A bit of drama followed this broadcast. Soon after it aired April 19, 2009, CBS pulled the popular video from it's Web site without explanation. Conspiracy theorists mobilized; we investigated. Turns out that the American Physical Society protested the reference to its organization.
In response, CBS took the video off-line for about 24 hours. The network edited the offending segment, removed the reference to APS and put the revised video back online at a new Web address. Mysteriously, CBS put the original version back online sometime before May 24.
