| General Information: |
| A mathematician known to students of calculus and of heat who published a paper on the bowed string |
| in which he recognized the need to consider two parts of a period of vibration, sticking and slipping. He |
| derided the idea that the vibrations of the bowed string are caused by the plucking action of barbs on the |
| bow hair -- a concept that still plagues us. He failed to understand a fact later recognized by Helmholtz |
| that wave propagation along the string is not instantaneous, but occurs with finite velocity, thus freeing |
| the string from the bow not as a result of increase in stress between the two, but because the sharp kink |
| in the string has suddenly returned after reflection from the nut. |
