As part of my introductory physics class next year I'm planning on including more history of science into the curriculum. During one class I've decided to include excerpts of translations from Galileo's Starry Messenger and Dialogues Concerning the Two Chief World System (I'll also include parts of Two New Sciences, but this will be in a different class). Part of the discussion in this class will include a copy of Galileo's Papal condemnation and subsequent censorship. To bring the discussion back to contemporary issues I'd like to allow some time for a discussion about the role censorship plays in modern research. Being an educator and not a researcher, I don't have any first hand experience with censorship. I have found some decent resources online (this article by Brian Martin, for example), but I am interested in hearing some opinions from individuals with research positions (academic or otherwise) about the role of censorship in current research.
