Abstract
APART from the extreme criterion of bone fracture, there is no definitive measurement of bone adequacy in terms of strength in relation to function. Comparison of bone mineral is usually made on the basis of age1 or sex2 without regard to the size or the physical status of the individual. This is in spite of Galileo's observation that the weight of a body is a function of the cube of its diameter whereas the strength of a bone is a function of the square of its diameter3. Galileo also conceived that a constant sized bone would support more weight if it were made of a stronger material, but did not seem to be aware that bones are subject to change in density. This is rather surprising as he discussed at some length the density of various substances. We now know that bone density varies and that the strength of both trabecular4 and cortical bone5 increases with density.
