The Invisible Universe

   2018    Science
It is one of the most unnerving discoveries in space science - that most of the universe is missing. We live in a material world, so instinctively we know what normal matter is - the world around us, the planets, stars and interstellar dust. But scientists currently estimate that 95 per cent of everything in the universe is actually - one way or another - invisible.
Some of this is ordinary matter that we just can't easily see. But there's also stuff that's much more weird. For instance, there's a new kind of matter we think is out there, but whose very existence is still largely hypothetical - dark matter. And most mysteriously of all, scientists think there is an unknown form of energy pervading the universe that we know so little about, all it has so far is a name - dark energy. Embark on a tour of this invisible universe, and shows how its existence - or lack of it - will define the fate of the entire universe.

Can We Build a Brain

   2018    Technology    HD
Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches... the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence?
The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. The documentary looks at how far we’ve come and where machines are headed as their software becomes ever more... cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?

Catching the Sun

   2016    Technology
The film captures the global challenge to lead the clean energy future by profiling U.S. and Chinese workers and business leaders who are racing to make crucial breakthroughs in the field. Catching the Sun debunks a false dilemma that clean energy requires sacrificing economic prosperity.
Through the stories of an unemployed American worker, a Tea Party activist, and a Chinese solar entrepreneur, we will explore the global energy transition from the perspective of workers and entrepreneurs building solutions to income inequality and climate change with their own hands. Their successes and failures speak to one of the biggest questions of our time: will the countries actually be able to build a clean energy economy?
