I&#8217;ll label them 1 and 2, though it&#8217;s really a chicken-and-egg thing. This is the way physics works, simplified:<\/p>\n<p>1. The experimental results produce data which suggest ways old theories could be refined, replaced, or strengthened.<br \/>\n2. The new theoretical descriptions and predictions suggest new experiments to test the accuracy of those theories. Go back to step 1.<\/p>\n<p>And recursively the theories become better and better approximations to reality. Some theories like QED and general relativity are literally perfect as far as we can tell, though most physicists expect that (say) general relativity will eventually require changes at very high energy.&quot;<\/p><\/div>\n<div class=\"delicious-tags\">(tags: <a href=\"http:\/\/delicious.com\/orzelc\/science\">science<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/physics\">physics<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/academia\">academia<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/philosophy\">philosophy<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/built-on-facts\">built-on-facts<\/a>)<\/div>\n<\/li>\n<li>\n<div class=\"delicious-link\"><a href=\"http:\/\/blogs.scienceforums.net\/swansont\/archives\/2215\">Swans on Tea \u00c2\u00bb The Groaning Grid<\/a><\/div>\n<div class=\"delicious-extended\">&quot;I remember when I was discussing a story about fast-charging batteries with someone that there was the conjecture that this was the hurdle to getting electric cars on the road.

Ideally one does good calorimetry and can measure the amount of energy that comes out of the cell in the form of heat, vs. the amount of energy put in in the form of integrated electrochemical current times voltage. The claim is that in some such experiments, the inferred amount of energy out is much larger than the electrical energy in. This is &quot;excess heat&quot;.<\/p>\n<p>So, what&#8217;s the problem? Well, there are several issues.&quot;<\/p><\/div>\n<div class=\"delicious-tags\">(tags: <a href=\"http:\/\/delicious.com\/orzelc\/science\">science<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/physics\">physics<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/blogs\">blogs<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/energy\">energy<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/chemistry\">chemistry<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/natelson\">natelson<\/a>)<\/div>\n<\/li>\n<li>\n<div class=\"delicious-link\"><a href=\"http:\/\/www.gocomics.com\/foxtrot\/2009\/04\/19\/\">Fox Trot \u00e2\u0080\u0094 Gocomics.com: Comics, editorial cartoons, email comics, comic strips<\/a><\/div>\n<div class=\"delicious-extended\">&quot;Think of it as a challenge&#8230;&quot;<\/div>\n<div class=\"delicious-tags\">(tags: <a href=\"http:\/\/delicious.com\/orzelc\/math\">math<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/comics\">comics<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/silly\">silly<\/a>)<\/div>\n<\/li>\n<li>\n<div class=\"delicious-link\"><a href=\"http:\/\/www.washingtonmonthly.com\/archives\/individual\/2009_04\/017812.php\">The Washington Monthly<\/a><\/div>\n<div class=\"delicious-extended\">&quot;[T]he KSM example seems to put the practical question to rest altogether.
