Pretty interesting. Mr. Xu was very witty. But he does indeed seem to have a bit of a folk-science air about him. His “integrated waterway” sounds far too mystical; to fantasize about solving “all environmental problems” through such a technology, even if Mr. Xu insists that this is not technology but science, is still a bit too naive. As for the “fundamental error of Einstein,” that was the weak point of Mr. Xu’s lecture this time. Of course, science must oppose blind faith in authority, but scientific masters are after all masters—how could they be so easily refuted? Wave-particle duality is after all persuasive; not to mention photons and light waves, de Broglie’s theory of matter waves is still very credible. If one says that the propagation of light cannot be regarded as displacement, then no object can be said to undergo displacement either. Relativity solved the problem of Mercury’s perihelion precession, and the predictions of general relativity have been verified. Of course that is not to say errors are impossible in the future, but to say that it is simply wrong because it is wrong is really a bit too childish.
Teacher Liu Huajie did quite a good job as moderator; the choice of topics and the transitions between them were both fairly appropriate, and the event proceeded rather smoothly. If Tian Song were put in charge, and once he got serious about it, I’m afraid it would blow up~~
