He also convinced his daughter that she'd explode if she left the house.


This week, big data in the sky, on the walls, even on your butt. Hey,


Lewington, get off your butt! There are a few things I love more


than Computex eight made beautiful. -- macro -- compter data. It is even


better when he can throw it up onto a circular walk and then access it


all from your evil genius' chair. First I will destroy the earth! Then


the solar system! And, finally, the entire galaxy! Apart from Elvis.


This is the data observatory, at London's imperial college, from


where you can observe any data you want. That's where we are right now.


Today, this professor is using it to show me financial transactions,


specifically all of those being made right now using the digital currency


bitcoin. These are where the bitcoin transactions are happening around


the world right now and here we can see the individual transactions as


they happen. What's going on? This is somebody who is hoovering up lots


of little amount of bitcoin from their wallet and using it to make


payments. So they are just going down the back of the sofa? That's


right. Maximum vacuuming happening here. A lot of change down the back


of the sofa. And a lot of activity is happening in China, but we can't


see it because it is behind the great firewall of China. Unusual


transactions look even more lovely. In fact, this malicious activity


looks a bit like a parasitic worm, which I guess is what it is. There's


also beauty in how the bitcoin currency works and how transactions


are recorded. Just like a bank will keep a record of the movement of


money, something called a ledger, there is a record of all the bitcoin


transactions that have been made. It's a massive file called the block


chain. And the brilliant thing about it is it can't be tampered with. You


can't fake an entry, delete a payment or create new fake coins.


That's because copies of it are stored on thousands of computers


across the globe. You can't alter the record of events unless you can


somehow tamper with each copy of the file on the majority of these


machines. Let's face it, realistically you can't. I about to


make a bitcoin payment on this phone and you will see that transaction


entered the bitcoin network. Here we go. Sending payment. There it is!


There's my payment. It is now in the network waiting to be verified.


Already, all of these computers around the world know about that


transaction entered a few minutes' time one of their will verify it. --


and in a few minutes'. And there will be a permanent record of my


transaction that in theory cannot ever be tampered with or undone. But


the block chain method is more than just a way of keeping big queen


records. The idea of a tamper-proof ledger stored on many machines is


being taken seriously as a way to keep a record of all sorts of


transactions. We have been to meet a view block chain entrepreneurs. -- a


few. I think the block chain to me is all


about efficiency. What's cool about a block chain is that it is software


that operates autonomously. Much like in a music is this, like the


combination of the iPod and iTunes marketplace. We think it has the


potential to be that disruptive. It is a piece of technology that you


can facilitate and trust amongst individuals, governments,


enterprises and business. We are in the city of London at the theory and


developer conference. 300 or so people have paid ?750 each to be


here for the week to learn more about the block chain. They're


calling it web 3.0 and they say this is the weight the incident was meant


to be, not run by anybody but sort of run by everybody, because no one


person control it. The reason why so many people I hear is because they


think it could dramatically improve how markets work. -- are here. Right


now if you want to sell your house it requires a lot of paperwork and


legal agreements, solicitors, and it can be slow and expensive. The idea


is that this could be done as a digital transaction that recognised


on the block chain by faster and secured without third party is


getting involved. The possible implications of that, what you can


do with that, are almost too many to imagine. If you think about our


existing financial system, they're holding all this money and that is


then a lot of power and that's one of the really compelling things


about decentralisation. It doesn't have some person sitting in the


middle of it who can change the system if they want to. Bureaucracy


in general will start floating away as we get governments,


institutions, individuals, businesses and enterprises to be


able to trust and deal with each other as transparency and diesel --


transparently and easily as we can send an e-mail to each other. A lot


of bureaucrats will be watching this, worried about their jobs!


Who is behind this is a technology? The inventor of it, on application


of the block chain, is this 21-year-old. In general, I think we


are seeing new technological eras that are as different from each


other as say the Bronze Age and the Iron Age, but we see them, but every


ten or 20 years. No single technology will bring about the


exact utopia for your political ideology but it does make


significant steps in that direction. By working together, we can create


systems that are much more reliable than any single one of us can ever


be. This is because the block chain is a distributed system which means


no one person is in charge of checking it. Every user effectively


has a copy of the data at a certain number of those users check the


transactions to make sure they all are accurate and fit together. It is


like a decentralised, distributed system, as a possible way of making


the internet more democratic. That kind of connection, you can change


technology that might change society, the benefits are clear to


the typical user and to the way the internet works. But it is certainly


not without its difficulties. Indeed, this kind of technology is a


double-edged sword. In a way it lacks a central point of control,


but that's also a problem. Imagine if somebody transferred ownership of


your car or your house to someone else in a malicious manner. How


would you get repossession of your house? There is no appeal body could


go to. Also, as the sophistication of this technology improves, people


will create viruses that will attempt to accumulate economic


wealth, in the same way as they currently try to write viruses to


steal your bank details and so on. Now it will steal your assets.


