+ | However, in our environment the spatial extension of particles in crucial. | ||
+ | Physical objects always keep a minimum distance due to their spatial extension. | ||
+ | When they had zero extension, | ||
+ | one could neither blow up water droplets by impact with a laser ([[# | ||

+ | Even giving spin to a ball only works due to the distance between the surface of the racket | ||
+ | and the center of the ball. | ||
+ | |||
+ | At the end of this chapter we will be able to discuss the evolution of balls with spin, | ||
+ | and their reflections from flat surfaces. | ||
+ | Why is spin of so much importance in table tennis? | ||
