    Lagrangian for relativistic angular momentum

    Hi everyone, I have a question that can't solve. Does exist a lagrangian for the relativistic angular momentum (AM)? I can't even understand the question because it has no sense for me... I mean, the lagrangian is a scalar function of the system(particle,field,...), it isn't a function FOR the...

    Physics Which is the job of a physicist in a nuclear central?

    Hi everyone! I'm near to get a physics degree. Always like me nuclear physics, how can energy be obtained by a little cuantity of matter... I want to ask you,if you know, which is the work/tasks of a physicist in a nuclear central (if they can work there :) ). I would like to be more...

    Eigenvalues of a string with fixed ends and a mass in the middle

    Hi there. First of all, sorry for my bad english. I ´m trying to solve next exercise, from Vibrations and Waves in Continuos Mechanical Systems (Hagedorn, DasGupta): Determine the eigenfrequencies and mode-shapes of transverse vibration of a taut string with fixed ends and a discrete mass in the...
