The Science History Institute is a multifaceted nonprofit organization whose mission is to preserve and celebrate our scientific and technological culture and to make it accessible for investigation and knowledge creation.
This site is written and maintained by a retired chemistry professor in England. Although there are specific references to topics covered in the syllabi for British students, basic concepts of chemistry that students everywhere tend to have problems understanding are explained.
Originating from the University of Sheffield, this site maintains links to thousands of web sites related to chemistry worldwide. The University is currently updating the software to maintain the integrity of the links.
