"The 2011 Researchers' Night coordinated by the Silesian University of Technology (Gliwice, Poland) is actually continuation of 5 previous similar events. For the past 3 years we have cooperated with other Silesian Universities acting under the name 'Silesian Researchers' Night'. This year in frames of the Silesian Universities Network we managed to build a partnership of 5 Silesian universities taking part in the 2011 event. We aim in future at building a consortium gathering all Silesian universities, which will increase the effectiveness of the communication activities organised in the area counting almost 4,9 million inhabitants.The broad and varied programme of activities will address all categories of public, regardless of age and scientific background, and combine in balanced way serious and fun activities. They will take place at the university campuses (in Gliwice, Katowice, Bielsko - Biala Rybnik and Sosnowiec) situated in the city centres. The activities will notably include: face to face meetings with researchers, experiments conducting by the researchers and the audience (supervised by researchers), workshops, live-demonstrations, lectures, concerts, shows, contest, researchers talking about their passions. In order to allow young participants to enjoy the activities they will start early in the afternoon and last late into the night. As in previous years we plan to engage the whole school groups and families in all the activities taking part in our region.Main goals of th event are: enhancing public recognition of researchers ant their work, attracting as many people as possible to the event, rebuting the stereotype of a scientist as a strange, cold person closed in the four walls of their laboratories, showing that everyone can be a scientist and encouraging young people to choose a scientific career path, stopping the outflow of young scientists from Europe to the USA, showing that European science has a lot to offer (FP7, Marie Curie Actions)."
