Tails, Bayes loses (and invents data assimilation in the process)

Trying to make a prediction about the world based on dodgy data? Then data assimilation has the answer!

Maths in a minute: Inverse problemsInverse problems are mathematical detective problems. They can help solve crimes, are used in medical imaging, and much more.
The shower equation: Dealing with delayMany processes, including climate change and the spread of COVID-19, involve a delay. Here's a beautiful equation designed to model such processes.
Myths of maths: The Monty Hall problemThis puzzle is famous because the accepted answer is counter-intuitive. But is it always correct?
Myths of maths: The four colour theoremIt's one of mathematics' most famous results: every "map" can be coloured using at most four colours. What it doesn't usually apply to, however, are real maps.
Myths of maths: The golden ratioThe golden ratio has many amazing properties. But is it really a secret of nature and the epitome of beauty?
Elections: Could they be fairer?With a bit of maths, yes!
