"It is true that nature can sometimes involve some strange designs, but to evolve to have a brain ten times the size we needed would seem very odd, when its large dimensions are so costly to our survival, leading on occasion to obstructed labour and the death of a mother during childbirth...

In classical mechanics the laws are initially formulated for point particles in which the dimensions, shapes, and other intrinsic properties of bodies are ignored. Thus in the first approximation even objects as large as Earth and the Sun are treated as pointlike—e.g., in calculating planetary...
