Accomplishments of the Curies
Before Pierre Curie married Marie, he was focused mainly on his studies of crystallography. Through work with his brother, their work led to the discovery of piezoelectricity, the electric polarization due to expansion or compression of crystals in a certain direction. They also learned that when an electric field is applied, the crystals are compressed and with alternating currents, crystals can vibrate at high frequencies. This is the basis of modern stereo equipment.The brothers also invented the piezoelectric quartz balance, paving the way for modern quartz watches and radio transmitters. During his years as a college proffesor, he also demonstrated that the magnetism of a substance changes at certain temperature. This is now known as the "Curie Point." The relation between magnetism and temperature would become known as "Curie's Law"
