MSNBC.com: On Monday, President Obama hosted a science fair at the White House, at which 11 award-winning science projects were displayed. Obama is working to promote science and math education, because he is concerned that the US is being outpaced by other countries. The event kicked off a week of science-centric activity in Washington, DC, as part of the USA Science and Engineering Festival, which culminates 2324 October on the National Mall. Obama also used the occasion to announce his upcoming 8 December appearance on the Discovery Channel program MythBusters, which uses science to uncover the truth behind urban legends.
