Gravitational waves detection and measurements, the discovery of which was announced to the world in 2016, is a fast moving field. Several events have been detected in LIGO and LIGO+VIRGO, and in spectacular coincidence with gamma ray burst detectors. Clearly we are just at the start of this fast developing discipline. These lectures will discuss the experimental aspects of gravitational wave detection, the information gathered from the present experimental results and the road ahead
for these experiments.
