Stretching over 20000 km, the Greenwich meridian covers almost 13000 km of oceans and only 7000 km of land. From north to south, the 0 meridian passes the icebergs of the Arctic, the mild and mediterranean climates of Europe, the African deserts and tropics, the south Atlantic to end again at the south pole. The largest part of the meridian runs through deserted areas where nobody lives, but what cultural richness and diversity can be found in the populated areas! With this beautiful photography book, Steven Weinberg takes the reader on a voyage along the famous Greenwich meridian.
