Here we will develop a simple, basic rolling cylinder with internal structures that you can adapt to look into the physics of this deceptively simple-appearing motion.

In this chapter we talk about ice and snow and create models of some of the more intriguing geometries that frozen water can create.

Learning Grasps in a Synergy-based FrameworkWe all toss around words like likely and impossible, but we rarely try to quantify what they mean. That job is left to experts in probability and statistics. Often our perception of how likely something is has very little to do with how likely it really is, which is good news for people who run state lotteries. Probability
