Averting Castrophe Georgia State mathematician Igor Belykh has spent more than a decade studying how bridges become unstable now he’s devising ways to improve their safety.

Bridges are like birds — they live on the earth and in the sky. They allow us to cross what is not crossable. They seem to defy gravity, suspended over water, gorges and ravines; and yet they can be dangerous, even deadly, when they become unstable or collapse.
