Could someone explain the Uncertianty Principle?
Please and Thank you!

It would probably make sense if you check out wikipedia and the PhysicsForums faqs on the subject:Could someone explain the Uncertianty Principle?

Note that this has nothing to do with the HUP. The HUP isn't a "measurement technique" limitation.If we can affect the particle by shining photons onto it, then can we affect it in a predictable/measurable way?
It is wrong, this is a leftover explanation (from the early days of QM) that is thrown around as a simple way to avoid further explanation. But still wrong. There are several ways to see this.I got my definition from 'A brief history of time', which I have just got out again to see if I remembered it correctly. It clearly states here, that it is only due to the fundamental uncertainty created from bouncing photons off the particle. Are you saying it's wrong, or that it is not giving the full picture?
I know that in quantum theory, we have to assume that an electron/other particle is in all states until it is observed (like schrodinger's cat), but I assumed that the uncertainty principle was only a restriction on the measuring of that particle.
