"The theory of elliptic curves and modular forms is
one subject where the most diverse branches
of mathematics come together: complex analysis,
algebraic geometry, representation theory, number theory."
— Neal Koblitz, first sentence of
Introduction to Elliptic Curves and Modular Forms,
First Edition, Springer-Verlag, 1984
