Without a Doubt?
Until 29 August 2027 from 10:00 to 17:00
Exhibition
How exactly does science work? Find out for yourself in the exhibition Without a Doubt?.
Truth
It was once believed that black swans did not exist. Just like purple cows and flying pigs, the black swan symbolised the impossible: swans were only white. Full stop. Until, in the 17th century, black swans were suddenly spotted in Australia. Scientists had to revise their theory, which they had regarded as the absolute truth for centuries, at a stroke.
Basic Principles
It just goes to show: science is not absolute truth. But neither is it merely an opinion. It is the best way we have of acquiring reliable knowledge. In this interactive, contemporary exhibition, you’ll discover exactly how that works. Five basic principles are highlighted that form the foundation of scientific research: Evidence, Repetition, Revision, Testing and Building on Previous Work.
