• 摘要

美国一家网站近日根据5 条标准——环境、收入、工作前景、身体要求和压力， 对美国的200种工作进行了评估，并从中评出了20 种最佳和20 种最差工作。出人意料的是， 数学家位居最佳工作首位。

这一评估基于来自美国劳工统计局和人口调查局的数据。根据这一评估， 数学家成为最佳工作的部分原因在于，他们拥有良好的工作环境，在室内工作且不会受到有害气体或噪音等的伤害。他们也不会像消防员、机修工和水管工那样需要做举重、涂抹或蹲伏的工作。

任职于旧金山一家软件公司的38 岁数学家Jennifer Courter说：“数学家不仅仅是每个人在学校里必须学习的无聊学科，它是解决问题的科学。”

收入也是此次评估的一个重要标准，根据收入平均值和增长潜力， 数学家的年收入被确定为94160 美元。而Courter 说她的薪水要高于这一数目。

名列最佳工作榜单2 到10位的分别是保险精算师、统计员、生物学家、软件工程师、电脑系统分析员、历史学家、社会学家、工业设计师和会计师。而被评为最差工作的是伐木工，工作具危险性且收入低，年收入为32124 美元。名列最差工作榜单2 到10 位的分别是畜牧工、出租车司机、海员、急救员、垃圾收集工、焊接工、码头工、炼铁工和建筑工。

Scientist: Four golden lessons STEVEN WEINBERG Steven Weinberg is in the Department of Physics, the University of Texas at Austin, Texas 78712, USA. This essay is based on a commencement talk given by the author at the Science Convocation at McGill University in June.

When I received my undergraduate degree — about a hundred years ago — the physics literature seemed to me a vast, unexplored ocean, every part of which I had to chart before beginning any research of my own. How could I do anything without knowing everything that had already been done Fortunately, in my first year of graduate school, I had the good luck to fall into the hands of senior physicists who insisted, over my anxious objections, that I must start doing research, and pick up what I needed to know as I went along. It was sink or swim. To my surprise, I found that this works. I managed to get a quick PhD — though when I got it I knew almost nothing about physics. But I did learn one big thing: that no one knows everything, and you don't have to.

Another lesson to be learned, to continue using my oceanographic metaphor, is that while you are swimming and not sinking you should aim for rough water. When I was teaching at the Massachusetts Institute of Technology in the late 1960s, a student told me that he wanted to go into general relativity rather than the area I was working on, elementary particle physics, because the principles of the former were well known, while the latter seemed like a mess to him. It struck me that he had just given a perfectly good reason for doing the opposite. Particle physics was an area where creative work could still be done. It really was a mess in the 1960s, but since that time the work of many theoretical and experimental physicists has been able to sort it out, and put everything (well, almost everything) together in a beautiful theory known as the standard model. My advice is to go for the messes — that's where the action is.

My third piece of advice is probably the hardest to take. It is to forgive yourself for wasting time. Students are only asked to solve problems that their professors (unless unusually cruel) know to be solvable. In addition, it doesn't matter if the problems are scientifically important — they have to be solved to pass the course.But in the real world, it's very hard to know which problems are important, and you never know whether at a given moment in history a problem is solvable. At the beginning of the twentieth century, several leading physicists, including Lorentz and Abraham, were trying to work out a theory of the electron. This was partly in order to understand why all attempts to detect effects of Earth's motion through the ether had failed. We now know that they were working on the wrong problem. At that time, no one could have developed a successful theory of the electron, because quantum mechanics had not yet been discovered. It took the genius of Albert Einstein in 1905 to realize that the right problem on which to work was the effect of motion on measurements of space and time. This led him to the special theory of relativity. As you will never be sure which are the right problems to work on, most of the time that you spend in the laboratory or at your desk will be wasted. If you want to be creative, then you will have to get used to spending most of your time not being creative, to being becalmed on the ocean of scientific knowledge.

Finally, learn something about the history of science, or at a minimum the history of your own branch of science. The least important reason for this is that the history may actually be of some use to you in your own scientific work. For instance, now and then scientists are hampered by believing one of the over simplified models of science that have been proposed by philosophers from Francis Bacon to Thomas Kuhn and Karl Popper. The best antidote to the philosophy of science is a knowledge of the history of science. More importantly, the history of science can make your work seem more worthwhile to you. As a scientist, you're probably not going to get rich.Your friends and relatives probably won't understand what you're doing. And if you work in a field like elementary particle physics, you won't even have the satisfaction of doing something that is immediately useful. But you can get great satisfaction by recognizing that your work in science is a part of history. Look back 100 years, to 1903. How important is it now who was Prime Minister of Great Britain in 1903, or President of the United States What stands out as really important is that at McGill University, Ernest Rutherford and Frederick Soddy were working out the nature of radioactivity. This work (of course!) had practical applications, but much more important were its cultural implications. The understanding of radioactivity allowed physicists to explain how the Sun and Earth's cores could still be hot after millions of years. In this way, it removed the last scientific objection to what many geologists and paleontologists thought was the great age of the Earth and the Sun. After this, Christians and Jews either had to give up belief in the literal truth of the Bible or resign themselves to intellectual irrelevance. This was just one step in a sequence of steps from Galileo through Newton and Darwin to the present that, time after time,has weakened the hold of religious dogmatism. Reading any newspaper nowadays is enough to show you that this work is not yet complete. But it is civilizing work, of which scientists are able to feel proud.

