Thanks to a prize of half the proceeds of a football match, we learn about some numbers that attract the others so that they can't escape from them.

Mathematical sequences which lead to mathematical black holes.

]]> Let's give away some balls. Sat, 6 Apr 2013 00:03:52 +0200 http://www.matifutbol.com/en/balls.html

Close packing. Geometry.

Organizers of Brazil 2014 FIFA World Cup want to give away some official balls.

We face a close-packing problem in order to know if we can fill Maracana stadium with enough balls to satisfy the Championship organizers' wishes.

]]> The problem of the fair division. Fri, 1 Mar 2013 18:08:21 +0100 http://www.matifutbol.com/en/fairdivision.htmlbenefit match.

Eto'o and Drogba have been designated captains of the 2 teams, but they don't know how to split the rest of the players between their teams.

Do you now how can they do so that both players be satisfied?

Do you dare to solve this other problem of lateral thinking?

Mourinho is thinking about how to counter more effectivily the game of F.C. Barcelona midfielders.

That way, thanks to the tactical arrangement of a football team, we study one of the notable points of the triangle lesser known but with many practical applications: the Fermat point.

It's Christmas Day, and it's been held a benefit match for the Misunderstood Mathematicians. A player is sustituted, and the average age of the team rises 2 years. With this data, we work out an interesting reflection on arithmetical means and their variations related to the members of the group.
