@Chestermiller post in this thread helped me a lot: https://www.physicsforums.com/threa...roach-think-of-a-problem.712959/#post-4521833 Do you have a different strategy to develop a mathematical model of a physical system?

Thank You

I think i did not use the right words. I am from Brasil. Sorry for the bad english. What I want to understand is how someone understand physical systems mathematically.

which part you did not understand?

I want to know how can I begin to exercise the representation of a phenomenon in a mathematical model.

Sorry for the meaningful question. You really helped me out. :D

Thank You

I understand that we can always add 1 more item to a list. What I can't understand is how does someone calculate the variation of something infinity.

Cool. I've never heard about it before.

Thank You

Thank You

How does universe expansion work? I thought that the universe was infinite and the celestial corps were getting further distance from each other. If the universe is infinite, how does someone calculate something when infinity is getting bigger? From a reference point? Is the rate of expansion...

Hello, Guys. My name is Eduardo and I'm a physics student. I hope we can share a lot of information with each other! :)
