Climate change - An update

There is really no room for doubt that we are affecting the world's climate in a wide variety of harmful ways. BBC news item on the Met Offfice reportA new report from the Met Office finds the evidence has stacked up even more strongly since the IPCC report in 2007. Read the BBC's news item on the Met Office report.

There's more Met Office information on their climate change page. Well worth a look if you want to know more.

(This update is intended to add new information to my earrlier blog 'Climate change - Truth or deception?')

The Human Genome Project - Ten years on

The first human genome was sequenced ten years ago. Replication of the DNA helixIt was a huge and expensive project that could be repeated today 500 times as fast at 100 000th of the cost. That's an indication of the rate of change of sequencing technology.

But what benefits has the project brought?

A very great deal! In the studies of diabetes and obesity alone, the existence of the sequence has enabled much more rapid progress in research and this will feed into improvements in medical treatments more and more in the future.

But there are still considerable areas where we lack understanding and larger scale studies sequencing the genomes of thousands of people are now underway. These will hopefully fill in further gaps in our knowledge and set the scene for even more novel and useful treatments in future.

For more detail, read Jonathan Wood's post on Oxford University's website.

Climate change - Truth or deception?

Most scientists are agreed, we have a serious problem on our hands. A typical glacierPossibly less severe than we fear but just as possibly more severe than we fear. Meanwhile there are plenty of sceptics who claim the data has been fixed or incorrectly analysed.

It's no good speculating and it's no good just crossing our fingers. We need to know whether the science is sound or not. It makes a difference. Do we need to stop releasing CO2 and methane or can we safely continue as we've been going?

Whichever side of the debate you are on, I strongly urge you to take a good look at Dan Satterfield's latest blog post. He has no doubt which side he is on. I agree with him and I really want to encourage everyone to read his post and its two main references and draw their own conclusions. This is one of the best posts on this topic that I have seen.

USA thinks open source is piracy!

Now here is a very strange thing. It seems that the USA considers Canada to be guilty of a sort of intellectual property theft, Free Software Foundation emblemor if not exactly theft then at least some sort of underhanded anti-competitive practice.

The argument seems to be that if I write a piece of useful software and decide to give it away instead of selling it, I somehow undermine free enterprise. So things like Linux, Wikipedia, Media Monkey, the Gimp, Microsoft Bing, Google Maps, and thousands of other items used daily by millions of people are undermining free enterprise.

No. I must have misunderstood. Surely?

Well, take a look for yourself.
What is going on here? I mean - really? It will all be sorted out quite quickly once the Office of the United States Trade Representative thinks it through more carefully, right?

I thought the USA stood on the side of freedom. So if I write some software, or a book, I can give it away if I choose to do so. And if I want to use free software written by someone else I may do that too. How would that 'undermine intellectual property rights'?

I must have missed something...

Has the GNU project missed it too? Is Linux in the wrong? And Ubuntu? What about Open Office? Scribd? Wikipedia?

Has anyone told the Free Software Foundation?

UPDATE - Better Place rolls out first trial

Here's the latest on Shai Agassi's Better Place company. The trial rollout of a few hundred cars has begun in Israel.

The TED Conference - Microsoft's mapping

Microsoft seems to be making great strides with online mapping and the integration of such things as user imagery and even live video. Fascinating to see how they're tying it all together in a most remarkable way.

Blaise Aguera y Arcas demonstrates some of this stuff at the TED conference.

Shai Agassi - Joined-up thinking

Shai Agassi, the Israeli/American alternative energy entrepreneur is thinking big. he can't help it, it's in his nature! Better PlaceThe most valuable things he has brought to the table involve lateral thinking, sudden leaps that change everything, paradigm shifts.

Where most of us are content to tweak the status quo, Shai Agassi understands that to make a real change we need to look at our problems with open minds, recognising that the solutions may sometimes be there right before our eyes but that 'tweak the status quo' may blind us to them. We often look without seeing.

Shai's solution to battery powered motoring is close to rollout in a major way, first in Israel, then Denmark, then Australia, and with a range of other places queuing up to follow the lead of these three. Banks are beginning to believe in the business model of his company, Better Place, and are starting to provide loans to enable the infrastructure to be built. Governments are also backing the idea with funding. Car manufacturers, electricity companies and even oil companies and chains of petrol stations are joining in too. This is an idea that is starting to fly.

