I dunno. I only did a three year (Hons) degree ;) Can do some quantum 
stuff, and pde's, sometimes, but failed conic sections till years later. 
Perhaps because they have little to do with chemistry. i digress.

If you keep it to atoms made of nuclei and electrons, without going into 
the quantum physics but with a little electron cloud handwavium, it can 
be fairly understandable. But often l o o o o n n g, especially if you 
include reaction mechanisms.

One of my favourites is when in  a house to describe the rooms as 
electron clouds of atoms, each with one nucleus - just barely visible to 
scale - in each room.

But even if you do get it all in there, and get it understandable (and 
correct, of course), does it help the average citizen or even 
tekki-sheddi? Possibly not. So it squirms back into the murk of 
knowledge which is never going to be used.

Or gets relegated to Google storage - keep the outline, search for 
details if/when needed. Especially in chemistry where there are over a 
billion entries in the Beilstein/Gmelin/Reaxys database...

In places like this I try to curate for a curious intelligent person, 
with a smattering of science, to feel that I answered a question or they 
learned something, hopefully light enough to float in the murk... or an 
outline worth remembering.
