The fracture of brittle amorphous materials is an especially challenging problem,because the way a large object shatters is intimately tied to details of cohesionat microscopic scales. This subject has been plagued by conceptual puzzles, andto make matters worse, experiments seemed to contradict the most firmly establishedtheories. In this review, we will show that the theory and experiments fitwithin a coherent picture where dynamic instabilities of a crack tip play a crucialrole. To...
