This is a beautiful presentation of gradient,divergence and curl. These kind of ideas should be exchanged in the classrooms so that the students can identify better with the course instead of just writing abstract equations on the board and expecting the student to understand them.
Watching during the covid 2nd wave. Where is Grad and div ? This clip shows only curl. Be carefull what you say. The BBC can't stand instability. They don't understand it and they do not have the resources to engage anyone that does.
I hope an OU administrator reads these comments at some point because there's huge enthusiasm for the way these ideas are presented here. I would have loved to watch these videos as part of my electromagnetism module.
I learned what to do when I see "curl v" on my exam, but never learned WHY we learn about it. This video and the others in the series are so useful to show students the practical application to what we learn about. Thank you for these videos.
I can't imagine that such a great video can exist. It was a couple of years that I studied about curl, but i didn't know what it exactly was, but now I recognize it very greatly. Thank you very much for this undescribable video
I am very thankful to you to make such an interesting and real life situation video over mathematical physics 🙏 i got it by heart after 14 years of my graduation in physics and 11 years of my post graduation in Electronics, but thanking you to make this attractive video.

+masterxilo the velocity profile is parabolic because at the edges, the velocity is 0. As you get closer to the center of the river, the flow velocity increases to a maximum in the center and thus giving you a parabolic profile. Its called the no-slip condition in fluid dynamics. Look it up
Exactly those things show how mathematicians create maths. It's utterly sad most teachers don't teach like this. It's as if their greatest fear was to be understood and as if the inventors really started with writing a definition out of nowhere.
An excellent short talk. I wonder whether for completeness she could have shown a film of flowing lava - I have one which shows the drag effect of the 'riverbank' very clearly.
Thank you for a good description of Curl. The video should be much longer, visualised flow is a fascinating thing to watch,on it's own. One thing however, is that the OU missed the boat somewhat by declining to fund my father's book, Speculations On Fluid Dynamics which uses Newtonian Principles to allow analysis of flow in unstable states and form the basis of a unified field theory.
Perhaps beyond the scope of this lecture, but when discussing curl in large-scale movement of fluids, (vortex formation in storms and currents) Coriolis force is all important
It takes a peculiar kind of mind to give different titles to three videos in a series, so they don't sort together out of a longer list and don't arrange themselves in numerical order. Wouldn't want that, would we, now? Well done, Open University.
Great video! Question: At 4:30, the ccw rotation of the disc is described as being caused by the downstream flow on the right & the relatively lesser flow on the left of the disc. In reality, wouldn't this give rise to the magnus effect l, causing the disc to float toward the center of the stream?
PHYSICS NEVER FAILS TO AMAZE YOU .............. UNTIL AND UNLESS YOU FIND A TEACHER WHO RELATES THE PHYSICS IN MIND WITH HEART TO GET THE SO CALLED FEEL ( indians be like this sometimes..sir feel nahi aa rha hai lol)

ONLY IF THE PROFESSORS UNDERSTOOD IT THEMSELVES !!
Funny that you say it because in your picture it is you, who is writing some equation on the board

Such videos invoke passion for learning. Thanks teacher.
I love the dude at the end! You can tell that he gets a lot of satisfaction from studying these phenomena.

I have never seen such a great explanation ❤...i expect everyone to explain subject like this
Amazing ! The most impressive explanation video about vector field and curl that I have ever watched. Thank you so much.
brillliant no words to describe how
easy u made this for a lot of people
Great !
A big thanks!
My teachers never told the physical significance if these values. It took around 4 years for me to learn the real meaning.
perfect , epic , wonderful these are the god damn physical explanation that i need ffs
This is why i love physics.It makes mathematics meaningful.
Five years later, here I am, another grateful viewer. Thanks for sharing.
Outstanding. I always search for this type of video co relating the topic with natural example.Great Thanks to you
Now I understand the physical meaning of curl and divergence. Well presented! 👍
This science is real science and weather scientist brought on is a major physesist .
Thanks a lot! A new intuition opens with a new perspective!

