Ok, that makes sense. It does give me the impression that even as a metaphysical concept, the idea could get into problems when tracing out the consequences. If I manage to substantiate a reasonable system, I'll return to this thread, but if not you can expect this thread to die a slow death...

I only studied basis quantum physics as a graduate, my main focus was on light technology and I didn't carry it much further from there. But the passion for understanding how the world works remains. Basically, I was wondering what would happen if one were to explain quantum phenomena not so...

I like to hear some more about how this is done. Do you have good references? I'm currently working on a kind of Recurrent Neural Networks which would be able to predict time delay between pulses, and hopefully, also time jitter? I know nothing about jitter, but my idea is: if I can tell you...

Homework Statement I'm using http://ece-www.colorado.edu/~bart/book/" to understand my course on semiconductor physics better. In paragraph 2.3.4, the difference between insulators, semiconductors, metals is explained, based on the differences in bands. I understand the basic model. What I...

Right. I'm not so sure how I'm supposed to imagine this 'gravitating potential'. Does a 'heavier' particle like the neutron (compared to the neutron) invoke a stronger gravitating potential? And how does this influence the carrying vacuum?

For years, I've taken the Pauli principle for granted, but now that I've taken a course on Subatomic Physics, I'm mystified again. The example is given in the course of Neutron Stars. Neutron stars are burning stars that experience an incredible compression, drawing a lot of matter in a very...

I was wondering whether it is possible to use photochromatic switching effects, for photonic structures on silicon. The problem might be that silicon is not transparent for the same wavelengths as photochromic materials. So basically, I was wondering if somebody knew about applications...

Hey, thank you very much for your reply! Do you have any reference that describe some of the stuff you said? I would be very interested in reading some papers that discuss the condensed phase interactions you mentioned.

Molecules are optically active when they react differently to left or right circularly polarized light. This is because they have a screw-oriented structure which is itself either left-handed or right-handed, making propagation preferential for one polarisation, rather than for the other...

I only have applied courses of quantum physics, so in my textbook fundamentals are only briefly mentioned. In my textbook the following is said of the Pauli principle: I was wondering if someone can tip the veil of these arguments a little bit. Obviously, spin has a lot to do with it. I...

This is just an intuitive question, sparked by studying my courses. I haven't got the time to elaborate or search much myself at the moment, my apologies for this. I was wondering if there was a relation between quantum probability and entropy. Naive formulation of entropy is that a system...

Hey Status, of course! That's great, I didn't realize you were allowed to treat simple functions as distributions/test functions interchangably. That is, I'd seen the property, but not what it was useful for. Jezuz, indeed, when aforementioned trick is allowed, it comes down to...

Homework Statement Show that, in a distributional sense, x* Pv(1/x) = 1 Homework Equations The function 1/x cannot be integrated locally in the origin. Nevertheless, int(1/x, x=-1..1) =0, and thus convergent. Therefore, one defines the (non-regular) distribution...

I read somewhere the dictum that 'nothing can be done without at least a material base' ; the way the term matter was employed in this text implied that vacuum, 'empty' space, was to be viewed as matter-less. This would mean that in empty space, nothing at all can be done. This leads to an...

What are the available theories to explain the amount of energy concentrated in quasars? And what are possible problems in those theories? I don't have any background in this, I'm just trying to ascertain whether the philosophy of technology book I'm reading is still up to date. Thanks.
