Some time ago I had the opportunity to pay a visit to Farawaystan to study how they treated different educational questions. In the following I am going to tell about my strange experiences. One of the first lessons I attended was in tool science. Here is a section from the textbook:

“3.1 definition. A screwdriver is a metal cylinder, of which one end is flattened and the other end is fixed in a cylinderlike, stiff material, whose surface is not smooth. If the material cylinder is rotated through an angle a, the metal cylinder will rotate through an angle b in the same direction and of the same size as a. The diameter of the metal cylinder is smaller than that of the material cylinder. The material cylinder is often called the handle.