Hello and welcome to this week's at ology round-up. It was the week that


these children's company revealed its tech. Over 6.3 million


children's account up in composite -- the most as well as almost 5


million parent accounts. The US, France and the UK were most


affected, as the names, addresses and pictures of users were stolen.


It was also the week that the internet sensation Psy released


another catchy, but incredibly creepy, music video. And supermodel


Kendall Jenner won Instagram. She posted the most likely to this year,


with 3.2 million likes. And big news for Facebook, as Mark Zuckerberg


announces he will give away 99% of his shares in the company. That's a


cool 45 million dollars. His shares are to fund an initiative run by him


and his wife, which basically aims to save the world. Q diseases and


equality. He also became a dad and shared it fire, you guessed it. And


it was also the week that NASA created a humanoid robot, which cut


serious shapes. Destined for Mars, it is being tested for all sorts of


movements which could contribute to its future intergalactic missions.


Not quite ready for a Strictly just yet.


By now you will know I am a bit of a weirdo when it comes to turning data


into pretty pictures. Yes, yes, it is. This is the new big bang data


show in London. Part celebration of and part warning about the amount of


data flying around the world, freely available to anyone looking. Here,


some of the public accessible selfies taken in London and here are


some of the masks designed to defeat facial recognition software,


although even I can tell this won't work. This is a wall of selective


tweets meet near Somerset House over the last few days. Wide-awake and


awaiting the postman. If ever I survive a nuclear war and there's no


internet or infrastructure, I would flee to Cambridge. I can't read that


one out. Think of it as a cross-section of London's thoughts.


The most relaxing peace to look out has to be this one. This, believe it


or not, is the stock market in Galaxy form. Every star is a


company, every flash is a trade in that company's stocks. When he just


to see a small flashlight that it is probably ?10 million changing hands.


Tell me about these weekly creatures crawling around. -- wriggly. Those


are artificial lifeforms that live in the sky with the stars and they


feed from the light generated by the trading. These creatures evolve over


the course of the exhibition, getting better at finding those


light sources and feeding off the brightest trades. So, it is just


before 2:30pm UK time, just before 9:30am New York time. Is that when


the stock exchange opens? Yes. You will see when the New York Stock


Exchange opens. You can't miss it. Just before it opens, the creatures


look as if they are getting excited. They do. Yes. Oh, wow! Ding aling,


ladies and gentlemen, New York is online. There has been a lot of


work, helping us to get clearance from individual stock exchanges


around the world to use this data. Because it is so valuable. It was


the sort of dotcom era when we started this. I was asked to go in


and fix it. I went into the Gallery and what had happened is because the


stars clustered together based on correlations between companies, the


market had collapsed and all the companies had dropped their prices


at the same time, which meant every star correlated with every other


star, so they all basically collapsed into a black hole. Oh my


goodness. You visualised the dotcom crash as a buy coal? As it happened.


How poetic! -- as a black hole. Next, we have been looking at other


ideas to help us relax. These days, we can suffer from data


overload and with so many of us living such busy lives with so much


going on around us and always being contactable on one of these, it is


not surprising that we can feel a bit stressed out. I'm looking at


technology that can track your tension and even relieve it. When


worn in the white position, this standard activity tracker can also


track your breathing and therefore monitor your stress levels. -- worn


in the right position. It's senses understand body activity and


breathing patterns. And then some clever algorithms identify your


moments of focus, calm and activity as well as any moments of tension.


