As one of my aims for the State of the Unit is to help the general public understand what the redefinition of the kilogram will mean (and how it came about), I am naturally interested in examples of public instruction on measurement. There is quite a precedent in the history of the kilogram. Michael Trott, the film's science advisor, has bought some books—very, very old books, i.e., 1790s—that teach the newly invented and launched metric system to the general public of France.
On the film's blog, I have put together some thoughts about the public instruction one can glean from these books and from the demands for standardized weights and measures published the summer before the French Revolution: "Metrication in 1790s France: When people got what they asked for, but not what they wanted"
Things are going well for me and this project, and I hope you enjoy the blog post. Scroll down for many pictures of the books! :D
