How do you calculate this sumbitch?

>>	Anonymous Sat Oct 1 17:06:05 2011 No.3833469 multiply p by p

>>	Anonymous Sat Oct 1 17:31:05 2011 No.3833636 i enjoyed this thread. >>3833612 thats quantum mechanics, jip. just look at it! you dont get to use psi in any other physic.

>>	Anonymous Sat Oct 1 17:31:05 2011 No.3833638 You calculate the norm associated with your function space on the element represented by p^2

>>	Anonymous Sat Oct 1 17:32:05 2011 No.3833644 >>3833549 I'm 95% certain that psi should be the complex conjugate.

>>	Anonymous Sat Oct 1 17:32:05 2011 No.3833647 Since p is hermitian, you can simply compute it as the norm of <span class="math">p \|\Psi\rangle[/spoiler].
