Magnesium silicate perovskite, the most abundant mineral of the Earth has been named after physicist Percy Bridgman who was awarded a Nobel prize in 1946 for high pressure physics. It has been approved (IMA 2014-017) by the Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association (IMA) after being found in tiny fragments in shock veins of the Tenham meteorite