Teşekkürler. Bu bilgiler çok işime yarayacak. Gerçekten curl teoremini anlamakta zorlanıyordum. Beni aydınlattığınız için teşekkür ederim.
Came here after almost 3 years and this video impressed me again ,
Exactly those things show how mathematicians create maths. It's utterly sad most teachers don't teach like this. It's as if their greatest fear was to be understood and as if the inventors really started with writing a definition out of nowhere.
Very nicely explained!
Thank you!
Especially the last part!!
An excellent short talk. I wonder whether for completeness she could have shown a film of flowing lava - I have one which shows the drag effect of the 'riverbank' very clearly.
Brilliant explanation of curl I understand things so much better with s visual explanation. Finally I now can picture what curl is
OMG ... now I understood what actually curl and divergence are. Thanks a lot
I never ever thought this can be so interesting. This is really very amazing ❤️
I didn't understand accurately the content. But this the most video that let me understand these three parameters.
Thank you...
for more than 1 year I was in a in a state of confusion about the physical significance of curl, divergence...
thank you again
I had no idea Melisandre, the red priestess, was tutoring physics on youtube!
For the night is dark and full of terrors.
Well, maths really. But since maths is the language of physics ... then yeh ;)
Is it really Carice Van Houten tho?
i ve been trying to understand curl and div for a long long time now i think finaly the 'aha' moment is here
This video takes me back to grade school, but It's helping me in college.
Now I should never forget what the curl vector means physically. Great!

the explanation is beautiful and pragmatic just like your voice. i love you
I liked this sort of documentary type class. Great!
Awesome physical interpretation . We should bring them to text books ,rather studying waste stuff . Pls consider
yes my physics professor sed that video on lms really its a very usefull video to understand this topic
It takes a peculiar kind of mind to give different titles to three videos in a series, so they don't sort together out of a longer list and don't arrange themselves in numerical order.
Wouldn't want that, would we, now? Well done, Open University.
Really interesting way of looking at things. Thank you for sharing
Great ,absolutely great !!! Thank you very much for inspiring me!
The exquisite piece of explanation one coud ever ask for :) Thanks !!
my question always is, what happened to these animations/ animation programs, because they are so good and nostalgic
tremendous outstanding presentation
to the point approach
Awesome!more such vdos on river hydrology will help us..
true beauty of maths
Great video! Question: At 4:30, the ccw rotation of the disc is described as being caused by the downstream flow on the right & the relatively lesser flow on the left of the disc. In reality, wouldn't this give rise to the magnus effect l, causing the disc to float toward the center of the stream?
One of the best videos I have seen on this topic. Kudos for the effort
That was great... Thank you for making this video.
Vortex lines (curl of V) moves with the flow by Helmholtz II
Where 6:34 where The Mersey meets The Irwell river? I think my dad showed them this. It's a free vortex.
Best explanation,thanks a lot
These videos are very helpful. Thank you 😍 ♥
great efforts, and explanation as well
your efforts make me to subscribe
Thank you for this great lesson 🙏🙏💓
please we need more presentation for Naviar stoke equation
Excellent. Thanks for the video !

Great explanation of the curl
Fantastic Explanation of the curl... thanku.. hatsoff
really awesome presentation
wonderful explanation !
sehr schöne Erklärung! vielen Dank!
extremely useful, thank you
Amazingly understandable
Awesome! I love it!
really superb work....
at 7:14, all the arrows except the one at center should point upwards right?? the direction of rotation is same at every point
Thank you ❤
superb....... thank you.....you are great.....
Wow nice explaination
Great video. Thanks
Thanks for providing some knowledge👍👍
first time i got it thnks :)
Oh! Beautiful.
Did anyone even notice that the plus [+] sign in a vector notation does not represent addition? Why don't mathematicians use a different sign/device?
excellent sir...............
Great video, thank you!
اجمل شرح عن الدوران
"The simplest possibility is parabolic" - why not linear (i.e., here, absolute value, to make a triangle)?
because we assumed that velocity on both banks is zero. and in midstream is maximum!
Thank you very much!
amazing xplntn!!
beautiful !
Excellent !!!!
very nice!
Terima kasih pak
What's the difference between grad and div?
Ok this is extra good
How you made the animation ? which software ?
Excellent video. I sort of understand what the hell i’m calculating now
Well if you had watch another video you probably would of understand it fully
what program is used to make this animation????
Great physics .
That was great.
thank you
thank you!!
Emma Thomson here teaching me maths.
wonderful
just wow
Thank you so much!
