The most recent edition of the History of Science Society newsletter highlighted the Dibner Library Lecture I delivered in December. If you scroll to the bottom you will find a link to the other Dibner Library Lectures that are available on the website of the Smithsonian Institution, those by Joyce Chaplin, Albert Van Helden, Ken Alder, Anthony Grafton, Owen Gingerich, and others.
You can read the article here.
The written version of my lecture will be available online as well. I am currently working with the head of special collections at the Smithsonian, Lilla Verkedy, to find images from their books and other materials that we can use to illustrate the lecture. It should be lovely when it is finished!
