Scientific revolutions in a nutshell
The scientific community cannot practise science without some set of accepted beliefs that form the foundation on how to practice science.
Normal science, the everyday work of scientists, is set on the assumption that the scientific community knows what the world is like. Its success comes from the community’s willingness to defend that assumption. But when it can no longer escape anomalies that overturn the tradition of scientific practice, then a scientific revolution will at last lead to a new set of commitments.
