Interferometry: From Nothing to Black Holes
Gravitational waves were detected by LIGO (Laser Interferometer Gravitational-waves Observatory). This monumental discovery comes precisely 100 years after Einstein predicted these ripples in space-time. At the heart of this phenomenal outcome, lies a marvel of technological powers-a LASER interferometer. In this popular level talk Dr. Muhammad Sabieh Anwar will recount, how the phenomenon of interference shapes our present day picture of Physics. Right from dispelling the notion of an all pervasive ether, finding signature of "matter waves", probing molecules on stars a single photon interfering with itself, to the recent signatures of the gravitational waves, these beautiful machines called interferometers harbor immense power as one of the most important tools for scientific discovery. He will present examples where the phenomenon of interference has enriched special relativity, general relativity, the foundations of quantum mechanics and quantum optics.
