Choose any modern or ancient engineering marvel (i.e. The Hoover Dam or The Great Pyramids of Egypt) of your own interest. There are countless options to choose from if you do a Google search. Also, there are many great engineering films on Netflix. Type at least a two page paper, single spaced, font size 12, describing where the engineering marvel is, what purpose it serves, what challenges were faced and what building materials were used in its construction, what environmental impact building the structure had and continues to have, and what mathematical ideas were applied in its construction. The more math ideas you specify the better. Include a picture and global map indicating the country and city of the marvel.  Include any other information that you feel the reader would find interesting.
