[jjclassjj]

Very enjoyable thank you

[Kricardose]

I am very happy to see the vidoe In addition to the basic concepts of Electromagnetism, a vast variety of interesting topics are covered in this course after you give this

[bebeheuy]

I Love The Video It Can Increase My Knowledge n addition to the basic concepts of Electromagnetism, a vast variety of interesting topics are covered in this course

[Mjhond]

Steady I Really Like This Video In addition to the basic concepts of Electromagnetism, a vast variety of interesting topics are covered in this course: Lightning, Pacemakers, Electric Shock Treatment,

lool bin ein luder

[BeylaKaythin]

I have only seen two videos of him yet, but I have subscribed right away. And I hope that I will finally stop hating physics, but like, NO love it ;)

I love the ideas so much, the thinking, the things you can do with it, but our teacher can do nothing than be angry at us, yell at us, and tell us we aren't doing things right and that physics are SO DAMN HARD! D: This makes me so demotivated, while I once used to love physics...! Thank you, Walter Lewin!

[mdgreg]

Is it Possible to Construct a Motor Using Electric Fields and Not Magnetic Fields?

[BartLouwers]

I wondered why I could understand his English so well... It was because he is apparantly also Dutch :)

[MJsDisciple]

Walter Lewin is awesome!

[harsha205]

i think many teachers kill subjects especially in India by teaching them for exams...i find some of the teachers on youtube really great

[theplayboy92]

@harsha205 I agree, this is a devil for the students who really want to learn physics by loving it. I'm one from West Bengal, and I've felt how terrible the thing is when physics become for exams only.

I hope there are a couple Lewin everywhere, where physics exists. It'll not be a bad comparison if I compare him with Feynmann, said to be the ebst physics teacher of the previous century.

[jelekbang]

A truly dedicated person

[cepulga1]

Beautiful

[abasswis]

Wonderful

[TheOrigHammer]

Thank you for your lectures, I understand all of your lectures as they are very well done actually they are the best and agree with you fully you have harnessed the real problem with educational methods today, and have elimininated that non-sense dictatorship. I really like the fact that you had said " It is not about what you cover but what you uncover") that is true and should be recognized by all educators. Other educators really need to learn from your example.

Thank you!

Eric Broughton.

[dan2kxyz]

Wonderful.

[blinginlike3p0]

his head makes me dizzy

[abhishek0raut]

his awesome

[VictorAndScience]

'Soda is a general tendency' CC <3 Anyways exquisite lecturer.

[frostwow]

yea, salutations.. even his voice is clear, not shaking, thats a big YES!

its a pity, though, that the technicians degraded this video a failure IE. 15FPS - THAT HURTS MY EYES! would have needed 25fps at least

but i know you university guys dont give a sh

[claudiomatex]

why he moves his head like that?

[LedgeG2]

This course sounds amazing <3

[ATIhYdrax]

This man should've stayed in Holland at the Delft University of Technology, so he'd be my direct teacher, that would've kicked major ass

[rocknroll980]

You know what, fuck wind and solar power, magnetism is a good substitute. It isn't expensive like wind/solar power and is FAR more powerful.

[MrWopz]

all you courses are brilliant , i have learn a lot from OCW since it started i would like to extend my extreme gratitude for all i have learnt.

and yes mr Lewin i love physics now, when will you teach us about the flux capacitor?

; )

[tuscanigtv6]

proff lewin rocks...makes electricity n magnetism for me so much easier....thanks alot for these videos..

[tf88888888]

wow....is all i can say 5 stars bravo man bravo

[planetinvader]

We have 4 idiots who disliked this video.

[Mr5CHNELL]

There aren't too many educators that actually "get it". Professor Lewin is one of the few who do. This guy teaches people to understand whats happening rather than just copy down some formulae and repeat over and over til it's memorised. I bet most of his ex-student's could derive the formulae by thinking through the principles involved because they have understood the phenomena behind the math. This is the kind of learning you remember years later when formulae are a fuzzy memory. Great teacher

[thunderdou]

Tous les professeurs devraient prendre exemple sur le Prof. Lewin

Chapeau sir!!!

[mohamed3417]

great professor we need a professor like you sir

[Lifesucksdie123]

he might want to chill on the coffee...

a little

[sandeep88214]

A great man



[mahela1993]

A truly inspiring teacher.. Thank you Prof. Lewin. I get more out of your lectures than I do from any text book I own.

[nuketrooper1]

4:13 - 4:24 is the peak of human eloquence.

