    Graduate Does the Lagrangian Explicitly Involve Time in Hamiltonian Mechanics?

    Lagrangian is a function of ... Since Lagrangian is a function of q, q dot & time, then why in describing the Hamiltonian (H), L does not involve time explicitly? as H = (p*q dot) - L (q, q dot).

    Graduate Lagrangian of 1D Motion: Finding Particle Coordinate x at Time t

    i have L of particle m in 1D motion, but how i can find the coordinate of particle x at time t?

    Undergrad Relative humidity at negative temperature

    as we know at zero degree temp. water condense to form ice. so what will be the relative humidity of a chamber at a temperature below zero degree temp.? will it be nagative or what?

    Graduate Probabality of jumping of e in K-e capture.

    ok. so does 2s or 3s also try to fill up the vacany? during the transition from 2p & 3p screening effect is also apply? from which i.e 2s or 2p it is readily jump to 1s?

    Graduate Probabality of jumping of e in K-e capture.

    as we know in L orbit there are two shell 2s & 2p. suppuse for an atom both shells are occupied , then what is the probabality of jumping of any electron from 2s & 2p shell to lower 1s in the process of K-electron capture process?

    so is it a elastic collision?

    Graduate Energy loss in collision in oscillator

    Is there any loss of energy of a particel (electron) while getting collission with the walls of a finite square/rectangular barrier? since there is a enormous no. of collision a particle takes.

    Graduate Physical intrepretation of Sr.E.

    you all discuss so much but my confusion remain same that how we can intrepretate the Sr.E. (which is actual a complex function), Is there any expremental evidence or proof of this complex function in order to see in the nature?

    Graduate Physical intrepretation of Sr.E.

    as we know whole Quantum mechanics is based on Schrondinger Equation, but how for a wave we can physically vizualize/interprete this eq. in the context of wave function?

    Graduate Transition states of electron in atom

    can this process be reverisible?

    Graduate Transition states of electron in atom

    my thought is that when we apply a very high energy to an ionised atom can there is any probability of production of charge so that this ion become a neutral one? is there any way to transfer an ion to neutral atom by any way by suppling any form of energy?

    Graduate Transition states of electron in atom

    ok. but my confusion is still for: why there is need to jump from excited state to ground state since the electron has more energy than earlier? it is only because of what above thermo. said? or anything else?
