Proof Theory
Proof Theory is a field of logic focused on understanding the nature of proofs. Just like a detective gathers clues to solve a mystery, a proof theorist studies the 'clues' or steps in mathematical proofs to understand the patterns, strengths, or limitations. It can reveal not only if an argument is true or false, but why and how. It's like understanding the recipe to a dish, not just the final meal.

Proof theory is a branch of mathematical logic that examines the structure and nature of mathematical proofs. It seeks to formalize the process of proving statements within a deductive system. By analyzing how conclusions can be derived from axioms and previously established theorems, proof theory helps clarify the foundations of mathematics and logic. This area explores different proof systems, such as natural deduction or sequent calculus, and investigates their properties, including consistency and completeness. Ultimately, proof theory provides insights into the validity of arguments and the reliability of mathematical reasoning.
