Web25 ago 2011 · Answer: The textbook uses h-bar, which is h with a little line across the top of it. h-bar just means h/2pi, so h/4pi is the same as (h-bar)/2. Top. 2 posts • Page 1 of 1. Return to “Heisenberg Indeterminacy (Uncertainty) Equation”. WebWe show how expansions in powers of Planck's constant {h_bar} = h = 2 {pi} can give new insights into perturbative and nonperturbative properties of quantum field theories. Since {h_bar} is a fundamental parameter, exact Lorentz invariance and gauge invariance are maintained at each order of the expansion.

WebAnswer: In physics, why is there h and h/2PI? Because there is both \nu and \omega. \nu is the frequency of a wave or rotation measured in full cycles per unit time. The symbol f is … Webthe answers.com page you mentioned uses the following formula: $$L_ {Planck} = \sqrt {\frac {Gh} {2\pi c^3}}$$ Note that there is the $2\pi$ factor in the denominator - so $h/2\pi$ may be simplified as the usual $\hbar$. They probably weren't able to type this character, or wanted to avoid terminology and symbols that are only known to physicists.
