Copernicus, Einsetin, Galileo, Newton, and Aristotle? How did the differ in their ideas and contributions to physics?

Is this a homework question?

Is the answer - One of them was left-handed.

They were all born on different days?

They're just too different to mention their differences!
If it were only Galileo and Newton, there could be an answer.

yes indeed, the answers can vary because of the divergence in the question.
I am not sure about everyone, but:
1) Aristotle was the 1st to propose a "law" of mechanics, which was equivalent to what people used to see and understand in those days. That you act a force and the object moves, so the idea was something like $F=a v$ with a a proportional constant and v the velocity.
The interesting part in that law is that it holds for motion in very thick liquids (for example the motion of a body in honey).
The thing with ancient "scientists" or better philosophers is that they didn't really use mathematics in the way they were later come in use. For example there was no differential equation formalism, and most of their ideas were based either on their philosophies or on their observations/phenomenolgy (I push the door,it opens- I push it stronger it opens faster)

I like ChrisVer's approach to answering the OP's question. Maybe we can state the basic differences between general principles used by scientists in different eras.

This is far too broad. Locked.
