  • You don't have to use hair gel anymore. Electricity works just fine.

  • “I will show you whether you like it or not, Physics is beautiful."

    This is enough for him to be my role model. I wish someday as a professor I could say that to my students.

  • Steady I Really Like This Video Electric Charges Historical) Polarization Electric Force Coulomb's Law

  • Gee, he is cooler than Sheldon Cooper!

  • This guy is a wizard with a chalkboard. Look at that circle, the dotted lines... magic.

  • also. How the fuck could someone dislike this ? It puzzles me

  • How do I not know any of this ? The only thing they teach me is to fucking solve differential equations and shit.

  • science ftw

  • You, Sir, are a rockstar.

    It´s natural to be cool if you have a band

    It´s outstanding to be cool if you teach physics.

  • Imagine if Simon was black... beating a black guy called Simon is not OK!

  • Around 24:20 reminds me of Patton's slapping incident... funny!

  • 19 people can't think, even with electricity

  • i didnt get to see the light :(

  • awesome

  • he makes me proud being a dutchmen

  • Heheh i got a laugh out of him beating (charging) the student. He's a really good professor!!

  • Great teacher makes the subject understandable. Not easy, but you're not fighting to figure out what they're saying. Many of my profs had never taught the material before, were fighting to get research money, and didn't have the time to properly prepare lectures. If they taught a series, that would be 25-30 hrs of lecture per class. That means they needed MANY more hrs to prepare their lecture. They simple didn't have the time, so the lectures in many cases were very bad. Students got shafted.

  • I was in this class. Brings back memories. Walter Lewin was the best.

  • lol bin aus hamburg

  • Omigosh.... wow.... not a single one of the students asked a question.. does this mean they understood everything the professor said? Gah, I feel stupid.. but the teacher did make most of it entertaining and easy to understand, so I didn't have much problems either, but there was the occasional question i wanted to make every now and then.... MIT TEACHER ARE WIN

  • @SandJDavies maybe they were told not to for the recording?????????? Gah

  • seems fundamental for an MIT course...

  • Ahh 240p, the bane of my existence.. Great instructor and content though..

  • wow.... this was an awe-inspiring class.... and so funny....

    congrats to this teacher... i want to see more of your classes....

    congrats again from Guadalajara Mexico... I want to attend MIT one day..!

  • The legend that is Walter Lewin. The inspiration behind Yoker University.

  • this is so beautiful...i think i'm going to cry

  • DID ANYBODY SEE THE LIGHT OR SPARK which was supposed to go off at 25:20 - I wish it had a high quality camera :(

  • What book do they use here?

  • 17 people can't think, even with electricity.

  • @templar19 19 now

  • @templar19 your comment is soooo fucking lame and cliche get a life

  • @nomanissafe Uh-oh...another one!

  • hmm..convincing..

  • this is really a great teacher for physics :D want to attend one of his lecture ^^

  • Fucking magnets, this is how they work

  • @kalz1991 .why they work

  • Cours magistral

  • This guy is an absolute class act.

  • wow his dash lines.... wow

  • Great Scott!

  • His dashline drawing is amazing.

  • Excellent teacher!!

  • Walter Lewis is a Dutchman. For some reason no one in Holland has ever heard of this man.

  • @Guardgriffin well, he was on dutch TV one day and he did a lecture here at his Alma mater.

  • We study this in 11th grade.

  • Indians use youtube to become physicists and engineers, that means no Financial aid loans......................BRI­LLIANT!!!!

  • pitty that low defin of video ((

  • okokok

  • he's good at drawing dotted lines sounds clean

    

  • Magnificent!

  • Questa lezione è stata fantastica, mi piacerebbe studiare all' MIT!!!! Thanks for this lesson from Italy!!!

  • Audiences

    This video is most popular with:

    Gender Age

    Male 45-54

    Male 35-44

    Male 25-34

    Please, women, go and cook something.

  • Epic!

  • What I wanna know is:

    How does one draw a broken line the way the professor does?

    Hm?

  • PROFESOR WALTER LEWIN GRACIAS!, THANK YOU PROFESOR (WL)

  • Thank you for this amazing videos!!!! From Technion, Israel.

  • A high-school student trying to learn further than what's taught in school? These professional-styled lectures from renowned professors are better than getting a book and reading it which can boggle your mind

  • he dutch? i think i recognize the accent i used to have...

  • which gas was filled in the ballons ?

    they are easily charged

  • @madhukumareee Helium

  • The people in the audience yawning make me sad, kids get to learn from a guy like this at MIT and they don't pay attention.

  • @Plecebo1996 Whats your problem? The kids are obviously paying attention. Yawning is a natural reaction, just because I yawn in class doesnt mean that class is boring. Its just a stereotypical assumption.

  • if not, dont go around doing experiments,failing them and then pretending to have proven something and then call your self a professor.

  • @f0revern0ty0urs2 You clearly don't understand the concept of a nonconductor. The fact that his experiment "failed" helped to articulate the difference between conductors and nonconductors, which was part of the experiment. So, this apparent "failure" is actually 100% congruent with what he's lecturing on, and illustrates his point perfectly. This is elementary simple, sorry you can't keep up with basic lexical definitions.

  • @vonbryce actually,i do understand the concept,i only wish you could understand my objection,

    Im against his attitude that by failing an experiment he has delivered enough evidence to prove his point,even though as u said it is related to what he is saying.His aproach is unscientific.

    Another thing,he believes that by touching the baloon he has charged it,later he tries to discharge it through his body to the ground by touching it again.It makes no sense,if his body was such a good conductor...

  • @vonbryce ...he would not have charged the balloon in the 1st place.In this case he is putting up a show,circus,not a science.

