This is a public lecture I gave at Fermilab on April 6, 2011 as part of the Physics for Everyone lecture series. The native format is .pptx produced on a Mac, and this is the only platform where I can guarantee that the many animations and overlays will work properly. The .pdf is a flat version of the talk and quite a bit is lost relative to the power point version. There is a video of the original presentation available online at:
