## Note on infinity

A common caricature of the view of the mediaeval scholastics is that they wondered whether the number of angels who can dance on the head of a pin is infinite or not. In fact, this calumny was invented much later. … Continue reading

## Bayes again

It is always a pleasure to read David Colquhoun’s posts. The most recent explains a simple statistical point that still escapes many health adminisitrators (and others). He describes two tests for Alzheimer’s disease. The first (which I will discuss) is … Continue reading
