The American Physical Society represents some 48,000 physicists, and most of our work centers on scientific meetings and publications-the primary ways that physicists communicate with each other. With PhysicsCentral, we communicate the excitement and importance of physics to everyone. We invite you to visit our site every week to find out how physics is part of your world. We'll answer your questions on how things work and keep you informed with daily updates on physics in the news. We'll describe the latest research and the people who are doing it and, if you want more, where to go on the web. So stick with us.
