Gordon Welchman was one of the original elite codebreakers crucial to the allies defeating the Nazis in World War II. He is the forgotten genius of Bletchley Park. Filmed extensively at Bletchley Park, the centre for codebreaking operations during World War II, this documentary features the abandoned buildings where thousands of people worked tirelessly trying to crack the codes, Hut 6, where Welchman pioneered his groundbreaking work, and the machines that Welchman helped design.

As our expertise in space technology increases, there have been spin-offs in many areas: particularly in communications. This episode examines the profit-making satellite telecommunications industry and emerging techniques designed to increase the rates of data transmission from distant space probes
From the Stone Age to the Silicon Age, materials have helped drive forward our civilisation. By manipulating materials we have been able to transform our world and our lives - and never more so than in the past century when we have discovered and designed more materials than at any other time in human history. (Part 1: Metal) Professor Mark Miodownik travels to Israel to trace the history of our love affair with gleaming, lustrous metal. He learns how we first extracted glinting copper from dull rock and used it to shape our world and reveals how our eternal quest for lighter, stronger metals led us to forge hard, sharp steel from malleable iron and to create complex alloys in order to conquer the skies. He investigates metals at the atomic level to reveal mysterious properties such as why they get stronger when they are hit, and he discovers how metal crystals can be grown to survive inside one of our most extreme environments - the jet engine.
Electricity powers the life support systems that keep our cities running. Lights, transport, communications, and even hospitals rely on this invisible force. Without it, our cities come to a standstill and lives are put at risk. Meet the people who spend tireless hours to make sure that city power grids remain safe, efficient, and uninterrupted
