The Four Greatest Ideas in Physics

In his address, the speaker Prof. Dr. Pervez Hoodbhoy aptly explained the four greatest ideas in physics: relativity, quantum mechanics, electro-weak unification and the string theory. These ideas had changed the very face of twentieth century physics and taken mankind into more exciting nooks and corners of the known and the unknown universes. The content of the lecture was aimed for the lay masses, and therefore commanded a lot of eager interest from people of all backgrounds. The lecture was followed by an active question and answer session, lasting another thirty minutes.