[aphididae]

uhh... does walter lewin have parkinsons?

not as an insult, but his head shakes a lot there...

[March6371]

@aphididae - it looks like the tremors that go with Parkinsons. I thought that as well.

[SaM52461]

@March6371

It's from shocking himself with the tesla coil and other instruments in his lectures,

50k, 150k, 300k+ volts even at low amps might have had an effect on him

[EasternMerchant]

@March6371 This is why we need to heavily document (video, pdf's, etc.) the great works of these professors because at this level of education, such professors are simply irreplaceable because, as of yet, death is still not an option for the human body. Lewin might or might not have much longer on this earth. In other words, it would be a travesty not to capture the Golden Age of Education!

[hepzibhadavid12]

I am a physics teacher surely This talk was inspiring.Thanx.

[boeing747200lr]

Hats off to you sir!

[Shalimarfemme]

Thank you for making your lectures public. Prof. Lewin is astounding and should be a national treasure.

[Xxd3cayxX]

Wow, this man is incredibly brilliant. I am honored to listen to him speak about electricity and magnetism :)

[faisal798]

MIT lecture in youtube absolutely stunning

[AmirasCareless]

What a remarkable men, I've never seen more contributed person in teaching then Walter Lewin.

[xbeerxpressurex]

This guy is a fuckin genius

[LFZ15]

he is such an unbelievably good teacher... really did make me love physics :3

[7kholoud]

How come he's very good at it ??

May he teach our professor as well ,, I think it'll be great if professors attended as well

[bloomingdedalus]

I am ecstatic to have discovered Prof. Lewin's lectures - thank you MIT for providing such superb content. This professor is a great asset to your institution - he is brilliant, funny, and very clear. Had I not digressed into the humanities when I exited High School I may have found myself in his class - but - alas - there is no accounting for what this world renders us. Some grow up believing in a grand apocalypse - and nothing will rob a child of a future quicker.

[mathboy007]

Dear Sir, Your method of conveying is absolutely fantastic. Although I'm not a student with Physics major. But when i saw your video on MIT-World, i liked it very much and downloaded Electricity and Magnetism 8.02 course. Thank you very much for your time.

[oruizmagua]

I wish for one day to have a professor like this at my University. They are good science professors at FIU but none as e spectacular as Mr. Lewis. I like the part where he says " The relevant thing is not to cover the material but to uncover it " Makes a lot of sense plus help student to develop passion for general science, specially physics and math...

[taekyung1000]

yes sir. he's really smart.,

[famousfakirr]

yes he is very good. extremely motivated. impressive!!. i wish i had such teachers in my university.

[0ElectroMad0]

Today I found his lectures, watched only one & I can say he is AMAZING, AWESOME, GREAT... thank you prof. Walter

[zim01001]

Awesome teacher, I have not seen him in person, but following MIT lectures online!

[mst7eel]

I wish that this guy was my teacher.. great teacher with a great passion

my lecturer is crapy more than u can imagine & the biggest problem is he is teaching me the basics of electricity !!!

[yahoo12316]

Hello Mr. Walter Lewin. I have never actually been in one of your lectures but I have seen all of your lectures on youtube. eventhough I don't know you, I THINK YOU ARE THE BEST PHYSICS TEACHER ON THE PLANET. I would have been so happy if my physics teacher was as passionate and smart teacher as you. All your lectures has allowed me to see the beauty of physics and I am sure you know this (your a physicsist) ONCE YOU GET INTO PHYSICS, YOU CAN'T GET OUT. THANK YOU FOR HELPING ME LOVE PHYSICS!!!!!

[JanColdwater]

He is right! I will never look at a rainbow the same again! Thanks Professor Lewin! These online free lectures are great for us 40 year old mothers too! If a child asks about a rainbow, I can give them an answer! In fact, I can't wait for summer to come to get out the garden hose and try to explain it like Professor Lewin did.

[JanColdwater]

I watch his lecture on Rainbows. I am not a very intellectual individual but I found it very interesting and was able to follow it for the most part.

[pavzirka]

there are three types of scince professors in the world.

The brilliant scientists who don't know jack about teaching but kick ass at reaserch.

The ones who suck at research but can teach you everything you can possibly need to know.

And a rare type, like Lewin, who can do both.

[gomunkul]

@pavzirka there is also a 4th kind of Prof.: the ones who can't do either !

and I do know some 4the kind Prof.... ;)

[panasencoaram]

@pavzirka

asskisser

[NeSy12]

@pavzirka How could you forget the fourth type... Those who can't do either.

