Hi friends, thanks so much for watching this video! Now that you know about Grad Div and Curl, check out my Maxwell Equation playlist if you'd like to see how they're applied in the world of physics! th-cam.com/play/PLOlz9q28K2e6aNgl1zt1xccyy4Ofl3YAk.html
Please cover the remaining equations so that you explain all 4 of them in both their integral and differential form...!!! It's the need of the hour Parth 🙏🥶
This video is very good but does not make use of Geometric Calculus, so will make movement to 4d and the Dirac equation a bit harder. Would you consider presenting and explaining the Maxwell equation of Geometric Calculus? The symbol del/nabla is used in Geometric Calculus for a similar but more general operator ( a box is sometimes used to make it clear that it is not a 3d Del but the Dirac operator acting as a derivative of a point on a higher dimensional manifold. Del F = J is the Maxwell equation. Del F = Del dot F + Del wedge F. F is a BIVECTOR field.

In 1986 or so, my differential equations instructor (Dr Joseph Egar, Cleveland State University) defined operators thusly: "An operator is a animal that eats functions and spits out functions." Then sometimes he'd correct himself: "well, not so much spit them out, they come out the other end".
idk why but lately ive been seeing a lot of physics and math comments from "1986" talking about their experiences. Can sum1 pls tell me whats going on?
@@Sasukej2004 - I honestly could not begin to guess why that is. But, coincidently enough, in 1986 I was studying math and physics at university so.....
It's great that Parth Explains the Intuitive meaning of these operators. We use these in fluid mechanics. It is hard for most students to understand what these operators really do. Keep it up!
I would rather say it's hard for most teachers to explain how these mathematical symbols does represent the concepts more intuitively. Generally, students will understand the meaning of these operators if they are clearly defined in their simplicity as in this series of videos by Professor Parth G. I am in awe at the simplicity of which Professor Rarth G explains these seemingly complex concepts. Kudos to the good Professor!!
This is by far the best video I've seen on youTube that successfully explained me the physical significance of gradient. Thank you so much for this. The education system failed to let me appreciate the actual meaning of gradient for almost 6 years. This guy made me appreciate the idea in 5 minutes. Superb.
Wow! I’m going to have to watch this video clip multiple times. There is a lot info in this one. I’ll have to go back and rewatch your Maxwell equations video clips, too. I always wanted to understand Maxwell’s equations. I’m putting this video on my favorite list now.
Wow, what an excellent video! Thanks so much for explaining so clearly. I found particularly helpful that you give the “types” of each operator, saying what kind of field they operate on and what kind of field they produce!
My friend you have such a gift for exposition please never stop. I'm in awe. Have watched just a few videos but immediately sub'd. In fact they're so good I've had to pause them at times and go make a nice cuppa coffee and come back later to enjoy with pad and pencil. Why oh why didn't we have teachers like this in school!!? Can you imagine on the Internet with comedy videos and cute animal videos yet you're making us chose to return again and again. Pure talent man you're opening new worlds for me. Now one of my top 4 sites for Science in general and top 2 for physics. Thank you
Oh my god, this is a gem of a video. Today was my first physics class in undergrad and I did not understand head or tail of this whole concept but your animations and explanations have made it crystal clear now! Thank you so so much! This really made my day!
Hi Parth, recently discovered your vids and am binging on them at the moment. They are all fantastic, in particular skimming the maths in favour of focusing on meaning. I really think you get that balance just right, for me anyway. This one is my favorite so far. Have loved to try and visualise Grad, Div and Curl for decades now and this was the best explanation I've come across. I'm going to try and give it a run with my wife, who doesn't seem to have my (our) love of physics. I think Grad, Div and Curl can all be explained with a swiming pool and velocity (speed) for vector (scalar) fields, so will supliment your video with my explanation of that. Keep up the fantastic work mate!
Watching these makes me want to freshen up on my calculus. It's been almost 30 years. I do remember curl and some of vector calculus, but it's foggy and I need a refresher :)
I am a first semester calculus educated college student, with some second semester calculus, as well. This video is very cogently presented in a way that switched on a light in my mind. I greatly appreciate this wonderful video.
Back in college I was taught how to calculate these things, but never properly shown what they actually do (or didn't study properly to grasp it on my own). Thank you for this video, it was great.
You always be able to explain the complex mathematic and physics in easy way so everybody could understand the subjects. Really enjoy watching your channel.
Excellent thank you, One of my Covid projects was to have a thorough understanding of Maxwell's Equations, which I last studied at Uni, 40 years ago! Back then, I took a semester course and got a very good result, mainly because I understood the Math (i.e., the Del Op gradient, Div and curl. Now the physics I still. after the course, I did not have a clue on the meaning of Maxwell's equations; now with your review of the Grad, Div and Curl I'll attempt to have a deep understanding of the ME ....Let there be Light! Again Parth much thx
Dude! You're beyond awesome. I watch physics and math videos for years (for the sake of fun and curiosity - I'm not a professional scientist, I'm a professional musician ;) ) and I FINALLY got it. This was my "aha" moment and I actually found these equations intuitively simple thanks to your straightforward explanation!!! Thank you!!!
It's funny, I subscribed to your channel 3 weeks ago, being curious about the Lagrange mechanics. So, you posted a video about virtual images, 2 days before I get to this subject on my course, and now you posted a video about these operators, on the same day I got to Maxwell Equations hahaha
Excellent video. Very interesting, informative and worthwhile video. I never thought I'd see such an informative, yet concise explanation of these topics.
Thank you for your videos explaining formulae. I especially like your analogies drawn with real life phenomena, like vectors as wind charts, and, in another video, divergence compared to running and draining a bath. All these make understanding easier. Thank you
Good vid; I especially like your first def. of the Del. operator on a scalar field. In your discussion of curl, this would be better served by using geometric algebra instead of the std. curl. The "outer" product makes far more sense then the cross product.
Hi parth , It was a great video.... I learnt the practical way of thinking how this operator works..... Request : Do a video on ORBITAL MECHANICS , or Equations related to Space science and rocketry......
As always, Parth G's presentation is lyrically beautiful, concise, swift, and very informative! (As a point of comparison, I'm thinking of the "classic" by H.M. Shey entitled "div, grad, curl, and all that" [sic], with its odd sequence [Chapter II div, Chapter III curl, Chapter IV grad] and its bizarre notation explained on page 4n1; ugh.)

