A few months ago, I had a hypothesis that the time to take a trip on Budapest transit was quantized—always an integer multiple of (half an hour, minus a minute for each week I’ve been here). This would’ve had several interesting consequences, including that today, when I’ve been here for exactly 30 weeks, something interesting should’ve happened, like the transit system breaking down. But I rode the tram and the bus; everything seemed normal; trips took reasonable amounts of time. So, I’m forced to throw out that hypothesis.

Next hypothesis: Budapest is really a covering space of a punctured disc, and I should look for subtle differences when my winding number around some point in the Danube changes.
