Long ago, when I took a course on Electricity and Magnetism, the tracher didn't explain anything about curl, gradient or divergence. He only taught us the mathematical way they are calculated. Now, with this video I completely understood these terms. Thank you very much. Eugene Khutoryannky, for this and other axplanations you have given through your videos.
Thanks. I am glad that my videos are helpful. The reason your teacher didn't explain it is most likely because he didn't understand it himself, and he was just repeating it the way he himself was taught. This is a very common problem.
I can always go to a video involving the math of your topics following your newest video and follow it, thanks to how well you organize and present these. Thank you so much
I said that before, but each time I see a new one, I am forced to repeat! You are the best physics/math illustrator on this entire planet earth (known to me)!
These 25 minutes needed your hours of hardwork and it saved my hours of hard work to understand it so easily. I am studying engineering mathematics and wanted to understand physical meaning of Divergence and curl. Thank you, thank you, thank you. 😇
After completing my 1st semester I was totally disappointed to opt engineering because my love 'Physics' was continuously going far to me but thanx for your electric , magnetic field to create an attractive force between me and the Physics. 😍
I am really grateful that I found your channel. I thank you very much for your efforts and I really really hope that you stays interested and motivated in keeping producing such videos.
This video was unbelievably helpful. This has shown to me that I am 100% a visual learner and that I should seek videos like this for topics I have a hard time grasping. I very much appreciate the effort that went into this!
Hi Eugene Khutoryansky This video is amazing! Is it possible in future to cover topics like line and surface integrals and its applications???. Also green and stokes theorem.
these videos are the best to develop some real math/physics intuition, every equation comes alive after watching them in these simulations, thank you so much!
Just when I have a multi variable calculus exam in hours and this is precisely the topic in the exam. Thanks Mr Eugene for a great video, greetings from Mexico.
OMG, it makes so much more sense to capture the flowing particles using a box instead of a ball! This way, you can easily decompose them in the direction of xyz (and generalize to higher dimension)
just an appreciation post. your videos are one of the primary reasons of my interest sparking in physics keep up the amazing work and inspiring people! You should know what you're doing is changing people's outlooks kudos!
It's incredible how easy the video is to understand, even to those without a background in mathematics or physics. The timing is perfect as well as my multivariate calculus final is tomorrow. Thanks!
Another wonderful video! I am deeply impressed by how Eugene (and Kara!) can manage to explain so much math without (or, mostly without) using any formulas!
+Pär Johansson Thanks. What I am trying to do is give people an intuitive understanding of what the formulas mean by visualizing images of what they represent. Once someone has this visualization, they can derive the formulas from the images. However, it doesn't work it the reverse order. Knowing the formula doesn't necessarily mean that someone can derive the image of what it represents. This is why I believe that the images are far more important than the formulas, and the images also make the topic accessible to more people.
+Physics Videos by Eugene Khutoryansky This is perfect for me because I am a pure visual learner and I can't learn anything if I don't see it moving... it's kinda unfortunate, but thanks to people like you, I can learn. Forever grateful here.

Thanks again i think this is my favourite video! It really helped my in my understanding of Nabla notation and Green’s Theorem… explained vis curl and divergance… AMAZING! THANK YOU!
This was very useful to me..as i was unable to understand the physical interpretation of curl and divergence. Thank u so much for this useful information.
The world of physics is full of imagination. Thanks a lot for converting this imaginative world into real world 😊😊👌👌👏👏 The more is our imaginative power the more we can explore in physics. But unfortunately all are not blessed with this imaginative power. But if they watch these videos they can surely develop imaginative power.
As always, an invaluable contribution for those wishing to learn about these topics. Thanks, Eugene Khutoryansky. Have you considered making an Android/iPhone app, in which these physics concepts can be used and tested?
This video is amazing, i'm a visual kind of person. Explaining with animation helps me a lot to understand the concept! Thank you for making the great content! :)
You can also have divergence if the volume is accumulating particles by increasing the particle density inside, without actually destroying particles. I think that would be important to mention.
Not if the region has a volume that approaches zero, since there is no place for the extra particles to go. And divergence deals with regions which approach zero volume, so that you can specify the divergence at each point in space.
@@EugeneKhutoryansky Well,in that case it can take an infinitesimal amount of particles. The point is that if density is changing you have non zero divergence, that is what the continuity equation is telling you. For example consider air flow. The total mass of the air in the room has to be conserved, so you are not actually creating or destoying any particles. But if the air density is changing in some point, the air flux has non-zero divergence in that point. See en.wikipedia.org/wiki/Continuity_equation#Differential_form.
