Pretty much any serious statistical model or experiment on anything will use basic calculus to interpret data Anything that exponentially grows or decays (radioactive matter, bacteria, population growth, etc. ) Anything that's built to be structurally sound Anything that uses the EM spectra (radio, microwaves, visible light, etc. ) All scientific industries use calculus practically constantly And on and on and on In reality, it's rarely pure theoretical calculus that's being done. Rather, another branch of math based on and built from the principles and results of calculus is primarily used called differential equations.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
