This mural refers to the dual nature of light-- it can behave as a wave or a particle, so the mural can be read either way. Schrodinger (ex: Schrodinger's cat paradox), Heisenberg (Heisenberg Uncertainty principle for electrons), Einstein (E=mc^2, energy and mass are the same thing in different forms), Plank (Planck's constant, h= 6.63* 10^-34 J*sec), and de Broglie (discovered small particles could also behave like waves) are all famous scientists.
