Discussion Overview

The discussion centers on the existence of exact three-fold symmetry in physics, exploring theoretical and conceptual examples, as well as constraints that may prevent such symmetry from being realized. Participants consider various contexts, including particle physics and spatial symmetries.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant notes that an isolated electron and positron exhibit an exact two-fold symmetry and questions the existence of truly triplicate symmetry in physics.
  • Another participant suggests baryons composed of three identical quarks as a potential example of three-fold symmetry.
  • A different participant points out that the electron/positron symmetry is an exact anti-symmetry, comparing it to the anti-symmetry between electric and magnetic fields in electromagnetism, and emphasizes the importance of sign changes in wave equations.
  • Another contribution raises the idea of color charges of quarks as a possible instance of three-fold symmetry.
  • One participant proposes the concept of cyclic rotation of the x, y, and z axes in space as a form of three-fold symmetry.

Areas of Agreement / Disagreement

Participants express differing views on the existence and examples of three-fold symmetry, with no consensus reached on whether such symmetry exists or what forms it might take.

Contextual Notes

Some claims rely on specific definitions of symmetry and may depend on the context of particle interactions or spatial considerations. The discussion includes various interpretations and assumptions that remain unresolved.

An isolated electron and positron depict an exact two-fold symmetry. Are there any examples in physics of a truly triplicate symmetry? If not, what constraints are there that prevent it?

How about that for baryons composed of three identical quarks?
 
To be very picky, the electron/positron symmetry is an exact anti-symmetry like the anti-symmetry between E and B in EM. The spinor wave equation pair have a change of sign, or they would be symmetrical.

I've been told I'm a pedant already.
 
How about the color charges of quarks?
 
cyclic rotation of x y and z axis in space ?
