The way you glide to make the dotted line is so satisfying
@Chris Metcalf Lol...Dark humour...😂
Chris Metcalf oh my goodness 😂
isn't that amazing? how he does it is unbelievable.
Yes brother....
I was confuse in 1st time and
In 2nd i understand this
I'm pretty sure its a different kind of chalk. It looks different from the others
It is (somewhat) a mystery how your lectures appeared in my recommended, but I'm glad they did! I love these!
:)
I'm from india and class 12 and i preparing for iit jee and sir your lectures are more than enough for me and im very blessed to have you in my life i started loving physics because of you thank you sir.
It's my pleasure
hello hope you are doing well i am also preparing for the same exam can you tell me if his lectures and pyq are enough for mains
Did you clear jee ?
Experiments are everything. I had this 802x course with Walter Lewin and till today (10 years later) I still show those videos to my students. After all it's hard to find good experiments to show to our students. Make them ourselves is expensive, so Mr. Lewin's experiments help a lot my students to understand physics SEEING it !!! Thank you Mr. Lewin 🙏
Which class do you teach?
It is about 20 years previously recorded lecture.
I'm 17 years old, and I'm physics student at Portugal, I saw all 8.01x lects, your classes make physics something interesting, thanks for creating this youtube channel. Honor to hear you lects, thanks Sir Walter.
+LopeSAURUS Thank you!
+Lectures by Walter Lewin. They will make you ♥ Physics. I have 1 questions for you. Have you thought about lecturing the world? I would love to assist one lect LIVE
+LopeSAURUS I am teaching the World. My lectures are being viewed yearly by more than 6 million people from more than 85 different countries.
same im 17 too , and i love watching sir's lectures , they teach a lot rather than just memorizing physics.
Thank you for these. I'm a high school student, and these videos absolutely make me love physics more and more everyday. :D Sir, you've persuaded me to continue to university with this god tier -stuff.
+HanajimaSensei That's great news Hanajima, you made my day!
Hey, so how are you doing?
@@ftyrone5719 yeah I wonder it, too
I graduated as an electrical engineer in 1979 and love Walter's explanations. I work extensively in magnetics and all of his physics lectures are a great review to help keep me refreshed on the electric and magnetic concepts.
Eggcellent lecture
Egg omelet on his shirt , ikr😂😂😂😂
@@abc-dx3dd Sunny side forward..
wow
prof lewin!!!
loads of love from INDIA!!!
I'm just a high school student here...but yeah I am in love with physics just because of you!!!
May be in future...Physics will be my wife!!
:)
Hahaha😂😂
Ya! Awesome. This is where physics comes into life!! I am a school student. Really, physics is lame without imagination!!
I am also from india
🤓😂
His breakfast was so charged that it got stuck to his shirt for the whole lecture! Amazing.
😂
Better luck next time for a good joke.
🤨
🤣🤣
Because he is just overwhelmingly positive!
Imagine anticipating every class lecture with this professor. Very memorable experiments.
He's such an enthralling teacher that I didn't notice the fried egg until 17 minutes into the lecture lol.
For my exams these lectures made me to score top rankings .... Love him and his lectures .... Proud to be ur online student sir might u dont know me now but one day i will make proud u to have me as ur online student and this is my adhere promise with ruthless determination ...
he definitely is going to be an inspiration for a physics prodigy of our generation.......
two words: Richard Feynman
For sure, when someone makes you love physics, you won't forget him
Completely
These are great :D Getting more into electricity/electric engineering and I always hated when I was told to not worry about how things work on a deeper level and just learn Ohm's law (which is of course a valid law, but I always wanted to know where it comes from, and get a mental picture of how stuff works on a more fundamental level). And this really helps. As a side-benefit I even get to refresh my math a bit on the assignments
:)
Prof. Sir Lewin, You are doing a great favour to the mankind. Believe it or not. Although your body may have grown older but your passion to teach is still as young as it seems in these videos!
May God grant you a long life!!
{I feel very lucky that we are able to reach you}
Any neet or jee one??

Have you find assignments ?
Ha
Yes ..... aim after jee :to do masters from mit
"Don't be late. I mean you, pretty boy". It can be a meme
Lol were they being serious??😂
did the 100th like
what was that tho? i didn't get it
@@myrasinha6428 it's the funniest seriuos way to scold students for being late

These lectures will help me alot this semester, thank you teacher.
Greetings from Colombia.
GREAT!
Indeed, your way of explanation and demonstration of physical stuff make us love Physics!
Being an Indian High School student, I am going through these wonderful lectures to have a better clarity and strong grasp over the concepts. Doing tons and tons of numericals by just remembering the related formulae and direct results and not giving much attention towards why and how, is like eating kgs of edible stuff without acknowledging the nutritional value of those.
