Max Karl Ernst Ludwig Planck, FRS[2] (/plÉËÅk/;[3] 23 April 1858 â 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918.[4]
In physics, the Planck length, denoted âP, is a unit of length, equal to 6965161619900000000â 1.616199(97)Ã10â35 metres. It is a base unit in the system of Planck units, developed by physicist Max Planck. The Planck length can be defined from three fundamental physical constants: the speed of light in a vacuum, the Planck constant, and the gravitational constant.
