ABSTRACT
The authors’ current approach is never more than a means. Beyond it lies another goal, which is itself only a means toward a higher goal. At one company, sandpaper was used to smooth the rough surfaces inevitably remaining on pressure-formed ebonite switch holders. Ebonite is hard and brittle, so that whereas rubbing it too hard could damage the material, rubbing it lightly took a great deal of time. Steel pellets were tried first, but they produced defects in the form of rounded edges. Plastic beads were tried next, but this time the abrasive material wore down too quickly. The outer hull of each boat was made of a plastic material, and several layers of fiberglass attached with adhesives to the interior made the boats both strong and light. In fact, however, a mean value is nothing more than the average of actual values and is not in any way an expression of fact.
