"The commonsense descriptions are vague and couched in words rather than in numbers, and do not take account of many possible sources of error. Common-sense generalizations are vague, intuitive, and often contradictory. It is only necessary to compare the common-sense generalization 'objects tend to fall to the ground when left unsupported'  with the actual formula giving the behaviour of falling bodies as 1/2 gt² to realize the tremendous difference between common-sense concepts and explanations and scientific laws and formulae."
