"Danger, Will Robinson!" "Lost in Space" will be showing at Gallagher Theatre tonight at 7:30p.m. and 10:00p.m. Time travel, teenage love, and high-tech robots are all yours (on screen) for only $2.50.

Bugs! The UA Entomology Department is presenting a seminar today in room 230 of the Marley Building. Daniel J. Funk, post-doctoral fellow in the UA Center for Insect Science, will be giving you the lowdown on "Geographical Variation and Sympatric Differentiation in the Host Specificity of Some Insect Herbivores" at 4:00p.m. Refreshments will be served at 3:45p.m. in the breezeway for those who arrive early. Come see where your childhood bug collection could have taken you.

Tom L. Nilson, of the Sub Millimeter Telescope Observatory, is ready to change your ideas about stargazing today at 4:00p.m. "Dense Molecular Cores in Orion" will be discussed in room N210 of the Steward Observatory; stop by at 3:30 for complimentary refreshments. This lecture is being offered as part of the Joint Colloquium headed by NOAO, KPNO, NSO, NRAO, and the Steward Observatory. Contact Pat Breyfogle at 318-8115 for more information.

Try as we might, humans just don't seem to be able to grasp the concept of "infinity." Well, most of us don't. At least in the mathematical sense. Alas, there exists an enlightened individual ready and willing to help us through this mind-boggling idea- namely David Lovelock. Tonight, from 7:00p.m. to 8:30p.m., anyone who's ever been confronted with terms like "Fourier series," "Taylor expansion," or "power series" (or, anyone who has just read them here and consequently cannot sleep tonight until he or she learns the definitions) is invited to attend a lecture concerning the infinite series. Though this is, according to the release, perhaps the most difficult math in the world (i.e., "If crowds scare you, you'll have no problem with this lecture"), its got some pretty widespread applications. Take your seat in room 201 of the Physics and Atmospheric Sciences Building and leave your notions of parameters at home.

This semester, the Department of Anthropology and the Arizona State Museum are cosponsoring the New Directions in Southwestern Anthropology Lecture Series. All are welcome to come hear the first speaker in the series, Gary Nabhan, give his views on "Reptiles as Resources, Curses, and Cures: Seri Traditional Knowledge of Wildlife." The lecture will focus on the interactions and relationships between the Seri and the wildlife of western and coastal Sonora, and will be held in Economics room 110 at 7:30p.m. All this talk about desert living is sure to make you thirsty, so join the crowd afterward in the Arizona State Museum for a reception. Contact Suzanne Fish at 621-2556 for details.

Free science movies are now being shown weekly by the Physics Department. Students, faculty, and the community are invited to attend. This semester's series is Carl Sagan's "Cosmos." Showtimes are Fridays from 11:00a.m. to noon in Physics and Atmospheric Sciences room 201. Questions? Call Larry Hoffman at 621-6826 for answers.
