Equidistance is introduced very early in geometry. Perpendicular and angle bisectors are the simplest examples. Let us go further and consider points equidistant from a line and a circle, from two circles, or even from two more general curves. How far can we take this?

Practising the Japanese abacus is considered an art in Japan, where, as in judo, practitioners progress through kyu belt ranks and then dan grades.

It is easy to overlook, but many geometric problems can be solved by iterative methods or, more broadly, algorithms. These questions are the subject of computational geometry! This is a vibrant, highly active field in which many seemingly elementary questions still await solutions.

A highly debatable approach to Persian pentagonal patterns has been repeated so indiscriminately in scientific journals that it has become received wisdom. It is high time to offer another perspective.
