I was sent to MIT some years ago to learn about trajectories of projectiles.
The professor teaching the course was very understanding of a bunch of young louts who cared less about the curve of the bullet just as long as it hit the target.
We did learn the basics...and to his credit...he gave us all a passing mark.
I heard later that we were just about his last class...he died of cancer while we were in Viet Nam....no justice in this world for a man who just wanted to impart knowledge to people.
