There is a fairly fasbionable current of thought that bolds that the use of advanced mathematics is of little real use in physics， and goes sometimes as far as to say that knowing convinced that matbematics is stikll a parecious source of insight， not for students of physics， but also for researchers.Many only see mathematics as a tool-and of course， it is part a tool， but they should be reminded that， as Galileo said， the book of Nature is written in give examples that knowing mathematics provides the means to understand precise physical notions， to use them more easily， to establish them on a sure foundation， and even more importantly， to discover new ones.
