I'm off to look at the kitty cat thread, hurts my brain less!

ahh, thread brings back uni memories

Well it really just proves how much science knows about reality and things = nothing...lol

a lot of experiments are based on observation. So as suggested by this vid we are changing the outcome and therefore the experiment is invalid...or at least the result is.

Never had much faith in physics and yes i studied it at A level and university.

You studied physics at university and yet you believe that sciences knows "nothing" about reality? Quantum mechanics is one of the most predictively accurate theories in physics. It just happens, however, that it's a probabilistic one.

Lay people sometimes see it as a failure because it doesn't tell is what us actually "going on", but that's entirely beside the point (and indeed such a question is quite probably meaningless), as spp points out:

I'd argue it shows there is far more to the universe that we live in, than the one we see day to day. Thinking of particles as having wavefunctions, is really just a mathematical model that allows us to predict what will happen next. These videos/and books tend to speak in analogies, as that is the only way to explain what the maths is telling us. To get to hung up on what is actually happening is a bit misleading. These mathematical models have worked well enough for us to use them to build many of the modern things we see today.

Absolutely. Science is not an ontological endeavour; its purpose is to construct models that can be used to predict, and quantum mechanics does that admirably. A good example of a technology derived from our understanding of QM is the transistor, without which there'd be no such thing as the modern computer.
