Animating chemistry.

Using the three-dimensional nature of molecules and the visual power of computers, some chemists are animating their field. Literally.

Led by Nathan S. Lewis of the California Institute of Technology, these scientists are designing broadcast-quality animation to exhibit chemistry's physical concepts. Lewis wants students to learn chemistry "with vigor, instead of just obtaining numerical answers on topics they don't fully understand."

Using topflight animation technology, the chemists, with help from some undergraduates, will produce videotapes 8 to 10 minutes long demonstrating various aspects of physical chemistry. Called the Chemistry Animation Project, it also enjoys guidance from film industry animators and graphic designers.
