Meanings
-
Used attributively in the names of various units, formulae etc. first devised or worked on by the German physicist Max Planck (1858–1947), chiefly in the realm of quantum theory.
As Dr. Feynman noted, there are still shorter scales of time and distance to go before we reach the ultimate limits imposed by quantum physics: the Planck length, 10^-33 of a centimeter, and the Planck time, 10^-43 of a second. Both are named for the German physicist Max Planck, who made the breakthrough that led to quantum mechanics.
