Example Sentences
- "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."
