Thermodynamics, conceptual artwork. Thermodynamics is the study of the macroscopic properties of a system (such as heat and pressure) using the statistics of the motion of the particles in the system. Here, the spheres could represent hot (red) and cold (blue) gas molecules, mixing between hot and cold systems (red and blue squares, top and bottom).
