Researchers have developed new software using smart phones¡¯GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects£®The software could eventually allow smart phone-armed soldiers to target the location of their enemies£®On the home front£¬the software could be used by everyone£¬including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it£®
¡°The great advantage of a Smartphone is that it provides so many tools in a single£¬readily available£¬relatively inexpensive package£¬¡±said Qia Wang£¬a doctoral student who led the development of the software£®¡°For example£¬on the battlefield£¬a soldier needs a rangefinder£¬compass£¬GPS and other tools to get information before calling in an air strike£®With our software£¬the soldier can have all those instruments in one device that can be purchased off the shelf£®When that soldier returns from War£¬she can use the same Software to protect her family by clocking a speeder near her children¡¯s school and catching the criminal on video£®¡±
Wang and his colleagues developed their software to locate and track£º
Targets of known size¡ªwhen the size of the target is known£®a single image is enough to pinpoint the target¡¯s location£®
Targets of unknown size¡ªIf the exact size of a target is unknown£¬the software uses two images to triangulate the location of the target¡¤
Moving targets¡ªBy taking a short video of a moving target£¬the smartphone software can calculate how fast the target is moving and in what direction it is going.
¡°Currently£¬our software is limited by the physical abilities of smartphone hardware£¬but the devices are improving rapidly£¬¡±Wang said£®¡°We expect that improvements in GPS accuracy£¬battery life and camera resolution will allow our software to make even more accurate observations£®¡±

Many years ago£¬a French naturalist£¬the Count de Buffon£¬wrote some books about natural history£®The books were a great success even though some critics did not like them£®Some critics said£¬¡°Count Buffon is more of a poet than a scientist£®¡±
Thomas Jefferson did not like what the Count had said about the natural wonders of the New World£®It seemed to Jefferson that the Count had spoken of natural wonders in America as if they were unimportant£®
This troubled Thomas Jefferson£®He too was a naturalist£¬as well as a farmer£¬inventor£¬historian£¬writer and politician£®He had seen the natural wonders of Europe£®To him£¬they were no more important than those of the New World£®
In 1788£¬Thomas Jefferson wrote about his home state£¬Virginia£®While writing£¬he thought of its natural beauty and then of the words of the Count de Buffon£®At that moment£®Jefferson created a new word¡ªbelittle£®He said£®¡°The Count de Buffon believes that nature belittles her productions on this side of the Atlantic£®¡±
Noah Webster£¬the American word expert£¬liked this word£®He put it in this English language dictionary in 1806£¬¡°Belittle¡ªto make small£¬unimportant£®¡±
Americans had already accepted Jefferson¡¯s word and started to use it£®In 1797£¬the Independent Chronicle newspaper used the word to describe a politician the paper supported£®¡°He is an honorable man£¬¡±the paper wrote£¬¡°so let the opposition try to belittle him as much as they please£®¡±
In 1872£¬a famous American word expert decided that the time had come to kill this word£®He said£¬¡°Belittle has no chance of becoming English£®And as more critical writers of America£¬like those of Britain£¬feel no need of it£¬the sooner it is forgotten£¬the better£®¡±
This expert failed to kill the word£®Today£®belittle is used where the English language is spoken£®
