Notes for a series of lectures prepared for the Undergraduate Summer
Research Assistants of the C&O Department in 2009.
A survey of the recent work of Julius Borcea and Petter Br"and'en
on their multivariate generalization of the theory of univariate
polynomials with only real roots, and its applications. This includes
a very short (but complete!) account of Gurvits's proof of the van der
Waerden Conjecture.
Commissioned by the AMS for the Current Events Bulletin at the San Francisco
meeting in January, 2010.
``Unfortunately, in mathematics philosophy is permanently condemned
to play second fiddle to algebra.''
