National Physical Laboratory of India is realized by using an absolute radiometer. For practical work, a group of tungsten incandescent lamps are used. The level of uncertainty is ± 1.3 × 10. Experimental work has been initiated to realize mole, the SI unit for amount of substance The NPL does not maintain standards of measurements for ionizing radiations. This is the responsibility of the Homi Bhabha Atomic Research Centre, Mumbai. The standards maintained at NPL are periodically compared with standards maintained at other National Metrological Institutes in the world as well as the BIPM in Paris. This exercise ensures that Indian national standards are equivalent
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
