Here's a simple game at which a human can out-fox even the cleverest algorithm.

The INI is celebrating its 30th birthday. What is it and what is it do for maths and mathematicians?

Here's our coverage from the International Congress of Mathematicians 2022, including the Fields Medals and other prizes.

The COVID-19 pandemic has amplified the differences between us. Understanding these inequalities is crucial for this and future pandemics.

There have been accusations that the modelling projecting the course of the pandemic was too pessimistic. Are they justified?

Got a 4x4 area, your arrangement fits 9, while triangles fit 8. Got an 8x8 area, squares fits 25, triangles fits 24. Got 12x12? squares 49, triangles 50. 16x16? squares 81, triangles 91 (I think).

Each time you add more people past 9 or 8, you have to position them far enough away from everybody else. As the number of people increases, triangles take less area to achieve adequate distance for each person.
