Jacques Charles François Sturm, the French-Swiss mathematician born on this day in 1803, is being commemorated for Sturm's Theorem, which counts the real roots of a polynomial. Sturm also collaborated with physicist Daniel Colladon on the first measurement of the speed of sound in water, carried out on Lake Geneva in 1826. Posts marking the anniversary highlight both achievements and his connection to sites in France and Switzerland.
