Reliable sources tell Keeping Track that Science A-20, "From Alchemy to Elementary Physics," recently moved to Saunders Theater after smaller sites were jammed with up to 500 students.

Instructor Sheldon L. Glashow, Higgins Professor's of Physics, attributed the popularity of his course (and "the presence of the football team") to his 1980 Nobel Prize of Physics, and the legendary 1.7 workload rating by the Curriculum Evaluation Guide.

Now, however, some of the gut-seekers have found the course's problem sets unexpectedly difficult, and complain that lectures don't cover all the problem set material, thus requiring outside reading or a strong physics background.

Teaching assistants in the course, which has higher enrollment than all but Soc Anal 10 this fall, disagree. "Just glancing over the problems, it seems to me that they don't require a hell of a lot of math," commented t.a. Jairam Lingappa.
