Breaking The Heisenberg Uncertainty Principle

The video explores the Heisenberg uncertainty principle, its historical context, and its implications for precision in measurement. It highlights how engineers and physicists have developed techniques to push the limits of this principle, particularly in the context of LIGO's detection of gravitational waves. By using squeezed light and quantum entanglement, LIGO can measure tiny changes in space-time, demonstrating the potential of quantum mechanics to enhance measurement precision. The video concludes with a discussion on future applications, such as improving GPS accuracy.
