Time as a Derived Physical Quantity Consider a physical system whose state changes and let us call it a Dynamical System. Let a closed Dynamical System, S, whose state be described by ψ-- A mathematical entity we use to describe S (or the state of S). ψ can take on the following...

[What makes you think that the notation "TB" has any meaning until you have defined it? I could guess that it means what's usually denoted by T(G), i.e. the set of all T(x) such that x is in G. Since T is a permutation, this would mean that TB=T(G)=G.] I am not a mathemtician. So, I am...

Well, it is getting deeper into some mathematics that I do not understand and drifting away from the question I am asking. Let me try to put the question with an example to make my question clearer: Suppose f is a mathematical quantity that can take on the "states", or "values", f1...

I can see the NEW REPLY button but not the QUOTE button. And the PREVIEW doesn't seems to work either.

Thanks for your replies. Can you tell me how to make quotes like you do? I can't find the icon that enable me to do so.

Can anyone help with the 2 questions below: 1) Suppose f is a mathematical quantity that can take on the "states", or "values", f1, f2,...fi,...fn., where n can be finite or infinite. So, F is the Set { f1, f2,... fi,.. fn } or F = { f1, f2, fi,... fn } = { all...
