In a world longing for certainty and clear-cut answers, the Museum of Doubt makes a powerful case for doubt, vulnerability, and complexity as driving forces of both science and citizenship. Professor Marjan Doom, director of the Ghent University Museum (GUM) & its neighbouring botanical garden, invites readers to reflect on the role of science museums today. Drawing on personal experience and curatorial case studies, she reveals how art and science enrich one another, how doubt is not a weakness but a necessity, and how museums can bridge the gap between science and society. A sharp and compelling ode to critical thinking.
