Quantum Physics for dummies

Online videos are an integral part of our online experience, and finally they have their own section on the board.

Quantum Physics for dummies

This 5 minute video by Robert Anton Wilson ( http://en.wikipedia.org/wiki/Robert_Anton_Wilson) is very powerful. He has a very unique way to express stuff we have discussed on this board many times.

Thanks for that Natalie, nice presentation - I can't see your selected quotes now ...lol from my perspective in my own reality tunnel editing this post ...
But I liked that discussion he had about that - the reality tunnels.
and '
Any model we make does not describe the universe, it describes what our brains are capable of saying at this time.
and
"All perception is gamble. ... we believe what we see and then we believe our interpretation of it.



There's an excellent sort of discussion about this perception (speaks of being in a warehouse with a torch light) in webwanderer's latest nde thread.

............

This is from a programme I watched last night also about quantum physics on multiple universes (multiverse) and dimensions and has our universe been set up for us - full transcript and video story here, it's only a couple of minutes long and worth the viewing.
http://www.abc.net.au/catalyst/stories/3245822.htm





What makes our universe just right for our existence? It could be that the universe we call home is one of many, just a small part of a huge multiverse. Graham Phillips looks into various multiverse theories and highlights the difficulty in proving the theories. However, there are high hopes that CERN's Particle Accelerator will turn those theories into reality.......

(..... good stuff before this bit but this bit below intrigues me)

Professor Lawrence Krauss
The other possibility for a multiverse comes from recent ideas from particle physics which suggest perhaps that there may be extra dimensions in nature. And it's possible that there could be other universes, literally a millimetre away in an extra dimension, and we wouldn't know about it.

NARRATION
Remarkably, the atom-smasher at CERN could find them. Physicists would go wild.
.........

(and this... )

NARRATION
In the many worlds theory, for every one of us, there is a multitude of duplicates.

Professor Lawrence Krauss
So there are an infinite number of other universes, quantum universes, but I pick the one I live in by observing it.

NARRATION
Confused? Well maybe an analogy will help.

Dr Graham Phillips
When you toss a coin, conventional thinking says it lands on either heads or tails. But imagine just before it lands, the world splits in two. In one world, the coin lands on heads, and in the other, it's tails. That's the essence of the many worlds interpretation.

Associate Professor Andrew Greentree
Any time there could be multiple outcomes, different measurement results that we can observe, then both of those results actually occur.

Professor Ray Volkas
And so in a sense, we also split into different versions of us.

Associate Professor Andrew Greentree
Then there must be other copies of you. Other copies of me, having this conversation in slightly different ways.

Professor Lawrence Krauss
There could be an infinite number of Graham Phillips. There could be an infinite number of me. There could be a universe in which I'm interviewing you.

NARRATION
Could we ever meet our double?

Associate Professor Andrew Greentree
This is something that everyone thinks about. We don't talk about it very much in our lectures. We don't tell our students about it. Um, but it is something that we think about.

NARRATION
Excitingly, it can't be absolutely ruled out, and in case you're wondering, quantum physics is no fringe theory.

Professor Ray Volkas
It's an incredibly successful theory, and quantum mechanics has never been falsified.

Associate Professor Andrew Greentree
What gets me, the more I've gotten into quantum, is the fact that it actually makes sense to me now.

Dr Graham Phillips
So there's no shortage of multiverse theories - in fact, an embarrassment of riches, really. How can we prove these other worlds exist if we can never visit them?

Professor Brian Schmidt
So the problem with this idea of the multiverse is it sounds great, but you've got to be able to test things. So you know, we have science, we have metaphysics. So metaphysics is sort of, you know, it seems good, but we have no way of testing it.

NARRATION
But soon, we may be able to separate the multiverse from the metaphysics, by coming up with a brand new theory that explains our universe very well.

Professor Lawrence Krauss
Maybe it explains everything that we can see, but one of the predictions is also that there are other universes that we can't see, we probably say it's physics. Because we say it explains everything we see, so the predictions we can't see, we're willing to believe.

NARRATION
Then the mystery of why our universe seems to have been set up for us would have been scientifically solved.

Excellent video, thank you.

What can you do with a doctorite in quantum physics? I am planning on going to college soon. I'm smart and I love to learn. Whatever I do I want to make sure I get a doctorite. To specialize in medicine is the safest and best route for me to take - thus far. But physics has always interested me, even more so quantum physics. Even electrical engineering sounds terrific.
