Quantum Theory

I read this very often in science fiction. In Ilium the Quantum Matrix around Achilles was changed. In The Dreaming Void Advanced Neural Systems is embedded into the Quantum Lattice around earth. In The Night's Dawn trilogy there is something that can control Vacuum Fluctuations (aka Quantum Fluctuations according to wiki). Now Quantum Physics tend to be used to explain all sorts of funky technology in science fiction but I want to know just how much is really based on actual science. What exactly is a Quantum Matrix/Lattice? If I understand it correctly, Quantum/Vacuum Fluctations, Space-Time/Quantum Foam and the Casimir effect are all closely related. It'…

Does anyone know whether there are currently any interpretations of quantum mechanics that are entirely deterministic? I was recently watching a debate between the cosmologist Sean Carroll and the Christian apologist William Lane Craig, wherein Craig claimed that there exist interpretations of quantum mechanics that are entirely deterministic. Now, frankly I would be tempted to just dismiss the assertion outright as an ad hoc attempt at rescuing his first premise from being falsified, because I've certainly never heard of such an interpretation if it exists, but I could be mistaken. My understanding is that even the most deterministic interpretation I'm aware of that …

.1 as I understand, one particle can be in two places at the same time. for instance tha particle that is building the table can be in the table and in the same time sumewere els. my question is are we talking about two particles or about one. if we are talking about one particle, what makes the table exist at the time the particle is sumewere els? . 2what makes the string vibrate according to the string theory? )I'm apologizing for my poor English( simon

Need help w a question. a question about something I recently saw on cosmos.

Good day. Will be the following geometry to generate negative energy?

And so on 200 * . . . V

In Wikipedia "Double slit" the principle of complementarily is defined as "that photons can behave as either particles or waves, but not both at the same time", stating that an interference pattern disappears when the path of the particle is known. But with a single slit you know the path and still the photon diffracts, which is a wave effect. So how is complementarity exactly defined in this case ?

It's often science documentaries that give me new ideas or offer information on existing ones. Same with an awesome series about spacetime, which recently mentioned something I didn't know about although it didn't elaborate much on. Best idea felt to ask. From what I knew, the leap of an electron into different orbits happens at a constant or random rate. In other words, no interference (at least known to people) typically triggers an electron to "appear" in another location... it just happens based on probability. I did hear that "electrons borrow energy from their surroundings and give it back later", but that still means no known event triggers the leap itself. …

I have studied QM for about 2 years now " on the extreme technical side", and am now realizing that many consider QM, as some type of virtual hyper reality in where consciousness " can change " things" for example: Does consciousness really collapse the wave function? Or can simple positive thoughts promote good health, a stress free life and make you just simply feel good? Or maybe QM is just that mind boggling to understand?????? QM seems to describe a digital realm of subjects that almost seems to never end! Terminologies after terminologies just lead to more and more questions not answers. But, doesn't QM deal with: atomic orbitals that …

I have a doubt/question/idea what ever it may be some thing like this Theoretically is it possible if we place one of twin electrons(Quantum entanglement)into event horizon of Black hole and observe the second one on earth, so that what is happening in Black holes? i.e how electron's inside event horizon have physical properties such as position, momentum, spin, polarisation, etc are correlated with first one on earth?

Hello. My name is Joe. I consider it an honor as well as a privilege to be able to talk and communicate here with so many minds that are interested in Science. I am not a scientist myself, and currently do not have any degree, scientific or otherwise. I hope that that is not a problem with my being on this forum. I enjoy theoretical Psychics. I also enjoy complexity science, cybernetics, and AI theory, as well as the theory of reflexology. From my personal experience, I have learned that even though it is hard to get even 8 or 9 scientists to agree on what complexity is, we usually still get back the word complexity. 100 years ago people use to die in bed, with everyone …

I cannot find my past posts on this topic in the Quantum Physics forum. I fully anticipated on my very first post on this topic, that my posts would be moved into the Speculations form. I have searched the Speculations forum, and cannot find my past posts anywhere. Perhaps I have simply missed seeing something, but I looked fairly well in these forums, and for significant times in the past, and I do not see my posts describing this geometric revolution in atomic modeling. Perhaps the quantum physicists list managers reading my work, who are undoubtedly "hard core" QM physicists, are afraid. The physical truth is deterministic chaos, not white noise QM. This probably intui…

I have read in places that this is not outside the realm of possibilities but the details are pretty vague, can anyone elaborate if this would be similar to normal 2 particle quantum entanglement? what i mean is, with 2 particel QE and enough computing power wtc we know it is possible to "teleport" the information i contain to another predetermined location, would this work with 3-way+ QE? for instance, in this case would there now be 2 of me that are recreated, essentially giving me a "Quantum Twin"? the reason i ask is not because i want there to be 2 of me, but rather, if this is correct, it could essentially eliminate world hunger and any such resource def…

