A special anniversary theme

For its 30th anniversary, the Science Fair has decided to invite all those who have been committed to sharing knowledge for the past three decades to share the emotion of discovery and the iconic expression “Eureka!”. The perfect opportunity for researchers to share their work with the public; from their daily activities and scientific process to their struggles, challenges and, of course, their “Eureka” moments. What about you – how do you feel when you “discover” something new?
