Math comes in handy for answering questions about a variety of topics, from calculating the cost-effectiveness of fuel sources and determining the best regions to build high-speed rail to predicting the spread of disease and assessing roller coasters on the basis of their "thrill" factor. How does math do all that? That is the topic of a free handbook published by the Society for Industrial and Applied Mathematics (SIAM): "Math Modeling: Getting Started and Getting Solutions."
You can view or download the PDF for free, or order a print copy, which is available for $15 to cover the cost of printing and mailing. Please contact SIAM Customer Service at +1-215-382-9800 or toll-free 800-447-SIAM (US and Canada) to order a print copy of the handbook.
