How to write machines

Maths fun was had by all

Last weekend I was in Gothenburg at the incredibly inspiring Free Society conference FSCONS. Of course I was talking about mathematics, specifically how to get people learning it through fun, rather than “because it is useful”. My talk was called “Street Maths” (click for slides).

In discussions with many including Smári McCarthy and Marcin Jacubowski the idea developed further and one result is this (highly opinionated ;) manifesto for literacy.

In 1964 Paulo Freire was arrested and exiled from Brazil for teaching peasants to read. Both sides recognised the power of literacy, as a threat to oppression and a path towards a better life for individuals.

Today in the developed world we take it as an essential. Those who cannot read are not merely marginalised but kept out of society. Yet new skills are becoming necessary. Our formal interactions are now almost more likely to be through a computer than a pen. This change is sweeping through so fast that it can be hard to keep up. We have all joked that the kids teach the adults how to use the latest device.

Lets give the education system its due. The schools curriculum in the UK recognises that for Information and Computer technology (ICT):

…creative and productive use of ICT an essential skill for life.

National Curriculum (ICT) Key Stage 3

How do they suggest we try to achieve this?

The study of ICT should include:

  1. use of a range of information, with different characteristics, structures and purposes, and evaluation of how it matches requirements and its fitness for purpose
  2. use of a variety of information sources, including large data sets, in a range of contexts
  3. use and review of the effectiveness of different ICT tools, including a range of software applications, in terms of meeting user needs and solving problems
  4. developing an understanding of the need to:
    * employ safe working practices in order to minimise physical stress
    * keep information secure
    * manage information organisation, storage and access to secure content and enable efficient retrieval
  5. the impact of ICT on individuals, communities and society, including the social, economic, legal and ethical implications of access to, and use of, ICT.

National Curriculum (ICT) Key Stage 3

Think about these for a second as we consider the skill of literacy. It has two parts. Reading is of course important, but teaching people to read only allows one way communication. We also teach to write. We are taught to use written content, but also to create it. Think about this as you again read the list above. It only talks about learning to “use” ICT.

We need the skills to write and create as well as simply use.  Firstly, for some a bright idea will result in a new use for computers. Just as for some the ability to write leads to a published book. For others some simple creations will help their lives or those close by them, just as some write diaries. Finally there are many who do not write much at all. Yet learning to write writing still helps us develop our reading. The same is true for technology, but it is even more essential. Reading is a fixed skill. A language develops too slowly for reading skills to need much change. This is not the case with computers. The skills to use a particular piece of software can change with a single upgrade, even when we are not forced to change to a more advanced competitor. The usage skills therefore can easily go out of date. The more fundamental skills teach not just the skills to create but the ability to learn; to adapt to rapid changes.

So what skills are needed to create technology? Programming is obviously first. There is, however, a lot more to technology than computers. There are a vast number of ways that gadgets can be used, and will be used. Should we leave people waiting for someone else to make something close enough to what they need? What about adding the basic skills to make things?

Unlike literacy and use of computers these are not new skills. They are in fact ancient. Not a very long time ago if you wanted something you either had to make it yourself, or go to someone who could make it for you. Then we had the industrial revolution. The economy of scale. We came to rely on factories. This now goes so deep we hardly think of making something ourselves. For truly mass items like a hammer or a car, we are probably right.  What about a more specialised device though, like say a tractor? Or a 3d printing machine? Here plans are freely available that require some skill, but not expertise, to build. Including money for building time the product can be made for a fraction of the cost (in many cases 1/10 or less).  Even better, with such open design comes a powerful new option. Take the generic solution and adapt it to your own situation.  With time the design improves as individuals using it make refinements and add options. To do this takes a certain mindset and some basic skills.  A literacy of making.

