Time MachineFrom the creation of the highest mountains to the opening of a flower's petals, time controls the world around us. To understand this super-powerful force on Earth, we must wrench control of time ourselves - compressing, expanding, stopping and dissecting it, to reveal how the passing of time shapes our world and lives.

The World Shaped By Time. First in a three-part documentary series offering an insight into the dramatic forces that shape life on Earth, using speeded-up footage that compresses centuries into seconds. The programme follows the movement of mountains, rivers, glaciers and the sea, and offers a glimpse of what the future might hold, revealing how the Great Rift Valley may well be on its way to becoming the next ocean.

Life: The Race Against Time. How the passing of time on Earth affects life on a variety of levels, from the daily opening of a flower's petals to the evolution of the horse. A swift journey through the seasons demonstrates how caribou spend most of their time on the move, while the flying squirrel's body clock, attuned to the rhythms of the Earth, is revealed to be the most accurate in nature.

Masters of Time. The last episode in the series examines how humans perceive and experience time, investigating the internal body clock which tells people when to eat, drink, sleep and relax. The importance of accurately measuring time is explored in relation to human evolution, and there's a debate about whether mankind will ever be able to travel between past, present and future.
