Shriveled, slithery, and wily, Gollum is one of the more memorable characters in the Lord of the Rings movies. But it took computers to bring Gollum to life, creating animated images of the character that smoothly blend with the actors on the screen.
( 1 ) The skills of programmers, computer scientists, and software engineers are essential not only for generating special effects in movies but also for creating video games, operating cell phones, searching the Internet, downloading and playing music, and much more.
Nowadays, there are computers in airplanes, cars, television sets, vending machines, and kitchen appliances. All these computers need people who understand how computers work and can provide the necessary instructions. ( 2 )
Unfortunately, the popularity of computer science as a career has been fading in the United States. ( 3 ) says Randy Pausch. He's a computer scientist at Carnegie Mellon University (CHU) in Pittsburgh.
Equally troubling is that fewer than 20 percent of these students are women, he adds.
Computer science has tremendous power to make a big difference in people s lives, says Caitlin Kelleher, a graduate student in computer science at CHU.
( 4 ) Using an interactive computer program called Alice, Kelleher has bade it her mission to show kids all the exciting opportunities that open up when you can talk to these machines in a language that they can understand.
Using Alice, a student can quickly create an animated movie in which characters move about and interact in an imagined 3D world. ( 5 )
The results don t look like Lord of the Rings, but if you give Alice a try, you can experience the immense satisfaction of getting a computer to do what you want it to do - and of showing off your waddling penguins or attacking bugs to friends.
Shriveled, slithery,，和Wily ，咕噜是一个更难忘的字符魔戒电影。但是，在计算机，使古鲁姆的生命，创造动画图片的字符，顺利地融为一体，演员在屏幕上。
（ 1 ）技能的编程人员，计算机科学家和软件工程师是必不可少不仅产生特殊效果的电影，而且为创建视频游戏，经营手机，上网，下载和播放音乐，以及更多。
现在，有电脑，飞机，汽车，电视机，自动售货机，厨房用具。所有这些电脑的人谁需要了解计算机的工作并能提供必要的指示。 （ 2 ）
不幸的是，普及计算机科学作为一种职业已经衰落的美国。 （ 3 ）说，兰迪Pausch 。他是一位计算机科学家在卡内基梅隆大学（储）在匹兹堡。
（ 4 ）采用互动电脑程序爱丽丝凯莱赫已吩咐它的使命，以显示她的孩子们所有的激动人心的机会，开放时，您可以跟这些机器的语言，他们可以理解的。
使用爱丽丝，学生可以快速创建一个动画电影中人物走动和交流的一个想象的3D世界。 （ 5 ）
Domestic wipers generally with 3 months or so tape wear and tear on the more serious, this is a problem because of this rubber compound. Wipers the world's leading manufacturer of rubber has its own unique formula,auto wiper blades, the general domestic wipers rubber come from a number of non-professional manufacturers of these manufacturers rubber production technology and professional wipers have a large gap between manufacturers, it is difficult to ensure product life. Good tape is made of pure natural rubber raw material, while the defects are all used in synthetic rubber,Fashionalwatch.com:Golden Age watches, non-durable. So how to distinguish is a good tape? The first thing to be identified,auto wiper blades, pure natural rubber in the visual is a natural black, while the synthetic rubber,auto wiper blades, black or have some special whiten; then touch,auto wiper blades, pull or roll the tape up any those of force, and then let go of the elastic strip to see if the deformation of serious, was defective; and finally to see whether the blade straight, if there are impurities or a knife-edge above the split was not good, when there will be Wiper waterline, nor qualified. At present, most wipers are graphite strip above, if the powder Mo Shangqu very rough or very easy to fall off, illustrate the wipers are also unsatisfactory.
