Gravitational Waves: History and Detection

This lecture covers the history of gravitational waves, from Einstein's predictions to the first detection by LIGO. It explains the concept of gravitational waves, their propagation, and detection methods. The lecture also delves into the significance of the first binary pulsar detection, the LIGO project, and the expected amplitude of gravitational waves. Various experiments and projects related to gravitational wave astronomy, such as LISA and KAGRA, are discussed, along with the challenges and future prospects in the field.
