Hello I am looking for a certain paper by Albert Einstein (sometime between 1905 and 1920), where Einstein discusses Entropy - in this paper, he presents entropy, but then says that the term in the exponential or logarithm (cant remember which) need to be dimensionless. So he divides the term...

Hello, this one is doing my head in. I'm trying to plot and play with wavefunctions by moving the originm, but i need to do it in spherical coordinates. Suppose i have a function G(r',theta',phi'), centered at the origin of the system r',theta',phi'. I also have a similar...

thanks a lot clem, that really helps a lot...do you have reference by any chance?

hmm...thanks for the link friend, but it doesn't give me enough detail unfortunately :(

Hello, I have tried to look for related threads but could not find any. Please excuse me if this is a repetition. I was curious about the energy of an electric quadrupole moment in an electro-magnetic field. Basically, i am trying to follow first order perturbation theory and derive the...

thanks for the response...hmm, i can't seem to see a linear behavior in there, despite seeing a somewhat linear behavior when i plot it. Am i just visualizing something?

Hello, I am fairly new here, so thank you in advance for your help. This is not a homework problem, just one of curiosity based on my limited knowledge of asymptotic expansions. I'm curious about how the function ln(x) or ln(1+x) behaves for large values of x. Plotting in Matlab, I see a linear...

hi Jesse, thank you for the response. I went through the other derivation, and while it works well, I don't understand why you would need to introduce a third frame, which as you mentioned is galilean, but wrong because the correct transform would have to be lorentz. So it appears from your...

Hello friends, i am also following the derivation of Einstein in OEMB paper. However, i have a few questions that you may be able to help me with. When einstein says let x'=x-vt, it seems he is referring to a point stationary in the moving frame k, and moving at speed v. Thus, x' is the...
