How to understand differential geometry

Click For Summary

Discussion Overview

The discussion revolves around understanding differential geometry, particularly its abstract nature and the challenges faced by learners. Participants seek methods and resources for grasping the concepts, as well as the relevance of differential geometry to physics.

Discussion Character

  • Exploratory, Homework-related, Conceptual clarification

Main Points Raised

  • One participant expresses difficulty in understanding differential geometry, seeking guidance and methods for learning.
  • Another suggests starting with the differential geometry of curves and surfaces and recommends specific textbooks.
  • A participant questions the necessity of differential geometry for physics, indicating a struggle with conceptual understanding.
  • One reply suggests that a lack of geometrical intuition for derivatives may contribute to difficulties, recommending additional reading materials to build foundational knowledge.
  • A participant acknowledges their struggle with the subject and reflects on their foundational knowledge as insufficient.
  • Another participant inquires about the works of David Henderson, implying they may be relevant resources.

Areas of Agreement / Disagreement

Participants generally agree on the challenges of understanding differential geometry and the need for foundational knowledge, but there are differing opinions on the necessity of the subject for physics and the best resources to use.

Contextual Notes

Some participants mention specific books and resources, but there is no consensus on a singular approach to learning differential geometry or its relevance to physics. The discussion reflects varying levels of understanding and different interpretations of foundational concepts.

Who May Find This Useful

Individuals interested in learning differential geometry, particularly those struggling with its abstract concepts or seeking resources for foundational knowledge.

the differential geometry is so abstract to understand. All are terms and theorem. How to understand it? can someone give me some method and guidance to learn it. HELP!
 
Physics news on Phys.org
Yes. Learn the differential geometry of curves and surfaces first!

Some books:

Differential Geometry - Wolfgang Kühnel

Elementary Differential Geometry - Barrett O'Neill

Elementary Differential Geometry - Andrew Pressley
 
is differential geometry a necessary tool for physics? I find my space conceptual is bad ><
It do not like calculus gt method to refer and practise. All are conceptual derivative!
 
I won't pretend I understood your last post but if you still find elementary differential geometry of curves and surfaces is too abstract, it might be because you do not have the correct geometrical interpretation/intuition for derivatives of maps R^n-->R^m. In this case, you need to read something like

Elementary Classical Analysis - Marsden & Hoffman

Calculus on Manifolds - Spivak
 
Thanks. This is much more easy to understand. Seems like my basis is not strong enough to proceed to diff geo...
 
have you looked at the books of david henderson?
