History of Chaos Theory and Nonlinear Dynamics

Hello:
There is a student at my university who is interested in writing an
honor's thesis on the history of chaos theory and its impact science.
She is looking for books and articles to begin her research. I have
recommended Gleick's Chaos to her as a starting point. I have a few
other books in mind, but I was wondering if anyone on this forum has
any suggestions on good articles/books on the history and impact of
chaos theory? Please note that this student is not a science or math
major. Hence, she would want to steer away from materials with heavy
amounts of mathematics.

Thanks for your suggestions.