[pforzen93]

@pavzirka i find it funny how every singe lecture video on youtube by MIT and such attracts lots of comments like yours. sort of like, OMG you are so awesome and my teacher sucks! 10 seconds of this video gives me more info that all the lessons i took in my life! yeah, every single professor on youtube is a "rare" type  and those in real life all suck.

[skyfaze]

its rare to find a good physics proff like him!

[weyrauch]

Walter Lewin is a good example of the rare combination of great didactic abilities combined with an equally great professional knowledge - if you ever run across a teacher like this one, make sure you grab him and drag him to a clone laboratory to conserve him for the posterity... :D

[aphionorman]

great teacher.... i salute you sir

[criticalzen]

So fascinating! Professor Lewin is amazing with his philosophy of teaching and his real life correlation.

[Mickch200]

thank you  Prof. Lewin!

[TheWiepi]

If every teacher was like him, everybody would love school/university.

Good teaching personal is soooo rare :/

[nkgr01]

4:17 .... What else can be said about this teacher? Thank you very much Prof. Lewin!

[leviterande]

is this for collage or high school

[Arycke]

This is MIT :-P i.e. an ivy league university: college.

[RosecrantzTheSpy]

@Arycke Not ivy league, not that ivy league makes a school good.

[Arycke]

@ RosecrantzTheSpy thanks :-) Also, for what it's worth, it's just as good or better than some of the ivy league universities in Mathematics (which is my major so that's really all that pertains to me), as it is in the top 5 Math Universities :-D And this is true, just because the school is ivy league doesn't make it good.

[Bazz7999]

he looks like woody allen a little......man knows his stuff though!!!!!!!!

[armand009]

MIT learning for FREE?? that is great, knowledge belongs to everyone in the world, thank you for the videos. He sounds like a great professor.

[VeXorian1337]

By far one of the most inspiring and interesting EE lecture series I've ever seen! I've learned so much just from these videos! I'll gladly donate for more! 5/5

[BobDpirate2]

He reminds me of Jumping George Yevik... My physics teacher at stevens:)

[Hantroxy]

What he spoke from 4:12 is very correct and very right. Great line:"what counts is not what you cover,

what counts is what you uncover"

[cdltpx]

I love what MIT students did with common everyday parts of today to produce RE systems in thirld world countries. You can go to a auto parts yard pull some parts and build a system that would provide electricity to a person that has none this can do so much to promote true equality in this world and may even be the link to eliminating poverty in some places. I would love to be completely off the grid I think I will be some day. The systems can eliminate deforrestation in some areas with oldjunk.

[Cloxxki]

Not because we born in the same country, amd I will admit to never really having had much college, but this guy is the first I would respectfully call "professor". It really is about teaching, and the way you do it. Not spreading your business card for the last 40 years of your life, after you've did a bit of butt kicking in various institutes to be allowed to call yourself a prof. I'm super lazy, but might just follow all he videotaped, for my ultimate goal to irigate the Sahara.

[paulinusp]

seems like professor lewin got parkinson...

[Leichewow]

It's probably essential tremor. It's benign and is usually worse in the morning, Stress or hunger makes it worse.

[Bluesisawesome]

This man rocks! Physics Star! God Bless You and all of us!

[mickch199]

what the MIT does here, that's great!

thank you that it's possible to participate in your fantastic lectures from germany

[lenihaw]

I so have to experience at least one of your lectures first hand! Professor Lewin is the god of physics. ha.

[tigernov6]

Why is he shaking?

[krw667]

i think it's a medical issue.

[igoronline]

looks like parkingson's or the "extrapiramidal effects" one might get from high doses of antipsicotics.

[IceFritzLanger]

Thank you MIT, feel sorry that I can't give you money, but those videos are like an utopia becoming true :

One can learn what he-she want without any material problems.

[myuhh]

Thank You MIT for posting lecture videos to expand my knowledge for Physics for engineer majors

[soulreaverdoug]

this should be in spanish too, please make a translation program for those who want to help to translate this great videos just like wikipedia, this should be universal

[budd8y]

Ya how about fuck no, if you want to understand what his saying learn english or fuck off. Dont get mad spanish isnt a special language and people shouldnt take time to translate this program.

