"Go to temples of science and ideas of Europe. Imitate the Tugendbund, 'the Union of Virtue', of which thousands of German youth are the members. Always keep the rule of 'Fit soul is in fit body' in mind" (Petrov, 2013, p. 72). This study aimed to show the similarities, in terms of expression, emphasis, and implication, in the about/mission/vision/goals/objectives of various science centers from around the world and in the basic themes derived from Snellman's statement above, namely, Science for all, Science Centers for all, and Human welfare that he made as a challenge to not only his people but to everyone. Document and content analyses were applied in the study. Within the scope of these analyses, this study investigated the about/mission/vision/goals/objectives sections of websites of science centers from around the world (Asia, Europe, Global, Latin America/The Caribbean, North America, Africa). From this investigation, similar basic themes, derived from Snellman's statement challenging his people/everyone to adopt this devotion to science, were found in the areas of i) expression in ASTC, CIMUSET/CSTM, CASC and SAASTEC; ii) emphasis in ECSITE, ASDC, ASCN and NSCF; and iii) implication in ASPAC, ASTEN, NCSM, ABCMC and Red-POP. These basic themes, as found in the about/mission/vision/goals/objectives of science centers, can, in effect, be narrowed down to the one theme of "cultural institutions will be a big part of human life" (Madsen 2017, p. 68) science centers in the global village (Touraine, 2016, p. 121) of the future.
