- As a math student I have to protest ;-) A physics book is probably not the
- right place to look up such concepts. A scalar IS a vector (in a one-
- dimensional vector space). It's just a matter of view-point. The vector
- definition with direction you're refering to is just a useful special
- case. Q.e.d.
