Fire restoration work is expected to continue into early November. The main stairwell and office wing on both second and third floors of the Physics building will be closed until necessary repairs to the main stairwell are completed.
Administrative offices have been relocated to PHY 345.
Please contact individual faculty members to request appointments, as many faculty have been relocated during this process.
Please do not cross any caution tapes whilst in the building.

Refreshments in PHY 151 starting at 3:30 pm
This December the Nobel prize will be awarded for the direct detection of gravitational waves two years ago. This capped off a century of controversy over their existence, ranging from questions about their nature, tantalizing clues of their influence, and dubious claims of detection. The gravitational waves observed by the Laser Interferometer Gravitational-Wave Observatory (LIGO) in October, 2015, recorded the death throws of two black holes. In doing so, they have provided critical verification of dynamical elements of Einstein's general relativity and have unlocked a new window on the very massive and very compact. I will review the history of gravitational waves, describe the extraordinary technological feat required to detect their subtle signatures, the implications of the five LIGO detections thus far, and the bright future of gravitational wave astronomy for understanding the dark universe.
