Technological advances are crucial for both our social and economic well-being. From NASA's deep space missions to the latest mobile phones and fibre optic networks, we live in increasingly hi-tech times which require three key elements to succeed - ambition, investment and a third element which is easily overlooked, and costs nothing, but without which our high-tech visions might just go up in smoke….

We'll discover how those disasters could have been easily avoided, and how valuing our number sense might help us steer clear of making similarly expensive mistakes in our own lives.
