what quantum mechanics means to you
    #5466102 - 04/01/06 01:03 AM (18 years, 2 days ago)

Does quantum mechanics tell us that the universe is the unfolding of all possible, deterministic states ("indeterministic" in a sense) and has science discovered the physical system where reality branches off? Some interpretations of quantum mechanics say that the branches are only known once they have entered the conscious domain of an experiencer.

You exist in your current universe because of a sequence of events whose reality is only statistically determined. The other branches have equal likelihood of being realized and some interpretations of quantum mechanics show that if light behaves like a wave when its position is unobserved, it can be thought of as all possible trajectories existing simultaneously. Thus the unobserved universe exists in a superposition state.

Am I in a superposition state in your universe?

Quantam mechanics doesn't mean much of anything to me. It has been stated that, unless you understand the underlying mathematics of quantam mechanics, you don't really have much comprehension of what quantam mechanics is. Any way of describing quantam mechanics without the accompanying mathematics is more in line with metaphors to convey general notions.

Exactly. I am not personally adept in mathematics in general, certainly not the mathematics responsible for quantam mechanics; thus, quantam mechanics does not mean much of anything to me (as I stated). :grin:

I'm glad to see that someone here is capable of following through with basic logic to reach a conclusion. "If an understanding of the mathematics behind quantam mechanics is necessary in order to actually know what quantam mechanics is, and I have stated that quantam mechanics doesn't mean much of anything to me, then I..." :lol:

I can definately say that I don't have a grasp on quantum mechanic, most people don't, but there are physicists and researchers around the world learning a bit more everyday, things like matter in its bassest form is a particle and a wave... defies pervious notions of science.

So the one definate thing I can say about quantum mechanics to me is that it shows me and most people that reality is far more than what we think it is and we have yet to comprehend even the scope of it.

I dont think you need to know the math in order to understand the concepts of QM. I have read a couple books on it and I have hung in discussions about QM/QP with college students who actually have studied the math. Granted I havent had a highball with Feynman and told him how ridiculous his many worlds theory is, but I like to think I have a more advanced grasp on QP/QM than your average person.

Take the Young Slit experiment, besides having the coolest name for an experiment, there is no math involved whatsoever, it is simply using previously stated and known laws of how waves act and the observation of observation of events.
Of course it can all be represented in a mathematical function, but so can Schrodingers cat, which is also just using a little logic and entanglement.

I think that QM/QP just lets us know that what we thought was real....really isn't.
And what we thought was not real....is just as real as what we thought was real.

That our life is really just a creation of our own imagination.

quantum mechanics was cool til i had to take a class on it

now its just a ton of calculus that is somehow supposed to relate to a bunch of abstract ideas and wave functions and eigen functions and to be honest, i just cant connect the math to what is actually happening

and even the non math part doesnt really make any sense to me...how can it go from one level to another without ever being in between them?


How can there be zero nodes in the particle in the box wave, so it cant exist at one point, but can exist at points on either side of the node? How does it get from the first part to the second without crossing that node??

oh man and thats just like the very beginning of the things that make no sense to me regarding that subject

so yea....i just dont get it  :confused:

Quantum Mechanics is the true definition of chaos.

There is absolutely no predictability of where a quark will end up next in the subatomic realm - you can know it's velocity and position - but never both at the same time. And since these quarks do not have a solid structure, it is possible a quark from another packet of energy (a proton, neutron, electron) to transfer to another. Thusforth, it is possible that a solid object can pass through another without damaging either.

Another interesting factor is the relativity between the microscopic and the macroscopic realms. There's a very fine line between the two. While the movement of your hand is a large event in the subatomic realm, hence all the quarks have just moved a very great distance, in the big picture of the Milky Way, pretty much nothing has happened. And in the prospect of the universe, the Milky Way is the size of an atom, and is minimalistic. Yet, to us, just like the quarks relate existence in our hand, it is unfathomably big.

Im just saying, you had credibility up to that point, henceforth the second paragraph was read in jest hitherto the nonsensical word, thus the aforementioned topic hurt your arguments.

No, QM shows that there is only predictability in the quantum world. Not that there isn't any at all. On the contrary - we can predict things in the quantum world to a very high degree.

What QM suggests is that our concept of something being in a well-defined and specific position does not work on the quantum level. It's not that we can't predict exactly where a particle is or how it is moving...the particle just isn't anywhere "exact", nor is it moving in any "exact" direction. The particle is probably in a certain location (or a certain set of locations) and is probably moving along a certain vector.

In fact our entire idea of "particles" is probably outdated and entirely wrong. Electrons and such are not tiny balls of anything. Though I doubt any human can say exactly what they are, I would tend to think of them more like waves than the classical idea of a "particle". Not exactly waves - like water waves - though...more like discreet packets of wave-like geometries. This, I think, is where the problem of defining exact location/velocity in the quantum world comes into being - because such concepts simply don't exist on such small scales.

So one grammatical error voided the whole validity of my argument, even though you knew exactly what I'm talking about? Maybe you should find a spelling nazi forum to post in kid, I'm here to discuss philosophy, not get my papers graded in an English class.

jeez, calm down, take a joke.

on the other hand.... your grasp on QM, and your argument so far seemed based solely on one viewing of "The Elegant Universe".
