This is an introductory chemistry course for students with an unusually strong background in chemistry. Knowledge of calculus is recommended. Emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. The course also covers applications of basic principles to problems in metal coordination chemistry, organic chemistry, and biological chemistry.

Yock talks about the costs versus the charges of medical stents. A cynical approach is that the actual metal stents themselves cost 80-90 cents to make and their charge is about $1200. However, there is an enormous amount of R&D effort to get it approved, he says. For example, a clinical trial can cost as much as 10 millon dollars.
