This new feature-length biographical film tells the extraordinary and dramatic story of the planet's most famous living scientist, told for the first time in his own words and by those closest to him. Made with unique access to his private life, this is an intimate and moving journey into Stephen Hawking's past and present. Interviewees include Stephen Hawking's sister Mary, his ex-wife Jane, carers and students, as well as colleagues such as Roger Penrose, plus Apollo astronaut Buzz Aldrin, actors Benedict Cumberbatch and Jim Carrey, and Sir Richard Branson This inspirational portrait of an iconic figure relates Hawking's incredible personal journey from boyhood underachiever to scientific genius and multi-million-selling author. And it charts how he overcame being diagnosed with motor neurone disease - and being given just two years to live - to make amazing scientific discoveries and become a symbol of triumph over adversity. Born exactly 300 years after the death of Galileo, Hawking grew up in a family some regarded as eccentric. Always asking questions, he was nicknamed 'Einstein' at school. Hawking blossomed at Oxford, although he only spent an hour a day studying. He noticed that he was becoming clumsy and fell over for no apparent reason. He was diagnosed with motor neurone disease, but nevertheless started a family and embarked on his academic career, finding himself at the heart of a searing scientific debate about the origins of the universe. And as he lost the use of his body, Hawking had to find new ways to think. He went on to write the huge bestseller A Brief History of Time, and the film reveals the high and lows of his resulting fame and fortune.

Albert Einstein, the most famous scientist of all time, was a world-renowned celebrity, greeted like a rock star when he appeared in public. An anti-war firebrand, Einstein also spoke out on issues ranging from women's rights and racism to immigration and nuclear arms control. But today, his image has been neutered into that of a charmingly absent-minded genius. He was, in fact, a powerful force for social change and a model for political activism.
Using a wealth of rarely-seen archival footage, correspondence, and new and illuminating interviews, filmmaker Julia Newman makes the case that Albert Einstein's example of social and political activism is as important today as are his brilliant, groundbreaking theories.

Go with us behind the scenes at CERN to follow one of the most epic and expensive scientific quests of all time: the search for the Higgs particle, believed to give mass to everything in our universe. However, the hunt for Higgs is part of a much grander search for how the universe works. It promises to help answer questions like why we exist and is a vital part of a Grand Unified Theory of nature". At the heart of the pursuit of the elusive particle is the same feature that makes snowflakes beautiful and human faces attractive: the simple and enchanting idea of symmetry.

The biggest rabbit-hole in history: the search of the smallest thing in the Universe. It is a journey where things don't just become smaller but also a whole lot weirder. Scientists hope to catch a glimpse of miniature black holes, multiple dimensions and even parallel Universes. As they start to explore this wonderland, where nothing is quite what it seems, they may have to rewrite the fundamental laws of time and space.

Time i s a concept which is so familiar, and yet recent discoveries have revealed it to be far stranger than we could have possibly imagined. In the final programme in the series, Brian explores the enigma of time - a phenomenon we take for granted but which is one of the biggest mysteries in the universe. He recalls highlights from his TV series that touch upon this conundrum.

One of the Universe's most enduring mysteries is Time Travel. In this episode, we explore the possibilities. Discover why Time Travel into the future is unavoidable in the Einsteinian world of Relativity. As for the past... the laws of physics do not tell us it's impossible, but the bizarre consequences of going into the past and altering the future make for mind-bending science. Finally, we go for the future by traveling to the nearest star, 4.3 light years away... in only 45 days. Our destination may be an Earth-like planet; a planet scientists are now hunting for, and may find in the next 3 to 4 years.
