不管我们的教材更新的多快,都赶不上科学的发展速度。 每分钟,甚至每秒钟,都有新的科学发现和研究发表出来。
如果我们的教材更新的太慢的话,说不定孩子学到的科学已经是过时的,或是不正确的知识了。

在学科学教材的同时, 学习当代科学科技的新发现,新研究,新创新就显的尤为重要。

    很有意思,我转一篇过来看看:

    Calculating crime
                                                    By Stephen Ornes / January 28, 2009                                       

    People who solve crimes look for patterns that might reveal the identity of the criminal. A mathematician from Maryland has come up with tools to help police find crooks.

    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 crooks.
    People who solve crimes look for patterns that might reveal the identity of the criminal. It’s long been believed, for example, that crooks will break the law closer to where they live, simply because it’s easier to get around in your own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect 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 an offender’s home base by combining these patterns with a city’s layout 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 census, or survey, 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.”
