For the most part, the world as we know it is shaped by our five senses. But the biological processes that allow our senses to function properly are incredibly complex, even miraculous. In Understanding: The Senses, we meet a variety of individuals who specialise in the study of particular senses. We also address frequently asked questions and highlight the beauty of each sense.
An asteroid hits the earth in the Mexican province of Yucatan in 2007. The impact causes the entire planet to burst into flames. Humankind is catapulted into a very dark age and this re-enacted doco-drama describes what happens 5, 10, 30, 60 and 80 days and lastly 4 months after the impact.
Presented by Steve Leonard we look at how life conquered a hostile dry world and how a string of chance events and global catastrophes led from a fish to a human.
Rare chicken breeder Mark Tully goes on a 10,000km journey across Australia to track down endangered poultry. He has more than 200 breeds among his 2000 chickens, which he claims have saved his life. Tully has battled with depression and has been so low that he became a recluse for nearly five years. The only thing that enticed him out of the house was caring for his beloved birds.

After labouring in secret for twenty years, Charles Darwin is almost trumped by the obscure young naturalist, Alfred Russel Wallace, who has been in the southern world of Australasia for almost a decade. Shocked that someone else is drawing the same conclusions, Darwin knows that he must publish his own work post haste.
Darwin gave us the most sensational idea in biology: evolution by natural selection. But even he knew that it came with difficulties. Tracing the history of these ideas, this program uncovers the accuracy of Darwin's theories.
This BBC clip for senior high school students offers a deeper look at natural selection, including the work of Mendel and Darwin.
If one bullet is fired and another is dropped simultaneously from the same height, will they hit the ground at the same time? Is it possible to knock someone out of their socks?
Cyclones are a fact of life throughout tropical Australia. They are multi-hazard, bringing extreme winds, floods, violent seas and storm surges. This program shows how to prepare your family and property, how to access information and warnings as the cyclone is nearing your area and what to do once the cyclone has arrived.
What would happen if a solid mass of rock and ice was heading for Earth at a speed of more then 200, 000 kilometers per hour? Do we have the science and technology to divert or obstruct such a strong force of velocity? Forget Armageddon - this film hears from top international scientists as they predict the impact of a comet exploding into Earth's atmosphere. Although based on fictional accounts, The Super Comet is a story of survival amidst the inconceivable destruction that would follow, should such a super comet come our way.
Presented by Steve Leonard, this series vists the crucial moments in life's journey to dominate the earth.
This four-part science series explores the phenomenon that surrounds and affects nearly every aspect of our lives but one which we take for granted: light.
The fascinating and sometimes heartbreaking story of the world's tallest children tells how and why human growth goes awry and how the human body copes with the strain of disproportionate height.
In the three-part documentary series, Science and Islam, physicist Jim Al-Khalili travels through Syria, Iran, Tunisia and Spain to tell the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries. This leap is tangible, with terms like algebra, algorithm and alkali all being Arabic in origin and at the very heart of modern science - there would be no modern mathematics or physics without algebra, no computers without algorithms and no chemistry without alkalis.
Jim AlKhalili demonstrates the difference between the Roman and HinduArabic numeric systems and the origin of the decimal point.
Jim AlKhalili meets mathematician Ian Stewart, who explains the significance of Muhammad ibn Musa alKhwarizmi's work to develop algebra and the origin of root.
In this six-part documentary series, a group of scientists tackle increasingly more difficult scientific challenges. The team head to Zanzibar to undertake a series of ambitious experiments. Frustration builds as the scientists struggle to complete the marine challenges without the help of modern technology.
A fascinating look at people with incredible physical strength and the feats they are capable of. The world's strongest couple have a baby who could inherit their amazing muscle capacity. The champion arm wrestler from the US defeats his fiercest opponent with incredible mind power and Mr Universe, Mr World and 'Mr everything else' was a puny Welshman who started weightlifting at 12 and now has strength and body definition to die for.
