i) 有很多的人接受过高等教育;
ii) 很擅长团队合作和协同;
iii) 从历史上来说,中国人很擅长作细致而认真的工作。


First I will explain why, in my opinion, one should make a distinction between technical and scientific progress. One of the main features of scientific inquiries consists in asking Nature simple questions through appropriate experiments.
If we keep this distinction in mind, we will see that in the course of history there have been only few periods marked by real scientific progress. Basically, they were limited to Ancient Greece and to the
period following the so-called scientific revolution in Europe in the late 16th century. In order to illustrate how we can submit questions to Nature, I will perform an experiment involving a spherical pendulum (i.e. a pendulum whose mass remains on the surface of a sphere). When done with high accuracy this experiment allows us to measure the angular velocity of the Earth. In fact, I should rather say, the angular velocities for the Earth has indeed several movements of rotation, two of which are illustrated below.
Earth-Sun system: T=365 days Rotation of the Earth’s axis: T=20,000 years This is part of an ongoing research which was started by Prof. Yang of the “Beijing University of Post and Telecommunication” and about which I would be glad to get your advice.
In a general way, Nature will provide clear answers to well designed experiments which in turn will give us a better insight into the phenomenon under investigation. On the contrary, if the experiments are not well designed nothing clear will emerge. In this respect an important factor is the level of “noise” respective to the signal-level. If the noise is too important (as is so often the case for social phenomena) no clear law will emerge.
China has three major assets for scientific research.
i) A highly educated population.
ii) A wonderful aptitude for teamwork, cooperation and synergy.
iii) A long tradition for meticulous and careful work.
The last two factors are especially important for experimental research. However, the present organization of scientific research in western countries is based on principles which go in the opposite direction, namely individualism and competition instead of cooperation on the one-hand and predom-inance of theory over experimental work on the other hand. That is why I have the feeling that by accepting to follow the rules of the “game” set by Western countries, China may not be able to take full advantage of its own assets.
Perhaps we can discuss this point further at the end of my lecture. I must confess that I would be curious to hear your opinion.
