The time has come to gather together and enjoy the company of other chemistry teachers at our annual Spring conference.  This year, it will be held on Saturday, May 2nd at Diablo Valley College in Pleasant Hill.  The theme of the conference will be Biophotonics which has to do with the use of light as a clinical and diagnostic tool to image, analyze, and manipulate living tissue in a minimal and noninvasive manner.  Biophotonics is widely regarded as the key science upon which the next generation of clinical tools and biomedical research instruments will be based.
