ResourceOn This Day – Jul 21 : Rudolph Marcus was born
He developed electron transfer theory, which describes the thermodynamics and kinetics of how electrons are transferred between chemicals during a reaction. The theory helps to explain reactions such as oxidation, photosynthesis and cell metabolism.

ResourceOn This Day – Sep 05 : Ludwig Boltzmann died
He was best known for his kinetic theory of gas particles. His statistical methods explained how properties of atoms could predict the visible properties such as thermal conductivity and diffusion. This helped to bridge the gap between the thermodynamics of a large system and at a molecular level.

ResourceOn This Day – Jan 02 : Rudolf Clausius was born
He was one of the central founders of thermodynamics. He introduced the concept of entropy and stated the second law of thermodynamics for the first time. He also introduced concepts of kinetic theory to explain motion of gas molecules, in particular the mean free path of particles.
