Who was Pierre Frédéric Sarrus?
Pierre Frédéric Sarrus was a French mathematician.
Sarrus was professor at the University of Strasbourg, France and member of the French Academy of Sciences in Paris. He is author of several treatises, including one on the solution of numeric equations with multiple unknowns; one on multiple integrals and their integrability conditions; one on the determination of the orbits of the comets. He also discovered a mnemonic rule for solving the determinant of a 3-by-3 matrix, named Sarrus' scheme, which provides an easy-to-remember method of working out the determinant of a 3-by-3 matrix. Sarrus also demonstrated the fundamental lemma of the calculus of variations.
Sarrus numbers are pseudoprimes to base 2.
Sarrus also developed the Sarrus linkage, the first linkage capable of transforming rotary motion into perfect straight-line motion, and vice versa.
