List of online resources

The following URLs are taken from the book "Real Life Math: Everyday use of mathematical concepts" by Evan M. Glazer and John W. McConnell (2002). It is a book on real-life applications of math sorted in alphabetical order. Below are the links I have selected from the book after checking authenticity. Some links differ from the book as they were moved. Do take time to look through some of the topics, especially complex numbers where both teachers and students have a hard time coming up with examples of complex numbers in action. The website by British Columbia Institute of technology provides many interesting mathematical applications to technology.
