I'm an engineering student and NONE of our lecturers have the ability to induce interest in the class like this man does.
Very true. Most of them are only good at grading you, after you have searched everywhere to compliment their inability to lecture.
so true lmfao
That's because your professors each 1/10 of a salary compared to this professor's.

I'm disappointed, I was expecting an induction joke in the comment thread given he use of the phrase "Induce interest"

Yes present🤟
I'm student of class 12 from INDIA ❤️ and I genuinely enjoy to get knowledge from such a wonderful teacher with a good sense of humour how to teach and when to make students laugh.
Seriously I very blessed to see you sire from sitting in my room in my country India.
It's my pleasure

Same here bro my coaching teacher always blames me that i can't do good in physics!
Now i can blame him that he hasn't humor of teaching physics 😅
We are lucky that he uploaded these lecture on CZcams, for free.
thank you sir ❤️
truly
Lucky are those who saw these lectures live ❤️
They are'nt lucky thwy are brilliant they are mitians i guess
Stresssssssssss
Not luck, determination and talent get you into m.i.t. .......I had the talent but not enough determination, so my undergrad was W.S.U. But the teachers I had were great, mostly, bc I took all my early calculus, chem, and physics at a community college (great life hack, I only ever had 1 T.A. at WSU, the rest of my instructors were professors.)
Which book he referring to ?
❤❤❤❤
He is the coolest physics teacher ever.
Except maybe Feynman himself. Check out some of his lectures too
Feymann lectures were incredibly deep
Nah!!!!! Search on Yotube Physics Wallah he is the best
@Mouleesh exactly, 😂😂😂
Let’s not compare the greats to each other
I thought I made a mistake, taking physics in high school, This lecture made me believe I didn't.....I can't thank you enough sir!
Lots of gratitude from India
Same :)
That's the same for pretty much every Indian student... We find physics synonymous with Nightmare !!
Where it is ongoing this class
same here bro
You did make a mistake
Taking Physics in "India" that is
I am sure you have heard this countless times but it bears repeating - you are an exceptionally talented and unique individual. I have a background in engineering and I can say these lectures are one-of-a-kind. Such a pleasure to watch and an indispensable resource for me in preparing to tutor my small group of students. I share the videos with them!
very nice - you should also tell them where they can find my videos.
What a time to be alive to get a chance to watch this amazing lecture over the internet without going to the MIT from several 1000 miles away. Amazing
I like the way he draw those dotted lines!! drrrrrrrrrrrrrrrrrrrr

How is he doing that😮😮😮?
seriously, man too fast drrrrrrrrr..;-)
Maths teacher in my school used to do this each time.
Take the chalk and angle it up. Then push in the direction that you want to go and it'll dot.
Profesor Lewin,
I am an airline pilot about to retire in 4 more years. I was suggested by CZcams one of your videos, and it piqued my curiosity.
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.
Professor Lewin, you have demonstrated to me that you can not be too old to learn something new.
Well done, Professor Lewin, I salute you!
Airline mechanic here :D also find this man to be an absolute treat to watch and learn from!
Hi Professor Lewin, you have succeeded of making me to love Physics.
Great to hear!
I'm NEET aspirants and I used to hate physics but now I love physics , I even taught my friends .
Thankyou sir and huge Respect sir 🙃
So neet clear hua i guess , congrats

I hope someday schools wil be teaching physics like this then each and every child will fall in love with physics
Well that would require i) Enthusiastic teachers and also students capable of being enthusiastic BUT even more importantly - All the money required for these demonstrations and experiments and also for enough salary to the teachers like in this case.I learn the topics taught here in 11 and 12th grade in high school and although my teachers don't have such charisma, all they can do is tell and also making an effort by themselves for doing something extra would require some work which they can't justify in front of teaching the way they do now.
Bruh walter is paid like 100 times what school teachers are paid shut up with your impractical ideas
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?”!
@@gweilospur5877 except what he is teaching goes against the globe earth religion
@@aayushswami498 The average US school teacher gets 65k/year. No professor gets paid 6.5 million/year. I doubt WL got paid even 5 times that.

I am class 12 th student from India.And during the early years I loved to study about concepts of physics but when I had taken physics as my subject . I was not able to go through the topics properly.I was not able to understand. And reason was one and only as said by Walter Lewin sir that THE TEACHER WHO MAKES PHYSICS BORING IS A MURDER.But today I felt that I am lucky cause I find Walter sir's these physics lectures playlist.I am so thank full to the whole team of this channel cause they have somehow saved my whole year .THANK YOU SO MUCH .I WISH LONG LIFE FOR WALTER SIR so that he can give us more like these wonderful lectures.

