Of all dreary ideas for a book, the history of the meter might seem to be a sure no-go for any publisher. Instead, this book gives an in-depth portrait of the men measuring France and parts of Spain, in order to find a value for the meter that would stand the test of time. (It didn't, of course, but that's another story.)
Among other things we get to understand the arguments for a common measure of all things, why the meter was so important - and why it was rejected, again and again, even in France.
We also slowly get to understand the nature of error in scientific work, for a non-scientist like me this was very interesting.
Some parts of the book could, in my opinion, have been shortened down a little bit, hence the missing 5th star.
All in all, enjoyable and recommendable!
