Dynamical chaos in a simple model of a knuckleball
作者:
Highlights:
• Simplified models of a knuckleball using empirical data for the aerodynamic forces yield dynamical chaos.
• Uncertainties of as little as 0.01% in initial orientation and angular velocity can yield movement of as much as 40 cm at home plate.
• Supports the long conjectured idea that the knuckleball works because of dynamical chaos.
