Why Is Thomas Preston Influential?
(Suggest an Edit or Addition)According to Wikipedia, Thomas Preston was an Irish scientist whose research was concerned with heat, magnetism, and spectroscopy. He established empirical rules for the analysis of spectral lines, which remain associated with his name. In 1897 he discovered the Anomalous Zeeman Effect, a phenomenon noted when the spectral lines of elements were studied in the presence or absence of a magnetic field. Preston reported, in an important paper published in The Scientific Transactions of The Royal Dublin Society, read on 22 December 1897, and published the following April, that he reported results more complicated than Zeeman had reported. Following this up further, he reported in a second paper in the RDS Scientific Transactions, read on 18 January 1899, and published the following June, that he had found results that were ’very startling’ and appeared ‘quite contrary to all theoretical explanations’. The full explanation had to wait for the theory of relativity and the introduction of quantum mechanics, which were to shake the rigid framework of Newtonian conceptions of absolute time and space. Preston’s results were an important step in this development.
