Something a bit different today. As part of the research for our book, we created a two-step Markov model to analyse the Queen’s Christmas Messages and generate tweets in the same style. We’ll be tweeting these out from now until she delivers her message (When you can test how accurate we were!).

FOLLOW THE ELIZABOT HERE!

Across her 64 messages (including a written message in 1969), our Liz has actually got through a remarkably wide range of topics (with admirably little repetition, given the unvarying nature of her brief!), so don’t be surprised if the Elizabot comes out with the occasional musing on magnets, bagpipes or football.

In our new book, The Indisputable Existence of Santa Claus, Dr Hannah Fry and I discuss a mathematically superior way to organise your office Secret Santa. However, some people think they have found a flaw in our system…

Never fear though, we have a solution up our sleeves. I just hope you like cutting and sticking…
