Macroscopic bosons among us
In the spring of 1995, I was serving on an academic "Planning and Priorities" committee, and some of my fellow committee-members became concerned that there were too many graduate courses, and that this was a symptom of inadequate focus on undergraduate education. I agreed on both counts, though I also felt that an excessive number of grad courses was — and is — generally a bad thing for graduate programs as well.
Anyhow, I became curious about what the distribution of course registrations was actually like. The following note, unearthed after 17 years and recycled as a Language Log post, was the result. I fished it out of the midden-heap of old email because of its marginal relevance to the July 4 announcement from CERN. It turns out that graduate students, like the Higgs particle, are bosons — or at least, their course-registration choices obey Bose-Einstein statistics…
As background, we had been given some historical data that included a disturbing table showing the distribution of student enrollments over graduate courses. Expressed as a percentage of all graduate courses offered during the time-period in question, the numbers were:
Number of students: | 1-3 | 4-6 | 7-10 | 11-15 | 16-20 | 21-30 | 30+ |
Percent of courses: | 26.8 | 18.9 | 20.7 | 19.8 | 6.8 | 4.5 | 2.5 |
