Back to square one

Okay, remember how I said I think I've reached enlightenment? I haven't. Far from it. I've found two versions of the equations, both quoted in different sources. I thought maybe there's a typo in one until I've found about half the sources quoting one and theother one quoted the other. So I tried to fit the equation into the "bigger scheme of things" and hope that fits, and of course you get into all sorts of problems because of how the equations is defined. *sigh*

Anyway, it's going to be a LONG road to enlightenment. I'm still trying me best to figure out which one makes more sense. Otherwise I'm seeing my supervisor today anyway, so maybe he can shine some light into it. (Or tell me I'm not working hard enough :P)
