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

:00:00.:00:00.

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

:00:00.:00:24.

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

:00:25.:00:48.

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

:00:49.:00:55.

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

:00:56.:01:04.

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

:01:05.:01:11.

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

:01:12.:01:29.

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

:01:30.:01:32.

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

:01:33.:01:40.

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

:01:41.:01:44.

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

:01:45.:01:51.

bitcoin. These are where the bitcoin transactions are happening around

:01:52.:01:54.

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

:01:55.:02:00.

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

:02:01.:02:05.

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

:02:06.:02:10.

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

:02:11.:02:16.

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

:02:17.:02:21.

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

:02:22.:02:25.

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

:02:26.:02:30.

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

:02:31.:02:35.

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

:02:36.:02:40.

also beauty in how the bitcoin currency works and how transactions

:02:41.:02:44.

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

:02:45.:02:49.

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

:02:50.:02:53.

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

:02:54.:03:00.

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

:03:01.:03:04.

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

:03:05.:03:10.

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

:03:11.:03:14.

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

:03:15.:03:19.

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

:03:20.:03:22.

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

:03:23.:03:29.

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

:03:30.:03:33.

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

:03:34.:03:39.

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

:03:40.:03:43.

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

:03:44.:03:46.

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

:03:47.:03:53.

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

:03:54.:03:56.

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

:03:57.:04:02.

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

:04:03.:04:07.

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

:04:08.:04:11.

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

:04:12.:04:16.

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

:04:17.:04:21.

few. I think the block chain to me is all

:04:22.:04:32.

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

:04:33.:04:37.

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

:04:38.:04:44.

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

:04:45.:04:49.

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

:04:50.:04:54.

can facilitate and trust amongst individuals, governments,

:04:55.:04:59.

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

:05:00.:05:06.

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

:05:07.:05:10.

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

:05:11.:05:19.

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

:05:20.:05:23.

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

:05:24.:05:28.

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

:05:29.:05:33.

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

:05:34.:05:37.

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

:05:38.:05:42.

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

:05:43.:05:46.

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

:05:47.:05:51.

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

:05:52.:05:55.

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

:05:56.:06:02.

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

:06:03.:06:07.

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

:06:08.:06:11.

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

:06:12.:06:15.

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

:06:16.:06:20.

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

:06:21.:06:24.

in general will start floating away as we get governments,

:06:25.:06:28.

institutions, individuals, businesses and enterprises to be

:06:29.:06:31.

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

:06:32.:06:35.

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

:06:36.:06:38.

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

:06:39.:06:42.

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

:06:43.:06:48.

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

:06:49.:07:00.

are seeing new technological eras that are as different from each

:07:01.:07:03.

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

:07:04.:07:07.

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

:07:08.:07:14.

exact utopia for your political ideology but it does make

:07:15.:07:21.

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

:07:22.:07:24.

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

:07:25.:07:29.

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

:07:30.:07:33.

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

:07:34.:07:37.

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

:07:38.:07:43.

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

:07:44.:07:48.

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

:07:49.:07:53.

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

:07:54.:07:56.

technology that might change society, the benefits are clear to

:07:57.:08:01.

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

:08:02.:08:07.

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

:08:08.:08:12.

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

:08:13.:08:16.

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

:08:17.:08:20.

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

:08:21.:08:23.

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

:08:24.:08:30.

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

:08:31.:08:37.

will create viruses that will attempt to accumulate economic

:08:38.:08:42.

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

:08:43.:08:45.

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

:08:46.:08:56.

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

:08:57.:09:04.

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

:09:05.:09:10.

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

:09:11.:09:14.

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

:09:15.:09:18.

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

:09:19.:09:22.

It was also the week that the internet sensation Psy released

:09:23.:09:27.

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

:09:28.:09:36.

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

:09:37.:09:41.

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

:09:42.:09:45.

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

:09:46.:09:49.

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

:09:50.:09:55.

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

:09:56.:10:02.

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

:10:03.:10:08.

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

:10:09.:10:16.

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

:10:17.:10:19.

movements which could contribute to its future intergalactic missions.

:10:20.:10:24.

Not quite ready for a Strictly just yet.

:10:25.:10:29.

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

:10:30.:10:36.

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

:10:37.:10:44.

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

:10:45.:10:51.

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

:10:52.:10:56.

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

:10:57.:11:00.

some of the masks designed to defeat facial recognition software,

:11:01.:11:06.

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

:11:07.:11:10.

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

:11:11.:11:18.

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

:11:19.:11:23.

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

:11:24.:11:29.

