38 people coughed up $10 or more to see “Counting from Infinity,” the movie about UNH lecturer Tom Zhang’s twin-prime breakthrough, followed by a talk with me and Zhang’s colleague Edward Hinson, a UNH math professor, in Concord this week.

If you missed it, shame on you. I asked the crowd and about 80 percent of them had taken at least one calculus class. Man, that’s my kind of audience.

You can watch most of the talk, videotaped with a hand-held smartphone, at Red River’s Facebook page right here.
