In Los Angeles, a remarkable experiment is underway; the police are trying to predict crime, before it even happens. At the heart of the city of London, one trader believes that he has found the secret of making billions with math. In South Africa, astronomers are attempting to catalogue the entire cosmos. These very different worlds are united by one thing - an extraordinary explosion in data. Meet the people at the forefront of the data revolution, and reveals the possibilities and the promise of the age of big data.

Predictions underlie nearly every aspect of our lives, from sports, politics, and medical decisions to the morning commute. With the explosion of digital technology, the internet, and 'big data,' the science of forecasting is flourishing. But why do some predictions succeed spectacularly while others fail abysmally? And how can we find meaningful patterns amidst chaos and uncertainty? From the glitz of casinos and TV game shows to the life-and-death stakes of storm forecasts and the flaws of opinion polls that can swing an election, 'Prediction by the Numbers' explores stories of statistics in action. Yet advances in machine learning and big data models that increasingly rule our lives are also posing big, disturbing questions. How much should we trust predictions made by algorithms when we don't understand how they arrive at them? And how far ahead can we really forecast?

Since 2010, Artificial Intelligence is revolutionized by deep learning, neural networks that discern complex patterns in huge quantities of data and react in real time. A.I. is a primal force, like fire. The same fire that warms us can incinerate our homes; A.I. could enslave mankind -- or, join us in a grand alliance to reach the stars.

Every 17 minutes in America, someone is killed with a gun. Politicians can't seem to stop the violence. But epidemiologists, psychologists and big data crunchers are discovering that gun crime spreads like a virus -and science may be able to stop its spread.

With the rapid emergence of digital devices, an unstoppable, invisible force is changing human lives: Big Data, a word that was barely used a few years ago but now governs the day for many of us. The real time visualization of data streaming in from satellites, billions of sensors and GPS enabled cameras and smart phones is beginning to enable us to sense, measure and understand aspects of our existence in ways never possible before". This massive gathering and analysing of data in real time is also allowing us to address to some of humanity biggest challenges, including pollution, world hunger and illness, and it is also helping create a new kind of planetary nervous system. But as Edward Snowden and the release of the NSA documents have shown, the accessibility of all this data comes at a steep price. The Human Face of Big Data captures the promise and peril of this extraordinary knowledge revolution.

Humanity’s potential seems limitless. But could we become as powerful as God? Scientific breakthroughs grant our species seemingly divine abilities. Biologists tinkering with DNA are figuring out ways to grow new life forms, while neuroscientists try to create artificial consciousness. Statisticians around the world are using big data to predict the future and computer scientists have discovered a "God algorithm" that could solve any global problem in an instant. But to truly become God, we not only have to be all knowing, but all being. Quantum physicists are figuring out how to teleport matter at the speed of light!
