Quotation from Dialogues Concerning Two New Sciences (Second to Fourth Days) by Galileo Galilei
“it is a very remarkable thing that, among the infinite variety of solids which are similar one to another, there are no two of which the forces [momenti], and the resistances of these solids are related in the same ratio”
Dialogues Concerning Two New Sciences (Second to Fourth Days), Second Day, discussion following Proposition VI, trans. Henry Crew and Alfonso de Salvio (1914)
Salviati states the scaling principle that a large column breaks where a small one of the same shape does not, which he says a casual observation first led him to investigate.
