Build up of charge in cloud, discharges on the earth (ground).

Charge always wants to "discharge", it doenst like to build up (can only build up so much), because at some point the force of electron-electron (or any charge particles) replusion will be too great.

Okay serious question.
I once read about QED and feynman's field theory about virtual photons and how charged particles emit and absorb those virtual photons which then causes attraction/repulsion (how magnets work)

Is that a theory that is still possible? Has it been proved/disproved?
Are there other theories about that out there?

No, while there is physics involved in a MHD (technically everything has physics in it), it is just applications.

Hence that is more of a faggot question (engineering). NOT really a physics question (hence I ignored it).

LBE is just a particular way to solve fluid systems (or fluid like systems), this is just math. No one really uses this shit but engineers, again it is all for aplications. It is all very basic (usually numerical) shit.

I reckon you're an mech engineer (a faggot)?

Nice question, Never heard of the term "feynmans field thoery", I think you just mean current QED in general.

Yeah, virtual particles are the particles responsible for any "force" transmission. The photons propogate the EM charge, the W,Z propograte the Weak charge, and the Gluons the strong charge.

As far as QED goes, this thoery has pretty much been proven. QED is one on the best thoeries out there, with thoery and observations in perfect agreement.

Technically, I am sure there are other theories out there, just like some people still believe the earth is flat. But it is pretty much all nonsesne. QED is perfect for its range of validity, and answer all questions it relates to.

The uncertainty is generated by non-comutive algebra (as QM is written using operator thoery).

It is pretty straight forward, if you have two operators that don't commute, then an uncertiny is formed between those observables.

The gluon, W, and Z have all been found.
You technically cannot physically find the virtual photon, it would make it non virtual by defintion. But it too is "found".

A problem lies in your understanding of the "found" concept. At the subatomic scale, we do not have to physically isolate and "see" a particle for it to be considered "found". You can gather proof of existence by other means. Isolating subatomic particles is often impossibe.

This is a good book on introductory particle physics. You may need to study alittle regular physics first to be able to understand it though.

Ohh, fuck if anyone knows. I mean we know how gravity work on a grand scale. Einstiens GR has been verified numerous times. On a smale scale though, no one is sure how gravity works.

We assumed like all other forces there must be a force particle (the graviton), but that is basically as far as we got.

The problem is that gravity is so small comapred to all other forces. We can always ignore it in particle physics. Hence we really cant run tests for it in particle physics, not yet anyway.

This isn't fucking semantics. You should never dumb shit down to make it understandable if you are trading off accuracy. Saying a theory is proven is a fucking elementary mistake because, like that other guy said, there is a fundamental difference between not disproven and proven. Saying shit like that is what gives the public a wrong image of science.

It doesn't even help make things clearer anyway.

FYI: This is all engineering (faggotry) you speak of.

Well we don't have that level of tech to build it now. But maybe in the future, although modern Ion tech is very slow. Technically, you really dont need that much power to travel anywhere you want. You just need a few pushes every now and then. You will take a very very long time though.

I am not sure about the specifics of ion tech, again this is engineering (faggotry), not physics.

Well, I was under the impression that everyone thought in language, and that more or less couldnt be changed???

In anycase, I guess I would say that sometimes I think in "representations of equations", but this is only if I am really focusing on physics/math. I doubt that too much of the language sector of my brain has been effected.

I've heard a few years ago about a team of scientists that made a material with a negative refraction value, at the x-ray wave length. I didn't understand (and can't really remember) the details, but it was with a 2d chain of magnetic rings, all in a very exact size (several microns in diameter, I think).
The result was an object that made light (well, some parts of the spectrum, at least) go *around* it, making it invisible to those wavelengths.

I heard all this during a presentation at my university (The Technion), and I have failed in finding more information on the subject since. Help?

Good question,

Ok, so EM + Weak are supposed to be unified into the Electroweak. But there are tons of probelms with this, and it ends up looking just like a change of basis rather then an actual unifications (but thats another story).

So, at some energy the EM and Weak forces become one. Back when the universe was hotter, they were one, then they split in two. Some werid shit happened during the split that we are trying to figure out. Of key importance if why the "force" particles have differnt masses. The Higgs is supposed to help explain why the Photon got no mass while the W,Z became massive. Basically how things can aquire mass in this way.

Sure, you can't measure both position and momentum to arbitrary accuracy, but that doesn't mean you can't measure both at once, as long as your accuracy on both is limited. One way of measuring momentum (actually, the ratio of charge and momentum) is by putting the detector in a magnetic field and just seeing how much the particle bends with position measurements. Spin is usually inferred from the angular distribution of decay products.
