Interpretation Definition and 803 Threads

My understanding of this interpretation is that (in the context of the electron double slit experiment) the experiment is one particular outcome of an ensemble of equally prepared experiments. This explains the statistical nature of QM. But how does this explain the interference pattern...

I came across this document http://www.hedweb.com/manworld.htm#faq containing a plain english explanation of the Everett interpretation. While it is clear that the author is very much in favor of this interpretation and has objections to others, is there any thing here that is fundamentally...

Would anyone have any resources on the stochastic interpretation of quantum mechanics? It appears to be a relatively new interpretation, proposed this year by Roumen Teskov, based on John Wheeler's "quantum foam." That's really the extent of the information I have, and I'm curious to find...

Homework Statement Calculate the photon energy threshold for the reaction γ + p → p + π. Assume that the initial state proton is stationary. <thats really it> Homework Equations < unknown, but suspects include: standard special relativity equations > -- other useful relations: proton rest...

Homework Statement Prove the points of the open interval (a,b) are those of the form a + t(b-a) for 0 < t < 1. Homework Equations The Attempt at a Solution I'm interpreting this as asking me to prove that if x is in (a,b), then x can be written as a + t(b-a) for some 0 < t <...

Homework Statement The probability mass function of a random variable X is: P(X=k) = (r+k-1 C r-1)pr(1-p)k Give an interpretation of X. Homework Equations The Attempt at a Solution The PMF looks like the setup for a binomial random variable. The first combination looks like you...

Homework Statement Let F_4 = {0,1,a,b} be a field containing four elements. Assume that 1 + 1 = 0. Prove that b = a^{-1} = a^2 = a + 1 . Homework Equations The Attempt at a Solution Do I assume that 0, 1, a, and b are al distinct elements? If so, then I can prove the question.

Suppose A box represents the universe. It also has a battery and a propellor inside it. The propellor is supposed to increase the temperature of the whole universe including itself and the battery. If this hypothetical universe is initially at 25 degrees C, then we incresed this temp to 27...

Homework Statement If you step on your car's brakes hard, the wheels stop turning (i.e., the wheels "lock") after 2.0 revolution. Part A. At the same constant acceleration, how many revolutions do the wheels make before stopping if your initial speed is twice as high? Homework...

Question concerns the existence of the interaction in boost operator in the instant form of relativistic dynamics. (referring to "Relativistic quantum dynamics" after E.V.Stefanovich, http://arxiv.org/abs/physics/0504062) From the existence of interactions in boosts (e.g., in instant form...

In another thread a discussion arose about the interpretation of derivatives. For example acceleration is the time derivative of velocity. Obviously, in the strictly mathematical sense: in relativistic physics and classical physics alike acceleration is the time derivative of velocity...

These questions were originally asked to one of PF.com's member, but he wanted me to post it publically so more people could benefit from the answers: Also if anyone else got enough knowledge about this interpretation to answer these too, go ahead. #1 In dBB (deBroglieBohm), what does...

Many physicists say that they prefer the "Copenhagen" interpretation of QM, but it does not mean that all these physicists prefer the same (or even a very similar) interpretation. There are at least 4 very different interpretations that are sometimes referred to as "Copenhagen": 1. Shut up...

Here I try to explain what I read somewhere- that the speed of light has decreased over the last couple of centuries. If it is reported that the speed of sound is decreasing in a solid, you may say thatdue to continued vibrations and deformations of the solid, its modulus of elasticity has...

Can the circulation about some closed (rigid) path in a force field be interpreted as the work done by the force field on the path over an infinitesimal time?

Hi! I am trying to find out where: cos\theta=\frac{a \cdot b}{|a||b|} came from. Here is mine geometrical interpretation of scalar projection: Now, (pr means projection) pr_{\overrightarrow{A}} \overrightarrow{B} = p\overrightarrow{B_0} and...

