The Association of German Engineers (VDI) with almost 150,000 members, of whom more than a third are students and engineers younger than 33 years of age, is one of the biggest technical- scientific associations in Europe. VDI has extended its activities successfully both nationally and internationally over the years and it has been making great efforts to spread knowledge in the areas related to technologies. As a financially independent, politically unclassified and non-profit organization, it is respected by engineers as well as by professionals and the general public.
