Imagine air molecules in a room. They move around with all possible velocities in all directions. Attaining the exact knowledge of these trajectories is a daunting and an unrealistic task. Statistical ...

We discuss the problem of defining (nonequilibrium) entropy in terms of the concepts of mechanics and of reconciling its monotonic increase with the Hamiltonian evolution of the dynamical system. This ...

For a technical scientific term, entropy is pretty popular. I mean, it was the title of an episode of Buffy the Vampire Slayer, after all. Search the Internet for “entropy” quotes and you’ll find them ...

The fields of thermodynamic formalism and ergodic theory provide a rigorous mathematical framework for understanding complex dynamical systems by recasting ideas from statistical mechanics in a ...
