Nuremberg was the centre of astronomical craft in the 16th century, Regiomontanus explained why he decided to settle there: “not only on account of the availability of instruments, particularly the astronomical instruments on which the entire science of the heavens is based, but also on account of the very great ease of all sorts of communication with learned men living everywhere, since this place is regarded as the centre of Europe because of the journeys of the merchants.” mhs oxford

Submarine Cable Map 2014
A map put together by TeleGeography displays where all the undersea fibre-optic telecommunication cables are and who they connect to … in other words, a map of the physical internet:
The map depicts routes of 263 in-service and 22 planned undersea cables. Each country is colored according to how many international submarine cable system links are connected there. Capital cities and the location and direction of 44 cable vessels (as of December 6, 2013) are also provided.
The map provides detailed information about cable landing stations in key regions including Hawaii, Southern Florida, New York, New Jersey, Cornwall, Singapore, Hong Kong, Tokyo, and Sydney.
The map is available for purchase at TeleGeography. You can find out more about the map here
