The engineers in the manufacturing, particularly among the Small and Medium Enterprises, are often thinking that the University Laboratories are too far from them: it is true that the engineers have to solve many urgent day per day problems and that they need to fight to survive among all their competitors, meanwhile the professors-researchers have in principle time to think, to define alone their actual domains, sometimes at a very fundamental and unclear level, and to “try to solve” them. The purpose of the lecture will be to show a scheme of the actual situation in France based on the experience of one researcher in mechanics and his real implication/dedication to manufacturing.
