How many nuclear explosions do you think there have been on planet Earth? Did you instantly say "two?" Did you then rethink and say, "Oh, I forgot about those tests...there may have been a few more."
Would you believe 2053? That's how insane the human race is. The graphic at the URL below is fascinating. It's by Japanese artist Isao Hashimoto, who plots each of these explosions on a map of the world, each one indicated by a beep, with other bleeps and bloops counting off the months and years. The result is a revealing musical and visual insight into a mindset that can best be described as "Guys blowing things up, just because they can." http://www.wired.co.uk/news/archive/2010-07/6/japanese-artist-nuclear-weapons
