Ohio Forensic Guide

I’m a Forensic Science major and I have a honor’s presentaion coming up about Newton’s Law of Cooling and its application in Forensics. I was wondering if anyone knew where I could find good, in-depth, reliable, information about its history and applications. I’ve already “googled” it and haven’t found anything useful. Any suggestions would be helpful because I don’t have alot of time to wonder around aimlessly on the internet. I would really appreciate it. Thanks!
