And mathematics, and engineering, and statistics, and economics, and physical chemistry, and astronomy and ... (please don't comment on things you don't understand)
...and Chemical Physics.
There are indeed many applications for Calculus but almost everyone I know working in a field that requires calculus, even intense and daily use of calculus has software for the math. They are paid to think, plank an manage not calculate.
I was an honors, straight A kind of student. I even loved math until I got the 7th grade teacher from hell who ruined it and I never recovered the love even though I was still quite capable and proficient at it. I went back and forth on a future career, everything from Archaeologist, Physicist to Stock Broker. When I took Calculus in high school after the first few weeks I realized that even if I became a physicist I would never use this. If I became a physics professor and was teaching I would use it but when it comes time to fire up the super-collider, Jimmy John ain’t ciphering that by hand. Do computers break, do you have Apollo 13 moments? Yes, but that doesn’t mean you build an education and waste valuable classroom time based on that scenario.
