Our internet service (cable) was down all day today. It was fixed when the cable guy brought a new modem (plus hours of fiddling by us to get it to work right). Megan is convinced that the cable guy was an idiot, and he accidentally hit on the right solution. We started discussing whether he could be said to have “known” and I started wondering if this was a rare real-world example of a Gettier problem. (I’m not really clear on what it means for a belief to be “justified” so I’m not sure.)
In other internet news, my e-mail provider has started dropping mail sent to my Ars Math address. I apologize if you sent me a mail and I did not get it. I’ll be switching providers shortly.
