Maths, measurement and the secrets of the universe.
Measurement is something we take for granted. But imagine a world without measurement. No distance, no time, no weight, no mass. It would be impossible to describe what something looks like, where it is or how it relates to anything. Creating a system of measurement has allowed us to understand how the Earth revolves around the Sun, how time advances. So 'How long is a piece of string?' might sound like an easy question. But as host Alan Davies discovers in this mind-bending programme, finding the answer involves a journey through maths, physics and quantum mechanics via the fundamental nature of the universe. |
