Looking to the Past

The video explores how to make progress in physics without experimental guidance, focusing on the concept of space-time. It discusses the challenges of understanding space-time, drawing parallels to the historical shift from classical to quantum mechanics. The speaker emphasizes the need to rethink classical physics and introduces the principle of least action as a way to understand these concepts. The video highlights the importance of finding new ways to conceptualize existing theories to make significant advancements.
