Episode notes

Einstein was trying to explain the symmetries of maxwell's very successful electromagnetism. He realized that what you called space, what oucalled time, was in some sense a choice of an observer to split four dimensional space time into the three of space and the one of time. Laurencin variance is different things moving at different velocities don't have any way of telling how fast they're moving only with respect to other things. The fact that i was relational notion was true even before lhe rentsin variants. There's galilean in varibise, which is still true for newtonian physics. Einstein adds this ingredient, that the way you

Quantum mechanics and general relativity are the two great triumphs of twentieth-century theoretical physics. Unfortunately, they don't play well together -- despite years of effort, we currently lack a completely successful quantum theory of gravity, although there are some promising ideas out there. Carlo Rovelli is a pioneer of one of those ideas, loop quantum gravity, as well as the bestselling author of such books as Seven Brief Lessons on Physics and the recent The Order of Time. We talk about how to make progress on this knotty problem, including whether string theory will play a role (Carlo thinks not).

In 1988, he and Abhay Ashtekar and Lee Smolin introduced the idea of loop quantum gravity. He is also the author of the "relational" interpretation of quantum mechanics.
