Legacy
In France, the fundamental theorem of algebra is known as the d'Alembert/Gauss theorem (an error in d'Alembert's proof was caught by Gauss).
He also created his ratio test, a test to see if a series converges.
The D'Alembert operator, which first arose in D'Alembert's analysis of vibrating strings, plays an important role in modern theoretical physics.
While he made great strides in mathematics and physics, d'Alembert is also famously known for incorrectly arguing in Croix ou Pile that the probability of a coin landing heads increased for every time that it came up tails. In gambling, the strategy of decreasing one's bet the more one wins and increasing one's bet the more one loses is therefore called the D'Alembert system, a type of martingale.
