## Main Question or Discussion Point

**infinite potential well and the uncertainty principle**

the solution for Schroedinger equation in infinite potential well satisfy the following

energy levels:

where l is the width of the well.

E can't be zero since then [tex]\psi[/tex]=0 so there isn't any particle in the well . i read in

a book that "there is a tight connection between this fact (E[tex]\neq[/tex]0) and the

uncertainty principle", what exactly is the connection?
