The Millennium Bridge in London, England, which opened in 2000, became famous for its "wobbly" motions after crowds of pedestrians moved across it. Different theories into the nature of the bridge motion were developed, one of which was highlighted in the May 2009 issue of ASCE's Civil Engineering Magazine in an article entitled "Bio-mechanics Research Yields Clues to Millennium Bridge Wobble." Dr. Kareem has provided some insightful follow-up comments to this article.

Making the most of storm damage

In March of 2008, a tornado outbreak made its way through the city of Atlanta, GA. Roofs were damaged on low rise structures, trees were uprooted and glass damage was common to the high rise structures in the tornado's path. A year later, the city and building owners chose to make the best of the situation by rebuilding "Green".

Trust and the Internet

The aim of the "TechnoCrowd" is to amass many different points of view and opinions into one space, giving readers/users the ability to parse that information for new concepts and ideas. However, with the freedom to express those opinions, it is the responsibility of the reader to decide what is true and what is false for themselves.

Sites like Wikipedia are populated by anyone with a computer, while the task of verifying that information falls upon everyone else. To assist with fact checking, researchers at UC Santa Cruz are developing a system to parse common sites, like Wikipedia, and color code information in such a way to give a trustworthiness measure based on the reliability of the person posting and the information itself.
