I have just led a private tour for ten of the Dibner Library of Science and Technology, one of the most fascinating of the twenty-one Smithsonian Libraries.
Here’s one of my favorite documents – Sir Isaac Newton’s alchemy notes, written in his kitchen garden in Cambridge.
The librarians brought this document out when we were giving an earlier private tour to the ambassador of the Czech Republic and the Havel family.
