“Any model you build is only going to be good for answering the questions you asked,” Christina Edholm, PhD, of Scripps College. That's a real quote from the article on mathematical models , a topic which usually I'd avoid but it's pop-science dive so it wouldn't hurt, I thought. A very interesting article indeed. That's why I like to read around, you never know what can inspire you. Something that might not make any sense to anyone else, except you and me. “Models thus need to be a living tool ” Nina Fefferman, PhD, an evolutionary biologist at the University of Tennessee.
