Subject: Re: Proportions and ratios

Hi Danielle, First, when I typed "history of proportions and ratios" into the google search engine [http://www.google.com], I got topics such as * managing your business successfully by means of proportions, * proportions used in chemistry, * scale models (pages of these sites), from doll houses to architectural design and landscape architecture, * Mendel used proportions in biology, * artists use proportions, and * Greek ideal human proportions. I even found a religious reference about deities using proportions to create the universe. In addition, I usually introduce proportions in my classes like this: There is a West Wing TV episode about "proportional response" where our leaders are discussing how to respond to an attack of terrorism. As far as history of proportions in math, the following site should prove helpful: http://www-groups.dcs.st-and.ac.uk/~history/Search/historysearch.cgi It contains a wealth of leads in whatever direction you want to go with proportions. In my classes, we make scale models in two sizes and figure out the ratios of sides, areas and volumes. Hope this helps. -Alice, for the T2T service Thanks for visiting our on-line community.
