In May 1889, Irish physicist George Francis FitzGerald published a short paper proposing that moving physical objects contract along their line of motion by factor sqrt(1 - v^2/c^2), explaining Michelson-Morley.

In 1889, 25-year-old German physical chemist Walther Nernst derived the Nernst Equation (E = E° - (RT/nF) ln Q), connecting electrochemical cell voltage directly to ion activities and thermodynamics.
