hbar or hbar/2??
Regarding the uncertainty principle, some books say
(delta p) (delta x) >= hbar
and others say
(delta p) (delta x) >= hbar/2.
Which is right? This matters because I get different results when I
let p x=hbar(or hbar/2), plug into the expression for energy, and
minimize it to get the ground state energy of the system.
