It is needless to say that I have already subscribed to your channel, and I have started to watch the videos of your lectures. They are addictive even without the required level of knowledge in physics. I only wished my teachers and professors were as enthusiastic about teaching their subject matter as you are.

[@gweilospur5877]

Most of what he teaches in these lectures is high school physics, I guess US colleges do that to string out the course to extract more money from the students. That’s why a U.S. bachelor degree takes four or five years while a U.K. bachelor degree takes three years. He is lecturing to dozens of students, if you understand economy of scale that means far more resources can be put into his lecture than a high school teacher can put into a lesson. His practical demonstrations will be resourced and set up by lab technicians, not by himself. I am a Physics teacher, many of these comments are what I call the “Bill Nye Effect”- I show a younger class an episode of Bill Nye the Science Guy and they say “why can’t our lessons be like that?”!

I do not even know where to start from. I absolutely love your lectures. I cannot dare imagine the hardwork that goes into preparing them.! I mean, if I wasn't told to check out your lectures by a friend, I would have missed this great work! I'm currently in the XII grade, and Electrostatics is like the first unit of our physics book which comes in totally scary two big volumes. And such scary books really don't serve the motivational purpose. I'm more like depressed reading it. And when you don't have a Physics teacher at your school, you have no option but to rely on your capability of comprehending things as printed and published down in the book. So eventually when topics like AC and Waves started bouncing of my head when I didn't even have the basics of electrostatics cleared, I got demotivated enough. I had started hating the subject and the beauty behind physics faded somewhere there. But, ever since I've started watching your lectures, my love for physics has rekindled. I cannot thank you enough for that. And right now, I am so gravely jealous of these students who got to sit in your lectures and watch you live at MIT. I'm a big fan! Damn! I so much wish that I could see you in person and then I would have learnt to draw them sleek dotted lines.! :)

Every teacher teaching IIT aspirants, suggested me to solve questions from I.E.Irodov and H.C.Verma for physics . But I was not able to solve questions from either of the books .They were really hard for me. It was a week ago when I open youtube to learn electrostatics and I saw your videos. I started watching your lectures which helped me a lot to solve those questions. I can now solve those questions in very less time. I am left with entire physics but electrostatics to solve . I watch your 3-4 videos on a chapter , open my books and solve questions. I have wasted nearly 1 year and now I only have 3 months for my exam. However , I won't lose hope and continue studying.

Hi Sir, I am from India and many physics teachers suggest us to watch ur lecture......I actually hated physics before but after hearing to ur beautiful and mind blowing lecture i enjoy learning physics. I love u and ur lecture Sir. I SALUTE U

[@sachinIITD23]

Yes sister, I always feel proud being a physics dude by making him peeps fall in love with the beauty of phy!

sachin raj verma I’m in 10th and I have watched literally 60%+ of his lectures and now I’m sure what I’m going to do in my life.

[@shankshank1529]

[@Shubham_pandey-nk1un]

You should also watch Mr. Pradeep Kshetrapal Sir's video. You will like them

[@Telugureality4452]

He is best teacher , who I never seen in life till now . He is great. One day I'll try to meet him . And I want to listen his class on live in front me

[@rvj29]

walter levin sir.... undoubtedly you are a great teacher... As a physics learner ( I don't have courage to say physics teacher hence i used word learner) you are really inspirational.... lots of love from my side....

[@anshikasingh3965]

I am class 12th student and after watching this video I fall in love with physics........For me you are a God of physics............ Lots of respect and love from India 🙏🙏🙏

[@tathaYm]

Teacher like you is what i have missed in my school,college and university....really feeling sad....from india

As an ECE graduate, It was difficult to understand the lectures given by the lecturers during under graduation and even after that. Electronics is difficult to understand unlike other subjects where things can be understood by touching and seeing. Electronics can be understood only with solid understanding of basics then by experiencing it and watching the videos like yours. I started reading "Lessons_In_Electric_Circuits_Volume_I_DC" by Tony R. Kuphaldt. It was quite easy to understand than other books where the approach was practical. The same way you too explained, and it was a good session. I'm happy to be an Electronics Engineer 🤠

[@marvelousworldofk6008]

I love your lectures so much sir 🤗 and now I'm thinking as long as there is a master like you in this world , physics cannot be difficult .

[@fahimmumand]

My sincere admiration for the living legend, you made my day.

[@yudhakr]

i could not even give a comment here without electricity, you are awsome

[@indrajeetvarma5821]

Your reading does not feel boring at all and studies become good.

Already studied AP Physics (algebra) in high school but taking it in college was a little overwhelming... but this video was an amazing refresher, and actually made the whole nearly 50 minutes entertaining too. Thanks for such a great lecture!

[@vivekshri]

What I realised in this class is that My education wasn't as bad as I thought. I too have studied all these. And I am proud of my education and Sir Lewin! 💕💕💕💕💕💕

[@siaripop7]

The best physics teacher ever! I'm in my 70's, great time to learn what I forgot, or didn't learn the first time around. Thanks Professor Lewin!

[@baxtermason6909]

...same here...EE in my 70's...supposed to be reviewing a couple of government projects; however, this is much more satisfying...I'm reviewing charge and matter and will end up with EM fields...always good to go back to basics periodically...LR.

[@mohammadzolfaghari441]

In my belief you're biggest scientist of the new age and you are best physics teacher for all time

[@ARStatusbyayanroy]

There is a strange filling of satisfaction after finishing each lecture....

We have never found any teacher in india like u except verma sir and i am damn sure there is no one like u in the whole world ... Watching u on 2021 march 5 ... A fresher here and u have made my journey as a cake walk of understanding concepts thanks alot

[@winfry119]

Algeria must adopt this method of teaching physics. I am a huge fan 🥀 thanks for the lectures and be safe professor 💚

[@omsenapati4858]

I am Bsc first year at IISER Berhampur and our sir told us to watch your demos and i got a whole lot of great experience thank you sir for providing high quality education.

Amazing way of teaching sir, definitely you'll be remember for the centuries. Only a physics lover can understand you

[@varshitajain___]

he is really a great teacher he is even ensuring that basics get clear

[@KeithandBridget]

Part of my mission to watch all your lectures. Much more fun than watching TV.

[@lecturesbywalterlewin.they9259]
