Taming The Wild West Of Internet Based Chemistry You Can Help

1,448

Published on

I am an adjunct prof at University of North Carolina Chapel Hill so when I stopped by yesterday for a business meeting I was informed that I had been lined up to give a talk to the students at 1pm. I had 20 minutes to prepare and assembled a mish-mash of information that might be of value to Citizen Chemists, those who might want to contribute to chemistry on the internet
