Hi, could someone direct me or recommend me some materials which deal with those problems? I would like to get deeper understanding of it (I know it requires qm), see how exactly such things happens and be able to quantify it (not just with phenomenological theory). For example when I get...

High voltage transformer and vacuum tube, long time ago. Ok that could work, but it's a bit violent for my taste. If I planed to kill myself with my own stupidity, it wouldn't be your fault, but don't worry at this point I'm here just to bounce of ideas (or gain them would be more precise right...

I remember all that from electrodynamics courses, the engineering point is difficulty here, I think I've never heard of electrostatic generator completely without mechanical parts.

Well yes, sorry I didn't rule this out from the start. I had in mind something little bit more stockpiling, so let's take it to as high voltages as possible (until it starts leak out too quickly by ionization of its surroundings). I will probably disappoint you but I just want efficient way for...

Nothing big, few volts (but as much as could be efficiently squeezed out of it). Well ground and spoon for example... Purpose would be to charge a metal object attached to the electrode.

Without moving macroscopic parts... No van de Graaff generators or piezo-something - just normal circuit that would used a battery at one point and on the other there would be macroscopicly charged electrode. :-)

I'm playing with http://arxiv.org/abs/1003.0561 It works fine for things like perihelion precession, bending of light etc. I've read about ADM formalism in general but practical usage without examples or practice and experience is another thing.

Thank you Muphrid. :) That would cover time dilation due to the relative velocity. I just wonder if its really so simple in the presence of gravitation field. I'll think about that in some better hour when my mind will working...

I'm sorry for poor description of the problem. When I've said I don't have a metric I have meant that I can't solve E.e. analyticly because configuration is too complex. If anything, I would have to get information about the metric numerically from the simulation itself. Lets say I would like...

Hello, lets say I have Hamiltonian aproximation H(\vec{x}_a,\vec{p}_a) of gravitational interaction that can be used for n-body simulation of mass particles and photons. Spacetime curved by simulated particles would be asymptoticly flat. But I don't have a metric etc. All I have is evolution...
