Reduced Planck's constant \hbar

#

The reduced Planck's constant \hbar is defined as a positive real number with the value 1.054571817×10341.054571817 \times 10^{-34} in units of Js\text{J} \cdot \text{s}.

theorem

>0\hbar > 0

#ℏ_pos

The reduced Planck's constant \hbar is strictly positive, i.e., 0<0 < \hbar.

theorem

0\hbar \ge 0

#ℏ_nonneg

The reduced Planck's constant \hbar is non-negative, i.e., 00 \le \hbar.

theorem

0\hbar \neq 0

#ℏ_ne_zero

The reduced Planck constant \hbar is not equal to zero, i.e., 0\hbar \neq 0.
