Since 1927 we have been serving our members and the public in all aspects of amateur astronomy. If you want to keep up with the space program, learn what's happening at the frontiers of astronomical research, or just appreciate the beauty of the night sky, we can help. We sponsor lectures at the Museum of Natural History by leading researchers, provide economical classes in astronomy to members and hold a seminar on Recent Advances in Astronomy twice a month. We also host observing sessions at several locations in the New York metropolitan area. Stop by and look through members' telescopes. If you're thinking of getting a telescope or binoculars, you can get advice from experienced stargazers. The club also holds a monthly Observers Group meeting, where members can discuss equipment, observing techniques, recent observations and upcoming celestial events. Check out what's in the sky this month. The Amateur Astronomers Association produces a monthly newsletter, Eyepiece, containing several articles of interest. Be sure to take a look at some of our members' photos and articles.

Logic is an ancient discipline that has undergone striking modern developments through the introduction of rigorous formal methods, stimulated largely by foundational problems in mathematics. "Symbolic logic" is a term intended to encompass the entire field of logical inquiry, undertaken in this modern spirit. The Association for Symbolic Logic is an international organization supporting research and critical studies in logic. Its primary function is to provide an effective forum for the presentation, publication, and critical discussion of scholarly work in this area of inquiry.

The Astronomical Society of the Pacific was founded in 1889 by a group of Northern California professional and amateur astronomers after joining together to view a rare total solar eclipse. The ASP's earliest purpose was to disseminate astronomical information - a mission which has flourished with astronomers' inexhaustible exploration of the universe. The ASP has become the largest general astronomy society in the world, with members from over 70 nations. The ASP Board of Directors is comprised of members of the astronomy, educational, and amateur communities.
