Llewellyn Thomas
Llewellyn Hilleth Thomas (21 October 1903 – 20 April 1992) was a British
physicist and
applied mathematician. He is best known for his contributions to atomic and molecular physics and solid-state physics. His key achievements include calculating relativistic effects on the spin-orbit interaction in a hydrogen atom (
Thomas precession), creating an approximate theory of
-body quantum systems (
Thomas-Fermi theory), and devising an efficient method for solving tridiagonal system of linear equations (
Thomas algorithm).
