Heisenberg Indeterminacy Equation

Where does the 4 pi come from in the equation?

Re: Heisenberg Indeterminacy Equation

Delta x and delta p were multiplied to find the value. So if one uncertainty is reduced the other increases and vice versa. I think they used advanced mathematics and showed that the best was done with for the measurement of position and moment was with the inclusion of 4 pi

4 pi is a constant that was produced from an experiment. It stems from the idea that most graphs of waves involve the sine curve, which is usually graphed using pi.

Can someone run through what each part of the equation is? I am super super lost on this concept

Re: Heisenberg Indeterminacy Equation

The delta x is the uncertainty in position and the delta p is uncertainty in momentum. The product of these two are greater than or equal to Planck's constant divided by 4*pi.

If we know the position, then the momentum is uncertain, and vice versa.

Re: Heisenberg Indeterminacy Equation

What exactly do we use the Heisenberg's equation for and what does it tell us? Thanks

Re: Heisenberg Indeterminacy Equation

The Heisenberg uncertainty principle states that it is impossible to know simultaneously the exact position and momentum of a particle. So the more defined the position is determined, the momentum is less known, and vice versa.
