Quantum Theory

Hello, I have read many posts where I find the above expression (Most notably from Mordred) but I only encounter it as part of explaining some other topic. Could you please expand on this with more information? It is a really interesting subject for me.

Very often people come to these fora with a belief that our current theories of physics, such as the Standard Model or relativity, are flawed and present some alternative of their own. On the whole, this is a fine attitude to take - we should always be skeptical, and it is good if people can think a little 'out of the box' and generate ideas which more standard thinkers may not have come up with. I have always thought that genius was not an ability to think 'better' than everyone else - it is an ability to think differently from everyone else. However, when coming up with a new theory it is important that it should be better than the old one. Therefore the first step …

Hi im new to the whole idea to quantum physics, and the internet wasn't a very reliable source. It's seems to me u guys know what ur talking about, and I could greatfully use the help.

1+1+1+1+1-1-1-1-1-1 without adding = symbol to it

- pi ratio and + pi ratio?? Question please..Particle Confinement Under fundamental forces here: http://hyperphysics.phy-astr.gsu.edu/hbase/forces/funfor.html#c1 It mentions how these are connected to the "confinement" particle in a box. It shows the "graphical symbol" - pi ratio " this is how it looks between strong forces" on the link above for QM. My question is how is it possible that pi " ratio" is 3d dimensional?????? Is this true? I thought pi ratio was a circumference... If this is truly coupled with The Uncertainty Principle, then "I am guessing here not debating" That pi must have an anti?? Also, how can pi ratio both be used a…

i once heard about a quantum coral, and something like, it was made up of 48 iron atoms,,,,,, i think....... well, im sure of what i just said, but other than that, i dont know anything about it,.. does anyone know anything? more info. would be nice? there was also a picture of it, it looked sooo cool, hard to describe though, like a mix between the surface of a liquid, when something is dropped into it and a coral! [so descriptive] and google search is useless, it comes up with loads of medical stuff, thats not what i saw! HELP..... what is this mystery thing....

Hi all. I'm new in this forum Please,forgive my no very good english Quarks and tachions share the feature of be: ¿Unobserved? ¿unobservable? Could an ultrarelativistic (tachionic) model of quarks to describe some features or behavior of quarks? Why a tachion has negative energy in the context of SR? How could this model be contrasted.? That is :how could it be designed an experimet "falsabilizante"? i Thanks: health, peace and good luck. lanjarote

Hello All, Recenlt I've read mostly about "many -worlds". As I understand, it is still not universally accepted interpretation, but there are some reports that certain experiments simply proved it, like Vaidman- Elitzur bomb test, Zelingher interferometer, vacuum etc, double- slit experiment, that electron seen to be both in 2 places (M.Kaku)... There are also reports that this interpretation was "mathematically" proven... So,I'm confused. Some people claim that these "wordls", if they exist, are by definition beyond human observatiion, other say that that these "worlds" were observed, still others claim that all data indicates these "worlds" can be explaine…

How does 'Squeezed Vacuum' technology aid in the creation of quantum computing networks..................... Merged post follows: Consecutive posts mergedOk...so how does the technology quoted as being called 'Squeezed Vacuum' technology applied in this http://www.sciencedaily.com/releases/2009/02/090203130708.htm help provide a means for quantum computing..................... How could a better vacuum make for better changes in chiral states and create say a quantum comparator?

Hi, I often wonder about "dimensions"? You could say we live in a "3D" world - but in reality, isn't that just a "volume"? Does it even make any "realistic" sense to talk about anything less than "3D", or anything more? Theoretical physicists & mathematicians talk about "zero-dimensional points", but something without any "size" cannot even be said to be a "thing", surely? Likewise for a "one-dimensional" line, or a "two-dimensional" plane - there is no "breadth", so it can't really exist outside of a mathematician's imagination? Likewise for higher dimensions, say 5, or 11, etc - isn't this nonsensical? Is discussion of "dimensions" simply playful mathematics? In rea…

i.e., the hypothetical "particle responsible for gravity." Beyond the fact that everything else seems to be particles/waves, is there any reason to expect that such a thing exists? Given the ridiculously small effect/probability of such a thing, do we ever expect to actually detect such a thing? Wouldn't its effect fall within the range of quantum uncertainty? If we can't ever detect one, is there any point in talking about them? Further, if it is impossible to detect one, shouldn't we be saying that it doesn't exist? Talk down to me. I'm way out of my league with this stuff.

