For the first time a TEDx event was hosted in Louvain-la-Neuve last 23 march 2013. It was the 4th anniversary of TEDx and plenty of conferences were organized around the world at this occasion. Like all TED conferences, the spirit of this conference was based on the motto “ideas worth spreading”. Sixteen speakers were invited to give twenty minutes talks on various subjects going from artistic cooking, to collective awareness over politics and bad managements practices in companies. The day was divided in four parts of four talks and between the parts we had the opportunity to discuss with the speakers and the audience on an informal way.
