Thanks martin_fierro. I think this has been the best couple of weeks for the X-Planets and String Theory lists in quite some time.

Thanks martin_fierro. There's even a GGG connection: In practice, the very first calculation of the circumference of the Earth -- dating to the 3rd Century B.C. -- used a very similar method, again reliant on simple geometry. Image credit: NOAA Ocean Service Education's history of geodesy. Just adding to the catalog, not sending a general distribution. To all -- please ping me to other topics which are appropriate for the GGG list.
