Both the tutorials by Smellenbergh ( http://users.skynet.be/smellenbergh
) and Mike Econym (http://www.econym.demon.co.uk/isotut/nfunc2.htm)
quote the phrase from the source code "a well known function in quantum
mechanics" when referring to the "func_11" in the  isosurface libraries.
And both of them seem nonplussed by the phrase "a well known."

I'm a metallurgical engineer, not a doc--er--programmer.  I remember
some college chemistry. It looks a whole lot like the  shape of the
electron density cloud for one of the d orbitals. The d orbital is the
electron thingy that starts getting filled when you get to potassium in
the periodic table.   See:

Just in case anyone were demoralized by not knowing what it was: it's
probably something everyone was exposed to at one
time in high school chemistry.  ;)

Interesting link you got there, esp the bit on number systems
