Transdisciplinarity is a new scientific, cultural, social and spiritual approach. As the prefix "trans" indicates, it is concerned with what is at the same time "between" disciplines, "across" disciplines and "beyond" any discipline. Its aim is the full understanding of the present world, for which one of the imperatives is the unity of knowledge. It can be defined as the recognition of the interdependence between all aspects in reality. The academic world, the world of sciences is currently the world of autonomous and isolated disciplines. However, due to its dizzying progress and the proliferation of corresponding technologies, the complexity of problems is leading to the approximation and reconstruction of the association between disciplines in different degrees, from the simplest (monodisciplinarity) to the most complex (transdisciplinarity). In other words, it is an integrating tendency, capable of creating bridges between disciplines, a common ground for dialogue, exchange and interconnection. The word transdisciplinarity was first used by Piaget in 1970.
