lisa randall, she is a theoretical physicist at harvard talking about new discoveries based on the higgs boson theory. >> one of the things that was so interesting about this discovery is it didn't have to look like this. there are other types of particles, other sectors that can make the higgs megaisim in work. the higgs boson is in some sense the simpleest possibility but it could be more complicated and that's one of the reasons that the experiments are now studying in detail the properties of the higgs boson, to find out is it really the simplest example that implement this is mechanism or is it something richer and deeper that sheds light on what goes beyond? >> rose: politics, foreign policy, and physics when we continue. , with governor romney delivered a major foreign policy speech earlier today at the virginia military institute. he highlighted areas of contrast with president obama. >> we can't support our friends and defeat our enemies in the middle east when our words are not backed up by deeds. when our defense spending is being arbitrarily and deeply cut. when we have no trade ag
