How to Find the Laws of Physics

Sat's a great example of starting from principles and then finding laws of physics, rather than starting from the other direction yet. It first we observed that nothing could go faster than the speed of light, and therefore, for dons have to move this way with these laws. And he did something similar when he developed general relativity, right? In general relativity, he said that acceleration is indistinguishable from gravitation, that you can't tell the difference between accelerating and being in a gravitational field. That principle led him to general ivity. You know, it's sort of like assumed some basic principles about what's allowed in the universe and what's not allowed, see what the consequences of that are
