My eyes are notoriously bad, so I am not sure whether I have ever seen a meteor. Others have seen them, of course, but it is important to me to observe them first hand. I even go to the trouble to hike at night in the desert mountains so that viewing conditions will be ideal. I scan the sky through my thick glasses, but to no avail. My companions have sighted several, the latest just to the left of that peak. And still I am unsure. Did I really see the meteor, or was it just that my eye twitched? I suspect that this question has no unambiguous answer and that understanding why it lacks such an answer will provide important clues about the role of observation in scientific theorizing.
