A Good American

   2015    Culture
A Good American tells the story of the best code-breaker the USA ever had and how he and a small team within NSA created a surveillance tool that could pick up any electronic signal on earth, filter it for targets and render results in real-time while keeping the privacy. The tool was perfect - except for one thing: it was way too cheap. Therefore NSA leadership, who had fallen into the hands of industry, dumped it - three weeks prior to 9/11.
This is the story of former Technical director of NSA, Bill Binney, and a program called ThinThread.

Your Brain on Tech

   2018    Technology
Two and a half thousand years ago, the Greek philosopher Socrates worried that the wide use of writing would have a negative impact on people's minds. He said that writing would create forgetfulness, because people will not use their memories. They would trust the external written characters and not remember themselves. In a world with an ever-growing tech industry, Michael Stevens tries to find out what effect technology has on our brains. He finds Technology isn't just changing our lives, it's changing our brains. In his experiments he tests what just 10 days of gaming does to things like our spatial memory.

Isolation

   2017    Medicine
Your brain is like a hungry sponge. It's constantly absorbing information. It thrives when stimulated. Between smartphones and books, and movies, and friends and family, thousands of sensations are constantly going into our heads. But what if it all got cut off?. Imagine being confined to a 10-by-10-foot room in complete isolation. No timekeeping devices, no phones, no books, nothing to write on, no windows. Psychologists say that fewer than three days in a room like this can lead to brain damage. I will be staying in this room for three days.
Michael explores the effects of isolation on the human mind by subjecting himself to a very interesting experiment.

The Story of China Ancestors

   2016    History
Michael Wood embarks on a great historical adventure, exploring the stories, people and landscapes that have helped create China's distinctive character and genius over four thousand years. Is the history of the world's newest superpower, from its ancient past to the present day.
Starting in Wuxi, Michael joins the Qin family reunion, when 300 relatives gather to worship their ancestors on Tomb Sweeping Day. 'Like the nation, the family has been through so much,' one says. 'Now everyone wants to know - what are our roots?'
Looking for the origins of the Chinese state, he visits the excavations at Erlitou and sees an exquisite turquoise dragon sceptre from 2000 BC. China's first writing is found on 'oracle bones' dug up from the Shang royal tombs at Anyang in the 1920s. At the Beijing Planetarium, Michael travels back in time as astronomers plot the planetary conjunction that the ancients believed foretold the overthrow of the Shang Dynasty. Next, the Age of Philosophers and Confucius, whose book Analects has had greater influence worldwide than even the Bible, according to some. In Xi'an, we hear how the First Emperor united China and created the authoritarian Qin state that gave us the word China. Finally, Michael returns to the temple fair in Henan for a dramatic night ceremony to give thanks to the ancestors. China, Michael concludes, is rising again, not just because of its economic strength, but because of the incredible solidarity of the Han Chinese view of their own civilisation, their sense of family and, of course, the presence of the ancestors.

The Universe Season 7 Stonehenge

   2014    Science
Perhaps the most mysterious structure on Earth, Stonehenge has stood on a plain in Southern England for 5000 years. Its foundations predate the Great Pyramids. It is one of mankind's most ancient mysteries. Why is it here? Is it a temple? A burial ground? A place for sacrifice? Or could the mystery of Stonehenge be revealed in its builders' desire to explore the unknown heavens and touch the universe? Using the cutting-edge computer-generated imagery that takes us into deep space, we'll also go inside a virtual Stonehenge to see what the ancients saw and push this prehistoric marvel to give up its age-old secrets.
In this episode we explore the possibility that this was a prehistoric astronomical observatory. Here ancient astronomer priests may have divined the complex movements of the Sun and Moon, recognizing patterns that would not be discovered elsewhere for thousands of years. The primitive Shamans may have also been the first astronomers to predict eclipses.