What you did 22 years ago, before even I was born, made me certain of getting a great score on the University Entrance Exam which is about in 37 days. Thanks a lot, sir Walter Lewin!
That's awesome!
I started learning physics again because it is a requirement before picking an engineering field for uni, and I had already kind of had my mind set on programming and computer sciences. But watching these videos and just getting to read a physics book on my own terms without someone trying to force equations down my throat, I've become in every sense of the word addicted to physics. I am spending anywhere between 6-8 hours a day now, if not doing assignments, atleast listening to your lectures, and it's not to pass some test or get some grade, but because it's just fun. Pretty cool how all it can take is one persons enthusiasm to spark a love for something. I'm going to choose a major in physics, and you're part of the reason why. Thanks.
I am loving these lectures. Great Stuff! Thanks for all the help you have given me this semester. I'm even showing your videos to my kids and they love them and could even explain kinda what you were talking about after watching.
GREAT!
Queria ter um professor com essa didática e paixão aqui no Brasil
Sir iam INDIA were we have plenty of persons who have a extreme knowledge but no one is residing in india to explain as effective as you with all the demonstrations which made us to learn more quickly and store it memory effectively.THANK YOU a lot sir,for these classes
What a very special gift you give to us ! You add loads of context to the theoretical knowledge that remains long after graduating. I always wondered what use it would ever be to me. And now... I see the beauty of it all !
Thank you so much ! You made me
💚 physics !
My pleasure!
thank you prof.i am from Nepal studying engineering and it is one of the best lecture I ever had lot of practical knowledge
:)
Your lectures are actually helping me like physics. Physics at university has been pretty difficult for me, but your lectures actually makes it really easy to understand, which has never been the case before. Just have this last physics class left and then I graduate! Wish me luck.
I learned a lot from this lecture. I cannot put into words how grateful I am. Thank you so much Prof. Walter.
You are very welcome
my daughter really likes your lectures ...they helped her alot. earlier physics was like a puzzle that is now being solved by your help. thankyou soo much!
+SHRIKRISHAN YADAV excellent
Wow! The way you teaches is awesome. I am from India. In Indian schools we are taught these concepts in class 12th and very fast. Much of the attention is given to the problem solving part. Most of the students solve problems but they didn't know the concept behind. Still the Indian students are very much hardworking (also due to JEE Advanced, etc). Sir what's your opinion on this ?
Wow, thanks
You are truly an amazing teacher of physics sir.we r very grateful to have ur lectures on CZcams 🙂 thank you so much☺️
:)
I am from Sri lanka .and I learn new concepts from all ur vedios and that's really amazing. HATS OFF for your valuable job . Like to be a student in ur clz !!!!!
I'm currently having Eletromagnetism and Optics as part of my Computer Engeneering course. I'm not into physics at all but your videos make me apreciate it a lot more. You're a very good teacher!
You have many students all around the world and you are the best teacher. Everybody loves you.❤❤❤
Sir I am from India and these physics lecture are very helped me in my jee preparation thank yoy sir for these amazing lectures ☺️☺️☺️☺️ love and respect from India
my gawd Walter, next time I'm depressed I'll remember that such a good man like you lived walked and taught this earth, and feel blessed about it. Thank you for such a lecture.
30 years after my engineering graduate I watch Mr lewin’s lectures just for curiosity not for grades not for a special need for my work in deed learning is pure fun. Kids who had opportunity to attend his class should be damn lucky. He is a treasure
Professor Lewin...I'm a professor also and an Inventor in Mechanical Machines and I love your passion and focus for the field. I believe that one should have the passion that you have to do great things. Thanks for the videos.
+Andrew Amini you are welcome
I've never considered physics as an amazing subject , but now I know why ... Because I've never been taught like this . Thank you so much sir 🙏🙏❤️
Everyone admire Sir Walter Lewin because he is so great. Thankyou sir for teaching in the amazing manner. I would also like to thank the cameramen who had captured the perfect angles for us.
Sir wailter one lecture in which he is hanging from rope and swinging proves that mass has no role in determining the time period of oscillation T= 2*pi*√l/g
One lecture of sir Walter on which he rubs silk rod by cloth was basically meant that charge can be removed from silk rod by rubbing cotton cloth such that now if we take that rod to any neutral body then it will do polarize that body and body will be attracted because distance difference from rod and it will be attracted same experiment like scale attract piece of paper when u rub with your oiled hair.. Remember use those material in which charge can be removed by rubbing don't use wood other things..
Thank you, Mr. Walter Lewin. I had ended up socfusing myself with field really bad. It's all clear now. Really intutive. Cheers.