Hi Parth, great video. Can you please discuss about cooper pairs in superconductors in your next video?
Thanks

Hi Parth. I really like the way you explain difficult concepts in a very easy and relatable way. Could you please make a video on tensors.
😂
This channel is amazing, you always find a way to explain things better than my professors.
@ཀཱ no thanks, it didn't support xroach last time I checked
Thank you
I thought that I was the only one 😀
This is one of the best video explanation, I have watched on the vector calculus. Thanks a lot.

The best explaination on TH-cam!!! Finally not confused anymore.
man, this man makes it look much easier
I’ve been subscribed for a couple weeks now because someone mentioned the Lagrangian to me and oh boy I’m staying subscribed
nothing else you are just creating scients in this era using your videos dont stop this keep going just damn great contents
very insightful yet concise, thanks !
This is EXACTLY what I needed. You explained everything I wanted to know but didn’t know how to ask.

Honestly, I love these explanations, they are very intuitive and brings out the physical meaning of these concepts
This video is AWESOME ! Well Done !!!
You're a great teacher Parth

Wawooooo Amazing Job Bro 👍.
Very short time to all my questions is clear.... Thank you so much 🥰💖
An extremely clear explanation. You sure talk about Maths gooder than a lot of other people.
This is so beautiful！！I think I got it.Thank you!
Just a few realize how amazing is the musical taste ,which Parth G has 🤘🏻
WOW in the middle of your video i paused and put like and subscribe and then i resume:). Rocking bro
You are an outstanding teacher
Thank you so much
I love this guy! Wish he'd been my physics prof back in the day!
THANKS A LOT SIR, FOR SUCH NICE EXPLANATION 🙏🙏
I wish my teachers during my Physics years had taught me operators like this... Thanks, Parth!
Dude! You're beyond awesome. I watch physics and math videos for years (for the sake of fun and curiosity - I'm not a professional scientist, I'm a professional musician ;) ) and I FINALLY got it.

Beautiful presentation, as usual.
One of the best and most concise explanations ever
Thank you so much
Why youtube algorithm doesnt show excellent videos like this
Liked and subscribed
areyyy Parth G, you did a great job making this video....finally got a clear insight on wat all these terms mean!!
I'll be writing an exam about this topic soon and this video couldn't have come at a better time. You da best Parth!

eyyy same here, started with lagrange few weeks ago too.
I have a feeling that this guy is teaching the course you're studying hhhh
@@yassine-sa Or maybe some teachers are stalking our youtuber :)
i was searching a legend like you to explain things in a smart wayyyy... since 2020
Vector calculus love it
Nice and clean explanation. Billuruna saglik.
bravo man, you are truly gifted for teaching physics! sharing with my son;-)
Thanks Parth G
Such a clear explanation! Keep up the good work bro!
Excellent video. Very interesting, informative and worthwhile video. I never thought I'd see such an informative, yet concise explanation of these topics.
Wow! Clear and concise presentation! Thank you so much!!!
Awesome vid Parth, thank you!
You are teach us better than our doctor 👨⚕️ of physics
I really enjoyed and found the video helping
Clear explanation of these concepts. Well done.
Great explanation. Thanks!
Thank you for your videos explaining formulae. I especially like your analogies drawn with real life phenomena, like vectors as wind charts, and, in another video, divergence compared to running and draining a bath. All these make understanding easier. Thank you
keep it up...we need more of them to make education exciting!
excellent explanation 👍👍👍👍
Sir you are doing a great job...
Curious minds are happy now
Thank you sir
Perfect explanation, perfect speech, thanks, it is good for us to watch your good job.
Brilliant video, thank you
thank you, this is perfect. exactly what i needed.
this is amazing . Sir I don't know how to say thank you to you......
lovely explanation
Wish I had had that succinct explanation at university. Nice video.
Perfect explanation! Thanks so much!
Outstanding explanation as always.Thanks a lot Parth.
Great insights.... It gives felling of nebla operator... Thanks..
I think we will need that last Maxwell Equation!
Great video as usual.
Hard things are explained in easy way. Good work! 👌 Thank you. 😀
Thanks a lot, im taking a numerical methods for PDEs course and i dont have the background in vector calculus, this video helped me a lot
Great video. Excellent resource for Physics teachers such as myself.
this is AMAZING! thank you for a great video
if maths was taught like this in schools, we all would be mathemticians now! genius!
If math teachers understood the math then it would be taught that way.
Excellent video,thank you very much. Your videos or so well done and enjoyable.
Amazing way to explain . Before this video , I have no idea what these things mean. 😊
Fantastic explanation 👌
This was beautifully explained
amazing and clear explanation
Nice explanation
You explained it soooooooo well, thanks a lot dude and coincidentally my name is also Parth! 😂😂

Hi parth , It was a great video.... I learnt the practical way of thinking how this operator works.....
Request : Do a video on ORBITAL MECHANICS , or Equations related to Space science and rocketry......
Some day ago i read in my undergrad course, pleasure experience.
Your videos are amazing.
amazing video, keep up!
