When I traveled to Europe earlier this summer with my brother to watch some World Cup soccer games, we engaged in a couple of knowledge-based contests to pass the time on our long flight to Munich. For instance, we each attempted to independently write down every country in the world, with each continent (more or less) a separate contest. We are both pretty strong on geography, and it turned out we had little problem dredging up the Lesothos and Andorras of the world, though neither of us demonstrated strength in Oceania. And, embarrassingly, I did not think of Azerbaijan. We moved on to other lists, like major little baseball hitters with more than 500 home runs (sorry Eddie Mathews and Eddie Murray, I forgot you). We tackled the elements of the periodic table cooperatively, something which I do think I have contemplated in over twenty years, since high school chemistry.
