Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now the website BookCrossing.com turns the page on the traditional idea of a book group.
Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.
Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”
Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.
People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.
BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

PITTSBURGH — For most people, snakes seem unpleasant or even threatening. But Howie Choset sees in their delicate movements a way to save lives.
The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters or other emergencies.
Dan Kara is president of Robotics Trends, a Northboro, mass-based company that publishes an online industry magazine and runs robotics trade shows. He said there are other snake-like robots being developed, mainly at universities, but didn't know of one that could climb pipes.
The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick (操纵杆). They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes.
Built from lightweight materials, the robots are about the size of a human arm or smaller. They can sense which way is up, but are only as good as their human operators, Choset added.
Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable roles.
"It just allows us to do something we've not been able to do before," Stover said, "We needed them yesterday."
He said sniffer dogs are still the best search tool for rescue workers, but that they can only be used effectively when workers have access to damaged building.
Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster.
Choset said the robots may not be ready for use for another five to ten years, depending on funding.
