Yes, but observation in this context does not refer to a consciousness measuring or perceiving the wave function but rather anything which interacts with the wave function (and so could be used to determine the position or the particle, but it's irrelevant whether any sentient mind does this). The new age metaphysicists use this ambiguity of language to imply (or outright claim) that the experiment shows that the mind has special, magical power. It doesn't, or at least, not in the sense that the new age metaphysistcs want. The special power of the mind is to observe the startling and unexpected results of the double-slit experiment and perceive in it the counter-intuitive nature of reality.

the trick is, how do you measure which slit a particle goes through? it's not like you can just set up a camera - you'd need to bounce a photon off of it, or absorb it in a detector on the far side of the slit. "Observation" of a particles implies a physical effect on the observed particle.

Imaging you're videotaping a marble on a pool table. Not bad. You know exactly what that marble is doing, where it is and how it's moving. You have total information about that marble.

Now suppose you could only detect information on the pool table WITH that marble. So, like, if there were a sturdy wooden square in the middle of the pool table, the only way to see it would be to bounce a marble from one end of the pool table and see where it hits the pool table walls. A bit tricky, but you can figure out where the wooden square is and even figure out it's a square by using geometry.

Now, imagine you could only find marbles on the pool table using other "detector" marbles. For ease of understanding, pool table marbles are "Pmarbles" and detector marbles are "Dmarbles." You could bounce the Dmarble against the Pmarble, but then the Dmarble's speed is affecting both where the Pmarble is and also its speed on the pool table. So when you try to detect it, you get nowhere.

The analogy is thus: think of a Pmarble as any low-mass particle (like an electron) and the Dmarble as a photon. When you need to observe something, you throw a photon at it then read the photon in a detector.

That movie "What the Bleep do We Know" really messed up my understanding of Quantum Mechanics. I didn't understand it at all until I took a Modern Physics course in college. Now I understand it just a little bit.

Consciousness is a Transcendental Paradox. The quantum mechanics gets to Consciousness, the spookier and more paradoxical becomes. In fact, QM proves - but not scientist would dare admit for fear of losing their job - that fundamentally there is only One Consciousness, one great Unity from which we all spring like branches from an Infinitely bifurcating tree - the Tree of Life.

QM is the Yin and Yang -- it proves that Consciousness creates Reality, and yet also proves that Reality creates Consciousness. In fact, there can be no such distinction; Consciousness *is* Reality, and Reality *is* Consciousness. When we study subatomic particles, we study the fabric of Consciousness; when we look inside our minds with meditation, we study the fabric of Reality. Fundamentally there can be no distinction between Science and Mysticism to the enlightened, just as Yin is Yang and Yang is Yin. Each are mutually Recursive to Infinite depths, like Eval and Apply.

>>6726745
This is probably the best explanation I've heard.

I'd liken it to more mundane observations that alter the experiment, as well.

Using a thermometer to take the temperature of a hotter substance would require some heat to flow into the thermometer and be used to rise the mercury, lowering the temperature of the hotter substance a little bit.

So, when we try to take the temperature of something, we're changing it. And it has little to do with consciousness altering the fabric of reality.

What is this consciousness bullshit?

This is how I think of this (I could be wrong). When there are no interactions between the electron passing through the double slit, it is free to propagate through both slits and create an interference pattern. If you try to figure out which slit the electron goes through, you have to bombard the electron with something (photon or other particle) to detect it. By bombarding and detecting it, you collapse the wave function of the electron down to a degree where it can either propagate through one slot or the other but not both which destroys the interference pattern.

I probably gave a half assed explanation but it has nothing to do with consciousness.

Okay I'll try answering the question.
Everything you haven't measured is uncertain, subjectively.
Particles which behave randomly determine themselves because they aren't guided through physical interactions with other particles, but particles are dumb, so they just flay around randomly until they hit something.
Once they get interacted with, they become more focused and guided, thus reducing the randomness factor.
I reckon that if our "observation devices", which are just particle shooters that collide with other particles, were consistently accurate enough, we could actually direct the particles going through slits into a single point.

So all in all, the only things that determine reality are interactions, randomness is just unguidedness, observer uncertainty comes from not having interacted yourself.
We can't be certain about everything because there's just too many things to be certain about. You could build a super computer which would calculate and predict every movement on Earth, but then once a random interstellar interaction happens, like radiation waves, everything on Earth would get subtly affected, thus forcing the computer to start gathering data from the scratch in order to start making accurate predictions again.

I hope this answered some questions, I may or have not may have gotten a little sidetracked.
