How can light measure movements smaller than an atomic nucleus? Optomechanical systems use the radiation pressure of light to control tiny vibrations and even create quantum mechanical states. This opens up new possibilities for gravitational wave detectors, quantum sensors, and the networking of future quantum computers. 00:00 – Welcome & Introduction: Insights into Optomechanical Technologies 00:46 – The Power of Light: Comet Tails & Radiation Pressure 01:41 – Historical Overview: From Kepler to Experimental Confirmation 02:56 – Why is the power of light so difficult to measure?
