I am stuck on one part of my Quantum Mechanics HW. Above the question it says "Try and answer the following question." So I can only assume that he isn't looking for something incredibly detailed. (Ill explain why after the question is given.)(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

What is the meaning of the uncertainty relation [itex]\Delta \overline{x}\overline{p}≤\hbar /2[/itex] associated with the commutation relation [itex][\overline{x},\overline{p}]=i \hbar[/itex](The bars over x and p are supposed to be hats, as in a unit vector but I do not know how to do them with Latex.)

3. The attempt at a solution

At this point in time we only had one class and the whole first chapter of the book doesn't delve much into either one of these relations. It says that

[tex][\overline{A},\overline{B}]=AB-BA[/tex]

That is really all I know about this relation. There is nothing in the lecture notes and nothing about these relations until Chapter 3. Can anyone lead me in the right direction?
