Haha, this is about 3rd (or 4th) time i'm posting this now, but I really need some good help. Right now I'm trying to decide whether to write research on usage of calculus in physics or usage of calculus in chemistry, but I need more specific topics and resources. I kinda decided that I want to write about usage of process of differentiation in describing motions in physics, but again, I need some good sources. But, if you have good sources for usage of calculus different topics in both physics and chemistry, it will be awesome. Thanks for your help.
