    "abstract": "We report on a very simple and inexpensive method for determining the speed\nof an electrical wave in a transmission line. The method consists of analyzing\nthe roundtrip time for ethernet packets between two computers. It involves\nminimal construction, straightforward mathematics and displays the usefulness\nof stochastic resonance in signal recovery. Using basic electrical properties\nof category-five cable students may use their measurements to determine the\nspeed of light in the vacuum to within a few percent.",
