I Mathematical model of a phenomenon

  1. Oct 1, 2016 #1
    I wanna know how can I begin to exercise the representation of a phenomenon in a mathematical model.

    You could start by giving us a hint. What are you talking about?

    First of all, you probably need physical principles.

    To exercise a model one way is to feed it data and see if the model behaves the same as the real world.

    which part you did not understand?

    Wadda-ya-mean by the term "exercise the representation of a phenomenon in a mathematical model." As an engineering professional who has had 35 years of industrial experience developing and applying mathematical models of physical systems, I have never heard this term before.

    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.

    Thank you very much for clarifying this. Yes, your previous post was a bit aggressive to English-only speakers. It's a classic intellectual retort to say "which word did you not understand". I've used it at times, but never at the PF. :smile:

    I don't think it is about using the right or wrong words, I just think you didn't use enough of them. What physical system? What part of it are you wanting to model? For what purpose? For example, today, I modeled the energy use of a fan -- will that be helpful to you...?

    @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?
