answer:First, Philosophy. It was both the teacher and the course that made the whole thing wonderful. It was taught by an ex-Jesuit at a Jesuit University and he made the course come alive. He was the first to make me stop and think, really think, for myself. Secondly, Astronomy. While the teacher was good the subject matter was/is unbelievably fascinating. Discussions of black holes and red dwarfs and the unending-ness of the Universe haunt and fascinate me to this day. It was this course that taught me how to use a telescope and to find and map constellations and to see and somewhat understand what the naked eye can’t see.
