The production of contemporary scientific knowledge is changing, it is more influenced by factors and actors outside specific disciplines and more embedded in society; or, at least, many people work to engage new voices in science. Post-academic science is influenced and shaped by several entities; not only scientific but also political, military, industrial and those related to organizations and civil society. Part of the mission of contemporary science museums is to create a free environment and a context for the negotiating, involving policy makers, scientists, civil society and companies. But are museums indeed free spaces for negotiating knowledge? Are museums able to share and negotiate knowledge linked with their programs and messages by creating a shared agenda between all the different actors?
