At the turn of the century, a new approach to science gradually emerged. In this “information approach”, science is not a description of world in itself, but a coding of the information scientists have about the world. This approach was born inside statistical mechanics from the effort of giving a microscopic interpretation of entropy. […]
In this paper we present a discussion of the first and the second law of thermodynamics based on the balance equation for energy and entropy. In the second part we illustrate some didactical advantages of this approach. […]
Different versions of the two slits experiment are investigated, pointing out the peculiar difficulties of its didactic presentation, and the conceptual misunderstandings that a superficial reading of the experience can lead to. […]
In this paper we start from the analysis of some problems leading to the finite difference equation: (delta f / delta x) = k * f(x) + a , f(0) = f0, k and a being constants, related to the differential equation: (df / dx) = k *f(x) + a. […]
