The Rose Center for Earth and Space at the American Museum of Natural History has sponsored a video contest, asking participants to express in two minutes or less how science has moved them or impacted their lives. These contests are great ways to let an “audience” become real participants in a process, and have some fun along the way.
Sadly the deadline is passed, so we can’t encourage you to contribute, but you can check out the entries. Here’s a video about the LHC, by Luke Cahill. (I’m using YouTube’s new “iframe” embedding scheme; let me know if it doesn’t work.)
