(*) piezoelectricity.
At the main site of 2008 Minnesota Open, this scientist was the third part of a bonus in that tournament's first round. This scientist invented the crystal oscillator, and his name is sometimes attached to The Landau-Lifshitz-Gilbert Equation. (+) This scientist made important research advances in paramagnetism and diamagnetism, and along with Pierre Curie, whom he co-names a law with, he studied  (*) piezoelectricity. Although this man is not Albert Einstein, one of this physicist's ideas is similar to a doubly eponymous equation that models Brownian Motion, called the Fokker-Planck Equation. For ten points, name this French physicist who created the Twin Paradox, a physicist with a namesake formula, function, law, and equation.
