The UK government is encouraging people to take regular COVID tests even if they show no symptoms. Schoolchildren are already testing themselves twice a week, and it is hoped that regular testing will help to prevent asymptomatic carriers from spreading the disease.

However, some people are concerned there will be too many false positives: people whose test gives a positive result, forcing them to self-isolate even though they do not, in fact, have COVID. …

“A wise old ruler wanted to reward his servant for an act of extraordinary bravery. The servant said:

‘Master I ask you for just one thing. Take your chessboard and place on the first square one grain of rice. On the first day I will take this grain home to feed my family.

The premise of this week’s blog was simple: see how Liverpool’s Premier League title defence compares to other unsuccessful defences over the 28 years of the league’s existence.

Over the past two months, I have visited some websites that estimate when I can expect to be offered a vaccine; however, as the program appears to be exceeding expectations, the dates are moving (earlier!), and in any case it’s not obvious what assumptions are being used.

Therefore I thought it would be fun to use Python to produce a few graphs tracking the programme and predicting what might happen next.

The UK government website has…

Over the last few years, I have been increasingly interested in how we can get people coding. I don’t mean advanced coding as a discipline in itself, but using coding to help in everyday life, in the same way as we would use a word-processor or a calculator.

One of the difficulties has always been the high ‘barrier to entry’ of installing the correct software and learning the basics, which must be done before the beginner can see how coding can be used in interesting ways.

Whilst testing Filament, Euan Wielewski and I have seen how easy the platform makes…
