My friends, during last night’s presidential debate, McCain took That One to task for approving funding for an “overhead projector.” Howard Covitz, who used to work at Chicago’s Adler Planetarium, prepared this helpful graphic for McCain to show the difference between an overhead projector and a planetarium projector.

A bit late on this, but McCain has been using the “projector” in his stump speech, so it would be worthwhile to mention the real story behind the projector and the people who try to get other, younger, people interested in science.

UPDATE: Another excellent article on the topic.
