This is an ad hoc video podcast of short films demonstrating basic scientific principles. The fields covered tenuously include Biology, Physics and Chemistry. This stuff is just for fun so please don't quote anything you heard here in a science essay. The files available are encoded in H.264 format and packaged as M4V files that will play in iTunes and on (video) iPods. If you don't want to do it that way then YouTube.com is also hosting them in their lovely flash player format. If you have any suggestions for future demos, please drop me a line at doctor.campbell@jambell.com.
