摘要:

A simplification of the problem concerning the visual appearance of a rapidly moving sphere is presented. The approach brings out the uncontracted appearance of the sphere and its apparent rotation through the angle ϑ=sin−1(v/c) when viewed at an angle perpendicular to its motion. The problem is shown to be sufficiently simple to be a homework assignment in an undergraduate relativity course.