环球科学记者虞骏

托尼·海(Tony Hey)博士曾是一位粒子物理学家，现在专门为计算技术和其它科学研究牵线搭桥。和他的老朋友万维网之父蒂姆·伯纳斯-李(Tim Berners-Lee)一样，他也在关注网络及计算技术的应用——不过他关注的方向并非社会生活，而是科学研究。2008年11 月5 日，作为微软公司技术计算副总裁，他在北京参加了微软亚洲研究院为庆祝建院十周年而举办的“创新日”活动，本刊记者对他进行了专访。

《环球科学》：万维网的发明，最初是为了方便粒子物理学家之间的合作交流，如今已经极大地改变了我们的日常生活。而你一直倡导的eScience， 目的也是为科研合作交流提供平台和工具。eScience 的提出是否和万维网一样，与粒子物理学有着不解之缘呢？

托尼·海：我以前就是一名粒子物理学家， 目前在英国科学技术办公室任职， 工作就是负责英国的eScience 项目。eScience 这个单词是英国科学技术局研究理事会前任会长约翰·泰勒(John Taylor) 提出的。他经常与粒子物理学、生物学、环境科学等领域的研究人员合作，知道他们早就有一个愿望：有一天计算能够像网络搜索一样变成一项服务。这促使他提出了eScience这个概念：由计算科学家提供平台或者工具，帮助其它科学家更好地完成研究工作。粒子物理学对网络及计算能力的要求很高。明年，大型强子对撞机将开始产生海量实验数据，粒子物理学家必须把这些数据分散到世界各地，供分布在全球的上千名参与合作的物理学家分析和计算之用。为此，他们建造了所谓的“ 计算网格”， 通过这个网络把不同部门的计算机联网在一起，你可以把计算任务分散到网格上的任何一台计算机上去执行。(参见《环球科学》2008 年3 期《LHC 撞开发现之门》一文) 不过，粒子物理学家是一个十分特殊的群体——他们非常“聪明”，为了达成目的不介意在自己的机器上安装上千万条硬件连接线。根据我的经验，生物学家、化学家和环境科学家就没有这么“聪明”了。他们不愿意自己动手去安装大量软硬件，而是想得到一些“网络2.0” 式的服务来搞定这些棘手问题，好让他们专心从事自己领域内的研究工作。事实上，如何让这些不太“聪明” 的科学家方便地使用我们所提供的合作技术和数据处理技术， 这是eScience 所面临的真正挑战。

《环球科学》：在各类学术期刊上发表论文是最为传统的学术交流方式。随着互联网的发展，在线学术交流日益普遍，比如把学术论文发表在arXiv 电子文库实现共享。与这些方式相比，eScience在学术交流方面能够带来哪些便利？

托尼·海：我曾经在英国南安普顿大学担任电子和计算机科学学院院长。过去15 年来，学术期刊的价格一直在飙升，每年至少上涨10%，但是学院图书馆的经费每年最多增长3% 。所以每到年底，我都要痛苦地抉择： 明年到底要舍弃哪一本。我甚至没有经费去订阅新的期刊，因此也就无法为学院拓展新的研究方向。这件事清楚地表明，传统的学术交流模式已经过时了。但是新模式应该是什么样子，还没有人知道。
在我以前工作过的英国南安普顿大学，我坚持这样一种做法： 所有公开发表的作品，包括研究论文、会议文集、访谈记录、数据甚至软件，学院都必须保留一份电子版本。这些资料随后被汇总成一个学院级的研究资料库。我认为，未来的大学图书馆所扮演的角色，就相当于大学所有脑力劳动成果的监护人。这些数据库通过整合来实现文献共享。
我相信，计算技术将彻底变革学术交流的面貌。许多拉美国家已经把所有的研究论文汇集在一起，建立了一个名叫SciELO 的数据库。由于拉美地区语言环境复杂，这些论文使用的语言也五花八门，有西班牙语、葡萄牙语，还有英语。因此，我们在这个数据库中整合了一套在线机器翻译服务。如果设置把葡萄牙语翻译成英语，点击需要查阅的葡萄牙语论文，旁边就显示在线翻译的英语版本。这项功能很受用户欢迎，反响热烈。这个数据库中的科研论文，每个人都可以免费访问并阅读。这些数据库都建立在SQLserver 的基础之上，不光可以添加论文，还可以储存原始数据。未来， 数据库中的论文都会有链接指向原始数据， 方便阅读者查阅调用。我们正在与美国约翰斯·霍普金斯大学及《天体物理学报》(Astronomy Physics Journal) 展开合作，尝试将天文学领域的论文与原始数据链接起来。事实上，在查阅文献的时候，不光可以找到这篇论文，看到原始数据，还可以将网络上的一切相关信息全显示出来。所有这些资料都通过XML 标签绑定在一起，将来通过语义网能够很方便地查询。
除了论文和数据的共享以外，我们与大英图书馆(British Library) 合作的“ 研究信息中心”项目，还允许用户围绕数据资料做一些其它的事情。你可以开博客，写维基，点评数据库中的论文，甚至能够建立“ 社交圈”，选择让一部分人看到你的评论，另一些人则看不到。把类似于“网络2.0” 的技术结合到科学研究之中， 会是一件非常有趣的事情。这样的论文数据周边服务已经出现。
现在，你已经可以从BioMed Central 订阅一种名叫“Faculty of 1000” 的专业服务了。这家电子出版机构聘请一千多位专家，从生物医药领域每个月发表的论文中，选出他们最喜欢和最不喜欢的，并进行点评。你可以阅读这些著名科学家的评论，并且把论文品味与你相似的科学家筛选出来，重点关注他们推荐的论文。