But if that's not enough, Shai Agassi is also pointing out that we need joined up thinking on electrical energy. Wind farms, electric motor vehicles, battery exchange systems all face issues, but build them all on a large scale and they help one another out in significant ways.

Listen to Shai as he explains.



You can also watch Shai explain his battery swap technology (recorded in 2009).

Demolishing the old office - the video

A few days ago I promised you a video clip of the demolition. Here it is. This clip shows the hydraulic crushing jaws at work on a steel reinforced concrete floor in the building that once included my office.



It's an extraordinarily quiet way to bring down a building, there is no loud noise, no great vibrations underfoot as large pieces of masonry come down. It's all crushed in situ and the pieces that fall are relatively small. There is awesome power in these steel jaws. The machine eats through concrete like a child nibbling chocolate.

Linked Data - queryable, extensive, public data

Tim Berners-Lee has done it again. This time it's not about hyperlinked text but about queryable data. In many ways this can be seen as the public domain, social software equivalent of Stephen Wolfram's proprietary system, WolframAlpha.

It's not hard to see that open will win out over proprietary once again.

Take a look at ReadWriteWeb's post on this topic. It's an excellent roundup. They recommend starting with Tim Berners-Lees's breathless presentation at TED, so do I. I've embedded it below for convenience. Then take a look at the DBpedia website to see how you can use the material for yourself. An online paper presents the technical aspects.

Awesome video, great music, astonishing machine

Here's a fine video beautifully put together with excellent music and sound effects. Mike Interbartalo edited imagery of the Space Shuttle launch process from beginning to end. It really is an experience to watch and listen, even if you're not much interested in space or rockets.

It's strange to think that next year the Space Shuttle will fly for the very last time and there is nothing in place to take over. The USA will no longer be able to launch crewed vehicles into orbit.


STS-129 Ascent Video Highlights from mike interbartolo on Vimeo.

For anyone wanting a bit more detail, you will see the Shuttle stack on the giant tracked platform arriving at the launch pad. There are some details of the engine ignition sequence, the three main engines first, then the solid rocket boosters. You will see the solid boosters fall away and splash down under their parachutes ready to be collected by boat and returned for re-use. You will see the giant external tank released to return to a fiery destruction in the atmosphere. And then finally the shuttle itself heads on into Earth orbit.

There are shots from many angles here. Some from the ground or from the air, some from cameras mounted on the solid boosters, the external tank, and the shuttle itself.

The coming of the electric car

I didn't know that Shai Agassi had spoken at TED until I read about it today on the Tiny Car| Smart Car News Blog. Shai's company, Better Place, is rolling out fully green, all electric cars and the infrastructure to support them. The plan is that they should be cheaper and more convenient than petrol cars. Quite a challenge!

Here's the video of his talk at TED, it's inspiring and convincing and describes an approach that is simple but original. My own belief is that this idea will fly - it deserves to. Watch and see.

Testing Google Wave

I had an invitation from Google to join their Wave preview, and very nice it is too. I invited the limited number of friends I'm allowed and started waving with them, Google Waveand we did a lot of the instant messaging things that I imagine most people will begin with.

But then I wondered how Wave would work in 'email' mode. The text that follows is copied straight from the Google Wave interface and pasted here. It explains some interesting thoughts that came to me as I wrote my first extended item in Wave.

Note: The 'wave address' in the footer won't work with Wave. It's just represented as an email address. I have no idea how Google will arrange mail to wave connections. But I'm confident that Google has already thought this through, at least in principle.


Using Wave like email - 9:25 am

Hi everyone,

This is my first attempt at using Wave in an email-like fashion. So far we've done quite a bit of instant-message-style waving, but I have a sense that the email approach will feel very different.

Thinking about it all while making the morning cuppa for me and Donna I could see that 'email' would be different (some of my best ideas pop into my head in embryo form at the kitchen sink or weeding the garden or emptying the cat's litter tray).

