Weighing Neutrinos

Neutrino oscillation experiments performed throughout the latter half of the twentieth century have yielded valuable information on the nature of neutrino masses and mixings. The evidence gathered has provided solid evidence for non-zero neutrino masses. As we begin the 21st century, a new suite of precision experiments is coming online to provide greater insight into the physics and nature of neutrino masses. This talk will review our current state of knowledge on neutrino masses, and how new experiments and cosmological observations will complement that knowledge in the years to come.
