    What can modern engineering learn from an erstwhile jeweler who built the largest masonry dome in existence? The construction of the Florentine duomo by Filippo Brunelleschi has been an engineering marvel for more than 500 years, showcasing ancient techniques that still hold valuable insights for modern engineering. Until now, it has remained a mystery how the master goldsmith and sculptor managed to build the masterpiece that pushes the limits of what is possible to construct even with modern building technologies, and how the masters who followed Brunelleschi carried on the tradition.

    Belying their slimy natures, the sticky patches of bacteria called biofilms often form intricate, starburst-like patterns as they grow. Now, researchers at Princeton University have combined expertise in molecular biology, mechanical engineering and mathematical modeling to unravel the physical processes underlying these curious crinkles.

  • New mathematical model can more effectively track epidemics

    As COVID-19 spreads worldwide, leaders are relying on mathematical models to make public health and economic decisions.

    A new model developed by Princeton and Carnegie Mellon researchers improves tracking of epidemics by accounting for mutations in diseases. Now, the researchers are working to apply their model to allow leaders to evaluate the effects of countermeasures to epidemics before they deploy them.
