Hello community.
My second stupid question.
In the book by Nouredine Zettili , the uncertaintie operators are defined as [tex]\Delta[/tex]A = A - <A>, where A is an operator, and <A> = <[tex]\psi[/tex]|A|[tex]\psi[/tex]> , with repect to a normalized state vector |[tex]\psi[/tex]>
i was wondering, why is not the uncertainty defined as: A ~ <A>, i.e., the ~ (difference operator) in place of the - (substraction operator)
