As a way to provide a different perspective on some the discussions we have entertained these last few weeks on the blog, it would probably be worthwhile to have a look at the last issue of Isis, where the focus is on: “What is the Value of History of Science?”
Some of the articles, such as “Does Science Education Need the History of Science?” or “How Can History of Science Matter to Scientists?” seems (I did not read them yet) particularly relevant to our concerns.
