I am a Christian. Although I have an abiding interest in science and philosophy, I view things from a distinctly Christian vantage point, which harmonizes human well-being with what we know of the natural world.

Here's a nice quote I came across:

"The spectacle of the universe seems all the more grand and beautiful and worthy of its Author, when one considers that it is all derived from a small number of laws laid down most wisely." -Maupertuis, 1746

comment Why doesn't Ehrenfest's theorem work for a particle in a an infinite square well?
Do you mean that the behavior of $\langle x\rangle$ depends on the initial conditions? I could accept that, as it would make sense. I'm a little confused over your first sentence. If you had used the words "initial conditions" in place of state, I would understand it. Is that what you mean? (I guess I don't know what the word "state" means exactly, in the context of QM).

comment Chaos theory and determinism
@Thriveth: On subsequent thought, I have to take back what I said about the connection between chaos and free will, since they may not have anything to do with each other. However, I do believe that free will (in some qualified sense) exists, regardless of whether we can define it or not. That's just my position.

Thanks for your answer. You say "Consequently, ⟨x⟩ will oscillate in an interval that is a proper subset of the well i.e. shorter than the well." However, Griffiths obtains stationary states for the infinite square well. What am I missing?

@Chris: That's just a typo. My main concern is the swapping of a $\partial x$ for a $\partial t$ in the third line.
