Discover how small things will significantly shape the future. From sub-atomic particles to small data and small politics, the small will affect the future in a big way. Presenters Leo Johnson and Timandra Harkness explore the world of the tiniest things, and learn about the power they hold to transform manufacturing, computers and the chances of artificial intelligence emerging in the next few decades. The programme explores how human society might be changed by the growing influence of small politics and the application of small data, and unlocks the secrets of the quantum universe.
