Title:
The geometry of soccer balls
Speaker:
Abstract:
Have you ever looked carefully at soccer balls? Did you notice that they are usually made of 20 hexagons and 12 pentagons? Why is it so ? Did you notice that the official ball of the 2014 World Cup in Brazil, nicknamed Brazuca, looks very different? I will describe the underlying geometry of these popular sporting balls, plus others, utilizing recent mathematical results.
