Learn English – What do you call someone that doesn’t want to use something unless they understand it

By someone, I mean myself.

I acknowledge the fact that I use things anyways, but it bothers me so much to the point that the thought has become frustrating. I know I'll have to get used to it at some point in time, as I can't delve in to the world of atoms or quarks and all those subatomic structures any time soon.

I tried looking it up online, but the word doesn't seem to exist, that or I just don't know the term.

The only word which comes to mind is Cartesian. It's not 100% what you are looking for, but maybe close enough?
