Two things. One, I don't understand the difference between a particle and a wave. Something about predicting their location or whatever. I don't get it. Two, I don't understand how this photon property affects our entire reality. Light is light. Relatively little is light. I mean pure light.
Your entire life depends on photons, you can't live without them. They transfer energy from the sun to the plants on Earth (and indirectly, to the animals that eat them).

Ah! Thank you. And of what importance is the photon in our physical reality? What is its place?

I like using this video to illustrate the phenomenon:
Dr Quantum - Double Slit Experiment
www.youtube.com/watch?v=DfPeprQ7oGc
www.youtube.com...
So that proves it's got nothing to do with consciousness, though there are no shortage of "snake oil salesmen" peddling their "snake oil theories" in an effort to convince you otherwise.
An important aspect of the concept of measurement has been clarified in some QM experiments where a single electron proved sufficient as an "observer" — there is no need for a conscious "observer".

he has it backwards.
the photon behaves like a probability wave, until it is not only observed, but the observation is recorded as collected data, then it behaves like a particle. the act of recording the data, collapses the probability wave function.

Any scientist worth their salt understands that -nothing- in science is taken on faith.
So no, science is not a religion. It is a tool of understanding based on exploration, experimentation, and explanation.
sure? if I say Einstein was wrong, QT is BS, wouldn't they crucify me ?
that's what I'm thinking...

Is this your video?
No. It has nothing to do with evolution or creationism.edit on 201311America/Chicago11pm11pmFri, 01 Nov 2013 18:06:54 -05001113 by OneManArmy because: (no reason given)
Well, I'm not so sure, that's why I put in both videos. In fairness for the OP and other posters they did not both appear at the same time, it took a moment or so to add the second URL.
the second video is the correct video.
But in answer to the question posed by the OP...
To some people yes science has become a sort of faith.
And to some people the Bible is the literal word of God.

Did you ask a biologist, a chemist, or a physicist? There are important distinctions amongst the disciplines. This is my biggest gripe with people like Neil de Grasse Tyson. He is actually quite educated in his field, but when he starts to stray into areas like biology or anthropology, he makes a right dog's tooth of himself, and sets back popular scientific understanding with his musings.

matter-wave duality is BS
reply to post by KrzYma
You have no understanding of this at all. There is no dogma in this case. Science just says if you do experiment A you get result A-R, and if you do experiment B you get result B-R. In fact this is the one thing that everyone agrees on.
We have models that try to explain why the experiments happen this way, and they work well, but applying the models doesn't require a fundamental understanding of the nature of a photon anymore than applying gravitational models requires a fundamental understanding of the nature of gravity. In the case of gravity, Newton famously presented a model which worked perfectly for centuries, while clearly stating he did not presume to understand the cause of gravitational attraction.
So there is no religion, belief or dogma in saying 'here's the experiment we did and here's the results we got, and here's a model that predicts what will happen on other experiments', when all three have been proven true so far.
But ask real physicists what the true origin of wave-particle duality is, and they will probably tell you that the person who figures that out will get a Nobel prize. This is exactly the opposite of the religion the guy in the OP video is preaching, because he says he has the answer. So he's the religious one, but he's considered a crackpot by other physicists so if you're using him as a sample of a physicist, you picked a bad sample.
I guess there are a few crackpots in any field.edit on 1-11-2013 by Arbitrageur because: clarification

i asked a physicist. it was bordering on data overload.
as far as physicists go, have you seen this?
