Interpretation Definition and 803 Threads

While trying to wrap my head around the Transactional Interpretation, I wondered why we need signals from the future. For the electron about to be ejected, the surrounding space is already filled with information about everything around, and if the momentum conditions assign it to strike beyond...

Dear All, Before I lose the link I'll post it up: http://img290.imageshack.us/img290/9122/voltageregulatorlh7.jpg" Can anyone help me identify the unknown component in this picture drawn in blue? I'm trying to come up with an interpretation and circuit diagram of this circuit. It's a...

An interesting question was posed, and since I have many problems of this type I'll just make the question general: Suppose you have operations A and B, if [A, B] != 0, then what can you conclude about a simultaneous measurement of A and B? For example, if A was momentum in the x direction's...

This is not a homework question but one that is part of the course material and I can't really move on until I understand the basic calculus. I have a problem interpreting "d by dx of partial dF by dy' equals partial d by dy' of dF by dx" in the following question, which I set out and then...

Matrix multiplication is clearly defined but is there a tangible or physical interpretation for it? Or is it just abstract formalism? I am thinking about each column of the matrix as vectors so matrix multiplication with two 2by2 matrices is about multiplying 4 vectors in a certain way. The...

I recently learned about the Many Worlds Interpretation of quantum mechanics from another post on this forum. Unfortunately, the post became more of an argument about whether some experiment had or hadn't proven this interpretation to be true, and there wasn't a whole lot of information on what...

Hi, recently, I have read the paper of Marchildon, http://arxiv.org/abs/quant-ph/0405126" . This encourage me to finally read the Rovelli's paper, but I don't understand what really is the relationnal interpretation. I stopped in the beginning of the paper, and I can't continue until I...

Is it justified to state that GR is "just" a geometrical theory to calculate the paths of objects in spacetime? Just because GR states that "gravity is a property of spacetime itself" doesn't necessary mean that spacetime is curved; just that the paths of objects in spacetime are curved in a...

From 0 to 4. ( I don't know how to make the s sign.) squareroot of (16-x^2) I set it equal to y and squared it to get. y^2 = 16 - x^2 Then I changed it to: Y^2 + X^2 = 16 I know it's a semi circle on the x-axis at 0 to 4. What should my final answer be?

I found a website that says: "The still-dominant "Copenhagen interpretation" of Quantum Theory developed by Niels Bohr, Werner Heisenberg, Wolfgang Pauli, and others says two basic things: 1. Reality is identical with the totality of observed phenomena (which means reality does not exist...

OK, I have a problem with the many-world interpretation, namely the quantum suicide experiment. My problem: How exactly does your consciousness transfer over? When you die in your current "reality," do you just swap randomly to one of the parallel worlds? Or are each of the conscious entities...

Does anyone have any opinions on the transactional interpretation of Quantum Mechanics? Does anyone really take it seriously. I know criticisms have been levied against it (to do with causal loops) but others have proposed resolutions to this problem without compromising the overall integrety...

the term "Marseille" is used humorously in part, it could also be called the "Haifa Interpretation" because Asher Peres contributed and he was at the Technion and also David Mermin at Cornell (Ithaca, NY) has written similar stories about how to interpret QM and has called his stories the...

I would like to start a thread dedicated to discussing my explanations and interpretation of quantum mechanics. They can be found at http://thisquantumworld.com" . Your questions and comments (critical or otherwise) will be appreciated.

Hello all, I would like to learn more about the formalism of the transactional interpretation in QM. Apparently, the formalism is NOT the same as in unitary QM (but the claim is that the empirical predictions are equivalent). As such, it is not so much an *interpretation* but an equivalent...

GEOMETRICAL STUDY OF SCHROEDINGER'S FORMULA If we take a look on previous expression, we could continue with the importance of complex numbers. The complex numbers are very important to represent points or vectors in plane, and can be expressed this way: a = b·x+c·y If we choose...

Which carries a greater weight regarding the outcome of communication? E. g., if I encourage an individual to go out with me, and they respond according to their personal judgment, whose action would be more influential in the general milieu?

to preserve commutation relations in the quantized field operators (basically simple harmonic oscillator raising/lowering operators), a vacuum mode must be introduced in the case of a usual 50-50 beam splitter. thus, one has 4 modes: vacuum incident mode reflected mode transmited...

The other day, I (once again) decided that I simply don't understand natural transformations. (Or functor valued functors, for that matter... which greatly disturbs me because I'm usually quite comfortable with function valued functions) So, I sat down to try and figure them out, and I...

Please let me know if this is the wrong place to post this question. I'm really fascinated by the idea of time symmetry in quantum mechanics and it's implications for the measurement process. I'm trying to make sense out of an article posted in the arXiv by Aharanov, et al. and it seems like...

About a week back I posted in the strings forum asking about how current theories interpret gravitation and how they differ from general relativity. But the main subject of the thread wasn't how physical theories should be interpreted, so I'd like to pose that question again, in greater detail...

Can someone please help me out with the following question? Q. A simple harmonic oscillator, of mass m and natural frequency w_0, experiences an oscillating driving force f(t) = macos(wt). Therefore its equation of motion is: \frac{{d^2 x}}{{dt^2 }} + \omega _0 ^2 x = a\cos \left( {\omega...

