I’m launching this blog because there doesn’t seem to be any really major history of science blogs out there, because I think it would be nice a place where historians of science can discuss issues in public without having to go through the lengthy journal article process, and because I’m going to be lecturing an introduction to the history of science this spring at the University of Maryland, and I’d like a space where I can talk a little bit about the background of each lecture–texts I relied on to write it, prominent issues and so forth. I’ll also be talking a little bit about my current projects; mostly I want to discuss underlying issues. Hopefully, after a little while, some friends in the profession will be interested in joining, and this project can grow. But for the time being I’ll just consider it a thinking tool.
