The Disquisitiones Arithmeticae

"The Disquisitiones Arithmeticae," written by the mathematician Carl Friedrich Gauss in 1801, is a groundbreaking work in number theory. In it, Gauss explores properties of integers, introducing concepts such as modular arithmetic, which deals with remainders when dividing. The book also investigates quadratic residues and introduces the idea of proofs, laying a foundation for modern mathematics. Gauss’s rigorous approach and innovative ideas significantly advanced the field, influencing countless mathematicians and establishing him as a key figure in mathematics. This work is often regarded as one of the most important texts in the history of mathematics.