The natural response to this is that, on top of the skills, tools are required and those tools are themselves prohibitively expensive. Though this is true right now, it is changing. Movements such as FabLabs and Hacker spaces have the tools and make them available for free, or at a small cost.  Even better, the machines can be part of the change.  One of the machines above is a 3d printer, this is not just cheap to produce, it is capable of making itself. The development of other machines has begun, with the ambitious goal of creating a RepLab a multipurpose factory that can create itself at a cost of less than $10000. Even commercially the machines only cost about $100000. Things are changing. Fast. The question is can we get the people in place with the creativity and skills to take full advantage of them?


Future of the LMS

June 4, 2009

I have just posted on the Save the LMS blog. I will repeat it here. A little bit of back story. Towards the end of last year the leaderships of the London Mathematical Society (LMS) and the Institute of Mathematics and its Applications (IMA) announced they would be merging to form a unified mathematics society. This was the first that I had heard (as an LMS member), but I will admit that I often do not follow these things closely.  This year a movement formed within the LMS to vote against the merger, eventually being sucessful at a second SGM, you can read notes on the meeting here and here.

Now for my thoughts on what happened and what needs to happen:

I am a younger mathematician and a proud member of the LMS.  My initial feeling on hearing of the merger was a slight sadness at the loss of tradition, with an acceptance that things sometimes have to change. Perhaps at this moment mathematics might be better served by a single organisation. To close something that has survived a long time, however, requires a higher level of argument. One should be convinced that it will never be of use. Not that it is the preferred tactical option, in the current situation. Though many good arguments were made for the merger they did not convince me to this high standard and so I voted against.

At this stage the debate was still quite reasonable. Through the referendum and the two meetings however something has gone horribly wrong.  I am going to be blunt. One of the key points in this debate is how best to present mathematics to government. If we try to do that with the blinkered and unsubtle approaches that appeared in some of this debate we are in trouble.

It is true that mathematics needs representation, but we should think about why that is. Is it because we want to keep nice cushy jobs playing with puzzles?  Or is it because we feel that mathematics is of value to society and humanity? If it is the second then we should be careful about changing. Especially to accommodate what we think outside voices might want. Instead we should have faith in the value of what we have, but get as many voices as possible selling it. I wrote in the IMA’s Mathematics Today about the responsibility mathematicians have to take our skills into wider science.  There are currently far many more exciting opportunities for mathematics than there are dangers.

This goes beyond talking to academics in other departments, however. Below all the hype of the internet it is slowly changing the way we communicate.  Nobody knows exactly how this will work out, but it is likely to lead to wider participation. This decentralisation of information will reduce the importance of central voices talking to the “right” people. We need to be careful not to be fighting the old battles. The more people who know the importance of mathematics the better. To achieve this we do not need one unified big voice, we need one million small voices.


Twitter

My first week on twitter from socialcollider.net

It took me a lot less time to get into twitter (@gelada) than to get a blog. However in general it is said that cycles of social media are getting faster. I realised that part of my problem, and a general problem when I look at communities online, is a fear of breaking social conventions I am not aware of. This probably comes from my English heritage.

It is not enough to be aware of this. In fact rationally I am perfectly aware that there are almost certainly no clearly established twitter conventions. A good example is how many tweets are acceptable in a day. Everyone has a certain level and I occasionally get irritated by some of the people I am following who over-post. In particular, I feel that it is at least bad style to post more than one tweet together to say something. The brevity is the key to the medium. Of course I have already broken this, which is why I say it is bad style rather than bad manners. A rule of style can be justifiably broken, however that should be thought about. It is up to my followers to decide whether the style decision I made was good or bad for them. If I make too many bad decisions they can move. That in the end is the essence, twitter currently works wonders in finding small niches. Finding the people who interest you deeply, rather than sticking with the mainstream media which have to interest a lot of people a little.

This actually leads to a fear to me. Will the growing ease of connecting to people make the process too efficient? This, combined with the firehose nature of twitter, is something I will have to negotiate with my dwindling supply of willpower. I need to make sure that I do continue to get things done, rather than get overwhelmed by potential ideas and contacts.

