### Heisenberg's Uncertainty Equation

Why does the solutions guide have the uncertainty equation as (delta)p(delta)x = (1/2)h but Lavelle taught it as (delta)p(delta)x >/= (1/4pi)h?

### Re: Heisenberg's Uncertainty Equation

So the original equation for Heisenberg's uncertainty principle is actually (delta)p(delta)x = (1/2)ħ just as the solution's manual says. However there is a difference between ħ,an H-bar, and h, Planck's constant. 'ħ' can be reduced to planck's constant as seen as: h/2π. Multiply (1/2) and h/2π together and you get h/4π just as Lavelle taught it.