I've recently been interested in understanding physics and how the universe works. About a month ago, I've gotten to a conclusion which I believe might explain the basis of quantum mechanics. Fot those interested to read about it, see this thread (warning, huge post, but IMO worth looking at if you have the time and energy). Although it's a hypothesis I strongly believe in (because it makes sense in every logical aspect), it's highly incomplete and has no mathematics behind it, as others have pointed out. For this reason, I'm trying to understand a few details about quantum physics, which might help make more sense of how this works. They're the sort of thing I tend to ha…

I've been watching videos about quantum foam, multiverses, and string theory. One of the things that gets me is that if universes can come together and combine, and if there are infinite universes, then why am I not seeing obscure things each day that break the laws of physics and seem out of the ordinary, such as people walking around with antenna on their heads? Then I start to question if infinite multiverses are combining and leaving at an instantaneous rate, then the universe we currently reside in is the most stable configuration that can occur. Has there been any speculation in relation to the quantum foam theory or multiverse theory as to why this universe app…

What is it?

Traditional quantum mechanics seems to come up short in respect to predicting chemical reactions and looking at the forces and motions of atoms and molecules. We need a way to reconcile physics and chemistry.

First time poster, I don't have a scientific background but I understand enough of the theory to be curious about some of the assumptions made in the dual hole experiment. If you will allow my layman's brain to try and present them to you without revealing too much of my ignorance. I have some ideas and I would like a sounding board if that would be OK. If not please delete // move this post. While watching an animated illustration of the dual slit experiment, and watching as the two narrow lines became an interference pattern, the narrator assumed the particles acted like waves, and could prove it to some extent with another illustration. This is the accepted scienti…

To find the speed of light they had to use the measurement of the 'metre' that was not defined by the speed of light, so how can they define the new concept of the 'metre' based on the speed of light if the old 'metre' was measure with the old concept of the metre?

Hello! On wiki page http://en.wikipedia.org/wiki/Isotopes_of_carbon we can read that decay energy of Carbon-11 isotope is 11C -> 11B + e+ + Ve + 0.96 MeV The first one with 0.96 MeV is correct. I am receiving exactly the same value. 11C + e- -> 11B + Ve + 3.17 MeV But this one, I am not so sure whether it's correct. Can someone point me to other sources mentioning this decay energy of Carbon-11 to verify data.. ? The best would be couple independent sources. After posting I found this http://www.nucleide.org/DDEP_WG/Nuclides/C-11_tables.pdf which mentions 1.982 MeV as decay energy of Carbon-11 (decay through electron capture). And that was …

I do not know if this is even viable, but it struck me at least of a cool sci-fi based sensor technology. I detailed everything on reddit here: http://redd.it/1xum5v I will paste a copy of what I typed below: I know pretty much nothing about quantum physics and I do not pretend to be knowledgeable about it, I am just curious about the viability of this. What do you think?

So, as I understand it, virtual particles can exist because they exist for such a short period of time, so as uncertainty in time decreases, uncertainty in energy increases, creating enough energy for a particle to exist for that time increment. But why does uncertainty in time decrease as the length of time decreases? Is uncertainty equal to change? Is that why uncertainty and change are both represented by delta? I'm very uncertain about what uncertainty actually is.

Hello. I'm not sure I'm posting in the right forums, please excuse me in case. I may also be saying something very silly, my math is not that bad but it's quite below what is needed to grab quantum theory, so please excuse me again in case. This is a form of Schrödinger's equation: i * dΨ/dt = H * Ψ In my understanding the imaginary 'i' is what allows a first-order differential equation to have periodic, 'wave' solutions, while the same equation with strictly real coefficients only admits decaying exponentials as solutions (as it happens in the 'real' world, for instance with the charging at constant voltage of an electric capacitor). What about writing S…

Well the last days i was trying to comprehend what is going on with the spectacular phenomenon of superfluidity. I saw some experiments with helium cooled to the temperature of 2.17K. I read about zero viscosity and all these exciting abilities it has but i couldnt find how helium acquires zero viscosity. In addition i read that it has something to do with bosons and the Bose-Einstein Condensation and if yes what exactly is that? I would appreciate it if anyone could explain me some basics things beacuse i am really interested in this phenomenon and quantum physics generally. Thank you for your time and sorry for and mistakes regarding my english as i am 16 years …

Example: Photons are entangled, so when measuring polarization of one of the photons (yielding a random result) the other photon will show a perfectly correlated polarization, even if both measuring events happen at a timelike interval. However, for photons no time is passing, time and distances are shrinking to zero. For them, everything is happening simultaneously. I wonder if this may be considered as a local and realistic explanation of quantum teleportation (for photons).
