hello there: I am a graduate in physics, but unfortunately in my country there are not many places for me to work so, I was wondeing if I could get a Job in CERN... Can anyone tell me if there are any chances for me to work there? Thanks

I hace read in Electrodynamics from griffiths chapter 2, that, whenever acavity is inside an spherical conductor, for the outside it acts as if there was a point cherge at the center... But what if thew conductor has another shape, for example a revolution ellipsoid...?? how do you deal with...

When I wrote "without using magnetic fields" what I really meant was if there was any other way to distinguish for example the velocity of a charged particle besides the use of magnetic fields?

Hello: Can anyone please tell me how do they identify the particles in the detectors?+, for instance, how do you know if an electron is an electron and not a muon or some other negative charged particle in a detector (without using magnetic fields)?

Hi to everyone: Does anybody of you know when was the gluon detected?, and how do you detect gluons? I hope you can answer Thank you

Hello: Can you please explain me what the nuclear isospin is?. Is it a new kind of angular momentum?, and how was it detected ? Regards

Hello: There are many kinds of particle detectors, could you please explain me how does a multiwire chamber works? Regards

Hi: What's a gauge theory?, Is it just some kind of theory invariant with respect to some transformation? (like electrodynamics where the potentials are not sigle valued) and what is the importance of gauge theories in particle physics? Thanks

Hello: The nucleons insede a nuclei, interact only with the closest nucleons, How does QCD explain that the nuclear forces saturate? Thanks

Yes, malawi_ Glenn, That is exactly what I meant... Thanks

I am not saying that confinement can only be quantum. What I mean when I said that quarks are not found free in nature, is that is not possible to observe for example two quarks interacting macroscopically..or can they?

Hello: I've heard that quantum chromodynamics describes the strong interaction between quarks, but What is classical chromodynamics? as long as I know qurks are not found free in nature. Regards

Hello: In Classical mechanics, the lagrangian of a system is defined as the kinetic energy minus the potential energy, but is there any physical meaning of the lagrangian ?, and if there is, What is it? Regards

Hi: In experimental HEP, Why are higher energies associated with shorter distances , and by the way, in order to reach higher energies or shorter distances, an increase in the size of the detectors is needed, Could you please tell me why?. For instance Why do we meed a particle...

Hello: In quantum field theory, there is the Klein-Gordon Equation that describes particles with Spin 0, this equation reduces to the SchÖdinger equation when the non relativistic limit is taken, Does the Dirac equation that describes particles with spin ½, reduce to Pauli's...
