Have a large RFI (Request for Information ) document to fill in answers to this week. Once the phone stops ringing I find that I can get ‘into flow’ and work more effectively on these things. But that needs strong and regular caffeine input.

A couple of weeks ago I downloaded some cool software that generates 3D models of molecules. The idea was to encourage Hannah to learn a bit more about chemistry, although I played with it more than she did.

Here’s a caffeine molecule model. The software is free, and there are lots of models out there on the Internet as well. I’ll post links to them shortly.
