Send in your favorite journal articles….

Some articles are great, no matter your specialization. Some are downright essential. Here’s a chance for you to share the articles you think every historian of science should read. Comment to the post and give the citation and your reason for choosing it, whether personal, professional, or inexplicable. Online articles are preferred (please provide link) but for the really great ones, most of us are willing to seek out paper copies. Send ’em in!
