Physicist
Ludwig Boltzmann
Explained heat and entropy in terms of atoms while many of his colleagues doubted atoms existed. He hanged himself on holiday in 1906; the equation is on his gravestone.
Ludwig Eduard Boltzmann was an Austrian mathematician and theoretical physicist. His greatest achievements were the development of statistical mechanics and the statistical explanation of the second law of thermodynamics. In 1877, he provided the current definition of entropy, where Ω is the number of microstates whose energy equals the system's energy, interpreted as a measure of the statistical disorder of a system. Max Planck named the constant kB the Boltzmann constant.
