QB is designed to serve as your eyes ,ears and voice when you can't be there in person ,Even better , it's mobile , rolls around on two wheels like Rosie and can be navigated remotely via the Web and a Wi-Fi connection .2Telecommuting workers and traveling executives alike could us QB (so named because it is the next in line after the company's prototype QB bot) as a virtual extension of themselves. allowing them to attend meetings , tour facilities or perform walk-throughs of real estate properties , all while controlling the robot from a computer keyboard.3Anybots formally unveiled the remotely controlled robot on Tuesday and plans to start selling QBs by the end of the year .A five-megapixel vedio camera serves as one eye, whlie the other is a laser pointer. A speaker on the crown of QB's head gives it a mouthpiece, a touch-screen monitor on on its forehead enables software maintenance and other input , and a ring of protective rubber around its head makes it look a bit like Olivia Newton-John circa 1981.4Along with the wheels,a self-balancing system and a motor with a top speed of five kilometers per our make the robot mobile . The two-wheel-as opposed to a tricycle or quad-design makes it more maneuverable in tight spaces and helps keep its weight down to about 16 kilograms . The area between the QB'shead and base consists of a length of telescoping plastic that can be adjusted to let the QB stand as tall as 175 centimeters or as short as 81 centimeter.5Although it's unclear if the capacity for remote operation. willUS$15,000 Price tag .Anybots believe its technology will appeal to a new generation of workers who expect to be in contact at all times and in all places .The QB is designed to enable this connectivity without sacrificing “presence”,says Bob Christopher,president and chief operating officer of Anybots ,based in Moutain View,Calif . Bandwidth speed and vedio qu ality continue to improve , but they can’t replace being there , he adds .A test-drive reveals valuable Wi-Fi lesson6 To see how this might work in practice , Scientific American test-drove (from our editorial offices in New York) a QB located at Anybots’s facility in California . Our mossion was to drive across the building’s lobby and ask a second QB (remotely controlled by an Anybots employee) where we could find Erin Rapacki , who does product development for the company , and then proceed to Erin’s l ocation. The session began with logging on to a website set up by Anybots and selecting the IP address of the QB we were to inhabit.7 Once our robot “woke up” and connected to Anybots’s local Wi-Fi network, we used the arrow keys on our keyboard to navigate the QB across the lobby. The controls take some getting used to. Particularly because rugs and other materials on the floor may prevent the Qb from travelling a completely straight line . We easily found the other QB but had difficulty aligning our came ra so that we were staring directly into the other QB’s camera. This wasn’t necessary , because we could hearthe person controlling the other QB loud and clear through the microphone on our robot. Using the arrow keys,we were able to swivel our QB to the left and follow the relatively basic directions we had been given to our destination.8 With a bit more practice, navigation would have been smoother, THE QB features a buit-in lidar(light detection and ranging) system that warns the robot when it is getting too close to an object and slows the robot down to avoid(or at least reduce the impact of) a collision. The QB also has a camera located on the bottom of its “”chin” that points down at its wheels so you can see whether you’re about to drive over a lowe r obstacle(such as someone’s foot).9 The QB’s laser-pointer eye turned out to be useful when greeting people we encountered, including Anybots founder and CEO Trevor Blackwell, who accepted a laser beam in the palm of his hand in lieu of a handshake (a relief ,since the QB has no hands).10 By the time we were ready to leave , we were able to drive our QB back to the Anybots lobby and out the front door. Just past the building’s threshold, we learned a valuable lesson in surrogate navigation: never drive outside the range of your Wi-Fi network. A dropped connection means no cameras and no control over the robot’s navigation, which was especially unfortunate in our case because we were approaching the top ofa ramp down to the parking lot when we lost the signal.11 Danger,Will Robinson.Unit4译文今后远程控制的代理机器人可以为您参加的会议它可能看起来像装在一个真空吸尘器落地灯,但实际上它是Anybots公司最新的代理机器人的QB。

