But, they lost me at their "one equals zero" statement, below:

I think he's talking about (lower-case L) equals 0, where (lower case l) refers to the quantum number indicating which electron shell an electron is in (0 means the lowest shell, closest to the nucleus).

Some fonts hardly distinguish between "ell" and "one" characters at all; hence my misinterpretation of the character. In my #37, above, I used the "Geneva" font to show that what you claim is actually the case...
