Questions with Heisenburg uncertainty principle

What does the value (delta)x and (delta)p represent when using the Heisenberg uncertainty principle? (interpretation of meaning) And why is it important?

Re: Questions with Heisenburg uncertainty principle

delta x is the uncertainty in position as we do not know exactly where an electron is at a given time. Delta p is the uncertainty in momentum which is derived by mass x velocity because we are not sure about the velocity.

Re: Questions with Heisenburg uncertainty principle

These are important because the more you know about the position (delta x) of an electron, the less you know about its momentum (delta p), and vice-versa. Thus, it's impossible to know both an electron's position and momentum.
