The ATCS is a non-gov­ern­men­tal and non-prof­it orga­ni­za­tion with a more than 70-year-long tra­di­tion of work­ing with the young adult pop­u­la­tion in the fields of sci­ence and tech­nol­o­gy. The ATCS’s mis­sion is to pop­u­lar­ize tech­nol­o­gy and sci­ence, edu­cate and encour­age inno­va­tion, cre­ativ­i­ty, and research (among young peo­ple in par­tic­u­lar); to raise aware­ness of the safe, eco­nom­i­cal and effec­tive use of ener­gy; and to encour­age the search for alter­na­tive resources, the care for the envi­ron­ment, and the search for and use of con­tem­po­rary peo­ple- and nature-friend­ly tech­no­log­i­cal solu­tions. The ATCS’s team is expe­ri­enced in address­ing and encour­ag­ing young peo­ple to engage in var­i­ous activ­i­ties and pro­vide their inno­v­a­tive pro­pos­als of solu­tions to var­i­ous prob­lems in soci­ety. The ATCS is accept­ed as the main orga­ni­za­tion that cov­ers the field of sci­ence and tech­nol­o­gy in Slove­nia. The orga­ni­za­tion coop­er­ates with many asso­ci­a­tions in var­i­ous spe­cial­ized fields, as well with all four Sloven­ian uni­ver­si­ties (Uni­ver­si­ty of Ljubl­jana, Uni­ver­si­ty of Mari­bor, Uni­ver­si­ty of Nova Gor­i­ca, and Uni­ver­si­ty of Pri­mors­ka). Every year, the ATCS activ­i­ties attract more than 60,000 chil­dren and young peo­ple, as well as 5,000 sci­en­tists, teach­ers, tutors, and oth­er experts.
