About World Science Day for Peace and Development

Science communication works best when it explains evidence, uncertainty, methods and limits rather than presenting scientific knowledge as a list of unquestionable slogans.
The observance is also an opportunity to discuss who can participate in science, who benefits from research and how scientific cooperation can support peaceful and sustainable societies.
