September 27th marks 100 years since Albert Einstein submitted a paper which introduced his famous equation: E = mc2.
I heard about it on NPR today, and thought I would include a link to their coverage of Einstein.
Even better is some major coverage on the NOVA site from PBS. The site is a companion to their series: Einstein's Big Idea. One of the articles on the PBS site lets you listen to 10 top physicists explain the equation.
