Sir Roger Penrose is more than just a fan of MC Escher's mind-bending art. During the course of a long creative collaboration, the British mathematician and the Dutch artist exchanged ideas and inspirations. Some of Escher's most iconic images have their origin in Penrose's mathematical sketches - while the artist's work has served as a starting point for the professor's own explorations of new scientific ideas". To coincide with the first ever Escher retrospective in the UK, Penrose takes us on a personal journey through Escher's greatest masterpieces - marvelling at his intuitive brilliance and the penetrating light it still sheds on complex mathematical concepts.

On November 25th, 1915, Einstein published his greatest work: General Relativity. The theory transformed our understanding of nature’s laws and the entire history of the cosmos, reaching back to the origin of time itself. Now, in celebration of the 100th anniversary of Einstein’s achievement, discover the inside story of Einstein’s masterpiece". The story begins with the intuitive thought experiments that set Einstein off on his quest and traces the revolution in cosmology that is still playing out in today’s labs and observatories. Discover the simple but powerful ideas at the heart of relativity, illuminating the theory—and Einstein’s brilliance—as never before. From the first spark of an idea to the discovery of the expanding universe, the Big Bang, black holes, and dark energy, NOVA uncovers the inspired insights and brilliant breakthroughs of “the perfect theory.”

In recent years, close study of the aging process has opened up new ways that could help us all live healthier for longer. Can we move beyond treating individual diseases, and instead treat the aging process itself? But would a longer life necessarily be a better life? A loose-knit group of researchers believe the real breakthrough is extending our health span - the period of life spent free of disease". Hear from Laura Deming, who dropped out of M.I.T. at the age of 14 and committed herself to finding and funding projects that can expand the human health span, and Dr. Brian Kennedy, whose work in the basic biology of aging has been crucial to the development of countless other researchers' work.

Earth is the most colourful place we know of. But the colours we see are far more complex and fascinating than they appear. In this series, Dr Helen Czerski uncovers what colour is, how it works, and how it has written the story of our planet - from the colours that transformed a dull ball of rock into a vivid jewel to the colours that life has used to survive and thrive". But the story doesn't end there - there are also the colours that we can't see, the ones that lie beyond the rainbow. Each one has a fascinating story to tell. Early Earth was a canvas for the vast new palette of the colours of life, with the diversity of human skin tones telling the story of how humanity spread and ultimately conquered the planet. Dr Helen Czerski explores the true masters of colour - which are often the smallest and most elusive - travelling to the mountains of Tennessee to witness the colourful mating display of fireflies, and revealing the marine creatures that can change the colour of their skin in order to hide from the world.

Directed by Alex Gibney, it follows the life and work of ex-Apple CEO Steve Jobs. Gibney starts the doc by showing how much people around the world worship Steve Jobs as if he were an idol. He then provides you with a wealth of background information about Jobs' childhood, teenage and college years including how he formed Apple Inc. Fortunately, not all of the doc is hagiography because Gibney does briefly delve into the darker side of Jobs, particularly how selfish he was and mistreated those around him including his ex-wife. Jobs comes across as a charming, intelligent narcissist who knows how to captivate an audience whenever he speaks. In other words, like all great narcissists, he's a very good actor. Gibney certainly knows how to choose the right subject because Jobs' complexity makes him all the more captivating and worthy of a feature-length film. As is usually the case with Gibney's docs, this one is slickly-edited and has just the right amount of comic relief, mostly in the brief video of an young boy joyfully lists all of Apple's technological devices that Steve Jobs created. You'll catch a glimpse of what makes Jobs fallible, and find a little mildly provocative food for thought about the advancement of modern technology, i.e. how technology helps to connect us to one another yet alienates us at the same time.

A compelling (and sometimes humorous) look at the rise and proliferation of this social phenomenon from several varying perspectives and how the lives of those engaged in it are affected. Throughout the course of the film, we examine nearly every aspect of what has become a national and international pastime. A vast range of opinions give their input about this delicate subject and, as such, discussions with notable figures in the entertainment, political and medical fields (among others) are included. The film touches on the many high profile scandals surrounding public officials and the resulting consequences of their actions. In stark contrast, an honest look at the possibility of sexting as a positive development within the framework of healthy relationships is also presented. Sexting exists and is not likely to disappear anytime soon. "ADDICTED TO SEXTING" shows the why, how and what possible purpose it serves.
