 As the professor said during class, <math>E=\(n + \frac{1}{2}\)\hbar\omega</math> starting from 0 makes it more clear what the ground state energy is than <math>E=\(n - \frac{1}{2}\)\hbar\omega</math> starting at n = 1. As the professor said during class, <math>E=\(n + \frac{1}{2}\)\hbar\omega</math> starting from 0 makes it more clear what the ground state energy is than <math>E=\(n - \frac{1}{2}\)\hbar\omega</math> starting at n = 1.

 +If it starts with n=0 for the harmonic oscillator, what about the ground state for infinite square well? 
 +As you know this <math>E_n = \frac{n^2\pi^2\hbar^2}{2ma^2}</math>, Why doesn't it begin with n=0?

 In problem 2.1 it is asked to show that imaginary energy is not possible because the wave function is not normalizable for all time, but if time is allowed to be imaginary then this isn't the case.  Is imaginary time necessary to describe particles in any physical situation? Thanks In problem 2.1 it is asked to show that imaginary energy is not possible because the wave function is not normalizable for all time, but if time is allowed to be imaginary then this isn't the case.  Is imaginary time necessary to describe particles in any physical situation?
