Describe your latest book/project.
The Little Book of String Theory is a short but searching account of modern string theory. As a practitioner of string theory, I wanted to bring it to a popular audience in a way that would cut to the main points of the subject in relatively few words.
Describe your favorite childhood teacher and how that teacher influenced you.
In seventh grade I had a math teacher named Gary Kreutzer who was fun and enthusiastic and also knew a lot of math. He was often willing to work with me by myself, and I remember learning about polynomials, systems of equations, and prime numbers with him.
