Snake Robots

by 孙尉翔 on 2月 18, 2009

A review on snake-inspired robot design was published on the IOP journal, Bioinspirations and Biomimetics, 2009 ,4, 021001. DOI: 10.1088/1748-3182/4/2/021001. The introduction paragraphs of the review described several advantages of snake-like robot compared with other types of design, which is quite interesting to read. But I did not go into the detail of the review. There are images of various design of snake robots in this paper. And this reminds me to search some videos in It seems that these robots don’t just move like snakes. They also moves like worms, or something not seen in nature.

Liquid Mirror

Liquid Mirror Telescope

The first time I heard that liquid mirrors worth studying was from a Nature’s News & Views article.
Rotating liquid that creates a parabolic surface enables human to
conceive about really big telescopes that have to be built on the moon.
The Nature article praised the use of ionic liquids (ILs)
— liquids that are hardly volatile — for liquid mirror support, because
in the moon the working environment is vacuum. And it is also cold
there, so the liquid mirror should also melt at as low a temperature as

Man-Made but Living Systems – Bio Besides Mimetics and Inspirations

by 孙尉翔 on 2月 18, 2009

According to which though is not often desirable, the meaning of the word biomimetics does not include the direct utilization of the functional part of living structures. We have found lotus leaves superhydrophobic. But biomimetically we didn’t directly grow lotus crops for water-repelling coatings, nor did we try to culture similar layer from lotus tissue. Rather, we got ‘inspired’ and started ‘mimicking’ the structure by purely artificial technologies we are familiar with. Similar situation is in computer science—obviously we didn’t try to clone some people exclusively for intellectual production, leaving us a comfortable yet improving future without necessity to think over anything complex. Rather, we turn to silicon-based computers and only wish these computers can become smarter by mimicking the logical structure of brain—what the cyberneticists are doing.

Do Chinese Civilians Hate Scientist?

这是我在Nature Network博客上的一篇文章,最新得知已经被推荐到Nature.com主页上了。

UPDATE: The whole post was revised to avoid misunderstanding. Some parts are bolded.

The first line is the simplified Chinese of the phrase ‘experts and professors’, and the second line is a very popular homophonous variation of the phrase and the meaning changed to ‘rock owner and roaring creature’

Research shows that among several countries in the world China ranks very low in science literacy of the public, especially in understanding the methodology of science as well as the relationship between science and society.

Yes. If you start a poll (I mean a undisturbed, full democratic poll) among the people here, whether to dismiss the Chinese Academy of Sciences and that of Engineering, the answer is very likely to be positive.

Two committee members from Chongqing province proposed this idea to the ongoing 11th National Committee of the Chinese People’s Political Consultative Conference. This news on the web received thousands of comments supporting the proposal. (If you can read Chinese see how people applause to this idea. If you can’t, just notice the number of supporters.)
