Here i am who cant understand what a vector is

Love the explanation. Thanks for the video. But shouldn't the arrow representation (starting at, say, 9:00) of A_yz be the other way around (laying arrow left and standing arrow right)? Actually: in the x-row you chose top -bottom visualisation (x-arrow always bottom), but for the y- and z-row you have chosen a left to right visualisation.

I thought it was about tensors not about vectors 5:58 already over 5 minutes !

12 years ago , there was a tensor consept amazing 🤩

Thank you for this explanation! ❤

❤️❤️

Thank you so much for taking the time to do this beautiful explanation. These are times that make me glad that I chose the field I did. Tensors are indeed facts of the universe.

Hope you meet you in person so that I can shake your hand!

Thank You so much

Dan this is fantastic ! Thank you ! I love this 3D explanation.. All the best to you

Thank YOU for your time Sir

Best explanation, thanks for making this so clear and easy to remember, subscribed.

amazing

ty mr. fleisch! i very much appreciate your time and willingness to explain this. Good man!

Am I the only one who heard a "Oh Yeah!" around 0:42 . Great explanation too thanks for the lesson.

I am in class 10th and this video is so incredible that it even made it easy for me these type of teachers are the ones who truly love physics

0:28 Today you'll learn how to defend yourself against a Tensor that attacks you with a pointed stick.

I found this video a very good complimentary: czcams.com/video/K7f2pCQ3p3U/video.html

No one can see nothing. Wrong camera placement. You should have put camera behind the light.

Take a bow 🙇‍♀️

That is a very very good explanation

1:01 - force of gravity smh

Love the Monty Python poinTED stick reference!

Outstanding. There are teachers, Teachers and TEACHERS; and TEACHERS like this are all too rare. It’s a special treat to take a masterclass from someone so thoroughly across the material, that they have the ability to simplify the complex. Thank you.

Was doing a ml course and wanted to know about tensors, henceforth clicked on this, worth every second of my time

This is the best explanation of what a tensor is that has ever been made. An absolute marvel, thank you very much!

Thank you so much

Sir, I am not a student anymore, still just watched the entire video, thank you! thank you for doing this for all students.....this is probably the best explanation of tensors on CZcams! I wish I found this video in highschool 😅

what an amazing teacher! Thanks!

Thanks Dan. Thanks for putting in the work to help folks understand the visualization of tensors. Every instructor of such should have to use this video/ If you were to expand on your presentation to upper level physics students, you might include time and the use of the word metrics.

Thank YOU very much for your time to create this terrific explanation of tensors.

Thank you sir.

Nice group

Good piece of wisdom that young man needs to be advised.

Too much time spent on explaining vector concept, should make another video just for vector. You can just watch the example of using a single vector representating the area and then jump to watch the conclusion.

Thank you!

I've been working on a video to explain the tensor as it applies to mechanics (static stress) since 2018. I have yet to unify the math and bring it home in my brain. I "get" how it works, but I remain skeptical about the tensor concept...not that it does not work, but rather that I have not seen a clear explanation of what exactly is going on behind the math. What is impressive about Dan's video is how well it ages: he uses no animations, yet manages to explain in very clear terms many aspects of tensors in a practical sense.

Thank you sir for one of the best explanation.

Very well explained!

the best explanation ever!!!

I'd always thought of Spacetime as being a scalar. Why? Because space is described in terms of distance and time is described in terms of duration. To me, distance and (perhaps) time have magnitude only... and would seem to be scalar properties. But if an area can be thought of as a Vector (as mentioned early in the video) then could you think of Spacetime as being comprised of multiple Vectors? This is especially so when you consider the time component of Spacetime. Since Time seems to have a direction. Now comes another idea which might be jumping ahead a bit. The power of Tensors is that there's a common reference frame for all observers. This reminds me of how speed of Light (a vector) moving through Spacetime (possibly being thought of as a Tensor field?) is the same to all observers no matter what their reference frame.

Your in-depth knowledge of the subject made this complex topic so simple that even grandparents could understand it. What a masterpiece!

Excellent. The only thing is how do we know that tensors represent the reality of the Universe. Are tensors the building blocks of the Universe? It seems like we can collect these vectors and make an infinite amount of combinations. But by doing so what would we be representing by the infinite combination of the vectors and components? Infinite Universe? And what would tensor look like if we added another dimension to the x, y and z axis? Nice representation and by adding more vectors just makes this more confusing.

Thank you sir❤

Amazing explanation!

I think that the 1.8 K that downvoted (as of Jan 2024) don't want people to understand what a simple concept tensors are...

Excellent introduction to tensors......and very important concept.

i came here because @Daniel Bourke from czcams.com/video/Z_ikDlimN6A/video.html told me to

I love those tools and blocks

Thanks to you for giving us such a good explanation of such a complex and yet fundamental topic 😁👏👏👌
