The Measure of All Things is the astonishing tale of one of history's greatest scientific adventures. Yet behind the public triumph of the metric system lies a secret error, one that is perpetuated in every subsequent definition of the meter. As acclaimed historian and novelist Ken Alder discovered through his research, there were only two people on the planet who knew the full extent of this error: Delambre and Méchain themselves.
By turns a science history, detective tale, and human drama, The Measure of All Things describes a quest that succeeded as it failed--and continues to enlighten and inspire to this day.
