Bhargava, Manjul: The fifteen theorem of Conway and Schneeberger

Abstract
The classical "Four Squares Theorem" of Lagrange asserts that any
positive integer can be expressed as the sum of four
squares; that is, the quadratic form a2 + b2 + c2 + d2 represents
all (positive) integers. A general quadratic
form represents all positive integers if it represents
the integers from 1 to 15.

"A non-Archimedean analog of the classical Big Picard Theorem,
which says that a holomorphic map from the punctured disc to a
Riemann surface of hyperbolic type extends accross the puncture"
