quantum mechanics? i saw a tv show the other day about this woman who had a robot copy of herself made, but when she finds out, she says that's impossible because it violates quantum mechanics, i thought that quantum mechanics dealt with extremely small particles! can someone explain this to me?

Quantum mechanics..................? Hey So ive been learning a bit about Quantum mechanics, and i was wandering, what causes the Atom to change its whereabouts if you observe it? its as though it knows we are Observing it.

What is the difference between quantum physics and quantum mechanics? Are they synonyms? What would you expect to study on a college course called quantum physics? And in one called quantum mechanics?

How did Einstein give birth to quantum mechanics? I've read that Einstein is the father or grandfather of quantum mechanics, even though he was against it. How did that happen? What theory of Einstein's opened up the world of quantum mechanics? I know that Einstein was a firm believer of a clockwork universe. In his own words "God doesn't play dice with the universe." So how did Einstein's clockwork universe become uncertain? Mostly based on probability? The next person that gives me a nonsense answer like miketherex is getting reported. Please be serious.

How is Relativity realted to Quantum Mechanics? The theory of relativity directly relates the four dimensions of our universe (time, motion, space, and the speed of light). Quantum mechanics is the study of measurements in extremely small quantities. I understand that if you distort one dimension of the universe, another must be distorted as well. But how does this relate to Quantum mechanics and how does it branch off from the M-Theory?

What are a few arguments one can use against quantum mechanics? This question may sound a little weird. I want to know if there are shortcomings in quantum mechanics which I can use to argue against Quantum mechanics correctness? So are there any?

How hard is Quantum Mechanics for a non scientists? I'm a Philosophy student and am interested in Quantum Mechanics and its implications in deterministic thinking. I'm thinking of taking a class in Grad School, but if it is going to make my GPA plummet... I'm not mathematical. So I'm worried. I could do particle physics if I wanted to specialize in realism (in philosophy), but it's not of great interest to me. Would particle physics be less mathematic?

Who most impacted the development of quantum mechanics and why? For one of my essays for physics we need to make an argument for which physicists were most influential in the development for quantum mechanics, summarize their contributions and compare them to another contributor, and include the historical relevance of those contributions. I have some physicists in mind: Einstein, Bohr, Schrodinger, and Planck. Any others or any expansions on those given?

How does the many-worlds interpretation of quantum mechanics treat radioactive decay? Examples of Everett's many-worlds theory of quantum mechanics invariably give an example of a one-time measurement, rather than a continuous process like detecting radioactive decay with a geiger counter. The theory would seem to say that at every moment there is a division into a decay world and a non-decay world, which would lead to an infinity of worlds in every time period, however short, and offer no way to deal with half-life and the probability of decay. (Probability seems like a problem with the theory even in the ordinary measurement case.)

So then, if someone could give me a series of websites to study in order to learn quantum mechanics, that would be great.

Does quantum mechanics mean humans really have free will? If particle movement can't be predicted, then you can't predict the future, Newton thought if you knew the position and velocity of every particle in the universe, then you could predict the future, meaning we don't have free will, but does quantum mechanics mean we do?

Keep in mind that, I already know the answer to this question in rigorous detail and I'm only asking because i want to see how little you know about it.

This thought came to me after thinking about free will and quantum mechanics? Even if quantum mechanics is true I can see no way that anything on a quantum scale can effect anything on a larger scale than it self. Quantum mechanics does show that thing are not always predictable but only in quantum mechanics, if Quantum Mechanics is the only true random occurrence in the universe, free will is in theory still not possible.

Online Quantum Mechanics sources for a beginner? I am trying to independently learn Quantum Mechanics and I am having a horrible time. I will buy a book soon to aid me, but I would need some good online learning resources. Most I find are too concise and hard to follow. BTW, I just finished Heisenberg's uncertainty principal but I am still looking for DECENT proof. I would like it to be mathematical, but make sure it explains the proofs and stuff with words too.

Is the human brain significantly affected by Quantum Mechanics? Several books are out that say nerve impulses and synaptic connections are subject to quantum effects. These theories tend to advocate "free will" as being part of the human condition, as opposed to "fate" or "determinism". Other books I've read take a dim view of Quantum Mechanics as a brain-function impactor. What say You?

What portion of quantum mechanics would call themselves "Everettian"? I saw the band "Eels" last night, and they showed the BBC documentary recently filmed in which "E", who is basically the band, goes on a trip to discover what his father was really like throughout life and to understand the reportedly ground-breaking parallel universe theory of his father, Hugh Everett. The film implied this is one of the big theories of quantum mechanics right now. Is it, and how many physicists subscribe to it?

Quantum mechanics vs General Relativity : Which one would you pick ? Although I think there are a lot of aspects in General Relativity which are true but I find quantum mechanics more appealing, hence Einstein did not know that the Universe was expanding since the discovery from Edwin Hubble came 13 years after Einstein had published his relativity. Who cares if he didn't like, just because Einstein said something is true, doesn't mean it is.

I'm an ECE student and I was wondering if you all thought it would be worth taking a Quantum Mechanics class on top of all of my ECE classes? Would taking this class help me at all with ECE in the real world, or would it just be overkill since I'm sure to learn the Quantum Mechanics that I need for ECE in my ECE classes? Any suggestions?

The different universes could even have different laws of nature. I'm sometimes told that I'm living in a world of my own... ha.. maybe we all are! Spirituality doesn't just have to mean a belief in a world religion/God.

In the Multiverse interpretation of Quantum Mechanics, are the parralel universes static or dynamic like ours? I read somewhere that the infinity of parralel universes are all static and unchanging, as if just a testament to the possibility of that particular universe, whilst ours is the only universe which is dynamic and changing as it travels down the percieved timeline. Your opinion? PS: If you find the whole multiverse theory total bunk, that's fine, it's just I'm not really looking for your opinion here. Thanks.

If the electron in a hydrogen atom obeyed classical mechanics instead of quantum mechanics? Would it emit a continuous spectrum or a line spectrum? Explain.

What do you think of the new theories in quantum mechanics today? I've just read Stephen Hawking's book "The Universe in a Nutshell" and Michio Kaku's book "Parallel Worlds." They both posit an 11-dimensional universe with the possibility of parallel universes. I'm not sure I understand it all, but I find it fascinating to contemplate that there may exist other universes with other me's in it doing other things and living other lives. Actually, they are hypotheses not theories. Again, there's the confusion of the definition of the word "theory." An hypothesis is conceived; experiments are performed and tested; a theory is developed. Theory, in scientific terms, does not mean a guess; it's an explanation.
