Introduction to Statistical Methods,roblem to analyze the main features of binomial and Gaussian distributions, to define mean (expected) values and standard deviations, and to investigate the role of large numbers. The simplest versions of the random walk problem are already related to models of physical interest, suggested by the di

Phonons and Magnons,ion of the elastic vibrations of a crystalline lattice. Magnons are quasi-particles associated with the elementary magnetic excitations above a ferromagnetic ground state (although there are magnons associated with antiferromagnetic and even more complex magnetic orderings).
