Children's perception of numbers is not a simplified version of adults', but rather a completely different version. They seem to care about the logarithm of the number, where the distance between numbers is perceived logarithmically. For example, the distance between one and two is perceived as huge, while the distance between eight and nine is tiny, reflecting the doubling nature of the logarithmic scale.
First aired back in 2009, this episode is all about one thing, or rather a collection of things. Whether you love 'em or hate 'em, chances are you rely on numbers every day of your life. Where do they come from, and what do they really do for us? This hour: stories of how numbers confuse us, connect us, and even reveal secrets about us.
