If you shoot some neutrons at this, you can get it to break into pieces. The cool part is that the mass of all these pieces does not add up to 235 u. This is the essence of nuclear fission where the missing mass becomes energy (E = mc2).<\/p>\n<p>If college is like uranium, then the classes the student takes are like the pieces that uranium can break into. A college experience is more than the sum of the classes that make up that degree. And this is where online universities have a problem. I like to think of college and universities as a community of learners (and I am one of those learners). College is more of an experience and a time to learn to think about things in different ways. &#8220;<\/p><\/div>\n<div class=\"delicious-tags\">(tags: <a href=\"http:\/\/delicious.com\/orzelc\/education\">education<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/academia\">academia<\/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\/dot-physics\">dot-physics<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/culture\">culture<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/society\">society<\/a>)<\/div>\n<\/li>\n<li>\n<div class=\"delicious-link\"><a href=\"http:\/\/suburbdad.blogspot.com\/2010\/02\/thoughts-on-alabama-shooting.html\">Confessions of a Community College Dean: Thoughts on the Alabama Shooting<\/a><\/div>\n<div class=\"delicious-extended\">&#8220;From what is known now, this case doesn&#8217;t provide another example for some ideological battle.
