At the beginning I took this course because I was interested in doing parallel programming that scientific computing usually requires. But, I get much more than that: I learn how to visualize mathematics, which is very important if you have ever read Richard Feynman's Surely You're Joking, Mr. Feynman! Mathematics is not to be read as fancy symbols, it is meant to express precise semantics of what one has in his/her mind and to understand precisely what one has in his/her mind.