Unit 1搏弈论阿维纳什•迪克斯特&巴里•内尔巴夫搏弈是有关策略的科学。
它试图以数学和逻辑的方法来帮助搏弈者作出决策,在一系列纷繁复杂的搏弈中应采取何种策略来保证自己获得最大利益。
搏弈论研究的搏弈的范围包括了从下棋到抚育儿童,从网球竞技到公司转手。
但是所有的博弈都具有一个共同的特征:相互作用。
也就是说,每一个博弈者的博弈结果取决于所有博弈参与者的策略选择。
在零和搏弈中,搏弈者的利益之间是完全冲突的,因此一方的得利必然导致另一方的损失。
更多具有代表性的例子还有会导致共同得利(正和)搏弈和共同损失(负和)搏弈,同样的情况还会发生在另外一些冲突中。
搏弈论研究的先驱者是普林斯顿数学家约翰•冯•诺依曼。
在早先的一段时间里,研究的重点被放在了完全冲突(零和)搏弈(非合作搏弈)上,其他的搏弈当时被认为是以合作形式出现。
也就是说,搏弈要求参与者共同地选择和实施他们的行为.最近的研究则把重点放在了那些既不属于零和搏弈也不属于绝对合作搏弈的情况上,在这些搏弈中,搏弈者自主地选择搏弈行为,但他们之间的相互关系中充满了合作与竞争。
搏弈行为与我们在中性环境中所作的各种决定有着根本性的不同。
要说明这一点,我们可以思考一下伐木工人和军队将军所作决定之间的不同。
当伐木工人决定要如何砍树时,他不会考虑树木本身会有什么反抗,他所处的环境为中性。
而当将军决定要消灭敌军时,他必须提前预料到并消除敌军的反抗。
与这一例子中的将军相类似,一个搏弈者必须认识到他与其他机智且怀有争胜之心的竞争者之间的相互作用,他自己所作的决定也必须能够同时应对可能出现的合作或冲突。
搏弈的实质是搏弈者采取策略之间的相互依赖性。
这种策略性的相互依赖表现为两个不同的类别:连续策略之间的相互作用以及联立策略之间的相互作用。
就前者而言,搏弈者依次采取行动,每个人都会注意其他搏弈者先前的行为。
就后者而言,搏弈者同时采取行动,每个人都会忽略其他搏弈者当前的行为。
对连续策略博弈中的某一博弈这来说,一个普遍的原则就是放眼前方,及时反思和总结。

Unit 1 Genetically modified foods -- Feed the World?If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions -- and vocal green lobbies -- the idea seems against nature.如果你想在某次晚宴上挑起一场激烈的争论,那就提出转基因食品的话题吧。
对许多人来说,高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。
特别是在有悠久的农业生产传统和主张环保的游说集团的国家里,转基因食品的主意似乎有悖自然。
In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic is out of the bottle.事实上,转基因食品已经成为我们生活重要的一部分。

科技英语阅读教程unit1A(张敏杨秀芬版)

Unit 101 Something in the American psyche loves new frontiers. We hanker after wide-open spaces; we like to explore; we like to make rules but refuse to follow them. But in this age it’s hard to find a place where you can go and be yourself without worrying about the neighbors.美国人的内心深处具有一种酷爱探索新领域的气质。
我们渴求宽敞的场地,我们喜欢探索,喜欢制定规章制度,却不愿去遵守。
在当今时代,却很难找到一块空间,可以供你任意驰骋,又不必担心影响你的邻居。
02 There is such a place: cyberspace. Formerly a playground for computer fans, cyberspace now embraces every conceivable constituency: schoolchildren, flirtatious singles, Hungarian-Americans, accountants. Can they all get along? Or will our fear of kids surfing for dirty pictures behind their bedroom doors provoke a crackdown?确实有这样一个空间,那就是信息空间。
这里原本是计算机迷的游戏天地,但如今只要想像得到的各类人群应有尽有,包括少年儿童、轻佻的单身汉、美籍匈牙利人、会计等。
问题是他们都能和睦相处吗?人们是否会因为害怕孩子们躲在卧室里看网上的淫秽图片而将它封杀?03 The first order of business is to grasp what cyberspace is. It might help to leave behind metaphors of highways and frontiers and to think instead of real estate.2 Real estate, remember, is an intellectual, legal,artificial environment constructed on top of land. Real estate recognizes the difference between parkland and shopping mall, between red-light zone3 and school district, between church, state and drugstore.首先要解决的问题是,什么是信息空间。

