Arithmetic Geometer Jordan Ellenberg is a mathematician. He teaches his college students how to create codes, using math. Have you ever made up a secret code and used it? How did it work? Who did …
Arithmetic geometers, like mathematician Jordan Ellenberg, explore the ways number theory and geometry overlap. For instance: the number of solutions to an equation in whole numbers is related in a still-mysterious way to the shape of the region described by the equation’s solution set in real and complex numbers!
