Portal:Mathematics

 Welcome to the Mathematics Portal Mathematics is a language - many mathematicians have described the process of mathematics as art and poetry. Bertrand Russell once wrote, “Mathematics possesses not only truth but supreme beauty, a beauty cold and austere, like that of sculpture, sublimely pure and capable of a stern perfection, such as only the greatest art can show.” Other mathematicians and scientists have often written about the unreasonable effectiveness of mathematics in explaining the world around. Notwithstanding the poetry and the beauty, a functional knowledge of mathematics and computing is an essential skill for transacting in society. However, to appreciate the poetry of this language or to transact, one must learn the grammar and acquire the vocabulary. And school mathematics is largely about acquiring the skills to communicate and develop the love for the language. This portal is for students and teachers to engage with this language and build those skills.

 Classroom resources This section will feature resources for classroom teaching including online, digital and other hands-on activities. We will begin with Geometry - triangles and will be adding resources every week.

 Interesting read In this very interesting article, "engineer-mathematician" Dr Barbara Oakley talked about how mastering procedural fluency, combined with language fluency helped her master mathematics, even when she began learning advanced math at the age of 26! Barbara Oakley is a professor of engineering at Oakland University, Rochester, Michigan, and the author of, most recently, A Mind for Numbers: How to Excel at Math and Science (Even If  You Flunked Algebra). She is also co-instructor, with Terrence Sejnowski, the Francis Crick Professor at the Salk Institute, of one of the world’s largest online courses, “Learning How to Learn,” with Coursera.

 Interesting news If mathematics is a language, then how does it seem to describe all the observed things in the universe from helical DNA structures to black holes. Mathematicians and scientists have talked about the unreasonable effectiveness of mathematics. So is mathematics inherent in the universe or is it part of the way the human brain is wired? This question is being studied and some recent research can be accessed here.