As well as selecting daily targets, you can set alerts like a warning if


you have been tense for two minutes, and then the app has exercises to


help get you back on form. Exhale slowly and notice how it feels as


the air leaves your body. My only issue is that the device has just a


six hour memory so you have to keep connect it to your phone, unlike my


regular activity tracker, which I just sync when I feel like it. When


we start to feel pressure, our fingers become moist and that can --


affects the ability for the skin to conduct electrical current. The Pip


is monitoring how that works. Each time you do it, you tried to improve


your score. 75% is quite good. It synchronises to various apps. One is


relax and race which is a game where the more relaxed you are the fastest


you move through it, so train yourself to become calmer on demand


and you can keep bettering your score. I'm not sure what your Dragon


is a very relaxing picture. Of course, I stress levels can


seriously impact Dzeko and mental health. -- high stress levels can


seriously impact physical and mental health. There is some irony in


technology coming to the rescue. Meditation apps have been around for


a while now and they teach the basics of meditation and mindfulness


in manageably short sessions. My first thought was that I didn't even


have time for that, which would have shown how much I needed it. Find a


quiet place to sit where you won't be disturbed. Yet all of this


tracking proved how calm I am. Of course this technology cannot take


away the pressures of modern life but it can encourage us to think


about how we feel so we can do something about it. Back at the


exhibition, a timely reminder of how the amount of data we are generating


has exploded and, counterintuitively, how little space


we now require to install it all. -- store. In the future, we may keep it


biologically. We already do. She has been working on this for a couple of


years. And she has taken the DNA from discarded cigarette butts and


chewing gum... Yes. She has been looking for traces of DNA on items


that have been left in public spaces. These things that she knows


are samples of this essential set of data that identifies us, like our


DNA. She has created faces from the DNA found on these things? Yes. Can


this possibly be anything like? They are things you can know like the


colour of the skin, the ethnic opposition of your background. But


you cannot know how pronounced your chin is, for example. Aspects that


are real and aspects that exist in potential space. But the most


interesting thing is that some of our most personal data, we are just


spreading it around. We are literally leaving it on the street.


So if you recognise yourself, you spat out some chewing gum on Wilson


and Stanhope in Brooklyn, New York. Is that if you, put it in the bin


next time. -- if. Headphones socket don't like fluff. This is a tip.


Insert and clean. That is better. This is the London situation room.


There are two works on here. This is London 2036. We will deal with that


in a moment. First, the work on these walls. This is some of the


data that London is generating right now from Twitter, Instagram and


transport for London. It looks very text heavy there but it is being


visualised on this wall here and this is the story of how it was


made. We are a data visualisation studio and we were approached for a


new commission for an exhibition they are doing. We were asked


specifically to investigate real-time data. Our aim is to


democratise data and make it accessible to everyone and we do


this in a visual way. We are looking at three different types of data,


three different sources. TFL, Instagram and Twitter. This is a


sweet. It is not just that which we share. Is quite small after all. It


is just one line. The rest is the metadata associated with the sweet.


Time, when it was created, latitude and longitude. Our main aim when we


create data is to communicate a story. That is generally true of


every data visualisation we create. Somehow they deeper purpose. This


piece looks at telling everyone across the exhibition what data is


and how it can be visualised to create a story. As soon as something


is posted, we analysed and we cross reference with a list of 2500 words


that have a score from -5 two positive five. The pink represents


positive words and cyan negative words. During a normal day, we will


get between 70000 and 80,000 tweets. You are never going to be


able to process as much information as I computer and visualise it, so


it gives you the key trends and patterns and gives you insight,


allowing you to investigate in a much more targeted way than you


would if you just had an Excel spreadsheet in front of you. That is


London today but what is London going to be like in 2036? That is


the question we are about to answer. Your challenge on this game


is to make a series of infrastructure changes based on the


evolving needs of the capital. But will you make the right decisions?


The game asks you to make choices about how London should develop.


What kind of transport will you prioritise, where will resources


like water and power come from for the city's growing population, and


more to the point, where will everyone live? In order to keep


services running, we need to invest in more self driving cars or more


cheap capacity. Self driving cars, I think. How important is it for


Londoners to have their own garden. Not at all. Concretely not. These


are the -- concrete the lot. These are the kinds of decisions that


politicians are making right now. How would you do the job. Available


housing has declined... The most popular job is marketing and PR.


Sorry, future London. I will have to have another go. Just before we


leave, one more example of the kind of data we are inadvertently giving


away two whoever might want to make use of it. Ladies and gentlemen, I


know where your cat lives .com. If you have uploaded a picture of your


cat and used a hashtag, #cat, you might be on this map. You have been


warned. Hello. Welcome to the weekend


but what a wild and windy start.
