Grey Walter and colleagues conducted the experiment in the chronometric paradigm. Furthermore, the area had feldspars and volcanic glass that would be valuable for chronometric dating. In 1976 Irving Segal revived the static universe in his chronometric cosmology. The Smiths Chronometric instruments were replaced by the magnetic type. He claimed confirmation, but generally his chronometric cosmology has not found favor. His main books "Chronometric Invariants" and "Lectures on General Relativity" were published posthumous. In 1912, he won the "world's chronometric record" of the Royal Kew Observatory.
