"Fermat's Last Theorem's First Cousin," by Dana Mackenzie. *Science,* 4February 2000, pages 792-793.

The "Langlands Program" is a set of conjectures that have had an enormousimpact on number theory. Formulated by mathematician Robert Langlands, theseconjectures suggest deep and surprising connections between mathematical areasthat are very different. One of the reasons Andrew Wiles's proof of Fermat'sLast Theorem was so important is that it helped to push forward the LanglandsProgram. Now the French mathematician Laurent Lafforgue has supplied the proofof another piece of the program. This article describes the Langlands Programand the work of Lafforgue.
