Many years ago he did computer graphics. Swami went into the history of mathematics, about how mathematicians look for patterns. He says that it's much more interesting than crunching formulas. Many patterns in biology can be expressed, and predicted by math. He then spoke about a new DNA base pair being synthesized and inserted into the E. Coli genome. This greatly increases the number of base pair possibilities in defining genes. Like I said, no ordinary teacher. His students are lucky, and had better keep up!
What caught my eye originally was the logo on his shirt.
