"Principia Mathematica" is a landmark work in mathematical logic and philosophy, authored by Alfred North Whitehead and Bertrand Russell between 1910 and 1913. The book aims to derive all mathematical truths from a set of axioms using formal logic, establishing a foundation for mathematics that emphasizes precision and clarity. The work is notable for its rigorous approach to logic and its influence on the development of set theory and computability. It introduced concepts that would later be crucial in fields like computer science and philosophy of mathematics, making it a significant contribution to both mathematics and logic.
