Contributions of George J. Papadopoulos
  I review some of the scientific work of George Papadopoulos in the context of the Greek cultural tradition and modern theoretical physics. The main emphasis is on his works on path integrals and their applications. The review is closed by an excursus on the polaron physics, where the path-integral approach has been proven to be a method of excellence.