I want to become a theoretical physicist, this is my last year in high school, then I will start applying for universities abroad (I'm from India FYI). These lectures really help with understanding and getting a firm grasp on the concepts. I really would like to be as good a teacher(if not better than)as you. You teach physics the way it is - "INTERESTING & AMAZING"
:)
If I had one wish, I believe i would certainly consider wishing for ten thousand Walter Lewins to teach the world physics. Imagine what a wonderful world it would be if everyone had a teacher and role model like him. Unfortunately, I was never able to attend a university and receive a proper education, so i have to settle for watching lectures on CZcams and taking free classes on EdX. It must have been great to have the experience of learning physics directly from Professor Lewin. He is an amazing man
I hope I clear my JEE next year from your lectures.
Did you
bhai kitne mile JEE me aapko?
Thanku for these amazing lectures...
Love from India ❤
Profesor, I recently discovered that you have a CZcams Channel that has all these lectures! You are so good on explaining physics, thank you so much for sharing all these to the new generations. I am an Electrical Engineer with a PHd and I am really enjoying how well you explained Electromagnetism! Thanks, thanks thanks!
Students sitting there are attending the most beautiful explanation of nature.....Learning it's way of working from one of the few men nature has bestowed upon with the responsibility of decoding it...I would surely be honored to attend your classes....But it is a dream.....Btw...LOTS OF RESPECT FROM INDIA
SIR....
I finally fell in love with physics , thanks professor 😄
So much fun in learning about physics from the most terrific teacher, I can't stop staring that scarmble egg!
THE TEACHER WE NEED
Thank you sir, I'm a class 12 student from India aspiring to be a scientist/engineer, this definitely helped me revise my school content.
Me too I am in class 12 in India too ☺😁😄😃😀 🇮🇳
An understanding of electrical forces is indispensable for my field of choice, cognitive science.
Thanks to your teaching excellence, I am getting really passionate about the physics of, well everything.
A little mean tbh as I wanted to use physics for electrophysiology and then leave it for a time. Now I might have to learn much more to satisfy my curiosity :)
I actually tried myself to write down your lecture as a whole but it took almost 4 hours per lecture, however ur lectures are quite convincing and full of information with powerful demostration, thanks for such providing such informative lecture online
I once created a cc file for an 8 minutes video. That took me 80 minutes. Thus my ratio was 10 to 1. To create a new cc file of a 50 min lecture would take me about 6 hours.
Love from india 🇮🇳. Your lecture helps me alot in jee preparation
Glad to hear that
Thank you so much for posting this! Great to see people in love with physics. Greeting from Argentina.
Someone ask me one day how they understand physics I say keep calm and watch prof. Walter lewin😘😘😘
:)
First time in my life, I m seeing such a interactive lessons from the god of physics.
You Are Amazing🙏🙏 your ways of teaching are so efficient ! Thank you for sharing this with everyone ! High level education should always be available for everyone🙏❤
:)
Respected Sir,
Who were those two 'men in Black' barging into a room where a great event was being held.
Sincerely,
My humble 'itching' Curiosity
I believe they were reminding a student about his upcoming Fraternity Pledge!
it's look like more serious than that! something like drug sellers deal !? :D
Maybe just to keep the attention on him
@@aashishsoni7428 ahahahaha
it is a dream for me to do a class like that.Wish I was there!
I am from Bangladesh and we can't effort so much in a class. "money cant't buy happiness but money may buy knowledge " 😞
:)
I'm also from Bangladesh :)
Money can't buy knowledge
@@arpitas162 They mean rich people have access to more sources of knowledge. Many children have been born who would have contributed more to Physics than Einstein himself, but they lacked the access to education (either not able to afford it or because of gender/ethnicity/religion).
@@arpitas162 Also you’re watching on a device which costs money.
Sir, your students are really lucky, you made me love physics, which I hated before, all thanks to you:)
Oh my god, thank u so much for these lectures. I knew there would be electric fields but never really had a good intuition and never believed it.....but after seeing those seeds align in that way....it really made me happy...... and as always...*physics works* 👍😊
Excuse me sir, you have an egg on your shirt.
Wowwww I wonder what happened, but thanks for letting me know.
Np. Thx for the great lecture btw.
It is a distinctive, of which the location on the body and not the substance referred to bears the significance. Most of Walter's colleagues have egg on their *faces*, not on their shirts.
ha ha ha
I hope no student in the lecture hall, is hungry.
Sir , how to be a great physicist like you? I am now a BSc physics student from India. 😊
eat yogurt every day but *never on Fridays.* That worked for Einstein and also for me.
@@lecturesbywalterlewin.they9259 oo yeah ! But why not Friday sir ?😅
@@rajdipbandyopadhyay1942 go to a school where physics is taught Don't ask silly questions ^_^
Myself and most other physics teachers I have worked with are perfectly capable of teaching this same material in the same way. Actually most of this is just high school level Physics even though he is teaching it to MIT college students whose parents are paying a fortune in fees.
