Discussion Overview

The discussion revolves around understanding tensors, with participants seeking explanations and resources for learning about them. The scope includes theoretical understanding and recommendations for online materials.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant requests an explanation of tensors or recommendations for websites that explain them.
  • Another participant shares a link to a website they find to be a simple introduction to tensor analysis, noting that comprehension may depend on one's background in linear algebra.
  • A participant suggests using the search function in the subforum to find previous discussions on the question "what is a tensor?" which often appears.
  • Another participant lists several websites they find useful for learning about tensors, particularly for those interested in physics, and cautions that different sources may use varying notations.
  • One of the shared resources is highlighted as a recommendation from another discussion, indicating a connection to previous conversations on the topic.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a single explanation or resource for understanding tensors, as multiple viewpoints and resources are presented.

Contextual Notes

Participants note the potential for confusion due to differing notations across various resources, which may affect understanding.

could someone please explain tensors to me or at least tell of website that explaines them

Quick intro to tensor analysis-- probably the simplest I've found.
It's very easy to comprehend, it just depends on your background. (Especially with linear algebra, obviously)
Enjoy.
 
search this subforum (there is a search function), the question 'what is a tensor?' comes up regularly here, you will find some nice explanations
 
i am also trying to learn it

there are some websites that i find useful (especially if you are also interested inphysics):

http://pancake.uchicago.edu/~carroll/notes/

http://people.hofstra.edu/faculty/Stefan_Waner/diff_geom/tc.html

http://www.cs.elte.hu/geometry/csikos/dif/dif.html

http://vishnu.mth.uct.ac.za/omei/gr/info.html


http://ocw.mit.edu/OcwWeb/Physics/8-962Spring2002/LectureNotes/index.htm --->>(robphy's recommendation in another discussion)

Also i have to warn you about notation some of them may not be agree in notation so it is better to choose one of them