Lectures by Walter Lewin. They will make you ♥ Physics. Sir u are the best teacher I have seen till now. U are immortal through these videos, love u sir 😍
Right bro😂😂😂😂
Can someone explain me the joke plz?😓
@@dikshikasharma5740 You need electricity to think but some people can't think even with electricity!
I am fortunate to stumble on one of your lectures while shuffling through the web, and I am stuck with your channel for a while Dr. Levin. No words can express my feelings about you and your fabulous teaching. I am a senior IT professional and an Electrical Engineer by education. I already completed 8.01 series. Thanks again for letting me revisit and see physics passionately which I might have pursued just as a part of academics and even scored high although aloofly 🙏
Your vocabulary is nice
I am class 11 student just entered this at random. To be frank I read these stuffs when I was in class 6. We just read these things. But things will get wonderful when you actully do it in practical...LOVE FROM INDIA.. :) from all NEET and JEE aspirents...!
Man I am in 10th and my teacher never explained it to me in this way. I am thankful to such great teachers who keep people's love in physics alive. BTW if you like maths then u should definitely check out eddie woo
Im also in 11th from nepal😊
bro what do u think should i follow these lectures for jee prepration
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.! :)
Thanks for your very kind words. 💥
Lectures by Walter Lewin. They will make you ♥ Physics. Wow! You reply fast! And I love it that you're so modest. You entirely deserve the praise, and modesty is one highly unlikely quality in the people of your calibre. Highly appreciate it! 😊

I want to share a question with you.There is a question striking my mind for more than 1 year. I tried to find the answer from various books and from online method by the answer was not satisfactory. The question is suppose it's raining with some constant velocity and a boy have to go through distance D so should he run as fast as he can or walking at different velocities makes no difference, the condition is he should get less wet. Or if walking slowly or running fast makes difference how can we show it mathematically.
After not getting a satisfactory answer. I worked on this question. it took me 7 days working whole day and late night and I came to derive an expression which would answer many such questions and can be used to calculate more information during rain. The outcomes from the equation is really mind boggling. I've defined some new terms which can make make the equations (theory)useful. It is almost 32 pages long. It will be a great help if you will verify my equations.

I'm in my final year of schooling in Australia. I take physics, my physics teacher is alright, she covers a lot of topics in a single lesson but doesn't necessarily uncovers them. We're doing electricity and magnetism now and no one in the class gets it, including me. But wow, just watching this lecture, I have huge respect for Mr. Lewin. If he's reading this, I just want to thank you so much. You've literally opened my eyes to a world I was oblivious to. Just amazing. Thank you.

Right now I'm writing some notes for my interview with my science teacher and it's been really stressful on me, but when she had given us the link to this video for 10:02, I ended up watching the entire lesson, thank you I learned a lot!
Hi @oompa loompa, I'm also going to be having an interview on this topic this week. Would be possible to get some advice?
Well, I can't imagine a university professor to be that much frank and that much attached to the students. He is way funny an conducts a lotta experiments to make students understand the concepts in a more precise way. And surely his way of teaching is kid of amazing. Hats off to you professor Lewin.
I love this guy. Mr. Lewin makes learning fun especially with the whole pandemic going on. Its so reassuring that there are people who know how to teach in a manner that not only makes it easier to understand but also more enjoyable, which is something schools lack today.

Hii Sir, this is Ashutosh (from my dad's account ). I really want to thank you for your lectures which are indeed masterpiece.
I aimed to join IIT Bombay and was preparing for its entrance exam which is on 3rd April. 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. Your videos really inspire me.

seriously I do not even like physics which is taught in schools, I read some about modern physics out of the school's curriculum, and it is so fun to know about the dual nature of electrons, I guess our bad point of view on physics is from the way they teach us... It's my last year in school but even though I didn't find the coolest way in schools to teach a fun subject like physics, as you know what you need you get it on the first platform you open cause social media know you more than your self, although these videos are 7 years ago, it's still a masterpiece, now I can say I found a teacher who teaches in the right way which mixes science with fun, although my passion tends to medical terms I won't stop listing to your videos, sir ... these students who saw the lecture live are super lucky...at the end thanks sir to make our point of view changes towards something important like physics.💞

Now I understand why I feel shock whenever I touch the long rod where my family dry their clothes. Everytime we remove the dried clothes from the rod, we drag them down with force, we are actually charging the iron/steel rod with clothes. After a while if we touch the rod, we feel a little electric shock due to the charges present on the rod.
(Though it won't happen often but now I understood the concept of it).

Great lectures! Thank you for making these available, i'm sure students all over the world appreciate this as it is very helpful and makes learning physics fun and interesting.
I love all this stuff conceptually, but my mathematical education as a child all the way from algebra to pre-calculus was awful. My small town public school teachers couldn't teach math and would even have us take "group exams" so we wouldn't fail and make them look bad. I took geometry and "learned" mathematical proofs from a football coach who couldn't spell "quadrilateral" and got fired for being abusive to the football players he was coaching.
I never enjoyed math as a result and thought it was all wicked nonsense until I got exposed to it much later. In another life I'd be graduating with a STEM degree, and I'd love to have one still, but I've got no time or money to start my degree over with a new major, or start taking introductory higher mathematics, so it's the I.T life for me.
Thank you for posting these lectures Dr. Lewin; this sort of publicly-available knowledge from quality teachers like yourself is the future of education. I hope you understand how valuable these are to people, and how much myself and others appreciate having them.

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 🤠
