Film screening of ‘’Chaos’’ (6/4/2016) [fr]
On the 6th of April 2016, the Consulate General of France in Hong Kong and Macau was screening the film "Chaos" directed by professor Etienne Ghys. The event was animated by Prof. Siu Man Keung, honorary professor at the University of Hong Kong.
Held in the impressive Comix Home Base complex in Hong Kong, the evening was set in motion by the Scientific Officer of the Consulate, Julie Metta, who gave a short speech on the theme of the evening as well as presenting us to Professor and Mathematician Siu Man Keung.
Professor Keung obtained his degree in mathematics and physics from the University of Hong Kong and went on to do a PhD in mathematics at the University of Columbia. During his career, he taught mathematics both in Hong Kong and the US.
The film spans nine chapters, lasting thirteen minutes each, focusing on the theory of chaos and the prediction of the future using science. The film drew on the theory of determinism, as well as the notions of the butterfly effect and system dynamics to explain several interesting concepts relative to the theory of chaos.
The evening included a Q&A session lead by the professor. One interesting question asked was on the Theory of the Three Bodies which refers to the difficulty of predicting the final position of three objects. However, it is known that scientists can predict the positions and configurations of stars and comets, so why is it difficult to predict three bodies only?
There’s some food for thought!
