Palle di neve ed equazioni differenziali
Mathematics teaching in recent decades has undergone radical changes: the purpose is no longer to be able to meticulously carry out long and demanding calculations; today, with the advent of computers, socalled "design" capabilities have become much more relevant, such as modeling real problems, knowing how to use various types of languages, interpreting statistical data and controlling the reasonableness of the calculations made using a computer. Specifically, this article presents a problem regarding the speed of melting a snowball; various models are presented describing the phenomenon and, for each of them, the solution of the relative differential equation is presented.
