From Gravitons to Electrons: the Discovery of GW151226

Colloquium Preview

Date: Thursday, February 23rd, 2017

Speaker:  Sarah Caudill, University of Wisconsin-Milwaukee


LIGO’s detection of the first gravitational wave signal, GW150914, ushered in the era of gravitational wave astronomy with quite a bang, giving us a measurement of the heaviest stellar mass black holes to date and providing new stringent tests of general relativity. However, the detection of the second signal, GW151226, on December 26, 2015 was arguably just as exciting. I will describe the technology that allowed this signal to be detected just 70 seconds

Richard Taylor Profiled in The Atlantic About why Fractals are Soothing

You can read the full article here:

It makes sense that our visual cortex would feel most at home
