Dr. Nancy Nicholson was a wonderful educator with a sharp and intelligent mind and an advocate for the horse. She was fascinated by equine and rider biomechanics and dedicated to understanding and sharing her scientific discoveries as well as her personal growth in biomechanics topics. Nancy was never one to settle on a final answer, there was always more to investigate. Her book is ground breaking, and a work in progress. Her passing is a huge loss to the equestrian community as she was never one to stop, to give up on such a complicated and fascinating study. If she were able, there would be many more editions and edits. I am grateful that this book begins a deep dive on the subject of biomechanics.
