The AP recently made headlines by saying that it was OK to begin a sentence with “Hopefully”. My mother is rolling in her grave as we speak. I don’t care what AP says, I still think it’s ungrammatical.
However I see it all the time in my work. Scientists love to begin sentences with adverbs: “Interestingly, mouse A ate cheerios, while mouse B preferred cornflakes.”
There is so little room in scientific writing for self-expression that I think they slip the words in the only place they can see it. And it saves them a transition.
One can see how it’s a larger issue. The people who named a 17-mile underground tunnel that they are going to use to recreate the big bang just The Large Hadron Collider perhaps need some creative assistance. Although “the God particle” is a pretty fucking awesome name (and concept).
Are you a prescriptivist or descriptivist? Which side are you on?
