And I believe it's a problem of the education system. Back in high school they had me solve dozens, if not hundreds, of derivates and integrals, it was not until college that a fantasic teacher had the guts to come up with his own syllabus, threw away all the "traditional" calculus and taught us what was a diffeeential, what were we doing when getting a derivative and an integral, completely changed my mind.
