I am working on a PhD degree in the field of computational chemistry. In particular, I am interested in applying existing theoretical and computational methodologies to develop novel and efficient approaches towards studying organic small-molecule catalysts and predicting their chemical properties. Since I am originally a physical chemist by profession, this book has taught me something I've always been lacking: The ability to think to think like a mathematician. Sometimes when a certain concept in science is muddled with ambiguity, you have to distill it down to basic building blocks of pure logic and reason. I've learned a lot from this book and I would definitely recommend it to anyone who is willing to sharpen their mathematical skills.
