(Click image for full view.) A French helmet from World War I sits beneath a shock tube to test how well it protects the dummy underneath from a shock wave. The ridge down the center of the helmet was designed for deflecting shrapnel, but may well have also helped deflect the shock wave, allowing the helmet t...

For the first time, academics developed a systematic literature review of the causes and cures of poor megaproject performance. They identified six key themes and looked at areas where a project might fail, analyzing the problems and solutions.
Academics at University College London have identified 18 reasons...
