i like the way they use simpler systems, and known concepts to leverage up into more complex understanding. this seems to me the basis of "education", a structure to teach people how to build upon things they have learned, and especially understood, to walk boldly into the unknown, and believing they have a chance to understand.

Still and all, if you learn that you know less the more you learn, it contributes to the sense of awe in the universe. Humility is a great feedback mech.
