When Balls Collide

A scientific look at the skill of juggling. For the juggler who's interested in science or the scientist who's interested in juggling this is a comprehensive examination by two experts in the field. We look at the pros and cons of different juggling patterns and analyze various constraints jugglers face including: hand speed timing throwing errors and the spatial constraints of objects in the air. We make some conclusions about optimal patterns what constitutes good form how jugglers avoid collisions and the human limits of juggling. We also look at the many ways jugglers change the constraints to make it more interesting. Other topics in the book include: juggling definitions different props historical juggling juggling records the physics of thrown objects Shannon's juggling theorem and other useful equations juggling instruction siteswap notation and training advice.