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

:11:30.:11:35.

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

:11:36.:11:42.

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

:11:43.:11:49.

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

:11:50.:11:54.

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

:11:55.:11:59.

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

:12:00.:12:09.

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

:12:10.:12:12.

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

:12:13.:12:18.

the course of the exhibition, getting better at finding those

:12:19.:12:20.

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

:12:21.:12:28.

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

:12:29.:12:33.

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

:12:34.:12:37.

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

:12:38.:12:40.

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

:12:41.:12:57.

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

:12:58.:13:03.

work, helping us to get clearance from individual stock exchanges

:13:04.:13:07.

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

:13:08.:13:13.

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

:13:14.:13:20.

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

:13:21.:13:24.

stars clustered together based on correlations between companies, the

:13:25.:13:32.

market had collapsed and all the companies had dropped their prices

:13:33.:13:35.

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

:13:36.:13:38.

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

:13:39.:13:50.

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

:13:51.:13:59.

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

:14:00.:14:01.

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

:14:02.:14:20.

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

:14:21.:14:23.

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

:14:24.:14:27.

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

:14:28.:14:33.

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

:14:34.:14:42.

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

:14:43.:14:48.

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

:14:49.:14:54.

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

:14:55.:15:00.

breathing patterns. And then some clever algorithms identify your

:15:01.:15:04.

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

:15:05.:15:10.

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

:15:11.:15:14.

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

:15:15.:15:21.

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

:15:22.:15:25.

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

:15:26.:15:29.

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

:15:30.:15:38.

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

:15:39.:15:43.

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

:15:44.:15:48.

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

:15:49.:15:56.

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

:15:57.:16:04.

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

:16:05.:16:09.

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

:16:10.:16:14.

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

:16:15.:16:17.

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

:16:18.:16:23.

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

:16:24.:16:26.

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

:16:27.:16:33.

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

:16:34.:16:42.

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

:16:43.:16:47.

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

:16:48.:16:52.

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

:16:53.:16:58.

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

:16:59.:17:07.

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

:17:08.:17:12.

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

:17:13.:17:15.

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

:17:16.:17:18.

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

:17:19.:17:31.

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

:17:32.:17:38.

has exploded and, counterintuitively, how little space

:17:39.:17:44.

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

:17:45.:17:54.

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

:17:55.:17:59.

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

:18:00.:18:03.

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

:18:04.:18:06.

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

:18:07.:18:13.

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

:18:14.:18:21.

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

:18:22.:18:29.

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

:18:30.:18:34.

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

:18:35.:18:40.

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

:18:41.:18:47.

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

:18:48.:18:52.

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

:18:53.:18:58.

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

:18:59.:19:04.

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

:19:05.:19:11.

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

:19:12.:19:26.

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

:19:27.:19:42.

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

:19:43.:19:48.

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

:19:49.:19:54.

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

:19:55.:19:57.

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

:19:58.:20:02.

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

:20:03.:20:08.

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

:20:09.:20:14.

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

:20:15.:20:19.

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

:20:20.:20:23.

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

:20:24.:20:31.

democratise data and make it accessible to everyone and we do

:20:32.:20:36.

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

:20:37.:20:40.

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

:20:41.:20:47.

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

:20:48.:20:54.

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

:20:55.:21:01.

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

:21:02.:21:09.

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

:21:10.:21:17.

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

:21:18.:21:22.

piece looks at telling everyone across the exhibition what data is

:21:23.:21:26.

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

:21:27.:21:36.

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

:21:37.:21:42.

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

:21:43.:21:47.

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

:21:48.:21:55.

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

:21:56.:22:01.

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

:22:02.:22:06.

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

:22:07.:22:10.

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

:22:11.:22:13.

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

:22:14.:22:19.

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

:22:20.:22:25.

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

:22:26.:22:28.

is to make a series of infrastructure changes based on the

:22:29.:22:33.

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

:22:34.:22:41.

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

:22:42.:22:46.

What kind of transport will you prioritise, where will resources

:22:47.:22:50.

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

:22:51.:22:52.

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

:22:53.:22:58.

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

:22:59.:23:02.

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

:23:03.:23:07.

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

:23:08.:23:17.

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

:23:18.:23:24.

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

:23:25.:23:30.

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

:23:31.:23:35.

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

:23:36.:23:40.

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

:23:41.:23:43.

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

:23:44.:23:57.

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

:23:58.:24:08.

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

:24:09.:24:12.

warned. Hello. Welcome to the weekend

:24:13.:24:32.

but what a wild and windy start.
