Dim and save
Professor of Engineering Sung Hu explained the energy saving capability of dimmer switches on the KPIX-TV News segment "Good Question" on Jan. 19. "In most cases, yes (you are saving energy when you dim lights), because modern dimmer switches are built using electronic switches called a TRIAC," Hu said. TRIAC switches turn the light on and off rapidly to give the illusion of a dimmer light. "It's just like watching a movie," he added.

Historic discrimination
Political Science Lecturer David Lee contributed to a Jan. 18 Los Angeles Times report on the Bay Area's history of discrimination and the recent ascension to mayor of two Chinese Americans. "There were institutional barriers put in place by government to prevent the very thing we're seeing now, the true political empowerment of this community," Lee said, referring to Gold Rush-era discriminatory policies that culminated with the Chinese Exclusion Act of 1882.
