When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.

People who solve crimes look for patterns that might reveal(揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live, simply because it’s easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect(嫌疑犯) who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.

But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal’s home base by combining these patterns with a city’s layout(布局) and historical crime records.

The records of past crimes contain geographical information and can reveal easy targets — that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example, that the younger the criminal, the closer to home the crime.

Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.

The program is just one way to use math to fight crime. O’Leary says that criminology — the study of crime and criminals — contains a lot of good math problems. “I feel like I’m in a gold mine and I’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”

Insomnia is most commonly a side effect of depression, but it can   10be caused by many other ailments (小病痛). To find the   11, doctors first find out the cause by   12a “sleep diary,” in which you record your sleep habits.

A good night’s sleep is created during the day.   16in the beginning or middle of the day, and   17from caffeine, alcohol and cigarettes in the afternoon and evening. After dark, dim (使暗淡) the lights and try to   18stress. Our bodies like consistent (一貫的) patterns, so we should let   19know that it’s time to wind down.

If you can’t fall asleep, keep the lights   20. Try reading a book or listening to soft music. You’ll most likely be asleep.
