p 　　A witty, exhilarating and mind-expanding exploration of the word of our times - data - with mathematician Dr Hannah Fry Following in the footsteps of BBC Four 三九 s previous gleefully nerdy, award-winning maths films The Joy of Stats, Tails you Win - The Science of Chance and The Joy of Logic, this new high-tech romp reveals exactly what data is and how it is captured, stored, shared and made sense of Fry also tells the story of the engineers of the data age, people most of us have never heard of despite the fact they brought about a technological and philosophical revolution br 　　For Hannah Fry, the joy of data is all about spotting patterns She 三九 s Lecturer in the Mathematics of Cities at UCL as well as being the presenter of the BBC series Trainspotting Live and City in the Sky, and she sees data as the essential bridge between two universes - the tangible, noisy, messy world that we see and experience, and the clean, ordered, elegant world of maths, where everything can be captured beautifully with equations br 　　Along the way the film reveals the connection between Scrabble scores and online movie streaming, explains why a herd of Wiltshire dairy cows are wearing pedometers, and uncovers the remarkable network map of Wikipedia What 三九 s the mystery link between 三九 marmalade 三九 and 三九 One Direction 三九 br 　　The Joy of Data also hails the giant contribution of Claude Shannon, the American mathematician and electrical engineer who, in an attempt to solve the problem of noisy telephone lines, devised a way to digitise all information It was Shannon, father of the 三九 bit 三九 , who singlehandedly launched the 三九 information age 三九 Meanwhile, the green lawns of Britain 三九 s National Physical Laboratory host a race between its young apprentices in order to demonstrate how and why data moves quickly and successfully around modern data networks It 三九 s all thanks to the brilliant technique first invented there in the 一九六0s by Welshman Donald Davies - packet switching - without which there would be no internet as we know it br 　　But what of the future, big data and artificial intelligence Should we be worried by the pace of change, and what our own data could and should be used for Ultimately, Fry concludes, data has empowered all of us We must have machines at our side if we 三九 re to find patterns in the modern-day data deluge But, Fry believes, regardless of AI and machine learning, it will always take us to find the meaning in them p
