In trying to comprehend our universe, just how big is big? How far is far? This users guide to the cosmos will bring the incomprehensible down to a human scale such as Venus melting a tank, the density of a black hole compared to 1000 cars in a Coke can, and the comets in the Solar System equated to grains of sugar weighing half a ton.

我们的星球拥有惊人的力量,但却很少在教科书中被提起。这个系列节目第一次通过电视展现地球的神奇力量对人类发展的影响。节目将历史故事的讲述和炫目的摄影镜头紧密结合,给我们呈现一幅原汁原味的人类历史图景。
Iain Stewart tells the epic story of how the planet has shaped our history. With
spectacular images, surprising stories and a compelling narrative, the series discovers the central role played in human history by four different planetary forces.
Episode 1: Water
Professor Iain Stewart continues his epic exploration of how the planet has shaped human history. This time he explores our complex relationship with water. Visiting spectacular locations in Iceland, the Middle East and India, Iain shows how control over water has been central to human existence. He takes a precarious flight in a motorised paraglider to experience the cycle of freshwater that we depend on, discovers how villagers in the foothills of the Himalayas have built a living bridge to cope with the monsoon, and visits Egypt to reveal the secret of the pharaohs' success. Throughout history, success has depended on our ability to adapt to and control constantly shifting sources of water.
Episode 2: Deep Earth
Iain Stewart tells the epic story of how the planet has shaped our history. With spectacular images, surprising stories and a compelling narrative, the series discovers the central role played in human history by four different planetary forces. In this first episode, Iain explores the relationship between the deep Earth and the development of human civilisation. He visits an extraordinary crystal cave in Mexico, drops down a hole in the Iranian desert and crawls through seven-thousand-year-old tunnels in Israel. His exploration reveals that throughout history, our ancestors were strangely drawn to fault lines, areas which connect the surface with the deep interior of the planet. These fault lines gave access to important resources, but also brought with them great danger.
Episode 3: Wind
Professor Iain Stewart continues his epic exploration of how the planet has shaped human history. Iain sets sail on one of the fastest racing boats ever built to explore the story of our turbulent relationship with the wind. Travelling to iconic locations including the Sahara desert, the coast of West Africa and the South Pacific, Iain discovers how people have exploited the power of the wind for thousands of years. The wind is a force which at first sight appears chaotic. But the patterns that lie within the atmosphere have shaped the destiny of continents, and lie at the heart of some of the greatest turning points in human history.
Episode 4: Fire
Professor Iain Stewart continues his epic exploration of how the planet has shaped human history. Iain explores man's relationship with fire. He begins by embarking on an extraordinary encounter with this terrifying force of nature - a walk right through the heart of a raging fire. Fire has long been our main source of energy and Iain shows how this meant that the planet played a crucial role in Britain's industrial revolution, whilst holding China's development back. Along the way he dives in a mysterious lake in Oregon, climbs a glacier of salt, crawls through an extraordinary cave in Iran and takes a therapeutic bath in crude oil.
Episode 5: Human Planet
Series in which Professor Iain Stewart looks at how four geological forces have shaped human history. He explores the most recently established force, humans. It's easy to think of the human impact on the planet as a negative one, but as Iain discovers, this isn't always the case. It is clear that humans have unprecedented control over many of the planet's geological cycles; the question is, how will the human race use this power?
共三集:1.隐匿的王道 2.生命中的化合 3.生命的火花
The Cell In a three-part series, Dr Adam Rutherford tells the extraordinary story of the scientific quest to discover the secrets of the cell and of life itself. Every living thing is made of cells, microscopic building blocks of almost unimaginable power and complexity. “I am normally not a lover of scientific docu’s but this one I found I had to watch all 3 parts back to back”.
The Hidden Kingdom
The first part explores how centuries of scientific and religious dogma were overturned by the earliest discoveries of the existence of cells, and how scientists came to realize that there was, literally, more to life than meets the eye.
The Chemistry of Life
This episode explores how scientists delved ever deeper into the world of the cell, seeking to reveal the magic ingredient that can spark a bundle of chemicals into life. Their discoveries have brought us to the brink of being able to create life for ourselves.
The Spark of Life
The final part reveals how our knowledge of cells has brought us to the brink of one of the most important moments in history. Scientists are close to repeating what has happened only once in four billion years - the creation of a new life form.

More than half of us now live in cities. Crowded, chaotic and bursting with life - these are places under pressure. In this brand new series, Dan Snow, Anita Rani and Ade Adepitan go behind the scenes to reveal the hidden systems and armies of people running some of the greatest cities on earth. Find out how Mexico City keeps its inhabitants safe from earthquakes, and meet local people who offer an inside look at life in metropolises like Delhi and Hong Kong. Meanwhile, Moscow's incredible architecture shows that the world's busiest cities also have some of the richest histories.
