Mensa was founded in England in 1946 by Roland Berrill, a barrister, and Dr. Lance Ware, a scientist and lawyer. They had the idea of forming a society for bright people, the only qualification for membership of which should be a relatively high IQ. The original aims were, as they are today, to create a society that is non-political and free from all racial or religious distinctions.
The word "Mensa" means "table" in Latin. Mensa is a round-table society, where sex, age, race, color, creed, national origin, age, politics, educational or social background are not valued as entry criteria. The society welcomes people from almost every walk of life whose IQ ranges in the top 2% of the population, with the objective of enriching each other's company and participating in a wide range of social and cultural activities.

Contest April 2012

The April contest has ended.

The Easter Bunny rides his bicycle along the railroad from Ostermundigen to Hasliberg. Every 30 minutes a train comes towards him from the opposite direction. Every 45 minutes a train passes him from behind. But actually the trains go at the same frequency in both directions. 

What is the real time difference in minutes between two trains?

From those who sent us correct solutions by April 30th, we will draw two winners and send them a voucher for our test.


Contest February 2012: Euclid's Cake

The February contest has ended.

At a children's birthday party, Euclid serves a circular cake and asks the children to cut the cake into a finite number of equal and continuous pieces. The only condition he insists on is that at least one piece must not touch the center point.

So the usual way of cutting a cake into pieces, as shown in the figure to the right, is not allowed, as all of the pieces touch the center here.

Equal means that all of the pieces must have the same shape and size. Reflections are allowed.

Contest December 2011: Game Show

Der Dezember-Wettbewerb ist beendet.

Hinter drei Toren sind versteckt: ein Auto, eine Ziege und ein (zum Auto passender) Zündschlüssel.
Ein Team von zwei Spielern möchte zusammen das Auto gewinnen.

Die Aufgabe des ersten Spielers ist es, den Zündschlüssel finden. Er darf dazu nacheinander zwei Tore öffnen. (Für diejenigen, denen das Problem irgendwie bekannt vorkommt: Nein, diesmal gibt es keinen Moderator, der einen fragt, ob man seine Meinung ändern will. Das war ein anderes Problem.) Das erste gewählte Tor wird sofort geöffnet. Ist der Schlüssel dahinter, ist es gut, ansonsten hat der Spieler noch einen zweiten Versuch.