So the fact that I could (almost too easily) connect with interesting people on twitter (and the fact that they were there) has dragged me in. What am I going to do with it? I am not yet sure what style of tweeting I will adopt, or more deeply as Paul Prudence points out, what personality will emerge.  I am trying to stay away from too many funny comments as I feel that a) there is already plenty of this, and b) friendly feedback from my nearest and dearest has pointed out that I my funny comments are not generally considered so.  I do not promise to have no such comments, however! I started by thinking about the literary possibilities, in particular a haiku-like form, 5 sentences with 30, 29, 28, 27 and 26 characters.  I am not sure, however, that twitter is the best place for literary effort.  Though in another aspect of personal style I prefer to use full sentences and punctuation, as I attempt to in text messages.  So the best way to find out what I am doing is to look back at what I have said. There will probably be a lot on mathematics and art, with the smattering of comments on how to improve the world, and the occasional monkey joke.

So, thanks for reading and please let me know if I offend or break your personal style rules. I might not change anything but I would be interested to know.

Finally on language, when I started to write these pages I complained about the language. I simply do not like the words blogging and blogs.  To show that I am not always a language fuddy-duddy, I will say that twitter and tweet I accept wholeheartedly.

PS, why does twitter need to be centralised? Will this version be scalable? Personally for several reasons I would prefer a radically localised version, this should be about connections between individuals and small groups, not how we all plug into the same big machine.


Unscheduled Post: Niches and responsibility

April 11, 2009

There has been a recent blog discussion on the topic of attribution.  As a piece of plankton (not even a small fish) in this world I only suffer from the occasional automatic link farm reference.  However this is a debate worth having, with good posts from Andy Baio and Jason Kottke which both have long comments discussions.  Merlin Mann on 43 Folders took the ball from this and started to run:

The niche is the thing, friends. It’s the future, and it’s here. Things like this little rhubarb are just the earliest Braxton Hicks contractions of a change that will be getting way, way weirder than most people think.

But, if we each have the arrogance to demand the credit that we’re due, an astonishing number of opportunities begin to unfold. We learn who really made what we love; not just who put it someplace where lots of people can see it. We discover whom we admire and we make decisions about who to collaborate with.

Merlin Mann, Free as in ‘Me’

When I started this blog I put up a post about why.  The desire to put something out there, to say things I thought were important and hope that they manage to find the people who are interested in them.  Though I have become comically addicted to watching the rise of my rather small page views, I try not to chase them.  I know that it makes a huge difference not just who the people looking at the site are, but how they react.  If I can change a few people’s opinions about mathematics in a small way my work is worthwhile.  The difference between this metric and the page views is that it is very hard to measure.  Am I putting in a lot of effort to words that are never truely read?  As an academic of course I am used to this, but at least published papers look good on my CV.  

So I am proudly preaching to my own tiny niche.  Why do I think that niches are important?  Moving away from mainstream to a world of overlapping niches, we can admit  that there is no “real world”.  The one that people regularly accuse others of not living in, but rarely say about themselves.  In collecting their own personal collection of niches people have to ask questions about who they are.  Hopefully (I put my utopian hat on here) this will lead to an increase of the attitude that whatever one does it should be done well.  This includes consuming.  Taking the time to find out where things (from food to blog posts) come from.  Thinking about things, not just taking the convenient whether convenience is the cheap item or the easy opinion.  Maybe, just maybe niche blogs and easy publication can help some of these things grow.  

I will admit a slight hidden agenda in posting this.  I have been a fan of 43 folders for a long time, and almost worshiper of Merlin Mann since the change of direction.  His post has already attracted over 4000 comments so I doubt he will actually read this, but I can hope!  One criticism though Merlin, saying something is a polemic is just as much a sign of “people who think they are clever” as saying it is a rambling rant.
