A science book like no other

 I've had a bit of a flurry of publication, mostly due to dates shifting thanks to Covid, resulting in three books being published in September. Two of these were Ten Days in Physics that Shook the World and Ten Patterns that Explain the Universe (in an attempt to corner the market in books with 'ten' in the title), but the most unusual one by far was How it All Works , written with Adam Dant. In fact, 'written with Adam Dant' is a huge understatement - this is very much Adam's book. He is a remarkable artist who produces wonderfully detailed crowd scene drawings. All I did was suggest some scientific principles and phenomena to go in the illustrations, and added a few words on each. The result is a sort of cross between Where's Wally and a popular science book. You really don't have to care much about the science to enjoy the remarkable illustrations.  Rather than do what appears to be blowing my own trumpet (though my enthusiasm is all for the drawin

Percentage of what?

Every now and then a use of numbers pops up on the news that mildly irritates me. One of the worst thing the news media often do is to use a percentage without giving absolute figures to put that percentage into context. For example, imagine that we hear that the murder rate in a city has gone up by 100% compared with last year. Shock, horror, sack the police. But if it happens that the murder rate last year was 1 victim, that 100% increase is 1 extra person. Not exactly a massive change and highly unlikely to have any statistical significance. The latest version of this problem has been repeated over and over. We are told that unless the triple lock on pensions is suspended, the state pension in the UK could go up by 8% next year. A vast increase. But again, without the context it's impossible to tell what 8% means. As it happens the UK has an unusually low state pension for a European country. There current maximum is £718.40 (confusingly, this is over four weeks but isn't th
