The ChemDoctor: Peter deLannoy
ChemDoctor is an educational web site committed to providing a free world class education in chemistry. The vision is to provide short chemistry videos that the viewer can use to learn chemistry. Current offerings include a large range of videos extending from the high school chemistry curriculum through university level general chemistry. The inspiration for ChemDoctor came from the Khan Academy and the viewer will notice the similarity of the platform used for instruction. In addtion to this web site more chemistry videos can be found at ChemDoctor.
ChemDoctor is devoted to helping you understand chemistry through the use of chemistry videos. Simply click on the link and you should find the video lesson you need. If not, leave a comment here or contact me at ChemDoctor or firstname.lastname@example.org and I will do what I can to rapidly produce the lesson you want.
The best way to use the videos is to perform the calculations pausing the media as needed. I also recommend having a periodic table handy.
