The Element's Song

Lyrics by Tom Lehrer
Music by Sir Arthur Sullivan

There's antimony, arsenic, aluminum, selenium,
And hydrogen and oxygen and nitrogen and rhenium
And nickel, neodymium, neptunium, germanium,
And iron, americium, ruthenium, uranium,
Europium, zirconium, lutetium, vanadium
And lanthanum and osmium and astatine and radium
And gold, protactinium and indium and gallium
And iodine and thorium and thulium and thallium.

There's yttrium, ytterbium, actinium, rubidium
And boron, gadolinium, niobium, iridium
And strontium and silicon and silver and samarium,
And bismuth, bromine, lithium, beryllium and barium.

There's holmium and helium and hafnium and erbium
And phosphorous and francium and fluorine and terbium
And manganese and mercury, molybdinum, magnesium,
Dysprosium and scandium and cerium and cesium
And lead, praseodymium, and platinum, plutonium,
Palladium, promethium, potassium, polonium,
Tantalum, technetium, titanium, tellurium,
And cadmium and calcium and chromium and curium.

There's sulfur, californium and fermium, berkelium
And also mendelevium, einsteinium and nobelium
And argon, krypton, neon, radon, xenon, zinc and rhodium
And chlorine, carbon, cobalt, copper,
Tungsten, tin and sodium.

These are the only ones of which the news has come to Harvard,
And there may be many others but they haven't been discovered.

郑强是浙江大学一位高分子材料教授，但以关于教育的生动的演讲闻名，被许多学生爱称为“愤青教授”“强哥“。

优酷有郑强教授的演讲专题，口才极好，和说相声一样。

Also covered: Orthopedics, Dental, Cardiovascular, and Soft Tissue Reconstruction. Professor Pruitt's current research is focused on fatigue and fracture micromechanisms, cyclic damage zones, and evolution of structure due to cyclic loading and environment in advanced polymers and biomaterials; tribology of...

Chemistry 3B: Chemical Structure and Reactivity. Spring 2006. Professor Peter Vollhardt. Chemistry 3B represents the second semester of the standard organic chemistry series at UC Berkeley. It covers conjugation, aromatic chemistry, carbonyl compounds, carbohydrates, amines, carboxylic acids, amino acids, peptides, proteins, and nucleic acid chemistry. Ultraviolet spectroscopy and mass spectrometry will be introduced. Organic chemistry is a specific discipline within the subject of chemistry. It is the scientific study of the structure, properties, composition, reactions, and preparation of chemical compounds of carbon and hydrogen, which may contain any number of other elements, such as nitrogen,...

Integrative Biology 131: General Human Anatomy. Fall 2005. Professor Marian Diamond. The functional anatomy of the human body as revealed by gross and microscopic examination. The Department of Integrative Biology offers a program of instruction that focuses on the integration of structure and function in the evolution of diverse biological systems. It investigates integration at all levels of organization from molecules to the biosphere, and in all taxa of organisms from viruses to higher plants and animals. The department uses many traditional fields and levels of complexity in forging new research directions, asking new questions, and answering traditional questions in new ways.

Search Engines: Technology, Society, and Business. The World Wide Web brings much of the world's knowledge into the reach of nearly everyone with a computer and an internet connection. The availability of huge quantities of information at our fingertips is transforming government, business, and many other aspects of society. Topics include search advertising and auctions, search and privacy, search ranking, internationalization, anti-spam efforts, local search, peer-to-peer search, and search of blogs and online communities. The Instructor, Dr. Marti Hearst, is an associate professor in the School of Information at UC Berkeley, with an affiliate appointment in the Computer Science Division.

Thirty years ago, Susskind and Hawking met in Werner Erhard's mansion. In that house, Hawking explained why he thought that the information was lost during black hole evaporation. Susskind was the only one who really understood this heresy - wrong heresy, as we know today. via: Lumo

地球人都知道，今天18时05分，我国在西昌卫星发射中心用长征三号甲运载火箭将嫦娥一号卫星成功送入太空。从优酷上找个视频贴贴。

　　今后一段时间，嫦娥一号在地球轨道上将进行４次变轨，让卫星不断加速，进入地月转移轨道。到达月球引力范围后，将通过３次近月制动，建立起距月球２００公里的绕月球两极飞行的圆轨道，进行绕月探测飞行。

　　此次嫦娥一号绕月探测飞行将完成四大科学探测任务：获取月球全表面三维图像；分析月球表面化学元素和物质类型的含量和分布；探测月壤特性；探测４万至４０万公里间地月空间环境。

这四项任务要获取的数据，不知道美国是否已经有了。

下面一个视频来自【东方卫视《东方新闻》】，有各国早期探月珍贵视频资料。

Google 在 Google Earth 4.2 版本里面新加了个功能叫 Google Sky，现在可在 Google Earth 里面 浏览天空中上亿的星球和星系了。

下面是个演示视频：

由美国国家自然基金会(National Science Foundation),公共科学图书馆(Public Library of Science)和圣迭戈超级计算中心(San Diego Supercomputer Center)合作推出了一个新的SciVee的网站，可以被认为是YouTube的Science版本。科学家们可以在上面上传论文或者以讲座的形式来展示他们的研究成果。旨在给描述科学一个除了解决程式化的和难以读懂的科学论文以外的别的方法。

看了一下 scivee，因为是 PLoS 做的，所以内容多是生物类的。另外，发现它又是用 drupal 做的，drupal 真是很强大，而且很受科学群体的欢迎。

"纪念量子力学Everett诠释50周年的会议于2007年7月19日～21日在牛津大学哲学中心举行，来自哲学和物理学战线的专家学者们齐聚一堂，各抒己见。现在视频已全部上网，对MWI感兴趣的可以去会议网站下载。此外，据该网站的消息，BBC4将在今年推出关于Hugh Everett III生平的记录片。"

via: Solidot。量子力学 Everett 诠释，即多世界解释，据说接受它的人现在越来越多了。网站上确实有不少有趣的内容。Solidot 在报道科技新闻方面比格致还要尽心尽力，我们真该更加努力啊。

去年 ESO 一个关于激光导引星的新闻视频，比较火星了。但里面有激光导引星原理的介绍，还是有些观看价值的。

在这个视频里可以看到如何用柠檬，镀锌的钉子，以及铜币做电池；如何用四个柠檬点亮一支发光二极管；如何用两个两只柠檬驱动一个计算器。

视频的作者是 Hila Science Camp，这里有制作柠檬电池图解说明，看到早有人把它翻译成中文了。

很有意思的激发孩子们对科学的兴趣的材料吧，相关的还有一个用醋做电池的视频演示。

Hila Science Camp 网站上还有不少其它科普项目和视频资料。

简单的演示，效果还是很炫的。容器里的气体是六氟化硫，无色又很重。via：Living the Scientific Life.

最近，大家似乎都没有心思写严肃的 blog，就贴点轻松的吧。

有个大个子名字叫“风”，他空有一身能量，但一无用处。沦落到混混的地步，没人理解。直到有一天。。。

这是个关于风力发电的广告片，由 Nordpol+ Hamburg 帮 EPURON，德国一家可再生能源公司，制作。有趣，对风力发电的阐释也很到位，我非常喜欢。

不知道格志的朋友里面有没有做相关工作，个人觉得做可再生能源很有前途，而且很有意义啊。
