Every Londoner has used it, but has everyone really seen it? The old map is looking a bit dusty. Perhaps its time for Geographic precision or maybe 3D projection. If we add bicycles to the map, is it still an underground? ]]> Fri, 13 Aug 2010 05:47:00 -0700 http://www.metafilter.com/mefi/94713 http://www.youtube.com/watch?v=ocj4-y6sc9o&feature=youtube_gdata ]]> Mon, 07 Dec 2009 18:21:00 -0700 http://www.youtube.com/watch?v=ocj4-y6sc9o&feature=youtube_gdata http://www.newscientist.com/special/beyond-space-and-time We don't have any trouble coping with three dimensions – or four at a pinch. The 3D world of solid objects and limitless space is something we accept with scarcely a second thought. Time, the fourth dimension, gets a little trickier. But it's when we start to explore worlds that embody more – or indeed fewer – dimensions that things get really tough. These exotic worlds might be daunting, but they matter. String theory, our best guess yet at a theory of everything, doesn't seem to work with fewer than 10 dimensions. Some strange and useful properties of solids, such… ]]> Fri, 18 Sep 2009 01:01:00 -0700 http://www.newscientist.com/special/beyond-space-and-time http://a.aaaarg.org/text/3791/impossibility-drawing-map-empire-scale-1-1 by Umberto Eco ]]> Tue, 08 Sep 2009 09:15:00 -0700 http://a.aaaarg.org/text/3791/impossibility-drawing-map-empire-scale-1-1