Karl Popper, the highly influential philosopher of science was unusual in that, as a philosopher, he had a large impact on science itself. He was actually listened to by physicists! He's best known, of course, for his falsifiability criterion for theories to be considered scientific, which has...

I have started to read about Rovelli's Relational interpretation in Wikipedia. http://en.wikipedia.org/wiki/Relational_quantum_mechanics#All_systems_are_quantum_systems In the section labeled "All systems are Quantum Systems" in the article it says: In the above paragraph it is assumed...

In the Schwarzschild Metric, the curvature of space around the gravitating mass can be described by the Flamm Paraboloid: w(r) = 2 \sqrt{r_{s} (r - r_{s})} Unlike the Newtonian depiction of Gravitational Potential Wells (U = - G M / r) which decrease inwards, the Flamm Paraboloid increases...

I am running (a very basic) simulation of the proposed LIFE concept reactor at LLNL as part of my MSc thesis. What I hope to achieve is to calculate the fission energy gain from a fissile blanket surrounding a source of fusion neutrons (ie D-T pellet blasted by lasers) The problem summary...

Does mass warp time because there is no time contained within the mass itself? (making a gradient like hot flows to cold sort of thing, except its time flowing to mass) My assumption is that gravity is the measurement of the warping of time, and as you get closer to the mass, gravity is...

If we have an operator A which operates on some state described by vector x the result is a new vector y A |x> = |y> My question is: is the new vector y considered to be a different state vector in the same vector space as x or is it considered to be a vector in an entirely different vector...

the idea is is there a Linear operator L so L | \phi _n > =p_n |\phi_n > with p_n being the nth prime and L a linear operator , is it possible to have an spectral interpretation for prime numbers ?

Is this interpretation on "Hubble's Law/Constant" right ? I referred to this page http://en.wikipedia.org/wiki/Hubble's_law The hubbles constant 'H0' is anywhere between 72 to 78 kms per second per megaparsec. My doubts :- 1) Let us consider a rod (made of streatchable light weight...

The ensemble interpretation of QM essentially ignores the wave function collapse, and apparently decoherence as well, by stating that only the statistical distributions within ensembles of systems matter (each system being in just one state). My questions are: Does the preparation of...

hi guys , I want to ask every intellectual persons , a question? A newly born baby which just got from mothers stomach,what is in its concept that makes it weep(please psychological interpretation)

Hi everyone, I need to make sure that I'm interpreting the Shapiro WIlk test correctly. This is how I'm doing the interpretations: Set 1 CI = 95% n = 15 Shapiro W = .92 p = .171 I think this set is distributed normally because p is the probability that it is not normal, so the...

Hello all I have been at ease with spacetime diagrams of the usual sort where the y and z dimensions are suppressed until I came across this passage from the following book. Problems of Space and Time. A reader edited and with an introduction by J.J.C.Smart. Page 293 of the chapter...

I started this thread to continue the following discussion from the thread: https://www.physicsforums.com/showthread.php?p=2203566#post2203566" But you and Weinberg are both making a mistake in assuming ontological status to both the collapse of the wave function and to entanglement...

How do you interpret this?

I am interested to see a clear enumeration of the postulates of this interpretation. There seem to be something fuzzy about how MWI describes what we call "reality". It might be a problem with the theory or, more probable, a misunderstanding of my part. Here is a list I found on Google...

Hi, I've just finished a 2 semester course on Quantum Mechanics and I am now eager to learn some Quantum Field Theory. I started to read some books on my own, but I have some problems understanding a few concepts. My main problem is this: In the Canonical Quantization procedure, we take...

(My previous thread on Bohm Interpretation quickly became 4 pages of mostly unrelated discussion. So I'm restarting here with more precise questions.) Okay, I've read some references on the Bohm Interpretation and I am still confused. As one paper mentioned, some extensions have stochastic...

I do not understand why (apparrently) so many people on this board prefer the Bohm interpretation. To have more meaningful discussion, I tried to refresh my memory on the details and read some about it. Unfortunately, Bell's "unspeakable in quantum mechanics" book was not very helpful to me...

