England.
