Summary
[edit]Description1 o'clock gun map (5354511937).png |
today was the 150th anniversary of the <a href="http://en.wikipedia.org/wiki/Edinburgh_Castle#One_O.27Clock_Gun" rel="nofollow">One O'Clock Gun</a> at Edinburgh Castle. This was inspired by the original <a href="http://www.edinphoto.org.uk/1_map_2/1_map_edinburgh_1861_time-gun_-_whole_map.htm#map" rel="nofollow">One o'clock gun map</a> which shows how long the sound takes to reach different parts of the city. Each circle represents 1 second. It's surprising how slow sound travels when you look at the scale of a city - it takes about 10 seconds for the sound wave to reach Leith. Map via <a href="http://www.openstreetmap.org/" rel="nofollow">OpenStreetMap</a> This is a screencap, there is a real-time animated version <a href="http://www.openprocessing.org/visuals/?visualID=14097" rel="nofollow">here on OpenProcessing</a> (requires Java) |
