why a vector? also a bar means average, vectors are either hats or arrows or bold fonts

vector notation can be a bar when handwritten, people often omit the arrow

velocity, position and amplitude are vector magnitudes

>bar means average
i like angle brackets much better for averages since they jive with the angle bracket notation of inner products

Halmos wrote it without a bold typography, and without arrows on top, just using letters v and u and the like (with perhaps an italic font but which he used for every other letter)

>amplitude isnt a vector
it can be, now I think about it, I think it is more standard to multiply by a unit vector, but is there any reason amplitude cannot be a vector?
