What is the significance of h/4 in Heisenberg's uncertainty equation?

[Chem_Mod]

With this value, you can determine the uncertainties in momentum or distance of a particle via the Heisenberg Uncertainty Principle. The main thing to take away is that the uncertainties are inversely proportional (ex. the more certain we know momentum's value, the less certain we know distance's value, and vice versa).

Is there a reason why they use pie?

[005199302]

I read that it was derived by integrating wave functions over the bell curve.

[Chem_Mod]

What the inequality says is that the absolute best you can do when determining both momentum and position at the same time is h/4π. This means that the uncertainty can be equal to h/4π or more, never less.

[Layla Manoochehri]

im confused, is it h/4π or is it h(bar)/2? or are they the same thing?

[Jennifer Guzman 4C]

im confused, is it h/4π or is it h(bar)/2? or are they the same thing?

From my understanding, They are the same thing but most physic majors tend to use h(bar)/2
