You need to know calculus, since without it you can't really understand physics. Without physics, you can't really understand much of anything in this physical Universe. It will be essential for you to absorb a great many facts about the Universe, both in this course, and in your life, if you are to make much sense of it. It's also a harmful myth that if you're interested in science, you must be some sort of genius, and therefore will find science easy. All the sciences, including calculus, physics, chemistry, computing, and astronomy, aren't easy.
Persistence is the key here, and in so much else of life.
Reading science texts and other technical literature is much more intense than reading other literature. It helps a lot to take notes when reading. Class participation is also essential. I want you to pursue your education actively. Last updated 1999 December 28.