I stumbled across this site quite by accident. I've never heard of the Perimeter Institute for Theoretical Physics, but they know how to party! Earlier this year they hosted a series of lectures on "Interpretation of Quantum Mechanics: Current Status and Future Directions". A top-notch...

I don't know where I can post my question that will certainly appear to be a kind of heresy or the proof of my naivity. We all have learned the duality between wave and associated particle (or the way around). Some particles are carrying an electric charge. This means in reality that if the...

http://arxiv.org/ftp/gr-qc/papers/0506/0506007.pdf Title: A New Interpretation about the Evolution of the Cosmos Authors: Fang-Pei Chen Comments: 16 pages Based on Lorentz and Levi-Civita's conservation laws, it can be shown that the energy of the matter field in the universe might...

In order to quell complaints from those members of the board who feel they are being discriminated against in my recent threads, I would like to directly address the issue of a non-cosmological interpretation of redshift. If you're a layman trying to learn about astronomy, I advise you to...

Dear Friends, Does anybodi knows the meaning, or anything related to the term: \Psi \nabla \Psi^* or \Psi \nabla \Psi^* - \Psi^* \nabla \Psi Is the representation of something in the reality? Best reggards.

It appears more and more people are challenging the traditional interpretation of the Compton/Photoelectric Effects. Cramer back in 1986 used the Hanbury-Brown-Twiss effect to show that there is not a 1:1 correspondence between the emitted and dected quanta. You have to combine fractions of...

I wasn't sure where to put this thread because it is about moral philosophy but depends on your understanding of quantum mechanics. I'll try to keep quantum mechanics out of it and just explain what results from the Many Worlds Interpretation (MWI) of what's happening in quantum mechanics (QM)...

I am not completely satisfied with Griffith's explanation for the geometrical interpretation of a gradient. Can someone elaborate on the geometrical meaning of the magnitude and the direction of a gradient?

Being a Kubrick fan, I just had to pass this along knowing that someone here would appreciate this. Enjoy! :biggrin: (flash required) http://www.kubrick2001.com/2001.html

-- -- EPR experiments seem to show a significantly higher correlation rate in the detection of separated photons which are in an entangled state. From the measured correlation we may or may not want to draw very fundamental conclusions. One such a far reaching conclusion would be that...

Special Relativity predicts that moving clocks run slow, mass and length are variable and simultaneity is relative. These are 'real' phenomena and leads me to think that the reality of one observer (the passing of time, all physical properties and space-time events) can be regarded as 'his...

:smile: 1.Can anyone explain the physical interpretation of the Quantum numbers? 2. How they are vectors? 3.Are they known before solving the hydrogen atom problem? 4. Are there quantum numbers for protons and neutrons also?

I was learning about the "Many Worlds" interpretation of QM, and it got me to thinking. In some ways, doesn't it contradict the laws of thermodynamics? I came up with the following thought experiment: Suppose that you had a gas containing nitrogen and oxygen in a homogeneous mixture, in a...

so I herd that atpms are actuall blob like particles insted of hard crystal orb like things but are quarks the same way? are quarks like blobs too?

I have a fundamental question regarding the uncertainty principle (position and momentum). This principle states that it is impossible simultaneously to know both position and momentum with arbitrarily good precision - even in principle. Now, what does "know" mean? No one can prevent you from...

When I use d, I am referring to a partial derivative here. So where w(z)=u(x,y) + iv(x,y), and the derivative of w(z) exists, I have shown that (du/dx)(du/dy) + (dv/dx)(dv/dy) = 0 But I have to give a geometric interpretation of this which is somewhat confusing to me. I am not sure what...

Hi, I would like to know what is the physical interpretation of magnetic reluctance. Also, I would like to know why should the magnetic flux in a magnetic circuit composed of different magnetic materials and subject to a magnetomotor force should be the same? Thank you.

After having researched on many different Websites the Many Worlds Interpretation of Quantum Mechanics, it seems to me as if there are two positions defended by physicists: Position 1: All the outcomes of a system actually happen in reality. That is, every time a choice is made all possible...

Hi, I posted this question in Astronomy & Cosmology but by advice of some users I post it here as it has some philosophycal side too: It seems to me that block time is an unavoidable consequence of Relativity. The fact that events that still lie in our future must have already been observed...

hiya! Does anyone know of any logical expressions of the Copenhagen Interpretation. I've read about it, I can summarize it, but I've never really seen anything other than discussions of it in pop-science books. I'd really like to break it down if I could.

It seems to me that block time is an unavoidable consequence of GR. The fact that events that still lie in our future must have already been observed by other (hypotetical) observers seems to leave no room for escaping the fact that (at least some of) the events in our future "have already...

In the transactional interpretation of quantum events, can the absorber and the emiter correspond to the same particle? Could an electron at time t1 for example, transfer a virtual photon to itself at time t2? If this is the case, could this provide an explanation of why an electron does not...

I know the definite integral of a function can be thought of as the area between the function and y=0 and between the lower and upper bounds of integration, so long as the function is positive in that region. However, I also know that: \int_{a}^{b} f(x) ~dx = -\int_{b}^{a} f(x) ~dx And...

Hi What is the physical interpretation of Feynman path integral? Thanks :smile:

(3p^2 q)^3 \div 9 p q^2 The above is a simple algebra expression. The question concerns the correct interpretation of the divisor in the above example. Strictly speaking I would have thought that only “9” is the divisor here and if you wanted the whole “9pq^2” as the divisor then you should...
