Unscheduled Post: Subtlety and swine flu

April 29, 2009

The difference between stupid and intelligent people–and this is true whether or not they are well-educated–is that intelligent people can handle subtlety. They are not baffled by ambiguous or even contradictory situations–in fact, they expect them and are apt to become suspicious when things seem overly straightforward.

Neal Stephenson, Diamond Age

The swine flu story is a great test of someone’s subtlety. You have to hold two competing possibilities in your head, both with serious consequences:

1) Nothing interesting is happening…

2) Millions are going to DIE!!!!!!

1 has the obvious cost of fiddling while Rome burns and avoiding doing easy things that make serious improvements down the road. 2 has the problems of panic, societal shutdown, economic issues, etc. Plus for the experts the cry wolf problem, next time people will revert to 1.

The problem is that, at the moment we cannot know quite what will happen, but 2 is a scarily real possibility.

Of course both of these options are better than the media’s version of events. Holding strong versions of both 1 and 2 simultaineously. They both make better stories than subtlety. Saying on the one hand that we are all going to die and on the other that nothing is going to happen. In CNN’s case hyping then accusing twitter of causing panic.

In fact for me twitter has connected me up to excellent information, even though there is plenty of denial and panic as well. With twitter I can choose who to listen to, tuning my own news sources, rather than the limited choice available in the mainstream media.  In particular @bengoldacre, is always a relaible source on stories involving science when it hits the news and on this issue @hexayurt was right on the money, especially with the flucode.  There are many more informed people out there talking sense through this topic.

This is sad as there are many small things that people can do that can make a serious impact on the final outcome. If fact doing these things could possibly prevent it.  The suble fact is that if it is prevented it will be very hard to tell whether what we did was necessary.  Very small reductions in how infectious people are and how many people they come into contact with can have a dramtic effect.  For a non-technical overview of the mathematics of epidemics and disease, there is an excellent article in the online maths magazine Plus.

So in conclusion, spread the flucode and think about things don’t just consume the story you like!


Unscheduled Post: The British Police

April 21, 2009

My apologies for a slightly off-topic post.

I am an educated middle class white boy, with a fairly posh accent. I am sure that this has nothing to do with the fact that my interactions with the Police in Britain have always been professional and courteous. As a result I have always had a great deal of respect for them.  One particular incident that stands out in my mind was at New Year. I had been in central London, which was packed with people. As I did not fancy taking the tube, I decided to walk.  To do this I needed to cross the river. So did a lot of other people. Several bridges, however, were shut. This was irritating. Yet, even after a long night there was a senior officer on one of the bridges dealing with people’s aggression and patiently explaining why the bridges were shut, and exactly what he knew about when they would open. I finished my walk proud of my country.

This is why it makes my heart bleed to see what is happening around the recent protests in London. Even before things started the police were constantly talking up the risk of violence. Their tactics on the day, such as baton charges and kettling seem designed to fulfill their own predictions. Worse yet even after the public relations disaster made worse by the failure to be open about the shooting of Jean Charles de Menezes, the initial response was to cover their actions up.  In doing so they managed to outrage even papers like The Telegraph. In addition to the PR trouble shooting there are more sinister attempts to aid this, such as the ban on “little brother”  taking pictures of the police. Again, even The Telegraph thinks this is a little over the top.

The biggest tragedy (unless you are a member of the Tomlinson family) is that the news surrounding the events has been taken up with the police response. This helps prevent an open and inclusive debate about how society could be run and how it can move on from the current crisis.


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.


Carnival of Mathematics #44

November 21, 2008

44 is currently a very relevant number, as the historic 44th president will be inaugurted next year. Finally it is a tribonacci number in the sequence 1,1,2,4,7,13,24,44,… where the three previous numbers are summed to give the next.  These are of course linked to the polynomial x^3-x^2-x-1 = 0, but also to the beautiful Rauzy Fractal (shown as an approximation):

The Rauzy fractal, the three shapes are similar and together they build the next size up.

 

Now to the posts, and we begin with a news segment.  In Britain the two major mathematics societies, the LMS (London Mathematical Society) and the IMA (Institute for Mathematics and it Applications) are talking about merging.  There has been some debate over this as the two societies have different goals.  The opposition have started a blog on the subject, you can read the case is support here.  More controversy was generated over the strange publications in Chaos, Solitons & Fractals, a refereed Elsevier journal.  Various blogs covered this, but the main story, along with an amusing debate appeared in the n-category cafe.  On a more positive note we had the sesquicentennial of the Möbius strip.  (does anyone outside mathematics use the term sesqui for one and a half?)

Having warmed up we move on to some more serious maths, of different levels.  We start with an example of how knowing maths can help perpetrate reduce fraud, with an explanation of the Luhn checksum algorithm.  We also have the observation from reasonable deviations that a class of 2×2 matrices are isomorphic to the complex numbers.  You can learn how to bound binomial coefficients at the Endeavour, or generate Pythagorean triples at 360.  To stretch your mathematical muscles a little more look for Terry Tao, considering polynomials on finite fields ranging over a finite group.  Technical but interesting.

If you are interested in the culture of maths, you can sample from the ancient to the modern. The mathfactor podcast discusses the Ishango Bone, our earliest record of mathematical thinking from 20,000 years ago, and Curving Normality considers how immigrant children fare in the maths education system.

That’s the hard work out of the way, so its time for some mathfun.   Returning to 360, you can consider a geometric excuse for an addictive game.  Gil Kalai presents a couple of very high quality puzzles, with an elegant solution that is easy to explain, but hard to find.  Another interesting puzzle from Jason Dyer, can be turned into a magic trick, or maybe that should be turned back into a magic trick.  Less thought is required to enjoy Mike Hubin’s Tolkien spoof.

If this list has not given you enough of that math fun, and you want links outside the blogging world Larry Ferlazzo has lists of maths websites and glossaries

To conclude as I began with numbers meaning something other than mathematics, A million good things has a very ambitious project of posting 1,000,000 good things, one every half hour for most of the rest of his life.  He is starting next year and so far only has 30, (15 hours worth) worth lined up.  Lets make sure the list contains lots of good maths!
