Charlie studied Chemistry in a famous college for four years. He studied hard and did well in all his subjects. He hoped to become a good teacher. This year he left the college and began to work in a middle school. He likes his students and wants them to get good marks so he does his best to make his classes lively and interesting.

  One day he carefully explained a chemical reaction(反应)to the students of Grade 2 in the chemistry lab.

“Be careful. Everyone,” he said loudly. “Before I make the experiment, there’re twenty five atoms of carbon（碳原子), but after I finish it, there’re twenty four atoms of carbon left!”

He stopped to watch the classroom and hoped his students would go on explaining it. But the young men looked at each other and nobody answered him. He had to ask, “What happens? What makes the atom disappear? ”

The classroom was very quiet and none of the students looked at their teacher.

“Who can tell us where it has gone?”

Suddenly a soft voice came from the back row, “We did not see anybody leave the lab!”

Nanda sees a wearable computer as a handbag, one that’s built out of four-inch squares and triangles of fabric (织物), with tiny computer chips embedded (嵌入) in it. It looks, feels and weighs like your typical leather purse.

That’s where the similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf (围巾).

Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices (装置), part of next generation of wearable computers, could become common within a few years. DuPont created new super strong fibres that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle.

As a result, these new wearable devices are different from the heavy and silly types of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike the old types, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse.

Here’s how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet. In turn, sensors on your purse’s handles will inform the computer that you’ve picked up the purse and are ready to go.

Already, these new kinds of wearable devices are applied in markets like auto repair, emergency services, medical monitoring-and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years—making for a booming market for wearable computers that don’t look like something out of science fiction.
