I'm looking for study material on the mathematics of Search and Rescue.<br><br>I've found a couple of websites - one of them, www.sarinfo.bc.ca, is for a company that makes software to perform probability calculations (e.g. given the last place the missing person was seen, the type of terrain, where they were heading, weather conditions, etc. what are the most likely places to start searching? How far could they have gone? etc.) Another site that had some good information is www.islandnet.com/sarbc - it had some mathematical formulae but no info on how to use them.<br><br>For those who don't know (which is probably the majority of you) I run a Saint John Ambulance Family division in Calgary, Canada. We have a number of teenagers involved - they seem quite interested in volunteer work and community service. At least one of them wants to become a doctor, but her grades in math and science are hovering between 50 and 60 percent. My brother's a doctor, and I know there's no way she'll get into medical school if that doesn't improve. <br><br>As a professional mathematician, this causes me great pain. I want to find a way to show these kids that math is not only fun (don't snicker that way, lots of people think sleeping on the ground in subzero temperatures isn't fun either) but practical as well. As they're all quite interested in helping out the community and what our role will be if there's ever a disaster, I think this is something that might appeal to them - as long as I can understand it well enough to 'dumb it down' to high school level.<br><br>I decided to post this to the campfire forum, as it's not directly related to "survival". Any help or pointers would be appreciated.
