VectorsMay 16, 2009
Ordinary vectors can be added, subtracted, reversed, multiplied, scaled. They are more than small lines and arrowheads on notebook pages. They represent more than a simple equation. Sometimes they measure acceleration toward a point of intersection.
They might represent force, or velocity, or a southbound train accelerating to 70 miles per hour. These things, after all, can be measured and documented, tracked and analyzed. There is direction. There is magnitude. And even when logic has dissapated, there is no vector without sense.
