I had the pleasure of listening to Oxford University mathematics professor Marcus du Sautoy talk about Symmetry this past Monday at the University of Oslo. The lecture was entitled Symmetry: Reality’s Riddle. The event was co-sponsored by the New Science Library (Det nye realfagsbiblioteket) and the Freedom of Expression foundation (Fritt Ord). The library building (Vilhelm Bjerknes house) will undergo extensive renovations starting in 2011, supported in part by the Freedom of Expression foundation. When the building renovations are finished in 2012, the library will be used as a center for seminars and debates about science and its role in society. Professor du Sautoy was invited to give a talk because he is also a professor of Public Understanding of Science at Oxford, and the library is interested in focusing on this aspect for the future. After listening to du Sautoy talk on Monday, I can understand why. Here is a man who can talk about mathematics in a dynamic way, in a way that captivates an audience while at the same time educating them. This is no mean feat. He is smart, clever, good at what he does, but more importantly, he can talk to people outside his profession and get them interested in his work and in mathematics. He has done this by writing best-selling books, hosting TV and radio programs in Britain, holding lectures internationally and so forth.
During his lecture on Monday, he spent a good deal of time talking about the symmetry found in the mosaic tiles of the Alhambra, a building in Granada Spain designed by Moorish architects. He also talked about M.C. Escher, whose art fascinated many of us when we were younger. He was the artist who drew staircases in space that merged into other staircases and it was impossible to know where one started and the other ended http://www.mcescher.com/Gallery/back-bmp/LW389.jpg. What I didn’t know was that Escher has done an entire gallery of symmetry drawings as well http://www.mcescher.com/Gallery/gallery-symmetry.htm, and that he was fascinated by the Alhambra. So I can thank Professor du Sautoy for this new bit of knowledge. Overall it was a very interesting lecture, and it struck me while he was talking that he did not have to hold an actual talk about the ‘public understanding of science/mathematics’ in order to impart an understanding of his field. His subject was complex, and this was clear to the audience, but his presentation was not obscure or unintelligible. His talk imparted a general understanding of the complex mathematics underlying symmetry (the number riddles involved—hence the name of the lecture, Symmetry: Reality’s Riddle) in a way that was fun, exciting and challenging. The other thing that struck me was that the audience had a lot of questions for him after his lecture, and that is the sign of a good lecture. People were not afraid to ask questions or to share their own experiences and thoughts, and that simply means that he inspired his audience rather than driving them away. I found myself remembering my calculus professor from my freshman year in college. He was such a poor teacher, even though he probably had a good grasp of his subject. He simply could not communicate his knowledge to his students, and the majority of students failed his class. That did not seem to matter to him. I stuck it out for the full year, but never took a math class again after that. I hit the wall somewhere around ‘integration by partial fractions’ which he could not intelligibly explain to us to save his life. But in high school, I really enjoyed all my math classes, and that was due in no small part to Ms. Moloney, our math teacher, who could explain what needed to be explained in an understandable and fun way. That made all the difference. Good teachers who know how to communicate their knowledge and who do so in interesting and motivating ways are the key to attracting students into math and science professions. Professor du Sautoy is one of them.
