A site developed to help non-scientists, or students embarking on a career in science, to understand "the scientific mind-set". Why do we carry out some experiments which, at first sight, seem crazy? For example, why would we make rabbits which glow in the dark? And why don't we give straightforward answers to questions but instead make everything so complicated? This website will help students to understand some of the issues that scientists worry about and consequently "why do scientists do what scientists do."
