Comedian Ben Miller returns to his roots as a physicist to try to answer a deceptively simple question: what is one degree of temperature? His quest takes him to the frontiers of current science as he meets researchers working on the hottest and coldest temperatures in the universe, and to a lab where he experiences some of the strangest effects of quantum physics - a place where super-cooled liquids simply pass through solid glass. Plus, Ben installs his very own Met office weather station at home. Ben's investigations in this personal and passionate film highlight the importance of measurement and accuracy in the 21st century.

If you're a paleontology buff, this series is for you. And the fun-loving Nigel Marvin provides a great narrative. Explore the prehistoric world in search of sea-based monsters. It focuses on life in ancient oceans during each prehistoric period. Nothing, not the carnivorous dinosaurs of the past, nor the imagined sea serpents and monsters of maritime history, nor the great white shark, salt water crocodile, killer whale and leopard seal of today can compare to the horrifying hunters of the prehistoric oceans.

Embark on an astounding journey across 100,000 light-years to witness key moments in the history of the Milky Way. Using cutting-edge science, National Geographic constructs a 3-D state-of-the-art CGI model of our galaxy. We'll peer into the heart of the Milky Way on the hunt for super-massive black holes, watch how stars are born and die, fly out and above the plane of our galaxy to understand its true shape and scour its dusty spiral arms for the possibility of life

Be prepared to fight your way past all kinds of computer animation. Somehow Patrick Moore's The Sky at Night manages to convey just as much excitement with little more than a couple of diagrams and the presenter's hyperactive enthusiasm. The series cover the history of the solar system and humanity's age-old desire to learn its secrets. Far beyond the inner planets of rock and iron lie the gas giants. Discover the most distant and alien worlds in our Solar System and the moment of genius that allowed scientists to explore them.

This series, presented by Robert Winston, takes us on a journey from birth to death using time-lapse photography, computer graphics and various state-of-the-art imaging techniques to explore every aspect, every nook and crevice of the human body in its various stages of growth, maturity and eventual decay. Though heart-warming in that it shows the commonality of human experience, The Human Body is also a potentially depressing reminder of our frail physicality and mortality." In this episode, follow Jeff and Phillippa from conception to the birth of their first child Bob in An Everyday Miracle. Learn why conception is the most dangerous part of your life, and the struggles that you must go through to even reach the first step. The couple openly discuss their concerns and joy throughout their entire pregnancy and this episode in particular would be well worth viewing by those who are expecting their first child. From experience, this tasteful and informative section captures aspects of pregnancy that the hospital-run Maternity Classes don't explain as well. You even get to see the birth of their child which makes for a great lead into the next section. And in case you were wondering, every day there are around 100 million acts of sexual intercourse taking place in the world resulting in around 910,000 conceptions.

Professor Brian Cox examines how it was that in a universe made of stars, rocks and endless space, a conscious civilisation was born. His latest adventure takes him from a submerged space station in Star City on the outskirts of Moscow, to Ethiopia, high above in the Great Rift Valley, where he encounters the geladas, mankind's distant ancestors. Despite once being Africa's most successful primate, a species who at one time roamed across the entire continent, these days they are found in one just place in the remote Ethiopian Highlands. Cox investigates why these ancestors retreated, yet modern mankind has expanded across the planet.
