Technology is opening up new possibilities for physical, sexual and romantic relationships with astonishing speed. But is seeking human connection virtually a positive step forward or are we stunting our intimate lives? In the first episode of this series, meet a cyber BDSM couple who use tracking technology to fulfill their master slave relationship; an eligible bachelor in Japan who has fallen in love with a virtual girlfriend; and a revenge porn victim whose life was upended when her private naked photos were published online.

New York's Central Park Tower is the second tallest building in the US, and as engineers and builders race to complete this 1,550-foot-tall mega build, they use cutting-edge science and engineering to battle high altitudes and brutal weather.
From the world's longest tunnels to the world's most advanced skyscraper, the series Building Giants reveals the extraordinary innovations that help record-breaking superstructures to be built, and uncovers the inner secrets of how they work.

Following engineers and scientists on a groundbreaking mission as they build, test and launch the James Webb Space Telescope, the most powerful observatory ever constructed, and discovers the astonishing cosmological enigmas it will investigate. Using the latest CGI animation technology, the film will follow the journey and share the incredible cosmological images and mysteries that scientists believe the telescope will capture.
This super-telescope is the next generation successor to the Hubble Space Telescope, with a mirror 6 times bigger. It will also be able to peer back in time. For the first time in space exploration, scientists will be able to explore the formation of the first stars and galaxies and search for planets that can support life.

The series concludes by delving into the world of satirical maps. How did maps take on a new form, not as geographical tools, but as devices for humour, satire or storytelling? Graphic Artist Fred Rose perfectly captured the public mood in 1880 with his General Election maps featuring Gladstone and Disraeli, using the maps to comment upon crucial election issues still familiar to us today. Technology was on the satirist's side with the advent of high-speed printing allowing for larger runs at lower cost. In 1877, when Rose produced his 'Serio Comic Map of Europe at War', maps began to take on a new direction and form, reflecting a changing world. Rose's map exploited these possibilities to the full using a combination of creatures and human figures to represent each European nation. The personification of Russia as a grotesque-looking octopus, extending its tentacles around the surrounding nations, perfectly symbolised the threat the country posed to its neighbours.

Mathematician Dr Hannah Fry explores the mystery of maths. It underpins so much of our modern world that it's hard to imagine life without its technological advances, but where exactly does maths come from? Is it invented like a language or is it something discovered and part of the fabric of the universe? It's a question that some of the most eminent mathematical minds have been wrestling with. To investigate this question, Hannah goes head first down the fastest zip wire in the world to learn more about Newton's law of gravity, she paraglides to understand where the theory of maths and its practice application collide, and she travels to infinity and beyond to discover that some infinities are bigger than others.
In this episode, Hannah goes back to the time of the ancient Greeks to find out why they were so fascinated by the connection between beautiful music and maths. The patterns our ancestors found in music are all around us, from the way a sunflower stores its seeds to the number of petals in a flower. Even the shapes of some of the smallest structures in nature, such as viruses, seem to follow the rules of maths. All strong evidence for maths being discovered. But there are those who claim maths is all in our heads and something we invented. To find out if this is true, Hannah has her brain scanned. It turns out there is a place in all our brains where we do maths, but that doesn't prove its invented.
Experiments with infants, who have never had a maths lesson in their lives, suggests we all come hardwired to do maths. Far from being a creation of the human mind, this is evidence for maths being something we discover. Then along comes the invention of zero to help make counting more convenient and the creation of imaginary numbers, and the balance is tilted in the direction of maths being something we invented. The question of whether maths is invented or discovered just got a whole lot more difficult to answer

Professor Marcus du Sautoy explores why we are driven to measure and quantify the world around us and why we have reduced the universe to just a handful of fundamental units of measurement. He tells the story of the metre and the second - how an astonishing journey across revolutionary France gave birth to the metre, and how scientists today are continuing to redefine the measurement of time and length, with extraordinary results.
