Are you a subhuman?

My differential equations class is going really well, as is my calculus class. If I could have read that sentence at the start of the semester, that would have greatly relieved some initial anxiety. I churned out a 98.5% on my midterm last week for differential equations and I'm coming up on my second midterm for calculus (next Tuesday). And since this chapter of calculus feels much easier than the first chapter, I suspect I will do well (with some really focused studying, of course). For now, here are two quotes my instructor included in our differential equations syllabus at the start of the semester, which are just plain awesome:

"It is unworthy of excellent men to lose hours like slaves in the labor of calculation which could be relegated to anyone else if machines were used." — GOTTFRIED LEIBNIZ (mathematician, philosopher)

"Anyone who cannot cope with mathematics is not fully human. At best he is a tolerable subhuman who has learned to wear shoes, bathe, and not make messes in the house." — ROBERT HEINLEIN (author), Time Enough for Love
