A Conversation for Size Matters: How big are molecules?
Fantastic!

I'm writing up a Physical Chemistry practical, and trying to find a typical length of a C-N triple bond to see if I've got sane results. One Google search later, and this entry appears! I should've known H2G2 would have the answer.
Fantastic!

Way cool to find out my Entry is useful. And on google.
Thanks for the feedback.
You may be interested to know the following: (Geektalk follows) I am a physico chemist doing nano-stuff, and at one occasion we had to figure out how long some molecules were. To do it I used this very table I entered here and a drawing pen. I found out the molecule in question had a size of 1.1 nm (just enough to go into a certain pore I needed it to go in). When I was asked how I estimated the size everyone was expecting some acronym of a computerprogramme, instead I just said, I drew it and used a ruler (!!!). OK everyone sighed and gave the problem to a supercomputer simulator guy. He figured out the molecule was 0.8 nm big. When finally we received the X-ray structure of the molecule (the real measure) it turned out it was 1.15. My result was 0.05 nm off!!! Imagine my satisfaction!

I get the feeling that all the computer/theoretical type practicals we've done are designed to kick the notion into us that Computers Get It Wrong Sometimes.
Fantastic!

The output of a computer is just as good as the programme. And programmes are man-made constructs.
The only good thing about computers is that they are really fast and they don't bitch about doing boring stuff over and over again.
