Don't be alarmed if you happen to hear indecipherable nerd babble echoing off the fluorescent bathed hallways of ASU's Bateman Physical Science building. That's because Physics and Astronomy graduate students are high off cool neutrons and totally hot electrons during the department's free open house. Every last Friday of the month from September through November and February through April, the public can participate in high-energy physics demonstrations and attend presentations on cosmic hot topics ranging from the search for new planets to trans-Neptunian solar system discoveries. After receiving tutelage on light prisms and cosmic energy fields, stroll out to the fifth-floor observation deck, where up to 10 portable eight-inch Schmidt-Cassegrain reflector telescopes are zoomed on eye-popping Milky Way stars, moons, and planets. Pray for clear skies and commence stargazing, space cadet.