@@gweilospur5877 Keep in mind that MIT is only a very mediocre University. That's why only 98 people who studied at MIT or who lectured there received a Nobel Prize. *That's very embarrassing.* Luckily you got a much better education.
I am so impressed the way you give glass , I didn't know there is such interesting class that student isn't bored
For the first time ever I've realized the actual science! Thank you for these videos
Previously I was in love with physics now i am in love with you also ,Sir Walter Lewin.
To all viewers :- try watching the oil seed experiment at a speed of 0.25x it's of more fun.
Great teacher there.
+kenny Roberts Thank you
Is this Walter Lewin?
+kenny Roberts Yes I am \\/\//////@lter Lewin. I run this site.
It's an honour Sir
Awesome sir …you just make me so proud tht I m actually going to pursue astrophysics now Thank u sir and immense respect May u live long and be blessed with all you desire
superrrr
I always byhearted physics and for the first time I am understaanding this . HAndsoff to your work.
Massive respect for you Sir from Pakistan. :)
I like your classes alot sir.thank you sir.
sir i am in 10 and enjoy your lectures soo much i decided to try my best to join mit because of you,my dream is to meet u and discuss physics.thank u for inspiring me. i love physics and you
Walter retired like 13-14y ago so you won't find him at MIT anymore... but good luck coming up with the $60k/year that MIT costs.
My professor is from MIT and these were great supplementary lectures for Rutgers Honors Physics course.
i have seen at least 30 of your lectures Sir, which were of course very helpful, and i noticed you wear a fried egg or a banana brooch which is very unique so i want to know what made you do that?
He actually explains it in his book. It's an amazing read and is filled with the same energy his lectures give off.
I want to study in mit.. Its soooo freakin gorgeous !!
Platwn Ace First improve your English.
Grom...Improve your courtesy and manners to an adult level!
Loved your approach and you make students fall in love with physics with all experiments and everything☺
:)
Thank you so much, sir, for these lectures. They are very enjoyable, and I find the way you teach using experiments rather than just formulae to be a breath of fresh air.
Great knowledge and interesting personality 😇you made me love physics even more
28:05 what the hell?
Thanks to this man that my interest in physics has respawned
My pleasure!
I love this guy for his knowledge of his lectures so I won’t be late to get a static charge of electricity in my mind.
Thank you for your wonderful lectures professor sir i am NEET aspirant from india.what to do to crack Physics in NEET sir.
and that how you have fun and study physics at the same time :D!
:)
by the way, does this channel belong to Me Lewin himself?
Yes I am the REAL Walter Lewin and I run this channel.
oh! that's such an honor to be directly contacting you via these comments. I started loving mechanics after watching your online courses and the same is happening here with electricity. Thank you so much!
You are welcome!
Brilliant! I must show these lectures to my daughters. Greetings from TU Delft.
groeten uit Cambridge MA!
Thank you for these wonderful lectures! :)
You're most welcome!
"You can always through induction [and deduction!] test the polarity of your charge."
Eggstraordinary lecture sir:)
am a student from Nigeria...
and our lecturers just give us handouts to read...
watching your videos have given me hope to be among the best.
thanks sir
here in india these guys
never do practical demonstrations
which are highly necessary
for better understanding,
so i utilise your demonstrations
which are so helpful right now
after 6 years sir 🙏🏼
i am going through each of your lectures. i am afraid will this channel be deleted or removed before i finish all your lectures..
I expect to live perhaps another 5 years. In any case, after my death this channel will be continued by the famous Professor Lynn Cominsky who is my former graduate student.
thank you professor , i have no words to thank you!
:)
Lectures by Walter Lewin. They will make you ♥ Physics. ,
I hope after ur death
U can find out what's it like to be in a state of death 😊
I'm jealous but not that much
But I do wanna know what's it like to be "dead"
Lectures by Walter Lewin. They will make you ♥ Physics. I was shocked when I heard you saying death, wish you long life in this great job u have been doing.
Respected Sir,
Who were those two 'men in Black' barging into a room where a great event was being held and did they say.... please...can u tell sir.... :)
Ive always know physics was beautiful, but I've never put my mind into actually taking a look at it. I always thought only astronomy was interesting but it looks like i was wrong. Your influence is also so powerful it reached India, thanks a lot sir.
Best world physics professor I have ever seen❤
19:13 oh! the chalk break
Your explanation is excellent, our school faculty told to watch your videos
Sir anubha here I spoke to you before also I m so die hard fan of urs as a human and as learned knowledgable person I feel being learned keep learning and spreading knowledge is one purpose of life in true sense ..Thank you so much for this illustration U have made this subject all the mroe intriguing physics has always interested me now I m planning for masters in as to physics or quantum physics needed guidance help from u
I cannot guide you as I do not know you. MIT's courses QM1 and QM2 are on my channel. Great lecturers!
28:07 what was that
i don't get it either
