BBC World Service - The Thought Show, Memorable Number of the Year

In More or Less, Tim Harford hears Robert Peston’s most important number in the world

In More Or Less, Tim Harford presents more numbers of the year, in Trending Anne Marie Tomchak looks at social media platforms and the Why Factor's Mike Williams is on the moon.

In More Or Less, Tim Harford hears BBC Economics Editor Robert Peston’s most important number in the world and he asks the international editor of The Economist Helen Joyce and Dr Hannah Fry of the University of London to choose their most memorable numbers from 2014.

In Trending, we take a look at where people are having social media discussions, we interview David Karp, the founder and CEO of Tumblr, a micro-blogging site with more than 200 million blogs, and ask if people are moving from public social networks like Twitter to more private platforms such as chat apps? The BBC’s app editor Trushar Barot tells us why different platforms are popular. And, we speak to model and actress Lily Cole who has spent the past year setting up an online community that can share and help people out. Called Impossible, the website is being used in around 70 countries. 

Why has the moon fascinated humans everywhere and for all time? In The Why Factor, Mike Williams explores the moon in culture, how it affects life on Earth and he asks Alan Bean, one of the handful of people who have walked on it, what the moon is really like.
