Tensor and coordinate system

[scttzwdrff]

I like that you used just two dimensions. Once the idea is grasped in two dimensions, it's not difficult to imagine it in 3 or more. Thanks.

I am very happy to see the vidoe after you give this Next presentation about tensors. In this presentation I show the relation between tensors and coordinate system and how a tensor changes when coordinate system

[AntoMelta]

I Really Like The Video From Your Tensor and coordinate system

[willamricard]

Your Video Is Very Useful Sharing Next presentation about tensors. In this presentation I show the relation between tensors and coordinate system and how a tensor changes when coordinate system.

after i watched this video, my insight is very open because the video is very good to give information Next presentation about tensors. In this presentation I show the relation between tensors and coordinate system and how a tensor changes when coordinate system

still confuse about what is tensor. a rank 1 tensor has 3 component to represent a arrow in space. It's components have only 1 direction in each axis. So rank 2 tensor has 9 component to represent a arrow in space. it that what tensor is?

[EinsteinInSkirt]

Yes, that the main idea I wanted to pass to the viewers of my presentation.

[RainbowDashXSyndrome]

So it's pretty much Linear algebra combined with trig? that's easy

Thank you very much for the explanation. I´m waiting for your new presentations. Greetings from Spain!.

At 2:06 e of i should be transposed. If you take the Kronecker product as written, you will have a 4x1 matrix not a 2x2.

[supertren]

@gre36789 I think that you are right

[dubistverrueckt]

@gre36789 It's not e of i that should be transposed, but e of j. This, of course, results in the transpose of the resulting matrix shown in the video, but that's as it should be according to the Wikipedia page on the outer product and according to the result you get from Mathematica's OuterProduct[Times, {1,0},{0,1}] command. This way the definition uses straight forward matrix multiplication -- if you transpose e of i and matrix-multiply that with e of j you get the 2x1 column VECTOR {0,1}.

Everythings good and explicit. Any ideas on what this can do on real life application? Thx

[VERGIS92]

@canciones3 without vectors and tensors there's no relativity, without relativity GPS cannot function,

and a whole bunch of science's fields that are explained by vectors.

[EinsteinInSkirt]

@canciones3 Thanks. I am working on new presentations about applications of tensors of order larger than 3, cause these are the most interesting. these tensors have applications in material mechanics and in the theory of relativity.

we are already tensed regarding these concepts..tensed up with this tensors....the notes is no doubt good. but the music?! the background music is kinda fear evoking... tension inducing...oooooo.........plea­se put some pleasant music or no music instead. thankyou
