What's a Tensor?

I'd be scared if my Z component was equal to Octopus! D: (7:38)

Why didn't somebody tell me this before??????

[mrtamborineman10]

very nice job! thanks

To see a visual representation of what I am trying to say with regard to "pages" of matrices please look at the Levi-Cita symbol on wikipedia and there will be a diagram on the right side of the image I wanted to post here but it came up with an error.

Thanks for the video.

I was curious cause you did not mention it but isn't a Rank 2 tensor also a matrix of vectors (square matrix, is better)....so that 3X3 matrix could represent a similar concept. I am not sure if I said that right but to continue on that line of thought, the Rank 3 Tensor would be like a 3X3 matrix with 3 "pages" to it which would make it 3X3X3. I hope you understand what I mean and was wondering if this idea of 3-dimension matrices are used (probably replace by tensors in modern math though)...

Sir, thanks a lot! You have all my respect!

[iatibavinsky]

Your classes are probably the first ones to fill up every semester during registration at the school you teach. Thank you so much.

[sharrajesh465]

same as brilliant as your description of maxwell equations in the other podcast by you

[DasAbhishek1503]

Classic video ... cleared my doubts regarding the concept of tensor



[AristosKisai]

Very good! Thank you for taking the time to explain!

[vebazzo21]

Thank you very much, Mr. Fleisch!

[clbgeballe]

hey youre missing a nerf bullet on the rank 3 visualization

[NortheastManic]

Absolutely one of the most helpful videos about conceptualizing tensors I've seen. Thank you so much!

[Ferrari312pb]

Thanks Dan.

I have your book on Maxwell's equations on order and hope it is as lucid as this demonstration !

[rohitarora1981]

awesome!

[Epilogue02]

Excellent video, thank you for uploading!

[KulautuvosMX]

It's obvious that you put a lot of effort into this video. It was great, thank you very much.

[yoududeuser]

That was brilliant thanks. It's this kind of thing that is the "missing link" at the start of every new mathematical topic.

[HarishS88]

Great..

[ilovephysics1122]

great and helpful video

[knvk2008]

great video ..

[Lapogc]

Thank you for such a lucid explanation of Vectors and Tensors.

Looking forward to reading your book.

I really liked the visual aids -- the visualization of 2nd and 3rd rank tensors were particularly instructive.

Excellent presentation!
