SUMMARY

The forum discussion centers on the concept of touch at macro and nano scales, emphasizing that touch is fundamentally an interaction of forces rather than a direct contact. Participants express discomfort with simplistic explanations, particularly the notion that "electrons repel each other." The conversation highlights the complexity of defining touch, questioning whether electrons, as point particles or vibrating strings, can truly "touch." Ultimately, the consensus is that touch is a nuanced interaction rather than a straightforward physical connection.

PREREQUISITES
  • Understanding of basic physics concepts, particularly electromagnetism.
  • Familiarity with particle physics, including the nature of electrons.
  • Knowledge of macro vs. nano scale interactions.
  • Ability to interpret scientific explanations and theories.
NEXT STEPS
  • Research the principles of electromagnetism and electron behavior.
  • Explore particle physics, focusing on the characteristics of point particles and string theory.
  • Study the concept of force interactions at both macro and nano scales.
  • Examine scientific literature on the philosophy of touch and perception in physics.
USEFUL FOR

Students and enthusiasts in physics, educators explaining complex scientific concepts, and anyone interested in the philosophical implications of physical interactions.

We have had this question popping up over and over again. We may need to add this to our FAQ.

Yes, please do.
 
I always find that explanation wonky, just don't feel comfortable with statements like "The electrons on my behind repel the electrons on the chair". Anyone else feel the same.

No, I'm not concerned about the electrons in your behind :smile:
 
Pretty sure you know what I mean. Oh okay, watched the rest of the video, the irksome feeling went away.

Yes, but I couldn't resist.
 
I heard there are a lot of vacancies for electrons, well the ones that work in the "behind" against chair region...

"""I always find that explanation wonky, just don't feel comfortable with statements like "The electrons on my behind repel the electrons on the chair".""""
i might bet that the electrons feel similarly.. :D
 
Sure, in an everyday macro setting you can say we "touch" things. But if you really want to get deep into it, what exactly is touch? Even if you could get electrons to "touch" each other, what exactly does that mean? For all we know an electron is a point particle...and what happens when you touch two point particles? Well, they'd be on top of each other. Or maybe it's a vibrating string...so then what, the strings touch?

Either way, we have to be satisfied with the idea that touch, whether on a macro or nano scale, is just interaction of forces.

This is just my layman's interpretation of it, please someone straighten me out if it's way off.
