(*) this value.
This value is found cubed in the denominator of Rydberg's constant. A "reduced" form of this value is found by dividing it by two times pi and is used in calculating the angular momentum of a subatomic particle. The Heisenberg uncertainty principle is typically written as the change in position times the change in momentum is greater than or equal to (*) this value. For 10 points, name this constant equal to about 6.626 times ten to the negative thirty-fourth power, named for the German developer of quantum theory.
