In chronological order during the year:

light, slowed in one Bose Einstein condensate (BEC), is passed on to another BEC (http://www.aip.org/pnu/2007/split/812-1.html);

electron tunneling in real time can be observed with the use of attosecond pulses (http://www.aip.org/pnu/2007/split/818-2.html);

laser cooling of coin-sized object, at least in one dimension (http://www.aip.org/pnu/2007/split/818-1.html);

the best test ever of Newton’s second law, using a tabletop torsion pendulum (http://www.aip.org/pnu/2007/split/819-1.html);

first Gravity Probe B first results, the measurement of the geodetic effect---the warping of spacetime in the vicinity of and caused by Earth-to a precision of 1%, with better precision yet to come (http://www.aip.org/pnu/2007/split/820-2.html).

The MiniBooNE experiment at Fermilab solves a neutrino mystery, apparently dismissing the possibility of a fourth species of neutrino (http://www.aip.org/pnu/2007/split/820-1.html);

the Tevatron, in its quest to observe the Higgs boson, updated the top quark mass and observed several new types of collision events, such as those in which only a single top quark is made, and those in which a W and Z boson or two Z bosons are made simultaneously (http://www.aip.org/pnu/2007/split/821-1.html);

the shortest light pulse, a 130-attosecond burst of extreme ultraviolet light (http://www.aip.org/pnu/2007/split/823-1.html);

在arXiv.org上发现这么一个文章，北大的研究组做的关于Blog圈的自组织结构的论文。具体内容还没有看，但从摘要上看，应该又是一个关于复杂网络(complex network)模型的应用的研究。有兴趣的可以看一看。

Google Book Search想必大家都不陌生，最近的新闻是它把许多版权已经失去时效的古典名著，当然也有“不”名著，都扫描成册，支持全文的浏览阅读。

本想试试，可是脑袋里想不起什么英文名著，知道的也都是汉语名字，莎士比亚的英语也不会写，于是输入自己研究领域的关键字，发现居然也有大量的书籍可以全文阅读。甚至在高级搜索中锁定最近两年的结果，也可以找到不少资料，不知道Google是怎么处理这些版权的。

一篇最近的IEEE Spectrum的文章，关于科学工作者的职业生涯的（How to climb the academic ladder）。正在读博士或者博士已经“后”了几年的读者值得一读。

里面提到的"Tenure clock"是六年。

What's Up, Postdoc?

By Prachi Patel-Predd

How to climb the academic ladder

Late one night, Richard J. Radke was at his desk, putting together applications for faculty jobs. Nearing the completion of his Ph.D., he was hoping to embark on an academic career. A senior professor he knew well took Radke aside and said, “I hate to tell you this, but it’s going to be brutal,” he recalls. Radke, now an assistant professor in electrical, computer, and systems engineering at Rensselaer Polytechnic Institute, in Troy, N.Y., admits that his professor was right. Even once he’d landed a job, for the first few years he was constantly busy and stressed out as he learned the ropes and started worrying about tenure.

微软气喘吁吁地追着Google跑，推出了Windows Live Academic的测试，面向学术领域，用来对抗Google Scholar。

Windows Live Academic is now in beta. We currently index content related to computer science, physics, electrical engineering, and related subject areas.

Academic search enables you to search for peer reviewed journal articles contained in journal publisher portals and on the web in locations like citeseer.

Academic search works with libraries and institutions to search and provide access to subscription content for their members. Access restricted resources include subscription services or premium peer-reviewed journals. You may be able to access restricted content through your library or institution.

转贴一篇朋友的文章。

实验室研究走到尽头了吗？

听起来有点危言耸听，其实早就不是什么新鲜话题了。1971年医学和免疫学泰斗Burnet在Genes, Dreams and Realities一书中就忧心忡忡地提到：

“None of my juniors seem to be worried as I am by the fact that the contribution of laboratory science to medicine has virtually come to an end.”

要知道当时免疫学还处于黄金时代，医学也是欣欣向荣，是Burnet先知先觉还是我们执迷不悟？

很长时间没有写帖子了，不是没时间，真的是才疏学浅，不知道写些啥，自己的网志也有时间没有更新了。:-(

给大家推荐些资源。在一个国外的BT网站上居然下载到了MIT的教材（也不知道是不是真的），一共700MB，种子不多但是很稳定，象我一样有耐心的话二三十个小时能下完，呵呵。

四个目录分别是：Physics，Math，Computers和Lecture Notes，草草看了一下觉得真的是够全，全是PDF或PS文件，多为扫描而成，加了Bookmarks，相信对这里的读者会有帮助。因为书目巨多，无法一一写出，我把四个分类的文件列表抓成图片，各位可以点击看最大图片，确认是不是真的需要。

本周的《Nature》里，用三篇文章（《Joint effots》《The real death of print》《Start your engines》）组成了一个专题，分别探讨了BLOG，Goolge Book Search和Google Scholar对科学界产生的影响。感兴趣的可以去看看，我这里有一个集合的PDF文件提供下载。
