The triumph of LIGO’s confirmation, at this 100th anniversary of Einstein’s prophetic work, both of gravitational wave propagation and their full GR source dynamics is astounding enough to recount. An exciting new field has been launched, and grown in either its experimental or astrophysical scope beyond the compass of one talk. Only briefly, I will first present an overview of the LIGO instruments with insight into their roots in the classic “interferometer of Michelson” (findings so inspirational to Einstein) over 130 years and > 1010 in metric resolution ago. Next, the amazing nature of the binary black hole coalescence events detected will be spotlighted. Rather than due to particular conspicuous technical innovations, I emphasize that human scientific vision sustained this quest from the time of Weber and realization that BHs and GWs should be palpable. Certainly the culmination in LIGO’s discovery 60 years later is essentially due to the perseverance and faith of remarkable visionaries carrying on through much adversity and periods of doubt. Turning from the drama, I’ll take a personal, insider view of a selection of fascinating technical challenges faced in LIGO. The message will be that focused, meticulous engineering carried out by dedicated and ingenious scientists will carry the day. Seemingly unglamorous details such as thorough understanding of materials thermal and mechanical characteristics; vacuum technology; and ultra-low noise servo-mechanical strategies take center stage!
