化学元素之歌

by Yan on 3月 7, 2008

王鸿飞提到的这个化学元素歌挺好玩的。

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.

Chemistry 3B

by Yan on 11月 23, 2007

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,…

化学语义网

by Yan on 5月 11, 2007

这个视频是 Peter Murray-Rust 去年 9 月在 Google Tech Talks 做的报告。先是批判了一下现有学术出版过程的弊端,实验数据和结果,因各种人为因素不能被同行和大众方便地使用。然后,介绍了他们在化学领域的一些实践,比如用 Google API 和 PubChem 做的一个 Mashup 等等。我特别注意到他说:“Chemistry is the most tractable discipline for the semantic web – most chemistry can be turned into XML with little semantic loss, using Chemical Markup Language and complementary MLs such as XHTML, MathML and SVG.”似乎很有道理。我自然地会想能否把同样的思路应用到其他学科。

他不喜欢 ppt,这个还不太特别;他也不喜欢 pdf,这个就比较有个性了。他说,把语义数据转换成 pdf,实际上破坏了所有东西。而要把 pdf 转换回到语义数据,就像把汉堡包转换回牛一样不可能。:)

所以他用 html 来做报告。看他在报告过程中,不停地点链接,选书签。结果他们的服务器不幸地正好出了问题。。。下面是他报告的摘要。
