Mathematics, thermodynamics, foundations of physics
As Matt Hogan said, I want to understand it all and I have to start somewhere, so why not spacetime. Current academia is too much focused on publishing irrelevant results, career development and so on. We need structures that allow for in-depth discussions, for the sake of knowledge, and that connect people with these interests and different backgrounds.
I think the BRCP can offer a platform to: i) share information/ interesting papers, etc; ii) organize meetings; iii) lobby our vision of science. We won’t change the world, but at least we can learn something from each other.
