2:29 PM | A Bridge Too Far for Fiber-Reinforce Polymers
An anonymous reader alerted me to a news story that features polymers in a novel use, but at the same time, not in a good light.The story concerns the Morrison Bridge in Portland, Oregon, one of the most heavily used bridges in that state. The bridge is a double-leaf bascule bridge. For these types of bridges, there is a counterweight that is used to lift the leafs. This places restrictions on how heavy each leaf can be. The original bridge surface was made of steel grating, but was slippery […]

3:51 AM | The Case of Jagger the Irish Setter
At the beginning of March, it was reported that a European show dog, a 3-year old Irish Setter named Jagger, had died with possible suspicious circumstances while competing in the Crufts show in the United Kingdom. Toxicological analyses were completed on specimens drawn during autopsy of the animal. According to the latest reports, the dog’s blood was positive for aldicarb and carbofuran - two substances that should not be found. At all.What are aldicarb and carbofuran?  They […]

9:32 PM | "Educators, generals, dieticians, psychologists, and parents program. Armies, students, and some..."
“Educators, generals, dieticians, psychologists, and parents program. Armies, students, and some societies are programmed. An assault on large problems employs a succession of programs, most of which spring into existence en route. These programs are rife with issues that appear to be particular to the problem at hand. To appreciate programming as an intellectual activity in its own right you must turn to computer programming; you must read and write computer programs—many of them. […]
