| humble when discussing _anything_ and Feynman will always have my
| deep gratitude for inspiring such thinking early in my life.

| Feynman's equations suggested that we only needed five. We
| decided to play it safe and ignore Feynman.

| I always felt it strange that people discount the value of
| calculus, but maybe it is just that most professionals really
| don't understand calculus that well? It is really useful for so
| many things, and if you are good at understanding data and how to
| properly approximate things then you come up with magical
| solutions to otherwise intractable problems with it.

| That sounds really great and all, but I do admit to wishing
| that depressing word "things" wasn't standing in the way of
| some accurate examples. I do understand you said calculus helps
| you to approximate, though.
