Two questions in my referrer logs this morning: first, that age-old Monty Python-inspired one, “tell me again how sheep’s bladders may be used to prevent earthquakes”. I think, if we can calculate the air-speed velocity of an unladen swallow, someone ought to finally be able to answer this one. Does anyone have a sheep’s bladder handy?

And the second question, which I don’t believe is Python-inspired, is “what has been the most surprising challenging interesting disappointing tedious confusing or memorable dimension of your study in this course”? Please be as concise as possible. This will count for half your grade.
