The first transatlantic telegraph cable to successfully link Ireland and Newfoundland turns 150 this week. Rob Thompson visits John Liffen at the Science Museum in London to see some of the original cable, and Professor Mark Miodownik explains how those pioneering engineers overcame problems and created the moon landing of their time.