Hello everyone I am new here I would like to know how to calculate the h constant at home... It is hard to understand, base log 10 systems.. It is this base log system of 10, that is really hindering me to move forward. It is also Newtonian Mechanics, that is " confusing me " with photon energy and light "speeds".. Then you have the fractions to deal with. However, Distance and Frequencies is my main focus... Until I know this I refuse to move forward with anything else..

Taken alone I understand each of these words... I am at a loss as to spin and why it is referred to as intrinsic angular momentum, it is not motion, not torque, not spin... Obviously it is intrinsic... Please help, I have been reading all kinds of texts and I still just don't get it.

Hello, everyone! What do you guys think about these 2 topics of the universe being a giant hologram and the James Gates math equation found suggesting that we live in a simulation. Here are the links: The hologram article: https://www.rt.com/news/space-evidence-universe-hologram-195/ Youtube video of James Gates's math (simulation) equation: Basically, my questions are: Can you guys explain these 2 topics more and what do they really suggest? Are they strong enough evidence to prove that we live in a simulation? My other question is: With these 2 links/ topics, what are the other possibilities of these math equations and findings besides us being in a…

http://www.google.co...ved=0CBkQ9QEwAQ This simple shading illusion reminds us of our limited ability to accuratly process what we see. Q: Could entanglement be one of those evolutionary adapatations? The double split expirement certianly suggest that simply observing the photons changes thier pattern but I wonder if that is just a rationality of our limited comprehension? A: ??? Someone shed a little light. (or at least what my limited concepts can process as light)

In this week's NewScientist (3rd Nov.) There is an article titled "quantum untanglement", by one Mark Buchanan. (not, I believe the same person who comes up as a Baptist minister!). He appears to be a phd and sometime editor of this magazine and Nature. I can provide no links, because it requires a subscription which I do not have. The reason I hesitantly bring this up, is that my knowledge of the way things are, and the way they might be in the future, is through such "popular Science" articles. They feed my curiousity and fuel my imagination in an easy to assimilate maths-lite way. (As of course do also many of the threads in this august forum;) ). I hope th…

Please ponder the SWE, for the Hydrogen atom: [math]E \Psi \; = \; \hat{K} \Psi \; + \; V \Psi[/math] where [math]\hat{K} \propto - \nabla^2[/math] is the 'QM KE', or 'Q-KE', operator. Now, the energy [math]E[/math] is a constant. But, the potential energy [math]V[/math] varies through space, being "very negative" near the nucleus, and "nearly zero" far from it. Thus, this leads to two regions, of the Schrodinger solutions, for the Hydrogen wave-functions: Classically-allowed region (r < rBohr,n) -- Q-KE is positive; wave-function is 'concave down'; "body" Classically-forbidden region (r > rBohr,n) -- Q-KE is negative; wave-function is 'concave …

"Physicist Fotini Markopoulou Kalamara has developed a way to connect relativity with quantum theory--while making sure that cause still precedes effect" Basically they're developing an alternative to string theory. They call it "Loop Quantum Gravity". "In LQG, reality is built of loops that interact and combine to form so-called spin networks--first envisioned by Roger Penrose in 1960s." "Each spin netowrk resembles a snapshot, a frozen moment in the universe. Off paper, the spin networks evolve and change based on simple mathematical rules and become bigger and more complex,l eventually developing into the large-scale space we inhabit." I'm not sure how…

Seems like a great time to try something.

From what i understand particles just like light can also be represented as waves. But since you can combine electromagnetic waves ( eg light) to make a differnt wave pattern, which basicly means they exist on top of each other. Can particles ei electrons, do the same? Meaning co-exist in exactly the same place.

Hi, I'm currently doing a PhD and I've done a short video to explain it to my non-physicists familly and friends. It's about carbon nanotubes and how to use them to produce single photons. Here it is : link removed by mod Hope you enjoy it

Although I'm pretty sure there's another equation for this which I can't remember, I noticed that in an energy level of say, 1, or the ground state, the wave of a single electron has 1 crest, and one troff, or two vertices total, and the amount of electrons that are allowed in that energy state is 2. Then I go to the second energy state, the wave of a single electron with its maximums and minimums has 4 vertices, and the energy level is 2, and 8 electrons are allowed. At the third energy level, there are 6 maximum and minimum vertices, and the energy is 3, and there are 18 electrons allowed in that state. It would appear as though the amount of electrons allowed in a sing…
