The idea of warmup exercises was developed by Evelyn Patterson and Greg Novak http://www.usafa.af.mil/dfp/physics/webphysics. The cgi script was developed by Ching-Wan Yip.
Some of the questions on the warmup exercises are taken from Eric Mazur's book, Peer Instruction.
On the research page the background with red blood cells was taken from http://www.fpg.unc.edu/~sickle/events.htm#NSCDP99.
Also on the research page, the sickle cells image was taken from http://cer.hs.washington.edu/John/ss.htm.
Everything else was developed by D. B. Kim-Shapiro.
