There is no question that Feynman diagrams have changed the way physicists think about particle physics. But vector calculus has an even greater reach as the mathematical foundation of much of ...

are used to describe situations where several forces act on an object. Vector diagrams are used to resolve (break down) a single force into two forces acting at right angles to each other.

The sum of these two forces can be found using a vector diagram. The two forces are represented by the adjacent sides of a parallelogram, the lengths of the sizes being proportional to the size of ...

NOT many years ago a certain type of journalist used to compare and contrast the theorist and the practical man, to the demolition of the former and the apotheosis of the latter. Fortunately, such ...
