In the first episode, Andrew looks at how people live in five of the world's biggest megacities: London, one of the world's oldest megacities; Dhaka, the world's fastest-growing megacity; Tokyo, the largest megacity on Earth; Mexico City, one of the most dangerous cities in the world; and Shanghai, arguably the financial capital of the world. Andrew compares the sleek skyscrapers and rapid modernisation of Shanghai to the colourful street culture and geographic sprawl of Mexico City. He spends a night living in a one-room shack in Dhaka's toughest slum, taking his turn to fetch water, cook and clean; and he rents a friend in the efficient and high-tech, but alienating, city of Tokyo. As he gets under the skin of each unique metropolis, Andrew discovers how the structure of each megacity defines every aspect of its inhabitants' daily lives. And he considers what the megacities of the future can learn from the metropolises of today.
This episode reveals the fascinating chain of events that made quick and safe travel possible even across the greatest distances a possibility. From the Rolls Royce aero-engine factory in Derby, Michael Mosley, 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 steam locomotive, the internal combustion engine and the jet engine. Our experts explain how these inventions came about by sparks of inventive genius and steady incremental improvements hammered out in workshops. They separate myth from reality in the lives of the great inventors and celebrate some of the most remarkable stories in British history.
The sea level in Venice has increased drastically in the last century or so, threatening the very existence of the city. Global warming and the harmful effects of tourism have amplified the phenomenon of acqua alta (sudden rise in sea level), rendering the traditional responses of inhabitants obsolete. It is urgent to act today. Projects conceived in laboratories across the globe are joining forces to save the city. These include RAMSES, a 3D modelization of the lagoon produced using lasers, which analyzes rises in water level; and MOSE, a series of movable dams costing over 4 billion euros, intended to block the sea in case of acqua alta. The film will take us on this extraordinary journey, the technological and scientific struggle for the survival of Venice, a survival that has been in doubt from its very construction.

We cannot see things like the movement of a sponge because its movements are too slow. But with specialized photography we can see imperceptibly slow and fast movements. See the dynamics of a child's first steps, rainfall, nocturnal animals and butterflies in flight-and the incredible archer fish.