《环球科学》：今年第6 期《环球科学》杂志提到的“ 科学2.0” 引发了巨大的争议，因为这可能会让剽窃者有可乘之机。eScience 的数据分享模式是否也可能为剽窃者打开方便之门？

托尼·海：确实有这方面的担心，但是在不同的领域， 对待这个问题的方式也不一样。在物理学界，许多论文在正式出版之前，草稿会先发表在arXiv 电子文库当中。但是，物理学界已经达成共识：草稿在arXiv 上发表的日期就是论文的正式出版日期。这样就杜绝了从草稿中剽窃想法的可能。而在生物学领域，科学家在正式论文发表之前，绝对不会让别人先看到内容。在艺术界和人文学科方面，他们的理念不同，做法也不相同。

《环球科学》：科学进步有哪些特点适合eScience 的发展？未来它的前景如何？

托尼·海：科学变化的一个重要特点就是， 以后的科学研究会涉及越来越大量的数据。未来的科学家在从事科学研究时， 需要从不同的地方甚至不同的领域获取数据，加上自己的数据分析计算，进而得出新的成果。要完成这样的工作， 需要用到许多不同的技能， 数据共享和计算能力肯定是不可或缺的。eScience 会为科学家提供众多技术，帮助他们轻松执行计算，发布研究成果，最大程度地实现资源共享及利用。我相信，eScience 能够应用于各种学科，包括自然科学和工程学，甚至艺术、人文及社会科学。日本东京大学的池内克史(Katsushi Ikeuchi) 教授将计算科学与遗产保护结合起来，他称之为eHeritage(e 遗产)；把计算科学与工程学结合起来， 或许可以称为eEngineering(e 工程)。未来，字母“e” 可能不会再被特别指出，因为它将成为我们研究科学的方式和工具，就像我们今天浏览万维网一样方便简单。

主 题： Spring School on Fluid Mechanics and Geophysics at IMS and fund are available for students

The Institute for Mathematical Sciences at the National University of Singapore will host the Spring School on "Fluid Mechanics and Geophysics of Environmental Hazards'' duirng 19 April -- 2 May, 2009 and fund support for students are available.

Organizing Committee

Keith Moffatt (University of Cambridge) -- Chair
Boo Cheong Khoo (National University of Singapore) -- Co-Chair
Pavel Tkalich (National University of Singapore) -- Co-Chair
Weizhu Bao (National University of Singapor
Tieh Yong Koh (Nanyang Technological University)
Shie-Yui Liong (National University of Singapore)

Overview:

Environmental hazards, such as tsunamis triggered by earthquakes, tropical cyclones,monsoon flooding, volcanic eruptions and landslides, are all too familiar in Asia and the Pacific region, and have been the cause of catastrophic disasters. These hazards are a consequence of mechanical processes in the earth, ocean and atmosphere, and in order to understand them and hence to develop well-informed strategies for the mitigation of future disasters, it is necessary to develop sound scientific theory based on geophysical observations and data, the principles of fluid and solid mechanics, and an appropriate combination of mathematical and computational analysis.

This School is intended to focus on fluid mechanical aspects, and is aimed at students who have already graduated in mathematics, physics or engineering, and who wish to undertake research in this broad area. It is intended to bring students rapidly to current research frontiers in the fluid mechanics of environmental hazards. The School will start with introductory and motivational lectures on the fundamentals of geophysical fluid dynamics, and on geophysical hazard and risk in atmosphere and ocean contexts, and will then focus on four specific environmental hazards:
(i) typhoons and tropical cyclones; (ii) monsoons and flooding; (iii) tsunamis; and(iv) pollution of atmosphere, ocean and the urban environment.

The School will include workshop activity in which groups of students will study key papers cited by the lecturers, and will be encouraged to identify and formulate new model problems that need to be solved in each of the above four areas. In this way, it is envisaged that the students will be fully involved in active and collaborative research activity.

Fund support for students:

Student registration is now invited. Grants to cover travel and local subsistence costs will be awarded on a competitive basis. Applications from students resident in Bangladesh, China, India, Indonesia, Korea, Malaysia, Philippines, Sri Lanka, Thailand and Vietnam, as well as Singapore, are particularly encouraged. Limited places may be available for applicants from Australia, New Zealand, Japan, or further afield.
