We live in a world that is not quite "right." The central tenet of statistical inquiry is that Observation = Truth + Error because even the most careful of scientific investigations have always been bedeviled by uncertainty. Our attempts to measure things are plagued with small errors. Our attempts to understand our world are blocked by blunders. And, unfortunately, in some cases, people have been known to lie.

We measure rainfall and radiation, the depths of space and the emptiness of atoms, calories and steps, happiness and fear. If we could not measure then we could not observe the world around us; we could not experiment, learn, and co-operate. But why did this urge to measure flourish? And when did measurement become ubiquitous? It is an incredible story that spans hunter-gatherer societies to ancient Egyptians, the French Revolution to the relentless quantification of the 21st-century self. It is a tale that tracks humanity's search for dependable truths in a chaotic universe.

In questo libro Piergiorgio Odifreddi affronta le due domande con un approccio più fluido e pratico: invece di provare inutilmente a dirci cos'è il numero in astratto, ci mostra utilmente una serie di numeri in concreto.

As cognitive psychologist Brian Butterworth shows us in Can Fish Count?, many “simple” animals - such as bees, which count trees and fence posts, and guppies, which can size up groups - have a sense of numbers. And unlike humans, they don’t need to be taught. In telling animals’ stories, Butterworth shines new light on one of our most ancient questions: Just where, exactly, do numbers come from?
