The result of finding the gradient of a scalar field is a vector, a quantity that has both magnitude and direction! More specifically, it is a vector function -- a function that gives us back a vector when we give it a position, i.e. a particular \(\langle x, y, z\rangle\) .
Franco Zeffirelli's Romeo and Juliet is a lovely, sensitive, friendly popularization of the playthe lovers, Leonard Whiting and Olivia Hussey, as young and full of life as they ought to be, Italy of its time there intact, a lot made of the relationship between Romeo and Mercutio, beautifully played by John McEnery.
Also, at the end of the play he fights and kills Paris with a sword. Likely Romeo was at least 18 and quite possibly in his early 20's. Shakespeare probably gloated over this discussion 400 years ago. From dialogue in the play, we know that Juliet is 13 years old. While we know that romeo is older, we have no reference to indicate how much older he is. His age other than older than Juliet is all that can be determined.