For one thing it answers a question we'd already pondered. Why have Google given us @googlewave.com addresses, why not use @gmail? Well, I think the answer may simply be that if Wave did have IMAP, SMTP and POP extensions, the new addresses would allow outsiders to email us and the mail would appear in our inboxes as a blip (albeit a large one like the one I'm typing now). And we could send a long blip to a non-Wave address and have it delivered via the SMTP extension. This makes a lot of sense to me. I hope they enable it quite soon, it would make it possible for a user to move entirely from email to Wave.

What other thoughts occur to you guys about the email 'mode'. I think the entire approach of wave is very clever, that a single system can be used in so many different ways. A real breakthrough. And it is probably going to be one of those disruptive innovations that we'll all take for granted in the end. A real brainwave on Google's part to make it both open and extensible and to offer their own client and server code free to everyone to run on their own hardware as well.

One other observation. When I created this wave I just closed the box that lets you select contacts for the wave. So I'm alone in this blip as I type it. When it's finished I'll drag in the contacts I want to send it to. That makes it feel even more email-like.

And I used the first blip as the title with this large, second one as the body. It works well like this.

What do you guys think?

Chris

PS - For fun I cut and pasted my email footer below. Then I added my wave address and made my mail address into a link. It seems so 'normal' like that. And anyone could add a wave address to a real email footer so wavers could click it. Excellent.

PPS - I just found a typo and fixed it - and then added this PPS. You can't do THAT in email!

Electric car - Better Place video

The company that just might get electric vehicles on the road in a major way, 'Better Place', has released a video showing the system in action.



With Israel, Denmark, and Australia rolling out the scheme, and with both Nissan and Renault on board to manufacture the cars, it seems this idea may well be starting to get some traction - (pun intended :-)

See also my earlier blog entry about this system and the guy behind it, Shai Agassi.

The electric car - but better?

Shai Agassi through his company, Better Place, has developed a system for building and operating electric vehicles - and it might just work. He claims that the car would cost less to buy and be more convenient to use than a Shai Agassi speakingnormal petrol powered car. And the cost per mile would be similar to current fuel costs.

Shai has thought this through in great detail and has persuaded companies (Renault and Nissan) and governments (Israel, Denmark, Australia for example) to make a start on building the necessary infrastructure and the new vehicles. He is a visionary but he also has business acumen, drive, enthusiasm, and good persuasive speaking ability.

Very, very interesting, and well worth watching the video. You will have to watch the sponsor video first (amusingly enough it's for an oil company) but then you can choose individual segments for yourself.

A free vote?

Here are the crowds in Tehran, protesting about the election results. Crowds in Tehran protesting about the electionThis picture was posted on Twitter just a few minutes ago.

Read the latest news from Tehran as it develops on Twitter. Some of the streams of tweets are coming from people on the streets in Tehran, posted from mobile phones (this guy deserves a medal but is probably in line for something much harsher). Others are comments from others not involved in the protest. And then there are also comments, good wishes, prayers, and thoughts from people world wide.

There are more photos online, and the major news channels have reports, for example the BBC. It'll be all over tomorrow's front pages for sure.

Live news reporting is one of the things that Twitter does best.

The Internet Protocol

Did you know that your connection to the internet is dying on its feet? Honestly, it really is! Diagram of part of the internetAnd the consequences are simply horrendous. 'The Internet Protocol' sounds like a film title, but it's the name of an important underlying mechanism that is the foundation of email, web browsing, and much, much more.

Most of the world's computing devices are using version four of this protocol (IPv4). Its replacement, IPv6, was introduced more than a decade ago to provide a huge increase in the number of available addresses and a raft of improved functions including assured service quality, security, and more.

What does it all mean? - You might like to read what Carl Bialik of 'The Wall Street Journal' has to say on the subject. Hint, read the comments as well, some of them are illuminating.

Carl writes...
The increasingly crowded Internet [is] running out of Internet Protocol addresses, used to identify computers and Web sites on the network.

