Correction at 4:55, the narration should say "counterclockwise rotation gives positive curl, clockwise rotation gives negative curl". The diagram is correct, though.

I'm 41 and in my third year back at school again pursuing different degrees. The pure amount of resources available now compared to when I first went to college in the mid 90s is crazy. And pushing it back to the 70s I can imagine is only more apparent. These kinds of animations are so nice for visual learners and makes it more intuitive when it comes to applying the concepts.

Notice the associated DOME AND black “space” of what is the eye as well. Really think about it all. Consider WHAT IS THE SUN ON BALANCE. (NOW, think about time.) Outer “space” involves full inertia, AND it is fully invisible AND black. Consider one and three dimensions ON BALANCE !!!

Since you talked about your viewers, I'd like to share my experience with 3blue1brown! I am a german math student in 2nd semester and I am SO greatful for every single one of the videos I watch. I always keep recommending this channel to my peers and believe it to be the most... beautiful and informative one on maths on youtube. I love the colorful animations, your voice (it's very soft and motivating!) and - well, in fact, all of it. This channel is a super good addition to my studies, and I want to be honest? I don't think I would have passed my first exams without constantly viewing and re-viewing these videos throughout the semester. Every single one gives the visualization and background I need to understand the topics (and not forget them 3 days later). Thank you very very much for supporting me in, well, the part of my life I need most help with. This might sound dramatic, but I really need you to understand that I mean the words I say; I wouldn't have developed to be the person I am today without all of this ^^ These videos are just fundamental to my studies - everything would be different without them. Keep going!!!

I am getting envious - as a "dinosaur" - how brilliant ways and tools You have TODAY to explain these things so _fluently_ that even I can grasp them finally. When I had some of that stuff over 30 years ago in school, it remained horribly abstract and left me clueless, almost. Especially the question how poeple like Maxwell, having not even an idea of digital computers or visualizations, could "make" those fundamental equations ... so I always stood kinda stuck in between: neither be a total ignorant for math, but also not even close to mathematicians, who always remained as one of the strangest species on earth to me (no offence intended =), as they would thrive in their abstract world called Math, and leave everyone else behind, not even understanding or being interested to understand, why non-mathematicians do not understand them and the matter which is "so obvious" to them. That mind gap is just astronomically great. For me, it is these visualizations being the KEY to grasping. Unfortunately, too many people, even if educated, still mix up grasping with memorizing ... Thanks for this video, most excellent!

I went through Calculus 1-3 with absolutely no struggle to understand anything thrown at me. However, when we got to vector calculus, and especially circulation and flux/divergence and curl, I was kinda lost. I could do it, but I really had no clue why I was doing what I was doing and just plugging and chugging. I could not really grasp these concepts in any way beyond a vague sense that circulation/curl is a measure of how much the vector field flows with a curve and flux/divergence being how much it flows across the curve. Now what this meant or what the resulting answer actually represents was lost on me and I had no intuitive sense of what was happening. I’m glad to say that this cleared things up for me substantially, especially the portion about the dot and cross products and how they fundamentally relate to divergence and curl as the algebraic machinery being used just didn’t make sense to me before.

Thank you so much for making these videos. Previously in my life I had a fear of math and over the pandemic I found a love for it. When it comes to certain fields such as linear algebra, I have found that educators seldom take the time to explain what some of the content means. The content that you provide is super helpful from a conceptual standpoint as a student and I am very grateful that you continue to upload content. I can imagine that your work has done a lot to help others overcome the fear that many feel towards this field. You are doing great work, keep it up!

This fantastic video not only helped me pass my minor subject studies in Physics about a year ago, it also helped me visualize and intuitively understand elementary electrodynamics, which in turn has helped me a ton with developing my intuition of chemistry (my major). And that is only the most concrete example in which being a 3Blue1Brown watcher has benefited me. Grant's videos continuously help me think about math in new ways, and that is already in the process of changing the way I think about science problems in general. Your videos are a phenomenal treasure for us applied math regulars, perhaps even more so than for people who work with pure math. Either way they are consistently interesting and eye-pleasing. Keep up the good work!

Thank you!!!, I have found even in nonmajors courses that by teaching the SHAPE of the fields inferred by Maxwell Relations 1 and 2 makes so much more sense than just diving into the calculus or traditional ODE. Many students today are visual learners. Truthfully, I think that many many of us would benefit from this superb approach to Maxwell Relations--comparing aspects of EM to fluid behavior--even physics enthusiasts, as noted by fellow colleague Stephen Hicks and echoed by myself.
