Interpretation Definition and 835 Threads

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...

recently,i am having a report on the issue concerning the quantum interpretation,somehow,i choosed to read the transactional interpretation by prof cramer.i have complete about 60% of the studying,however,the deadline is coming closer(march 13th).as a result,the alternatives interpretations...

Just wondering if you all believe if the bible should be interpreted as symbolic or literal...