He quotes industry experts as saying...
The chaos that follows is difficult to predict. (Tony Hain - IPv6 Forum)

Individual users may not be able to view websites and communicate with certain Internet destinations - Corporations may not be able to communicate with certain critical government resources, clients, and potential customers - Governments may lose the ability to see and communicate with the 'whole Internet' - Citizens may not be able to access government information online (John Curran - American Registry for Internet Numbers)


And readers comment...
Internet technology was one of the last areas that the U.S. was a leader in, and that has now disappeared. (Lawrence Hughes - InfoWeapons)

There is the potential for big disruptions unless more enterprises and the public sector begin migrating. (Jennifer Geisler - Cisco)


The Wikipedia article on IPv6 explains that it was selected as the successor to IPv4 in 1998, and takeup at the end of 2008 was estimated as follows - Russia 0.76%, France 0.65%, Ukraine 0.64%, Norway 0.49%, United States 0.45%. Asia leads in terms of absolute deployed numbers, but the relative penetration was smaller (e.g., China 0.24%).

IPv4 addresses are expected to finally run out in 2010, or possibly 2011. We have very little time.

There is no excuse for the slow rollout, IPv6 is available on all major operating systems in use in commercial, business, and home consumer environments. IPv6 networking gear has been increasingly available for many years.

How will this affect the end user? - At worst, large chunks of the internet will be unreachable. It will be as if those countries and companies don't exist.

However, it's likely that losses of connectivity will begin slowly and then accelerate. This might increase the sense of urgency as customers begin complaining to their service providers.

Sections of the internet where IPv6 is not yet supported will become islands of poor and incomplete service and will be increasingly isolated and unusable. IPv4 is likely to wither away, but it may take a long time to disappear completely.

With less than 1% of the network already converted and less than two years remaining before we start to see a real impact, anyone who can influence the rate of IPv6 uptake should begin lobbying hard right away.

Wolfram Alpha

Wolfram Alpha is about to hit the streets (or at any rate, a computer screen near you). The Wolfram Alpha query screenCreated by Stephen Wolfram and his company, Wolfram Research, it will look superficially like a search engine but is fundamentally different in nature.

Like a search engine it comes with a text entry box where you can type in a query, like a search engine it goes away and thinks and then spits out results on a webpage. But what goes on behind the scenes and the nature of the returned webpage couldn't be more different.


Wolfram Alpha depends on two earlier developments from the same stable. Mathematica is software that enables mathematical manipulations to be entered, processed, and displayed on a computer, while NKS (which stands for 'A New Kind of Science') is an alternative to the normal tools used by scientists to model the way the universe works.

Using both of these innovative tools, Wolfram Alpha takes a free text query, decides what the user wants to know, looks up the relevant information in its enormous collection, processes the information to create an answer to the original query, and builds a webpage on the fly to display the response. The webpage may include text, images, graphs and charts etc. The end result is a tailored report that might have been written by an expert. Indeed, in many ways Wolfram Alpha is an expert!

Steven Wolfram is an extraordinary person. He is, frankly, a genius - one of a handful of truly great minds in our own time. He looks at things in new ways and comes up with fresh insights, testing them, proving them, and then publishing them. Here, in his own words, is how he's spent his life so far.

Major periods in my work have been:

• 1974-1980: particle physics and cosmology

• 1979-1981: developing SMP computer algebra system

• 1981-1986: cellular automata etc.

• 1986-1991: intensive Mathematica development

• 1991-2001: writing the book, 'A New Kind of Science'

(Wolfram Research, Inc. was founded in 1987; Mathematica 1.0 was released June 23, 1988; the company and successive versions of Mathematica continue to be major parts of my life.)


You can see right away that he is not a man in a hurry. He is not afraid to spend five years or more on a single project. Learn more about his background and work from Wikipedia.

Not everyone agrees with Wolfram's work on NKS, a range of reactions are included in the Wikipedia article on the book.

In the end, 'wait and see' may be the best advice for both Wolfram Alpha and NKS. As far as Alpha is concerned, we'll all get a chance to try it and draw our own conclusions when it's released. Hopefully that will be next month (May 2009).

Meanwhile you can watch video of Stephen Wolfram demonstrating the new technology at Harvard on 28th April.

For news about the new tool, take a look at the Wolfram Alpha Blog which will be updated regularly with further announcements and background information.

Helping the helpless

Imagine this - you are a tailor in a village in rural Ghana, you have little income, just enough to scrape a living. Precious spectaclesAs you reach the ripe old age of 35 your eyes deteriorate and you can no longer see to thread the needle on your sewing machine. You are forced to retire.

