AWWTM: Risk compensation and bicycle helmets

Some months ago I left a series on bicycle helmets hanging while I got distracted with other things. We had looked at what the best evidence for the efficacy of helmets in preventing injury in the event of a crash is, and some of the reasons why we should be […]


AWWTM: Setting ourselves up for economic collapse

In January last year, while shadow chancellor, George Osborne said that the lesson of the credit crunch is that “the economy must never again be allowed to become so structurally unbalanced and poorly prepared for a downturn.” He was referring to our national over-reliance on the banking sector, which had made […]


AWWTM: Friday photo: modern mail

This is the view from my office kitchen back when I had that real job (before I gave it all up to do this instead).  The sun is rising over the city, with the Docklands towers just visible, pale in the distance between the Barbican towers. The street in the […]


AWWTM: Can drivers be taught a lesson?

M’coblogger Ed thinks there is a case for teaching drivers to behave — specifically by appeals to patriotism. Education programmes are a popular idea amongst cyclists, cash-strapped councils, and road safety types. I dismissed them as a solution that doesn’t work in my own post on revenge and road danger, […]


AWWTM: Three* stone circles that are way better than Stonehenge

Model splicing

This is another archival repost, written for the old blog in January 2008. The central dogma of molecular biology, first described by Francis Crick in 1958, describes the flow of information between DNA, RNA, and proteins.[1] The central dogma is interesting, but I believe that its use in teaching is […]


AWWTM: Friday photo: a handsome Raleigh tourer

On the urban motorway that is Whitechapel.  Whitechapel should be the quintessential neighbourhood High Street: it has the tube station, the bus stops, the shops and pubs and library — sorry, “Idea Store” — and the street market that these vans supply.  As Andy Cameron would put it, Whitechapel has […]


AWWTM: This pretense of neutrality

On Saturday I wrote about the leaked draft of the Tories’ coalition’s draft new planning policy document: LAs are told to take into account existing local car ownership rates when doing this.  Fair enough, but why aren’t they also told to take into account the elasticity of modal share in […]
