    "abstract": "The traceroute utility on any computer connected to the Internet can be used\nto record the roundtrip time for small Internet packets between major Internet\ntraffic hubs. Some of the routes include transmission over transoceanic fiber\noptic cable. We report on traceroute\u0027s use by students to quickly and easily\nestimate the size of the Earth. This is an inexpensive way to involve\nintroductory physics students in a hands-on use of scientific notation and to\nteach them about systematics in data.",
