Dmitry Khavinson and Genevra Neumann didn't know anything about astrophysics. They were just doing mathematics, like they always do, following their curiosity. In 2004, they posted a new result, an extension of the fundamental theorem of algebra, on MathSciNet, a preprint server.
Five days later, they received an e-mail. Congratulations, it said. You just proved Sun Hong Rhie's conjecture on gravitational lensing.
Gravitational what? Khavinson, of the University of South Florida in Tampa, and Neumann, of the University of Northern Iowa in Cedar Falls, had never heard of it. So they started a crash course in gravitational lensing.

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
