🤔Proof Theory

What do you learn in Proof Theory

Proof Theory digs into the nitty-gritty of mathematical reasoning. You'll explore formal systems, logical deduction, and the foundations of mathematics. The course covers topics like propositional and predicate logic, natural deduction, sequent calculus, and the Curry-Howard correspondence. You'll also dive into consistency, completeness, and decidability of formal systems.

Is Proof Theory hard?

Proof Theory can be pretty challenging, not gonna lie. It's abstract and requires a solid grasp of logic and mathematical thinking. The concepts can get pretty mind-bending, especially when you start dealing with meta-mathematics. But don't panic - if you've got a knack for logical reasoning and enjoy puzzling through complex ideas, you might find it more fascinating than difficult.

Tips for taking Proof Theory in college
