ELI5: Explain Like I'm 5

Drinfeld module

A Drinfeld Module is a type of mathematical object that looks a bit like a wheel. It has a round circle at the center, and around that circle are smaller circles that each have a number written in them. Like a wheel, you can go around the big circle and then jump to the smaller circle that has the same number. This makes it easier to do certain kinds of math problems, like multiplying or dividing large numbers.
