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.


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.


WoW 4: Fractals

April 16, 2009

I am often a bit rude about fractal art.  With the right software it becomes easy to create interesting, attractive, complicated images without much thought to what is happening.  It is unfair but I find myself turning away from all of the work, because some of it might perhaps lack rigour.  Just as you might give up on conceptual art after seeing one unmade bed too many.

To redress this balance the winners this week (again its several winners, first to claim gets the prize!) are a couple of sites from artists who clearly engage in the mathematics, creating new objects.  They also have draw dropping rendering skills, that I am very jealous of.

I am going to let the images speak for themselves.  You really should click through for much more goodies.

Maxwell Demon: Website of the week

I am handing out awards, the imaginatively titled “Maxwell’s Demon” website of the week:

wowThere is even a prize, £50.  Though I am lazy so the conditions of this are that the winner:

1) Realises they have won.

2) Contacts me.

3) Puts the logo on their site.

Of course 3 is hard to enforce so you could probably take the money and remove the graphical mess.  I will therefore claim that 3 is to ensure that you are indeed the winner.


Unscheduled Post: Hyperbolic Polydron

April 13, 2009

What happens when you put seven equilateral triangles round a point?  

Inspired by sumidiot who was himself inspired by division by zero who were making paper hyperbolic soccer balls, I thought I would put up some pictures of a similar project with polydron.  The construction is simple.  Attach seven triangles round a vertex this gives 7 outside vertices.  Add triangles so these all have exactly seven around them and repeat.  The surface flexes in most interesting ways.

Interestingly it is still an open question whether, assuming zero thickness and perfect hinges, this construction can be continued for ever, embedding a model of the hyperbolic plane in 3 dimensions.  If you take eight triangles round a vertex I believe it is possible as you can regularly fold things up and down.

David Richter has some more thoughts and discussion.
