Science Quotes by Arturo Rosenblueth (2 quotes)
No substantial part of the universe is so simple that it can be grasped and controlled without abstraction. Abstraction consists in replacing the part of the universe under consideration by a model of similar but simpler structure. Models, formal and intellectual on the one hand, or material on the other, are thus a central necessity of scientific procedure.
— Arturo Rosenblueth
As coauthor with Norbert Wiener in 'The Role of Models in Science', Philosophy of Science (Oct 1945), 12, No. 4, 316.
The best material model of a cat is another, or preferably the same, cat.
— Arturo Rosenblueth
As coauthor with Norbert Wiener, in 'The Role of Models in Science', Philosophy of Science (Oct 1945), 12, 320.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
