bridges have grown longer, technically more sophisticated, and much more awe-inspiring, slowly evolving from simple stone arches to gracefully swooping suspension bridges several miles long. Buffeted by winds from above, scoured by rivers from below, pounded by traffic...
Schafer said in the late 1800s, the Quebec Bridge, which had a similar design to Baltimore's Key Bridge, collapsed, which taught engineers many lessons about truss bridges. But by the 1970s when the Key Bridge was built, the design used was modern and sufficient. S...
Principles of the origami art form allow for larger materials to be folded and collapsed into small spaces. And with modular building systems gaining wider acceptance, the applications for components that can be stored and transported with ease have grown. From left, Yi Zhu, a Research Fellow in...

What causes a collapsed lung? There are many ways a collapsed lung can occur but in this case, it was due to the hit Brees took by Kentavius Street of the 49ers which fractured two of his ribs on the left side. Here's a look at the hit fromBad Sports Refson Twitter: ...
why the US unemployment rate rose by 4 percentage points in 24 months; why Bear Stearns was only (and barely) saved by a Federal Reserve bailout and Lehman Brothers collapsed; why many banks are underfunded; and why some totter on the brink, even after a bailout, and may yet vanish. ...
MD 21250The Tacoma Narrows Bridge collapsed on November 1, 1940 due to its inability to stand againstthe strength of the wind.In many physics textbooks, the reason for the collapse is attributed tothe resonation of the bridge in the wind.Engineers have worked on the problem of why i...
Problems in that early construction technology were underscored graphically when the Sylmar quake hit in 1971, causing freeway bridges in that area to bounce like gigantic hammers on their support columns. Several overpasses collapsed. Caltrans engineers responded by affixing heavy steel cables to every...
The bathroom ceiling has collapsed. Rats roam the dark, rubble-strewn halls. "Every day, I go to the fire hydrant to get water for cooking, to clean dishes and to wash up for school," the shy eighth-grade student said as the pop song "We Are the World" blasted through a broken ...
