Engineers of Mines by training, we discovered the wonderful sport of ultimate in 2013. Since our initiation, we have multiplied our international experiences. Always in a quest to understand the sport on a fundamental level, our approach was based on our scientific training and a background of high-level athletes. We relied on a background of diverse backgrounds (piano, gymnastics, judo, and chess) that we coupled with experience in the field. This way of thinking about the sport led us to write this book, a testimony of this unique vision.
