The Measure of All Things

In June 1792, amidst the chaos of the French Revolution, two intrepid astronomers set out in opposite directions on an extraordinary journey. Starting in Paris, Jean-Baptiste-Joseph Delambre would make his way north to Dunkirk, while Pierre-Francois-Andre Mechain voyaged south to Barcelona. Their mission was to measure the world, and their findings would help define the meter as one ten-millionth of the distance between the pole and the equator--a standard that would be used "for all people, for all time." 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 Mechain 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.

THE MEASURE OF ALL THINGS tells the story of how science, revolutionary politics, and the dream of a new economy converged to produce both the metric system and the first struggle over globalization. Amidst the scientific fervor of the Revolution two French scientists, Delambre and Mechain, were sent out on an expedition to measure the shape of the world and thereby establish the metre (which was to be one ten-millionth the distance from pole to equator). Their hope was that people would use the globe as the basis of measure rather than an arbitrary system meted out by the monarchs. As one scientist went north along the French meridian and the other south, their experiences diverged just as radically. After seven years, they received a hero's welcome upon their return to Paris. Mechain, however, was obsessed over a minute error in his calculations that he'd discovered and concealed, and which eventually drove him to his grave. His death forced his colleague Delambre to choose between loyalty to his friend and his science.