[soulreaverdoug]

hey i just wonder why not you neo-nazy crap i can speak english how many languages do you know huh do you think english to be the universal fucking language or something, go to hell yankee-shity asshole

[budd8y]

I speak 7 languages spanish is one of them, dont be a douchebag. Dont speak when you dont know shit

[soulreaverdoug]

ahahahahhaha this just hilarious....

why not 6 laguages or 8 why seven you could have another made up historie please don´t make me laugh cuentame una de vaqueros pendejo

[budd8y]

You Salvadorian fagget first learn how to insult someone before you start talking shit. I know its hard for you to imagine that there is more than two languages in the world so its okay that your surprised that I can speak 7. Also if you want to talk shit do it in person its easy to be tuff behind the computer. Once youre ready to talk shit to my face let me know if youre not then shut the fuck up.

[soulreaverdoug]

ahahah you really went to my channel im flattered, fuck you, i speak 4 languages it took me 20 years, what you say it´s just stupid c´mon get a taste of reality. Haben Sie Verständnis, wenn ich sage, Verpisst dich

[renderrob]

You are a very poor example of a human being, and of an English speaking individual. The man simply expressed a desire for a "translation program". Your insults were uncalled for. If you don't have anything nice to say, don't say anything at all.

[shinet]

Sure you speak 7 languages....

[shinet]

Learn grammar and punctuation. It's part of English.

[IceFritzLanger]

I m french and I don't complain.

They are very gratefull to let you watch this course ( and they teach in English in MIT )

But you could be a great man, if you put subtitles on it .

Go on, Man, sub it like a pro :)

[lenihaw]

but english is the universal language...

[snapshots69]

No math is a universal language, English is just common.

[brunojl2]

Math is not a language. We use languages to talk about mathematics. Mathematics is so much more than just a language!

[sobman]

I would love to attend and just learn things like this, from people like this guy.

Even though i'd never be involved with physics, or magnetism in general, i'd just like to learn there.

[MyOverflow]

Yeah. What I meant, though, was getting a higher output of energy than input. i.e. Electromagnetic "free energy" devices, where they input electricity and expect a higher output of electricity.

[thecapone45]

mit seems so interesting, one quetion though for the ones that go or went there:

do they teach courses on electronics? like thats what i want a class on, electronics, i get the school is about technology, but i dont know what fields in technology, so if anyone knows, PLEASE help me out

[HikaruYami]

I do think 8.02 would be fun, but I'll be taking the harder, more normal-lecture-like version, 8.022.

[dasgregorian]

I really like this guy's teaching style. If I could afford MIT, I'd love to take the class just for personal enrichment.

"subject matter covered" isn't as important as "UNDERSTANDING!"

I'd really love to see some of those motors.

[iridethewave]

MIT is extremely easy to afford. Three of my friends, whose names I'll keep confidential, got accepted to MIT. All of them were of median income. When they found out the grant packages they were awarded from both MIT and the University of Texas (which is VERY inexpensive for in state students) they actually found out that MIT was cheaper for them to attend than the local state university!

MIT gives amazing aid packages, if you can get accepted, they give you the means to go.

[AirwarriorX2]

But subject matter can also help you understand . what that is . =) that just me sir.

[AYOitseny]

I love this video.

Physics rocks!!!

[MyOverflow]

Thanks MIT, now whenever a bunch of "free energy" nuts show up, I can just link them here. ;)

Haha why is it when I see this video, I expect him to yell out "1.21 Gigawatts! Great Scott!"

[diazluisdiaz]

hahahah good one

[trader891]

Agree on the "free energy nuts"!!

[tivrfoa]

very beauty and spontaneous intro! I agree with him. The best way to teach (and learn) is mix theory with practical exercises.

[hemsley12345]

2002 great year

[davidboy07]

this guy is awesome, i never taught teachers could be like this one. he has to be dutch.

[mike2601]

Top class - thanks

[fasflink]

respect

[amthewillow]

Prof Lewin - am back in my home country Kenya and I still remember to check the second rainbow when I see one!!!

I recently saw one over Mt. Kilimanjaro while I was flying. You're passionate and thanks for being a great prof!

[jerms246]

MIT is the best f*king school EVER!!

[Lucky1Lucky1]

Thank you professor and MIT! I went through all of your 8.02 and 8.03 lectures, and they were just excellent. It really was a joy to watch your lecture videos. Please keep up the good work. BTW, is there any other lectures other than 8.01, which I am currently viewing, from Prof. Lewin?

[S201676]

I do not believe so; I believe Professor Lewin did other classes, but it appears that only the three most basic physics classes were extensively recorded.

[d0nunit]

why dont you teach at my school

I was really scared taking physics 2, but after watching this video, I think I can do good,

but if you see my professor at accd college nvc

he sucks big time..

