Re: vector components and notation

A minor quibble here - aren't projections the result of the dot product of the
vector in question with the basis vectors - which makes them scalars (the A_x
in your exposition)? We seem to be in the position of being separated by a
common language :-)

|A_x| = a positive scalar, the length of the component vector
