... to define an important vector associated with this scalar field. The gradient (denoted as ∇f) is defined such that the dot product of it and a differential displacement vector gives the total differential: df d f ≡ ∇ r . EXAMPLE: ... Brenner. ♥ The word “dyad” comes from Greek: “dy” means two while “ad” means adjacent. Thus the name dyad refers to the way in which this produ...