[Mastikator]

Thank you MIT! I love science and education. I'm so excited about watching this series.

[eidoidf]

does someone know if this course is the highest level of Electricity and Magnetism in MIT?

[HOTAZNGRL123]

theres more... this is just a intro

[eidoidf]

I meant: this material is probably being taught in some kind of levels

like one kind of engineers need one level and others need other level.

is this the highest(hardest) one?

[S201676]

Every student must take 8.02 or the harder 8.022. Those in physics go on to many more classes covering all branches of physics.

[alxms10]

do you have any lectures on soil mechanics or fluid mechanics please?!

and it would be appreciated

[footballover01]

my god i love MIT, how generous is this?, to give ur knowledge to every one, this is hw knowledge should be shared, the Prof. is out of the question

all together AMAZING!!!

[1978rm125]

hey anyone that goes there i need to ask you some questions thanks! im planning on going there for electrical engineering

[youali299]

thank you professor you are my hobby now is to listen to your lectures

[davedefran]

I never thought that I could have a favorite professor having never been in a university, let alone having one in 5:46 after a small introduction on youtube!

I'm so excited to have the oppertunity to watch all of these lectures!

[CarsNsongS]

I wish my prof of physics is just half as gd as u!!!

[DrOidwaker]

He has got to be one of the absolute best physics professors in the world.

[jerms246]

--MIT--

Best School Ever

[NUFC251081]

Great stuff

[bboymarcel]

master thank you I KNOW WE ARE 100% CONDUCTIVE ELECTRICITY ....I can influence electric street lights and use telepathy and predict future ...please tell me how I influence street lamps?? It started when I became avegetarian and after I found out that time doesnt exist ...

[kdawgfoeva]

U r an amazing person

[julebakst]

Thanks professor! Keep up the GREAT work!

[12creations]

I think that this is the most amazing thing I have ever seen... a major University giving "online courses" for free! I absolutely love it and the lectures are so fascinating! Now if only they gave out some sort of exams that you could test yourself at, that would be perfect. But I'm sure I will be able to find a couple online. I am going to donate. Thank you, MIT.

[djKINGjohn]

Search Google with "ocw walter lewin 8.02 lectures" and click on first result.

On the left there are links to add to the online course, including four exams.

[12creations]

Awesome! Thank you!

[yomomtubes2]

Exactly! The last minute or so is precisely the point.

[firstlk420]

good stuff

[ignilc]

this guy is eather severly stoned or suffers of an agressive form of mental retardation

[Aoitetsugakusha]

There's a semantic error in your sentence.

You mistyped 'this guy' as the subject of your sentence where you should have put 'I' as the subject.

I know quite a few professors who could do with taking a page out of 'this guy's' book.

[DmitryJemeljanov]

Good words!

I haven't seen any of his lectures yet, but i hope they will be more complicated and interesting, than MIT maths course... ;-)

[avecvagars]

;) he used to work a lot with Electricity

[ownedzik]

Does he have Parkinson? Omg nooo... :(

[eddiethemetalgod]

this video really helped me a lot in the understanding Maxwells equations...i hope u keep uploading such videos here

[ijustinsane]

"And they will always think of me when they see a rainbow. And in fact sometimes 20 or 30 years after a lecture, they send me still pictures. and they say, "Professor Lewin, I saw a rainbow, and I thought of you and here is a picture." And the interesting thing is, they sometimes send me a picture which is not even a rainbow, which is a glory; but that doesn't matter. What it shows is, that I have succeeded in making them love physics. -WHAT!? How do some @!&$in ppl not know a rainbow's image?

[sy1234]

Wait a second. Not all educators should make people love physics.

I don't want an English professor making me love physics.

[boaarmpit]

He has the right philosophy.  I really enjoyed his videos.

[yienmei5]

he know he can do something different,yes he did

[nadademamaditas]

I'm from mexico. You have no idea how I appreciate OCW. Thanks.

[killabilla]

my electromagnetism teacher suck...damn i went to 3 of his lectures

[boxa888]

i have recreated nikola teslas one wire transmission which goes against the closed circuit system. its a very important concept and eventually leads to his earth wireless system 100 yrs ago. energy was even sent faster than light at some points. i am one step closer. please watch its important and should be apart of common physics!

[agush22]

We in Mexico love you

[wingtsunnineoeight]

this guy knows, this is gret lots of the best lectures in the world ...

[gmeatdaddy]

well, Why not tell about ALL of Maxwell's Equations?,And why were some of the Equations discarded?

-gmeatdaddy