Hi, Can u point out physical interpretation of the complex permittivity? (ie. what can u expect from a material with \epsilon' = x and \epsilon'' = y ? what happens if y is very large etc. \epsilon = \epsilon' -j \epsilon'' thanks Krindik

Hi, I'm trying to remind myself of exactly what, physically, is the difference between V and A couplings. Now, a vector coupling is of the form \bar{\psi}\gamma^\mu\psi, and axial coupling of the form \bar{\psi}\gamma^\mu\gamma^5\psi. Thinking in terms of a chiral fermion expanded as: f...

I'd appreciate any explanations of the physical interpretations of Einstein's stress energy tensor...for general relativity...maybe a favorite explanatory/expository online source. Wikipedia is not very satisfying on this nor on the electromagnetic stress energy tensor. For example all involve...

I recently read about the pilot wave theory and the Bohm interpretation, and I must say I really like the idea. The only of my confusions it leaves unchanged are those concerning the EPR paradox. The Bohm interpretation does not seem to answer the question of the dreaded spokhafte Fernwirkung...

Homework Statement Hello :smile: The question is from "Advanced Physics" by Adams and Allday. It is from section 9 "The Physics of Particles", "Practice Exam Questions". It is question 11, part c. The level of this study is between school and University. Figure 9.5 represents a simple...

How to make another interpretation of "curl"? Recently,I've tried hard to find the physical interpretation of "curl". But , most of what I found were the same ,that is,"fluid flow"! I'm now wondering whether there's another annotation so that I can learn more about vecor calculus...

Since C_0^\infty (the space of smooth functions with compact support) is reflexive, we should, in theory, be able to identify every distribution (object that lives in the dual space C_0^{\infty '}) with a corresponding actual function in C_0^\infty. Is it all interesting or useful to do so...

According to the Many Worlds Interpretation the universe supposedly splits off into two realities when a quantum event has more than one possible outcome(Schrodinger's cat for example). One in which Schrodinger will find his cat dead, and another in which his cat lives. But what happens for the...

Hi everybody! I'm trying to find the probability at time t of finding the state pointing in the positive x-direction of an initial system which points in the negative x-direction. I'm not sure if the result is correct, but I get [SIZE="4"]the probability is sin^2(iwt). Can this be understood...

What is it that motivated Max Born to interpret psi in Schrodinger's equation as a probability amplitude? It seems a very strange thing to do - first of all what made him think that the elementary properties of particles should be of a statistical nature, and second why did he interpret it as a...

Hi, I am currently studying the application of Gauss Seidel iterative method for solving systems of linear equations and am having trouble understanding the principle behind it. Can some1 provide any graphical or intuitive interpretation?? thank you

Hi Is it possible that same wavefuction described by math can be interpreted to different aspect? For instance, Some wrote wave function as same as momentum eigenstate which is normalized But he seemed claim that it is not momentum eigenstate even mathmetical formula is same...

Homework Statement a particle moving in one dimension between rigid walls separated by a distance L has the wave function \Psi(x)=Asin(\Pix/L), since the particle must remain between the walls, what must be the value of A? Homework Equations The Attempt at a Solution Ok so I'm...

Hello, I've really been enjoying reading these forums the last couple of weeks, and finally decided to register to ask a question. This is an earnest question about what the modern interpretation is, and how I and another student of relativity can learn more about the modern understanding...

Folks, I'm in the process of trying to understand spacetime curvature in general relativity. My question might sound odd, but I'm wondering how to best conceptualize spacetime distortions due to a moving mass. If there is a large mass, e.g. a planet, moving through spacetime, the curvature...

We can estimate the value of Δ and B from Tanabe Sugano diagram. For example Ni2+ which is has the electronic configuration of d8. So, by referring the d8 Tanabe Sugano diagram, we can can noticed that there are 3 types of transition. The transitions are observed as V1=8500cm-1, V2=13800cm-1...
