# Formulation of Quantum Mechanics?

That equation is simple a formulation of the uncertainty principle. The uncertainty in position times the uncertainty in momentum must be greater than or equal to a constant divided by 2.

Okay... next question.
Whats the uncertainty principle?

I started answering this, but my explaination was bumbling. The introductory text from the following does a better job.

Possible clarifications with respect to the symbols used are that $\hbar$ is just a number, and in the wiki article above <> is used to denote an average.

That helps a lot! Thank you! ^.^
