MIT looks to reach an epic milestone soon: By the end of the year, its entire curriculum should be available online for free. Scholars and amateurs are coming in droves; this month, the site could receive 1.5 million visits. "It's exceeded our expectations," said Anne Margulies, head of MIT’s online curriculum program, OpenCourseWare. MIT began putting courses online in 2001; more than 1,500 are already available, and all of its 1,800 courses should be posted by the end of this year. So far, the most popular online course has been an introduction to electrical engineering, Margulies said, but visitors to the site can also school themselves on such subjects as cell-matrix mechanics, holographic imaging, hip-hop, and "How to Make (Almost) Anything."