s e c t i o n2--1-4科技英语阅读与翻译1 Monograph专著1. The general definition of a monographScientific treatises of book length but otherwise variable format prepared by acknowledged experts onspecialized topics for the benefit of others who have specialized in. or who wish to obtain a specialist'sappreciation of, these topics.2. The value of monographs for scientific researchesThe value of monographs lies in the coherence and comprehensiveness of the information and knowledge theycontain, which is important to the specialized researchers to whom they are directed and, therefore, to theadvancement of science and engineering generally.3. The qualities of the authors of monographsThe authors of monographs should have exceptional breadth and depth of knowledge, and must be able tocollect, collate, analyze, integrate, and synthesize all relevant contributions to the archival literature of thescientific and engineering journals and to add original material as required.4. The differences between monographs and books of conference proceedings Monographs generally are written by specialists for the benefit of other specialists. Textbooks are pedagogicalworks which, even if written on fairly narrow subjects, are designed to serve broader and more juniorreaderships than specialized research communities.5. The differences between monographs and books of conference proceedings Conference papers commonly take the form of premature announcements of new scientific discoveries.Conference proceedings generally have a short shelf life.6. The main components of a monographThe author, title and subtitle, date of publication, dust cover or blurb, content pages, bibliography and index,illustrations, preface and introduction.7. An indication of the book’s su ccessThe number of editions is an indication of the book’s success.8. The function of the blurbIt gives the reader a rapid overview of the contents and approach. It might also say what the book contains andfor whom it is written.2 Academic Journal学术期刊1. The general definition of an academic journalAn academic journal is a peer-reviewed periodical in which scholarship relating to a particular academicdiscipline is published.2. The significance of peer-review processThe peer-review process is considered critical to establishing a reliable body of research and knowledge.3. The definition of review articlesReview articles, also called “reviews of progress”, are checks on the research published in journals.4. One difference between original research articles and review articlesUnlike original research articles, review articles tend to be solicited submissions, sometimes planned years inadvance.5. The places where science journals are authoritatively rankedNatural science journals are categorized and ranked in the Science Citation Index, and social science journalsin the Social Science Citation Index.6. The possible quantitative factors to reflect an academic journal’s prestigeThe number of later articles citing articles already published in the journal, the overall number of citations,how quickly articles are cited, and the average “half-life” of articles.7. The financial resources of humanities and social science academic journals Subsidies by universities or professional organizations and advertising fees by advertisers.8. The role of internet in the production of, and access to, academic journalsThe Internet has revolutionized the production of, and access to, academic journals, with their contentsavailable online via services subscribed to by academic libraries or even in a way of open access.33 Organization of a Scientific Paper科技论文的篇章结构1. In most scientific journals, scientific papers include the following sections Summary or Abstract, Introduction, Materials and Methods, Results, Discussion, Acknowledgments.2. The content of Summary or AbstractIt gives a brief background to the topic, describes concisely the major findings of the paper, and relates thesefindings to the field of study.3. The Introduction section deals with the following two pointsIt describes first the accepted state of knowledge in a specialized field; then it focuses more specifically on aparticular aspect, usually describing a finding or set of findings that led directly to the work described in thepaper.4. The purpose of Materials and MethodsIts purpose is to describe the materials used in the experiments and the methods by which the experimentswere carried out.5. The two ways of organizing ResultsIn some papers, the results are presented without extensive discussion, which is reserved for the followingsection. In other papers, results are given, and then they are interpreted, perhaps taken together with otherfindings not in the paper, so as to give the logical basis for later experiments.6. The purposes of the Discussion sectionThe data in the paper are interpreted; the findings of the paper are related to other findings in the field; thisserves to show how the findings contribute to knowledge, or correct the errors of previous work; some of thelogical arguments are often provided when it is necessary to clarify why later experiments were earned out.7. The reason for combining the Results and DiscussionBecause the data need extensive discussion to allow the reader to follow the train of logic developed in thecourse of the research.8. The difference between the abstracts in Science and those in NatureIn Science, the abstract is self-contained; in Nature, the abstract also serves as a brief introduction to the paper.4 Reading a Scientific Paper科技论文的阅读方法1. The order to understand the major points of the work, you should first read The Abstract.2. Reading the Title and the Abstract serves three purposesFirst, it clarifies whether you in fact know enough background to appreciate the paper. Second, it refreshesyour memory about the topic. Third, it helps you integrate the new information into your previous knowledgeabout the topic.3. When reading in a familiar field, you can skim or even skipThe Introduction.4. The three typical codewordsData not shown, unpublished data, preliminary data.5. The poorly written papers are often related to three types of writersThose who are poor writers; those who do not enjoy writing, and do not take the time or effort to ensure thatthe prose is dear and logical; those who are so familiar with the material that it is difficult to step back and seeit from the point of view of a reader not familiar with the topic.6. The three characteristics of “bad writing”First, the logical connections are often left out. Second, papers are often cluttered with a great deal of jargon.Third, the authors often do not provide a clear roadmap through the paper.7. In better writing, the side issues are dealt with in the following waysThey are relegated to Figure legends or Materials and Methods or clearly identified as side issues, so as not todistract the reader.8. Another problem faced by the readers is that when they seek to understand just the experiment was,they may findThe authors refer back to previous papers; these refer in turn to previous papers m a long chain.。
