Photo by  Etienne Jong  on  Unsplash The BBC has just spent a week attempting to encourage a more green way of life - a worthwhile aim, even if it often resulted in distinctly uninspiring advice such as 'Use a reusable coffee cup.' However, on a couple of programmes I heard a suggestion that struck me as simultaneously both sensible and stupid in its limitations. We were told to reduce shorthaul flights. I think the logic behind this is that it's easy to use a more environmentally friendly option like rail for relatively short journeys. And I certainly would both advise people to consider taking the trains and ask governments if they couldn't do something about the ridiculous situation that it's often much cheaper to fly than travel by rail. However, the flying elephant in the room (is that a mixed metaphor, or just Dumbo?) is that longhaul flights have a far bigger negative environmental impact than shorthaul. So why weren't we told to reduce them as well? I s...

Image by Mateo Abrahan from Unsplash Listening to podcasts has transformed walking for exercise - and has been a revelation after the rigidity of traditional radio show formatting that requires a programme to be, say, 30 minutes long, no more, no less. However, a couple of podcasts I listened to this morning have demonstrated how things can go wrong at the boundaries. The (2022) podcasts in question were the 14 May episode of More or Less: Behind the Stats , lasting 9 minutes, and the 6 May episode of Kermode & Mayo's Take , which runs to 1 hour 59 minutes. These are clearly extremes - I think it's fair to say that most podcasts are in the 30-50 minutes range. But each illustrates a point. Let's take Tim Harford's More or Less first. This one demonstrates the danger of making a podcast that is just a radio programme repackaged. It is part of a series that is broadcast weekly on the BBC's World Service and has a rigid 9 minute slot. If it had been a real podcast...

This is an update of a post from 2013, which still seems very relevant today:  I was watching the BBC school soap  Waterloo Road*  the other day, and ended up rolling all over the floor moaning. Because we saw a 'science teacher' making one of the most basic possible errors. Would they have allowed an English teacher to write on a board that Hamlet was written by T. S. Eliot? Or a geography teacher to note down the capital of France as Belgium? I would hope not. Yet this is a comparable error. Take a look at this little snap. What is she doing? It seems she has invented a new kind of hydrogen peroxide that is made up of H-squared and O-squared. I have no idea what a squared atom is, and I wait with interest to see the BBC's drama department explaining all about these new particles. At the very least, I would expect a squared atom would enable us to perform cold fusion. In the meanwhile I just don't understand what kind of editing process at the BBC can allow H 2 O 2 ...

Scott Hershovitz is a little harsh in applying Hobbes’ aphorism calling human life ‘nasty, brutish and short’  to children, but his idea of using children’s musings as a starting point for exploring some of the big philosophical ideas with an adult audience is little short of genius. Hershovitz points out that until about the age of nine, children are naturally philosophically minded, as demonstrated by their perpetual asking of the question ‘Why?’ Science communicators find a similar effect with science - pretty well all children are fascinated by science until they are 11 or 12 (I’m sure there’s a research paper in there for why one interest dies before the other). Not only does Hershovitz encourage this exercise in thinking by turning the questions back on his children, but he also stimulates readers to think about these issues themselves. As he points out, you might not always agree with him (I certainly didn’t), but it’s a valuable exercise to think through these big idea...
