| In Mathematics, there is no such concept as distance |

| I'm trying to measure the length of my land. I think it is 843 jugs long! |
Fig. 1 Math versus Physics |

| In Physics, length and distance are conceptually qualitative and static. We can freeze length and distance in a single photograph. Both length and distance invoke TWO surfaces. We may tentatively draw length and distance with solid lines to indicate that the image invokes a single frame of the movie: a photograph. We draw TWO arrowheads at the ends of each of these lines to indicate that length and distance extend between TWO surfaces. In this manner we don't lose sight of the true meanings of these avatars and do not confuse them for the concepts they represent. |
| In Math, length and distance are the distances traveled by the leading edge of a tape, the arm of a clock, or another device used in the dynamic measurement process. The mathematician is comparing the final location of ONE object against its now imaginary starting location. The lengths and distances of Mathematics are expressed in terms of predefined units. We draw distance-traveled with dotted, dashed, or segmented lines to indicate that we are pondering a movie of a single object. The dots and dashes represent frames of the film. We draw ONE arrowhead at the end of the line to indicate that only ONE object is involved. |

| In Physics, distance is the (static) separation between two surfaces. You can only visualize this separation laterally (horizontal distance).In contrast, the distance-traveled of Mathematics is a movie. The kinetic distance of Mathema- tics consists of a stack of cards that an observer fans in order to visualize motion and can only be imagined in the direction of travel. Conceptually, distance- traveled is surrealistic because the mathematician is attempting to sew from the present location of the object to its imaginary initial location through a stack of frames comprising the movie. The object at its initial location requires memory. There is no real object there any more. The mathematical definition is unscientific because it cannot be used consistently. |


| You see, Bill, at Cambridge, we measure length with a clock. |
