Intuition for Parallel Transport

Click For Summary

Discussion Overview

The discussion revolves around the concept of parallel transport, particularly in the context of surfaces. Participants explore the intuition behind maintaining parallelism while navigating along a surface.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant expresses confusion about how parallel transport can occur on a surface, questioning the feasibility of maintaining parallelism.
  • Another participant clarifies that "parallel" refers to being parallel to the surface and also to itself as much as possible during transport.
  • A later reply suggests that the effort to maintain parallelism is acknowledged, but ultimately, the result may lead to significant deviation from parallelism.
  • Another participant provides an example involving navigation along a meridian, indicating that despite efforts to remain parallel, unexpected outcomes can occur, such as the orientation of one's head pointing towards a distant star.

Areas of Agreement / Disagreement

Participants do not reach a consensus; instead, they express varying levels of understanding and interpretation of parallel transport, with some acknowledging the challenges involved.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about parallelism and the specific definitions of terms used, which may affect the clarity of the concept being discussed.

Hi All,

I am an idiot but I don't understand the parallel transport:

Parallel transport should be in surface right? How to keep parallel and still be in surface?
 
Physics news on Phys.org
Parallel here means, first of all: parallel to the surface. Once this is kept in mind, then the next demand is: "be parralel to itself as much as you can".
 
ah! I got it now.
That TRY to make parallel was sufficient.
You try to make parallel with preceeding one as much as possible and in the end it gets hugely NOT PARALLEL.

Thanks again.
 
Well, go straight along the the meridian. You follow the advice and, after a while, you find your head pointing at the Pole star. Surprise? Well, you did your best.
