Mathematical Theory of Everything
One hears very often phycists speaking about the "theory of everything", which is something of a holly grail for them. To quote Wikipedia : "A theory of everything, final theory, ultimate theory, unified field theory or master theory is a hypothetical, singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe. Finding a theory of everything is one of the major unsolved problems in physics." Well, the thing is, in Mathematics, we do in fact have such a theory! (Even though it gets comparably less publicity.) More precisely, we have a master theory that gives singular, all-encompassing, coherent theoretical framework of mathematics which links together all aspects of the MATHEMATICAL universe . (The other part, that it "fully explains" everything, that's work in progress. 😄) This theory is called Zermelo-Frankel Set Theory with Axiom of Choice , or in short, ZFC. Let me try t...
