SLAS Regular Meeting
Friday, October 21, 2016 7:30pm
McDonnell Hall, Washington University

Splitting Hairs Over the
Distance to the Nearest Star
Dr. Kater Murch
Washington University

Dr. Kater Murch of Washington University will be featured at the October meeting of the St. Louis Astronomical Society. The meeting will begin at 7:30 PM Friday, October 21, in McDonnell Hall, Room 162, on the Washington University campus, Saint Louis, MO 63130.

On September 14, 2015, ripples in the fabric of the universe – gravitational waves – were detected by the new LIGO (Laser Interferometer Gravitational-Wave Observatory) facility. The waves were caused by the merger of two black holes far away in space, more than 1.3 billion years ago. That violent event stretched and compressed space by less than the width of an atom. The measurement of that small of a ripple challenges our most advanced technology. It also pushes the limits allowed by quantum mechanics, the branch of physics involved with matter and energy at very small scales. Dr. Murch will talk about the limits on the precision of measurements imposed by quantum mechanics. He will explain how scientists using LIGO and other instruments are learning to view the universe through gravitational waves rather than light waves.

Dr. Kater Murch is an Assistant Professor in the Department of Physics at Washington University. He received his Doctoral degree from the University of California in 2008 and joined the Washington University faculty in 2013. His research interests involve superconducting electrical circuits, quantum
computers, and experiments on the limits of quantum measurement.
