Computer models can hold large amounts of variables to communicate complex answers to scientific inquiries. Was Newton then wrong? This is not just a misconception among students, but among the general public as well. A scientific model is a proposed explanation for some phenomenon. 1.2 The Scientific Methods - Physics | OpenStax. They are useful as educational tools and mainly show the intricate workings of various phenomena or abstract concepts. Points represent the system states in these (usually Euclidean) spaces.
