    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.

      Funny that you say it because in your picture it is you, who is writing some equation on the board

      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

    My teachers never told the physical significance if these values. It took around 4 years for me to learn the real meaning.

    +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.

  • @factorylad5071
    @factorylad5071 4 года назад

    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.

  • @robertharvey6725

    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?