Woah how about your grade? I just have my exam of multi variable calculus too in hours and the professor said in class "just study divergence and curl of a vectorial" and I found this
really thank you i v been trying to understand the curl for years and i couldnt but today finally i understood it after i watched this video really thank you
The three dimensional representational keep the mind clear And not flattering out as it can when things are written on a blackboard, thanks I find the imaginary concept insightful It makes you think that light has its negative inbuilt speed of light component So that a curl ,and divergence dampening effect stops opposing light source's from exceeding the speed of light
Liked the presentation. If you assume that the same reference frame and there are two sets of vectors that are congruent with each other but in opposite directions, they would sum to zero. The same could be said for the associated manifolds, as demonstrated in the clip. Seems trivial. Like, water being pumped through tubes or hoses are physically next to each other but with the water being directed in opposite directions by the hoses or tubes --- if these setups were curved say,? But you can fool around with that setup. You can contrive to tilt one hose with water flowing through it, 20 or so degrees when referenced to the other curved hose, say, and as the previous computed vector nulling goes away and there then might be seen some thrust as per Huygens' equation F = ma = (mv^2)/r, which applies similarly to to associated vectors and manifolds as suggested above. ... tubing with water flowing through it, draped and pined to a 20 degree wedge shape ---- folding a circle in half. Sort of trivial. The ideas are pretty simple, and if you factually create a physical model or models, the simplicity becomes pretty obvious. Generally, I think that many get put off by the wordiness of the explanations, which is understandable. But, I wonder if NASA knows of this trivial exercise? See: 'Traveling Through Space --- Without Rockets: 3rd Ed.' by James G. Parsons. As seen, complete with copious spelling and grammatical errors, on or at maybe Ammazson?
Given the divergence and curl, can you calculate what a vector field is that has said divergence and curl? And will there be a general solution of vector fields with said divergence and curl that only differ by a uniform/constant component? Similar to how given a gradient vector field of a scalar function, you can calculate what that function is. And you can calculate the general family of functions that have a given gradient, which only differ by a constant term. So the gradient vector field tells you everything you need to know about the shape of the hill, and the only difference between all the possible hills that could have this gradient, is the overall elevation.
Thanks a lot, Eugene! Your video helped me a lot a lot a lot. I have been grappling with these concepts for a long time now! Subscribed! :) Rarely do I subscribe to a channel after watching just one video of theirs.
Thank you Eugene for giving me the great intuition about divergence and curl.But I have questions,if we consider an electric field produced by the point charge (+ve).As we move radially outward from the source charge then the magnitude of vectors associated with points that lies in my path decreases,Does that mean that those points behaves as a sink?If it is so why we take divergence 0 not -ve at all the points except at the charge position where we take divergence+ve?
No, those points do not behave as sinks. Think of particles being generated at the center, and then moving radially outward. The particles don't disappear into a sink as they move outward, but they get spread further and further apart. Therefore, the arrows describing the particle density get smaller as we move further away from the center.

Finaly I understand divergence and curl thanks a lot dear.....
Really amazing, you deserve Patreon support!
Thanks.
Thanks for giving this wonderful video
Thanks.
Thanks a lot, Eugene! Your video helped me a lot a lot a lot. I have been grappling with these concepts for a long time now!
Subscribed! :) Rarely do I subscribe to a channel after watching just one video of theirs.
+Geet George, thanks. I am glad you found my video helpful, and I am glad to have you as a subscriber. I hope you enjoy all my other videos too.
Great job...effectively helping my understanding of difficult topics..
+rokandu, thanks. I am glad to hear that my video was helpful.
I never quite visualized Ampere's Law well, you helped me a lot in this video!
You are doing a really amazing job....
Thanks.
Thank you Eugene for giving me the great intuition about divergence and curl.But I have questions,if we consider an electric field produced by the point charge (+ve).As we move radially outward from the source charge then the magnitude of vectors associated with points that lies in my path decreases,Does that mean that those points behaves as a sink?If it is so why we take divergence 0 not -ve at all the points except at the charge position where we take divergence+ve?
No, those points do not behave as sinks. Think of particles being generated at the center, and then moving radially outward. The particles don't disappear into a sink as they move outward, but they get spread further and further apart. Therefore, the arrows describing the particle density get smaller as we move further away from the center.
Poetry in motion !
Thank you, I really like the combination of music and math and the super illustration of the sciences .
Thanks.
superb graphics, very informative and educational subjects, please keep up the terrific work, which I know is not easy
+Mystl2, thanks for the compliment. More videos are on their way.
Really its a nice work again...!! Thank u so much for this beautiful sharing
You guys just blew my mind
