Paul the Octopus: soon to hit the silver screen

Just up on Youtube is the trailer for the forthcoming feature film about Paul the 'Psychic' Octopus (RIP): not only does it feature DJS explaining the mathematics of Paul, but it includes Bayes theorem. And it is in Tentacular 2D!

Time to cut down on the booze?

The recent study on alcohol and cancer published in the British Medical Journal is a fine piece of epidemiology and attracted a lot of coverage of the estimate that 10% of male cancers and 3% of female cancers could be attributed to alcohol.

Another priceless infographic from the Times ...

After their previous attempt at a Nightingale rose, here is another ghastly example from today's edition of the Times. Shouldn't someone tell them?


Perhaps Japan's acceptance rate looks more than twice the size of China's

Professeur Poisson still rules

We've previously shown that the number of homicides each day in London followed a Poisson distribution to a remarkable degree - this means that they essentially occur as a random process. Now the same analysis has been repeated by the Home Office in the crime statistics released today - and the Poisson fits very well.
