Timeline of states of matter and phase transitions 1895 - Pierre Curie discovers that induced magnetization is proportional to magnetic field strength 1911 - Heike Kamerlingh Onnes discovers superconductivity 1912 - Pieter Debye[?] derives the T-cubed law for the low temperature heat capacity of a nonmetallic solid 1925 - Ernst Ising[?] presents the solution to the one-dimensional Ising model and models ferromagnetism as a cooperative spin phenomenon 1933 - Walter Meissner[?] and R. Ochsenfeld[?] discover perfect superconducting diamagnetism 1942 - Hannes Alfven[?] predicts magnetohydrodynamic waves in plasmas 1944 - Lars Onsager publishes the exact solution to the two-dimensional Ising model 1957 - John Bardeen, Leon Cooper[?], and Robert Schrieffer[?] develop the BCS theory of superconductivity 1958 - Rudolf Mossbauer[?] finds the Mossbauer crystal recoil effect 1972 - Douglas Osheroff[?], Robert Richardson[?], and David Lee[?] discover that helium-3 can become a superfluid 1974 - Kenneth Wilson[?] develops the renormalization group technique for treating phase transitions 1987 - Alex Muller[?] and Georg Bednorz[?] discover high critical temperature ceramic superconductors
