What is the roundest country?
Gonzalo Ciruelos
Summary
The article [b]“What is the roundest country?” explores how mathematical ideas can be used to measure the shape of countries. Since real borders are irregular, the author defines roundness using a geometric formula that compares how much a country’s shape overlaps with the best-fitting circle. A perfect circle would have a roundness value of 1, while less circular shapes score lower. [/b]
Using this method, the article calculates and ranks countries by their geometric similarity to circles, finding that Sierra Leone is among the roundest with a score of about 0.934. The work shows how mathematics, geometry, and computer analysis can reveal unexpected properties of familiar geographic shapes.
