jfruh writes: A bewildering array of communication mediums have arisen over the 15 years, from SMS to Twitter direct messages, and yet despite repeated claims of its imminent demise, e-mail maintains its quiet, no-fuss dominance over how we touch base with each other. Tech writer Kevin Purdy decided to do a week-long e-mail fast to see what he missed and what he didn't. After seven days, 443 missed messages, a lot of anxious opening of browser tabs only to close them again, he came to some conclusions: that e-mail really is quite important, and that he's subscribed to way too many reminder services.
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
