Hi liboff proble 5.28 says
time dependent schrodinger equation permits the identity such as [itex] E = i\hbar \frac{\partial}{\partial x} [/itex] (E is operator)
But i don't understand E( is operator in this problem) can be thought energy operator
Is energy operator only H, Hamiltonian?
If E is energy operator, We can find some uncertainty by using commute relation
[tex]\Delta E \Delta t = \frac{1}{2} \hbar [/tex]
Considering this relation, We can think if we know current energy eigenstate, meaning we
know exact energy value, uncertainty of t,time is indefinity.
What does it means? we can't find exact time that state measured experienced?
what does it means?Please remove my confuse.
Thank you.
