Order parameter, correlation function and length

Click For Summary

Discussion Overview

The discussion revolves around the relationship between order parameters, correlation functions, and correlation lengths in the context of physics. Participants seek clarification and intuitive explanations regarding these concepts.

Discussion Character

  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant expresses confusion about the relationship between order parameters, correlation functions, and correlation lengths, requesting an intuitive explanation.
  • Another participant emphasizes the need for a deeper understanding and encourages others to engage in the discussion.
  • A separate participant introduces a different topic, asking about Newton's second law and the reason objects fall down rather than up, suggesting a connection between understanding physical principles and the initial question.
  • A response to the second question highlights the importance of established physical principles, suggesting that understanding these principles is crucial for addressing the questions posed.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants have varying levels of understanding and focus on different questions, with some engaging with the original topic and others shifting to a different concept.

Contextual Notes

Participants have not yet defined specific assumptions or provided detailed explanations regarding the initial concepts of order parameters and correlation functions, leaving the discussion open-ended.

Hello people,

I don't understand the relation between those concepts, I tried to read what's written in wikipedia about them but no use.

Can someone please elaborate more about the relation between them in some intuitive manner?

Thank you :)

Come on physicists! show me your powers :)! Please, I really need to understand this :'(.
 
Very well, I have an easier question though, since there is not a single comment!

Here is the question...

What's Newton's second law? and why do things fall down not up?

Think hard guys! it's not that easy :P
 
why don't things fall up? if you will answer on it you will answer on your second question...

You should start to believe in any general physical principles which were established by experimental way (or theoretical if it was proof by experiments or predicted of course)... and if you doubt one's own eyes you should sleep more...Denis
