Pierre Curie
JAN 01 1903
A 1903 portrait of Pierre Curie. His 1895 doctoral thesis measured how the magnetic properties of substances change with temperature and produced what is now Curie's law - the result that separated diamagnetism, which barely cares about temperature, from paramagnetism, which does. Small at 280x396.
