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.
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 3: Ceramic) Professor Mark Miodownik traces the story of ceramics. He looks at how we started with simple clay, sand and rock and changed them into pottery, glass and concrete - materials that would allow us to build cities, transform the way we view our world and communicate at the speed of light. Deep within their inner structure Mark discovers some of ceramics' most intriguing secrets. He reveals why glass can be utterly transparent, why concrete continues to harden for hundreds of years and how cooling ceramics could transform the way we power cities of the future.
One of the ancient world's most iconic buildings, the Colosseum is a monument to Roman imperial power and cruelty. Its graceful lines and harmonious proportions concealed a highly efficient design and advanced construction methods that made hundreds of arches out of 100,000 tons of stone. In its elliptical arena, tens of thousands of gladiators, slaves, prisoners, and wild animals met their deaths. Ancient texts report lions and elephants emerging from beneath the floor, as if by magic, to ravage gladiators and people condemned to death. Then, just as quickly, the Colosseum could be flooded with so much water that ships could engage in sea battles to the delight of the crowd.
Whether serving as Christian church, Islamic mosque, or secular museum, Hagia Sophia and its soaring dome have inspired reverence and awe. For 800 years, it was the largest enclosed building in the world—the Statue of Liberty can fit beneath its dome with room to spare. How has it survived its location on one of the world's most active seismic faults, which has inflicted a dozen devastating earthquakes since it was built in 537? As Istanbul braces for the next big quake, a team of architects and engineers is urgently investigating Hagia Sophia's seismic secrets. Follow engineers as they build a massive 8-ton model of the building's core structure, place it on a motorized shake table, and hit it with a series of simulated quakes, pushing it collapse—a fate that the team is determined to avoid with the real building.
Nothing has shrunk the globe more than our extraordinary ability to talk to one another across the oceans and continents. Episode three of The Genius of Invention reveals the fascinating chain of events that made such every-day miracles possible. It tells the story of the handful of extraordinary inventors and inventions who helped build the modern world by harnessing electricity and electromagnetism to enable us to send instant messages across vast distances. Michael Mosley and academics, Prof Mark Miodownik and Dr Cassie Newland tell the amazing story of three more of the greatest and most transformative inventions of all time; the electric telegraph, the telephone and wireless communication. Our experts explain how these inventions came about by sparks of inventive genius and steady incremental improvements. They separate myth from reality in the lives of the great inventors and celebrate some of the most remarkable stories in British history.
It began as an audacious idea: to establish a permanent human presence in the most hostile environment known to man -- space. It's a dream that would bring together two former Cold War enemies and lead to the most expensive structure ever built. Discover the inside story of the International Space Station. See how NASA engineers triumphed over decades of seemingly insurmountable obstacles to develop Skylab, Space Station Freedom, and finally the International Space Station.
Mankind has always looked at nature to solve problems, taking a cue from the solutions that biological systems have refined through natural selection. In this episode we look at a robotic plant that mimics the mechanics of plant roots, and dive underwater to see robots inspired by fish.
