Mole (unit) and growth chamber lighting for plants is sometimes expressed in micromoles per square meter per second, where 1 mol photons = photons. In 2011, the 24th meeting of the General Conference on Weights and Measures (CGPM) agreed to a plan for a possible revision of the SI base unit definitions at an undetermined date. The 26th meeting of the CGPM, in a formal vote on 16 November 2018, approved the proposed redefinition of SI base units mole, kilogram, ampere and kelvin. One mole of a substance will have exactly specified "elementary entities" of that substance. The definition of the mole
Kavli Institute for the Physics and Mathematics of the Universe made of? What are its fundamental laws? Why do we exist?" The Institute for the Physics and Mathematics of the Universe was created in October 1, 2007, by its founding director Hitoshi Murayama and the University of Tokyo. It is funded by the Japanese Ministry of Science, as a part of their World Premier International Research Center Initiative. In 2012, the IPMU received an endowment from the Kavli Foundation and was renamed the Kavli Institute for the Physics and Mathematics of the Universe. Many notable scientists are employed at the IPMU. Among them: Kavli Institute for the Physics and Mathematics
