Without us noticing, modern life has been taken over. Algorithms run everything from search engines on the internet to satnavs and credit card data security - they even help us travel the world, find love and save lives. Professor Marcus du Sautoy demystifies the hidden world of algorithms. By showing us some of the algorithms most essential to our lives, he reveals where these 2,000-year-old problem solvers came from, how they work, what they have achieved and how they are now so advanced they can even programme themselves.

Dinosaurs ruled the earth for 150 million years, then suddenly they were gone. Their disappearance is one of the planet’s greatest mysteries – unimaginable, until now. The film proposes a minute-by-minute chronology of the Chicxulub impact and its effect on the dinosaurs and other animals around the world. A blow-by-blow account of the cataclysm that ended the reign of the dinosaurs, and forever changed the course of life on Earth.

We're unlocking the secrets of our planet's voyage and discovering that earth's journey affects us all. The Earth is extremely dynamic. It is spinning on its axis, it's whirling about the sun and it's corkscrewing throughout the this galaxy. And there is the fact than Andromeda and the Milky Way are currently 2.5 million light-years apart, but they're hurtling towards each other at over 250,000 miles an hour. A collision is inevitable. As stars, dust, and gas swirl around each other, gravitational interactions could slingshot our solar system out into intergalactic space.

The center of our galaxy is one of the most nightmarish places in the cosmos. It's the home to some of the most incredible forces the universe has to offer. Gas streaming everywhere, stars are being born and dying and exploding, radiation blasting out. And at the very heart is the super massive black hole, 4 million times the mass of the sun. But also the Milky Way, is our safe harbour, our island in this vast, cosmic ocean. And so to understand the heart of our galaxy, is to understand our home in this cosmic void.

Nintendo goes 3D with Star Fox. Wolfenstein 3D popularizes the first-person shooter format, while Doom ups the ante with networked gaming. 'High Score' is a crash course on the golden age of gaming filled with insightful interviews, brilliant writing, and most importantly, an inspiring and inclusive message.

Does the universe, have a limit? Does the universe have an edge? Looking out to the edge of the universe is tremendously important to understand our place in the cosmos and to understand the universe itself.
Inflation was a formative moment for our universe. By the time it stopped, the universe's basic characteristics were set. There could be regions of the greater universe where inflation didn't stop then. Occasionally a little region will stop inflating and just expand at the normal rate. We could imagine a super large-scale structure where there's different regions of the universe, domains, and each domain has different local constants and laws of physics.