The problem - a pair of glasses would solve the poor sight but there's no optician anywhere nearby and even if there was, you couldn't afford to pay him.

This is a true story. The man in the photo is African, a Zulu, his life has perhaps been transformed by the glasses he's wearing. The Ghanaian tailor's life was transformed in the same way. Perhaps it's not quite true to claim that 'they were blind, but now they see' but it's no exaggeration to say they were short sighted but now they see clearly, clearly enough to be able to read, and work, and earn an income.

The availabilty of cheap but effective glasses can transform individual lives and even entire communities. But there's a serious snag. Glasses are expensive for two reasons, first you must obtain a prescription to suit your eyes, and then you have to pay for bespoke lenses made to match the prescription. Opticians and optical labs are expensive, far too expensive for an African or Indian villager.

The solution - enter Josh Silver, an Oxford physicist. Thinking about this problem he hit on the idea of creating special glasses that each person can adjust to suit their own eyes. Now he's getting help to roll them out on a larger and larger scale.

An article in last month's Guardian (Inventor's 2020 vision) explains how the invention was made, how it works, and how it's being scaled up to help millions, hopefully even billions. It needs powerful sponsors in industry and government but that support is beginning to appear. The future looks promising; not least for the world's short-sighted poor.

The Antikythera Mechanism

The heavily corroded remains of an intricate and strange looking mechanism were found in 1901 in a Mediterranean shipwreck. The calendar dial of the deviceSixty years later after painstaking cleaning and study, it emerged that the device was a mechanical analogue computer for predicting the movements of the sun and moon in the sky. Various replicas have been built based on the known features of the mechanism.

The Antikythera mechanism makes it abundantly clear that the Greeks were advanced, not only in their scientific knowledge, but also in their mechanical technology. Reports from ancient writers like the Roman author, Cicero, describe mechanisms such as Antikythera. But until the corroded remains were recovered and studied these written accounts seemed fanciful. Surely the ancient world had nothing this advanced?

More recent studies have used high resolution X-ray tomography, and better reconstructions have become possible.

One of the later reconstructions can be seen working in the video below. If you view the video from You Tube you can switch to a higher resolution.



The X-ray tomography data has opened up a new window into the workings of the device. But it has also enabled historians to read a considerable amount of Greek text from the metal surfaces. This text consists partly of labels on the various scales and displays the mechanism used to present the positions of planets, calendar dates and so forth. The remainder of the text is a guide on how to use the device.

A great deal can be learned from the inscribed text. The names of the months varied from place to place in the ancient Greek world and this means we can determine its place of manufacture or intended use to be the central Mediterranean, not as originally supposed the eastern Aegean.

A longer and more technical video is presented on the Nature website (select the high resolution version and watch it in full-screen for the best view). There are also links to the Nature paper by Freeth, Jones, Steele, and Bitsakis, and a Nature news story (though there's a fee for the full text of these).

Wikipedia's article on the mechanism provides more detail for the average reader and has an excellent list of references, links, and suggested additional reading. One of the links is an article from New Scientist giving a good deal of background.

Science? Technology?

Hang on, there's something unusual here. There's a shiny stone in the ashes. He picked it up and blew off the dust, it seemed unusually heavy in the hand, Malachite, copper oreit was a strange shape, and its colour was unlike any rock he'd seen before.

He spat on it and rubbed it with his finger, then took it over to the brook and washed it. This was something special, he was was going to keep it. He slipped it into his leather pouch.


He thought about the fire. It had been fiercely hot where the wind had blown through a gap in the hearthstones, he'd noticed that last night. Fires were usually orange in the centre, this one had been a bright yellow, almost too bright to look at and much too hot to get close. Perhaps the extreme heat had somehow created this object? What else had been different?

Science or technology? -
What's going on in this little story? When is something science? When is it technology? What's the difference? Does it matter? There's popular confusion about these two words, not helped by the fact that some of our most respected sources are as confused as the general public.

But there's a perfectly clear difference between the two and it's really not hard to explain. We don't even need a scientist or a technologist to help us nail this one; a good place to start would be a dictionary. The Wiktionary definition offers two current meanings for the word 'science'.

