The idea that math doesn't just have to be practical, but that you can also do math just because it is fun, is nearly 4000 years old and was first thought up by the Babylonians. In order to keep this ancient tradition of doing recreational maths alive, the Cie Infinity organises the Recreational Math Evening every month. An evening of looking at fun mathematical questions together, of the type that you also get at contests like the (international) math olympiad, the MOAWOA or the IMC. Everyone is welcome and there are exercises of every level! So join the dork side, we have cookies!
