Musical Education

9 November 2014

On our longer family drives I take an old iPod crammed with even older music. Usually I take requests, and almost inevitably the children choose They Might Be Giants, and preferably the tracks Fingertips and Particle Man. But, our last trip was different. Instead I took the opportunity to the children some exposure to artists formative in the history […]

Sleeping Beauty – a “halfer” approach

29 September 2014

If you read the last post on the Sleeping Beauty problem, you may recall I did not pledge allegiance to either the “halfer” or the “thirder” camp, because I was still thinking my position through. More than a month later, I still can’t say I am satisfied. Mathematically, the thirder position seems to be the […]

Sleeping Beauty

26 August 2014

For the last couple of weeks, I have fallen asleep thinking about Sleeping Beauty. Not the heroine of the Charles Perrault fairy tale, or her Disney descendant, but the subject of a thought experiment first described in print by philosopher Adam Elga as follows: Some researchers are going to put you to sleep. During the two days […]

Government spending

20 May 2014

Before, during and after this month’s budget, Treasurer Joe Hockey sounded dire warnings about Australia’s “budget emergency”. Amidst this fear-mongering, it was a pleasant relief to come across a dissenting view. In a recent interview on 2SER Dr Stephanie Kelton (Department of Economics at the University of Missouri in Kansas City) argued that the government budget is very […]

Randomness revisited (mathsy)

21 April 2014

My recent randomness post hinged on people’s expectations of how long a run of heads or tails you can expect to see in a series of coin tosses. In the post, I suggested that people tend to underestimate the length of runs, but what does the fox maths say? The exploration of the numbers in this post draws on […]

Do Daleks use toilet paper?

18 April 2014

I have been watching some (very) old Doctor Who episodes, including the first ever serial featuring the archetypal villains, the Daleks. In this story, the Daleks share a planet with their long-time enemies, the Thal. After a war culminating in the denotation of a neutron bomb, both races experience very different mutations. The Daleks have […]

Randomness

6 April 2014

With three children, I have my own laboratory at home for performing psychological experiments. Before anyone calls social services, there is an ethical committee standing by (their mother). This evening, I tried out one of my favourites: testing the perception of randomness. Here is the setup: I gave the boys two pieces of paper and […]

Chinese non-residents…in China

31 March 2014

Recently I travelled to China for the first time. My first glimpse of Beijing took in the Escher-like headquarters of Chinese TV station CCTV. It is an extraordinary building and to get a proper sense of it, you have to see it from a number of different angles. Driving across the city, impressed by the […]

I’m with Felix

16 February 2014

FT blogger Felix Salmon and venture capitalist Ben Horowitz have very different views of the future of Bitcoin. Salmon is a skeptic, while Horowitz is a believer. A couple of weeks ago on Planet Money they agreed to test their differences with a wager. Rather than a simple bet on the value of Bitcoin, the bet centres […]

Shark season

31 December 2013

Summer in Australia comes with cicadas, sunburn and, in the media at least, sharks. So far, I have learned that aerial shark patrols are inefficient (or perhaps not) and that the Western Australian government plans to keep swimmers safe by shooting big sharks. Sharks are compelling objects of fear, right up there with spiders and snakes […]
