看到另一位教授开始blog了。李淼，他是是中科院理论所研究员，研究领域是弦论 (String Theory)，和陈辉同行。他写的《弦论通俗演义》是最近网络上流行的科普书。他的blog，博客李淼，还有在blogcn的旧站。
现在有不少类似 Matlab 的自由科学计算软件：Scilab，Octave，FreeMat，Rlab，而且它们都 mostly compatible with Matlab。单位没有正版 Matlab 的真有必要考虑使用它们，而不是使用盗版。
可是这么多，不知道哪个最好使。：）根据这个人的说法，如果你用Windows，那Scilab最方便，如果使用Unix类操作系统，Octave最合适。
一直很欣赏，奇迹文库以及奇迹笔记。今天点过去，发现转到了blog.ndodo.com。看看这个 ndodo.com 和奇迹的版式非常像，是不是同一批人在做啊。
发现Fallenart的文章：关于实验物理学家斯特凡纳·杜瓦迪的工作 。
提到现代物理学你想到什么？你大一的时候最头疼的公共课？或者天书一样数学推导与图表，又或者如爱因斯坦般不修边幅的物理学家？当然，这些都是物理学，不过仅仅是物理学的一面而已。现代物理学经过上百年的发展已经深入到我们生活的每一个角落里，而且，事实上现代的物理学离终点还差的太远，新的研究方向，待解决的问题一直在不断的涌现。虽然二十世纪上半叶那样的物理学神话时代现在看似已经不见踪影，但是今天全新的物理学发展轨迹也一定会让你惊讶不已的。本文中的物理学家杜瓦迪博士，他可以说是当今实验物理学的一个异数人物，也可以说是典型人物。现代物理枝叶之繁盛，与生活交叉之紧密，在此人身上都能看出来。了解他的工作之后，你大概才会恍然大悟，原来，这也是物理，这也是物理学家。
Global Nanotechnology Literature

不知道为什么会收到这个邮件，我又不是做纳米材料的。其中涉及到中国，所以贴出来。我想没有版权问题，既然他们连我都发送。

Subj: Global Nanotechnology Literature
Two recent reports (1, 2) contain a text mining survey and analysis of the global nanotechnology literature, and should be of use to nanotechnology research performers, managers, planners, sponsors, evaluators, vendors, and implementers/ users.
“The Structure and Infrastructure of the Global Nanotechnology Literature” identifies the main nanotechnology literature infrastructure (prolific authors, Centers of Excellence, countries) and technical structure (pervasive technical thrusts and thrust relationships). “The Seminal Literature of Nanotechnology Research” identifies the documents most highly cited by the global 2003 nanotechnology literature, including vintage and very recently cited documents. It also examines the evolution of journals that have assumed prominence in publishing these seminal documents. Some highlights of these documents include:
* The Far Eastern countries have expanded nanotechnology publication output dramatically in the past decade.
* The Peoples Republic of China ranks second to the USA (2004 results) in nanotechnology papers published in the Science Citation Index (SCI), and has increased its nanotechnology publication output by a factor of 21 in a decade.
* Of the six most prolific (publications) nanotechnology countries, the three from the Western group (USA, Germany, France) have about eight percent more nanotechnology publications (for 2004) than the three from the Far Eastern group (China, Japan, South Korea).
* While most of the high nanotechnology publication-producing countries are also high nanotechnology patent producers in the US Patent Office (as of 2003), China is a major exception. China ranks 20th as a nanotechnology patent-producing country in the US Patent Office.
* China has minor representation in the most highly cited nanotechnology documents
* Over the past decade, Science magazine has contained about 2-3% of total nanotechnology publications (citation frequency threshold of three), but over 40% of the most highly cited nanotechnology publications.
