This leaves out North Korea&#8217;s two alleged nuclear tests in this past decade (the legitimacy of both of which is not 100% clear).<\/p>\n<p>Each nation gets a blip and a flashing dot on the map whenever they detonate a nuclear weapon, with a running tally kept on the top and bottom bars of the screen. Hashimoto, who began the project in 2003, says that he created it with the goal of showing&#8221;the fear and folly of nuclear weapons.&#8221; It starts really slow &#8212; if you want to see real action, skip ahead to 1962 or so &#8212; but the buildup becomes overwhelming.&#8221;<\/p><\/div>\n<div class=\"delicious-tags\">(tags: <a href=\"http:\/\/www.delicious.com\/orzelc\/history\">history<\/a> <a href=\"http:\/\/www.delicious.com\/orzelc\/art\">art<\/a> <a href=\"http:\/\/www.delicious.com\/orzelc\/war\">war<\/a> <a href=\"http:\/\/www.delicious.com\/orzelc\/politics\">politics<\/a> <a href=\"http:\/\/www.delicious.com\/orzelc\/nuclear\">nuclear<\/a> <a href=\"http:\/\/www.delicious.com\/orzelc\/video\">video<\/a> <a href=\"http:\/\/www.delicious.com\/orzelc\/world\">world<\/a>)<\/div>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Polson High School students use primitive bows to study physics &#8220;It&#8217;s one thing to put Montana&#8217;s Indian Education for All Act to work in a social studies classroom.
