Discussion Overview

The discussion revolves around the concept of "touching" at the microscopic or quantum level, specifically exploring the forces involved, such as the Pauli Exclusion Principle and Van der Waals forces. Participants seek clarity on the nature of these interactions and the reasons behind them.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant expresses confusion about why we don't "touch" at the microscopic level, referencing the Pauli Exclusion Principle and Van der Waals forces.
  • Another participant suggests that defining "touching" could clarify the discussion and help address the confusion.
  • A third participant explains that touching involves a balance between Van der Waals attraction and repulsion due to the Pauli Exclusion Principle, but notes that understanding the origins of these forces is more complex and may require advanced mathematics.
  • A later reply acknowledges the initial question and indicates that the participant has gained clarity after reviewing the video, expressing a desire to focus on the basics.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definition of "touching," and there remains some confusion about the underlying forces. The discussion reflects both agreement on the existence of these forces and differing levels of understanding regarding their implications.

Contextual Notes

The discussion highlights the complexity of the forces involved in atomic interactions and the varying levels of mathematical understanding among participants. There are unresolved aspects regarding the deeper origins of the forces mentioned.

Who May Find This Useful

This discussion may be useful for individuals interested in quantum mechanics, atomic interactions, and the fundamental principles governing matter at a microscopic level.

I know there's been loads of discussion about this everywhere, but- why don't we touch things at the microscopic(or quantum, whatever) level? I know that it has to do with the Pauli Exclusion Principle, and the Van der Walls force- but- could i just get a plain clear( i know what I'm asking for is near impossible) answer to this? And I've already watched the Sixty Symbols video with Prof. Moriarty. Thanks

Hi Lance.

Why won't you start by defining what you mean by 'touching'. It'll help us see how to address the source of your confusion.

That video is very clear.

We have two competing forces when objects get close together - Van der Waals attraction and repulsion caused by the Pauli Exclusion Principle. When they balance its called touching.

Its very straight forward - don't quite see what your issue is.

The only issue is why do those forces come about in the first place. That however is quite advanced (especially the force from the Pauli Exclusion Principle which took a very great mathematical physicist - Dyson - to work out) requiring a sojourn into advanced mathematics beyond what I suspect your current level is. At the beginner level simply accept they exist.

Thanks
Bill
 
Hey, and thanks. I should've thought twice before posing such a meaningless and somewhat aggressive question. My doubts have been cleared, I've paid more attention to that video. I've got the basics- and I think I'll stick to the basics for now. A big THANKS! :)
