Abstract

Carlo Cercignani was known all over the world for his works on the Boltzmann equation and on kinetic theory. There was however another aspect of his scientific life, which is not much known. Namely, his interest for the foundations of physics, in particular for the possibility of understanding quantum mechanics through classical mechanics, which he shared with several people in Milan. A review of such researches is given here, together with some personal recollections of him.
