Think of a Number

BBC One
on BBC One London

with Johnny Ball
A lighthearted exploration of science and number.
This week Johnny asks:
What does exactly mean exactly?
Also he finds out how to measure a metre, what keeps a marching soldier in line when he puts his best foot forward and how a laser gets the measure when spying on a locked room.
Meanwhile - how many times can you take accurately three from 333?