1 - The collective discipline of study or learning acquired through the scientific method; the sum of knowledge gained from such methods and discipline.

2 - A particular discipline or branch of learning, especially one dealing with measurable or systematic principles rather than intuition or natural ability.

For technology, Wiktionary gives

1 - ... the study of or a collection of techniques.

2 - ... a particular technological concept - the body of tools and other implements produced by a given society.

We can see right away that science is to do with knowledge whereas technology is concerned with techniques. The difference is that science seeks to understand what is while technology has a purpose and wants to make use of what is.

Two things immediately follow from this. There can be no technology without prior science, and technological advance usually opens fresh opportunities for science.

Making a discovery - Let's take another look at our little story. During the Late Stone Age (the Neolithic) somebody must have noticed that a shiny material was left behind in the ashes of last night's fire. This is science, initially it's just a matter of observing what happens. Maybe copper had been accidentally extracted from pieces of ore many times before but very little attention had been paid to it. Only a particularly inquiring mind would notice and begin to wonder.

What if? - The next step is to test the possible causes for what we have observed. This is a scientific experiment. The man who found the special pebble might try to create a hot fire deliberately by altering the layout of the stones and the amount and kind of wood. He might play around with different kinds of stone. He might discover that he could make a fire hotter by rearranging things. He might also find the heavy, lustrous material only appeared when a very hot fire was combined with a particular kind of hearthstone. By trial and error and keen observation he might become quite proficient at producing copper.

Finding out how things work is science, using the knowledge to make copper on demand is technology. It would be worth making because people always like unusual objects, he'd be able to trade lumps of this stuff for food, stone tools, and other things he needed.

Science is a matter of observing, making hopeful guesses, testing ideas, and narrowing down the truth by ruling things out. Technology is a matter of seeing the value of something and finding practical ways of achieving it. Science may lead to new technology, and technology may lead to new industry. And existing technologies and industries may enable further scientific progress.

Long before copper was first extracted by fire, technologies based on wood, stone, skin, fibre, bone and other materials were well advanced. Homes could be built from mammoth tusks or branches cut from trees, the frames covered with sods of earth or foliage. Baskets, woven fabrics, and simple pottery were used for practical purposes and for decoration. And hunter-gatherer technology was well advanced with good strategies for finding edible roots, fruits, shellfish along with bows, stone-tipped arrows and spears and more.

Why does it matter? - We often say 'science and technology' in a single breath without thinking about the difference. Studying sub-atomic particles is science so we're tempted to think that a particle accelerator is science too. But the accelerator is technology. Because astronomy is a science we think that the Hubble Space telescope is also science, but it's not.

This confusion becomes a problem when we oppose science because we are anxious about technology. Science informs us about the universe in which we live, technology makes changes that often affect us in practical ways. It is never harmful to understand something, but it may be harmful to make use of it. The internal combustion engine is a great example. Understanding combustion, the expansion of gases, or the structural strength of materials does not in itself do either harm or good. But the technology of an engine can be used to power an armoured vehicle or an ambulance. It can be used to make war, deliver a car-bomb, or rescue a sick person. And as we all know it may also have unexpected side effects such as causing global warming, city smogs, and respiratory diseases.

We will all agree that a certain level of effort is useful, without science and technology we would still be living without clothes, without houses, without fire, and without medicine.

But blaming science for issues with technology is counterproductive. It's not what we know that gets us into trouble, it's what we do with what we know. But it's also true that our current technology has done untold harm. It has enabled unsustainable growth of population and comsumption of resources, we are now between a rock and a hard place.

The main issues with science are deciding how much of it we can afford and where to focus the funds and effort. There are also some regulatory issues, science depends on experimentation and experiments may raise moral issues. We sometimes disagree over what is acceptable.

The main issues with technology are how it will be used and how it will affect society and our environment. Meanwhile, neither science nor technology can address the great questions of purpose. Why are we here? Why is the universe here? What is the purpose of love? Moral issues, questions of right and wrong, value judgements, all of these must be handled in some other way.


Questions:

  • Your home is full of the results of technology. Can you identify some of them?
  • Can you make any guesses as to the kind of science that underpins those technologies?
