Perhaps at /dev-mathjax. The png based image math is hard to read on a high resolution (retina) display.

Here is a great treatment: http://www.continuummechanics.org/cm/materialderivative.html with a worked out example. Do this example in 2D.

Introduce `arg`, `Im`, `Re` (or maybe `im`, `re`). So, in particular, write things like: ``` arg(z) = atan2(im(z), re(z)) ``` and not ``` arg(x+iy) = atan2(y, x) ``` because the...

Reported by Liguang G. Jiao. http://theoretical-physics.net/dev/src/quantum/hf.html#two-particle In the final form of the two-electron potential matrix , I think there is no factor (2L+1). This factor will be eliminated in constructing...

Check Gaunt coefficients and fix if needed

Reported by László Oroszlány and Laszlo Szunyogh. There is a small mistake (or just rather an inconsistency) in the way you define the c-type Gaunt coefficients in the section about...

Here are great QM notes: http://galileo.phys.virginia.edu/classes/751.mf1i.fall02/ We can polish our QM section using it.

John: DFT ground state does not necessarily have 7s higher in energy than 6d. In fact, my featom code finds the following ground state energies/occupations for LDA (using Fermi-Dirac occupation...

In particular John's comment: You have phi for "potential energy" and V for "potential" instead of the other way around.
