The Basis of Measurement Vol 1
The central theme of the book is the inconsistency in units of measurement, and how the authorities have tried to deal with it. Should there be a central standard, or is it better to have some 'natural definition'? Certainly action was necessary since, for instance it is claimed that there have been 68 different units of length called the ell, and that's just in one country alone (Switzerland). No wonder they were keen to adopt the metric system, and so leave this muddle behind. So maybe anyone who longs to go back to 'traditional' units of measurement should spend some time reading this book!
