• QUESTION: is the union of people who want to hear a lecture on tribbles and people who want to hear a lecture on density dependence equal to the intersection of people who want to hear a lecture on tribbles and people who want to hear a lecture on density dependence?

  • Good point. Probably they’re as close to equal as makes no difference. Nevertheless, I hereby resolve that, when I come to the point in my career that I have to explain density dependent population growth to undergrads, there will be tribbles.
