In late April, the APS LaserFest outreach team participated in the Cambridge Science Festival in Cambridge, Massachusetts. Over 3000 students had the opportunity to sample a variety of giveaways and demonstrations illustrating some of the unique features of the laser. In the picture, APS Outreach Specialist Chris Discenza (right) is busy keeping up with traffic at the LaserFest table, while a passerby ponders the astrophysical uses of lasers. The poster she's looking at is one of three with teaser questions that APS created for LaserFest. Those interested can request copies of the posters, as well as find the answers to the questions, by visiting either PhysicsCentral (www.physicscentral.com) or the LaserFest website (www.laserfest.org).
