Maree: che cosa Newton deve a De Dominis e Galileo
In the 17th century De Dominis, Galilei and Newton proposed three different theories on the tides. Eventually Newton’s theory, some aspects of which recall the other two, was adopted. This paper proposes a school activity in which the three theories are compared. The activity allows the pupils, while revisiting Newtonian mechanics, to see how it differs from the ideas of Galilei.
