News of some significance

You may have heard of the replicability crisis in science, and practices like outcome switching and p-hacking. BuzzFeed reports on a paper that proposes a solution: rather than assign statistical significance at $p=0.05$, change this value to $0.005$.

Sir David Spiegelhalter is quoted saying: “Dealing with the size of the p-value fixes some things. But it’s not dealing with the most important issues.” There’s a lot more in the BuzzFeed article and the full paper.

Particularly mathematical Birthday Honours 2014

With the announcement the Queen’s Birthday Honours list, it’s time for the latest in our ongoing Honours-watch series of posts. In this, we search arbitrarily for ‘mathematics’ in the PDFs of the various lists, and hope our well-informed readers fill in the blanks where actual knowledge is required.

Maths at the Cheltenham Science Festival

Next week, scientists, science fans and science communicators will converge on Cheltenham town hall for a week of high-quality science festival. But how much of the programme is given over to the queen of all sciences, Mathematics? Here’s a list of some of the events going on we’d be interested in going to.

Follow Friday, 9/11/12

At what can only be described as far too regular an interval for such things, it’s another Follow Friday! Here’s who you should be getting in line behind people to follow this week, as well as some of their recent interesting links.

L’Aquila seismologists found guilty of manslaughter connected to earthquake risk assessment

In David Spiegelhalter’s excellent programme on risk, Tails You Win: The Science of Chance, we heard about the classic case of Michael Fish failing to predict the 1987 hurricane, and about the difficulty of predicting such events. Another area where precise prediction is extremely difficult is earthquakes.

Today the BBC are reporting that “six Italian scientists and an ex-government official have been sentenced to six years in prison” in L’Aquila, Italy, having been found “guilty of multiple manslaughter” because of a “falsely reassuring statement” they gave before a 6.3 magnitude earthquake struck the city in 2009 and killed 309 people.

Probabilitelly

Prof David Spiegelhalter always rolls spider-eyes

On the 18th of October BBC Four is going to broadcast a programme called Tails You Win: The Science of Chance, presented by Prof David Spiegelhalter, as part of its Big Science series.

Here’s the BBC’s description:

Smart and witty, jam-packed with augmented-reality graphics and fascinating history, this film, presented by Professor David Spiegelhalter, tries to pin down what chance is and how it works in the real world. For once this really is ‘risky’ television1.

The film follows in the footsteps of The Joy of Stats, which won the prestigious Grierson Award for Best Science/Natural History programme of 2011. Now the same blend of wit and wisdom, animation, graphics and gleeful nerdery is applied to the joys of chance and the mysteries of probability, the vital branch of mathematics that gives us a handle on what might happen in the future. Professor Spiegelhalter is ideally suited to that task, being Winton Professor of the Public Understanding of Risk at Cambridge University, as well as being a recent Winter Wipeout contestant on BBC TV.
