Pascal's 1640 mathematical essay at age 16 — Pascal's theorem
Essai pour les coniques ("Essay on Conic Sections," 1640) is Blaise Pascal's early mathematical essay, composed at age 16. The work establishes "Pascal's theorem" on conic sections (the hexagrammum mysticum) — a foundational result of projective geometry. Among the earliest major works in projective geometry; influenced by Desargues.