  • @f0revern0ty0urs2 The human body is a good conductor, yes, BUT it is often insulated. There's a 99% chance that he's wearing rubber soled shoes, he's not a conductor, he's an insulator. That is why he charged the balloon by touching it - he had a net charge on his body because he was not grounded, and this charge transferred to the balloon. However, you say he tries to "discharge it" by touching it, but like I said, he is not grounded, so he is not discharging it but equalizing the charges.

  • @f0revern0ty0urs2 In order to discharge the balloon through his body, as you assume should've happened if the human body is a good conductor, he needs to be grounded. Thus, if he had taken off his shoes (probably socks too) and then touched the balloon, the charge WOULD have been able to go to ground, would've conducted itself through his body. As he demonstrated it, the charge is conducted into his body & equal between the objects, but it ENDS at his shoes, and cannot go to ground.

  • @f0revern0ty0urs2 Once again, nothing in this video is unscientific or goes against the facts that he's presenting. You are misunderstanding some of the concepts, and I think that your English comprehension skills are muddling your confusion. I don't think that you're parsing his English correctly, AND I don't think you're parsing the science correctly, so your confusion is two-fold.

    I recommend that you work on your English fluency before you try to talk shit on an MIT Professor.

  • ok,i already subscribed,but that failed demonstration at 17:00-18:10 is nothing logical nor scientific,its like something one would encounter when visiting fortune teller,

    and at 18:00 he is basically saying,"ok,my previous experiment just failed,but that is because I contaminated the experiment and that even proves my new point to be valid."I'm not buying it .

    Somebody that smart must be able to figure out how to discharge orange balloon.

  • At 3:57 how did he make that noise and the dashed lines?

  • "And you could not even think without electricity, though I realize even with that some of you may have a problem with that." LOL

  • Like this if you're from PSU and are watching this in a desperate attempt to learn E&M

    

  • @gridironkid56 iowa, but i'm in the same situation haha. can't wait till we play you guys again in a few weeks.

  • @gridironkid56 iowa, but i'm in the same situation haha. can't wait till we play you guys again in a few weeks.

  • i have to say i thought the size of the atom was 10^-10m and the nucleus was 10^-15m

  • I wish there was a better video quality, great experience anyways !

  • when you know your heart is light ~ electric is the love - Stylo by Gorillaz

  • This sounds a bit like a Dutch accent, right?

  • In the first 15 mins. what force actually makes the conductive balloon move toward the glass rod when it is the FREE electrons supposedly moving first, then the stationary electrons moving to one side of the atom, which would make it act like the non-conductive balloon. I guess the question is, is there an eddy effect in play, or a difference in the two movements, between the two types of electricity?

    Also, I assume that the two types are positive charge and negative charge, is this correct?

  • Who heard him say 'Flesh light' at 25:00?

  • yes, start at the basics and get them down....progression.

  • you could not see without electricity, your heart would not even beat without electricity, and you could not even think without electricity. Thought I do realize that, even WITH the electricity, some of you maybe have a problem with that.--- one of my fav things he said so far

  • Walter Lewin one of the greatest professors of all time... Wonderful makes it easy to learn... Thank you for your time sir...

  • OMG THIS IS EXCELLENT AND THE SUBS IN SPANISH GREATT THAX A LOT!!!!!!!!

  • Excellent

    

  • 13 disliked? Who the hell are you? Losers, study Arts instead!

  • @oliveiravit

    yes, crap like art history and creative writing!! Ridiculous

  • @oliveiravit aw no man cmn i do both and i enjoy them both :C

  • @oliveiravit Levin has a Liberal Arts degree to teach. Furthermore, Liberal Art majors are the main support for the science and allow science to be communicated to the masses: through language (humanities/english/writing/jo­urnalism degrees), public policy (political science, history, law), learning (teachers) and entertainment (film, writing, music) and don't forget that science, especially physics, would not exist without Math, another Arts degree. You could not explain science without arts.

  • @oliveiravit

    By the way, what's wrong in studying arts ?

  • @CanadianIndian88 its for softies

    

  • @l0lxlllxl0l

    I disagree. If you like something, you should do it. Whether it be Arts or Science or Mathematics or Engg...

  • @CanadianIndian88 i agree but in my opinion people are created with like triats to their desired profession, most of the time,and often times what you are interested in effects the person you are.

  • @l0lxlllxl0l

    Let's just say...sometimes there are no REAL DEGREE's which are offered which interest me...

  • @CanadianIndian88 yeah dude i agree with that

  • Is that an actual university level class? I mean seriously... the level he teaches is what you learn at high school.

    When I hear him saying "We will see if there is any voltage, even though we haven't learnt about that yet", I do wonder why it's so hard to get into?...

  • @upsilone19 Check out the rest of the lectures in this class.

  • @csmcmillion I did... And I still maintain that anyone is able to do this...

    Perhaps this is just the freshers year though. Maybe it gets harder later.

  • @upsilone19 Not people who haven't had the math. And I'm pretty sure this girl couldn't do this...

  • i am from Recife in Brazil, south america, i wanted to know tho, why is it that, that all these smart people like that, got to have these hairs does ...

    does he want to resemble Einstein?

  • The introduction was creepy lol.

  • Amazing...

  • this. is. awesome

    p riot

  • Is there any free PDF book (s) of Electricity and Magnetism to follow all this lectures? Any recommendation?

  • I LIKE TOOOOOOOOOOOOOOOOOO UR LECTURES SIR

  • One of my favourite lecturers of all time

  •  I envy these students!

  • 13 people don't like physics

  • @jaipipor I bet 80% of the population doesn't like physics. 13 people are sabotaging knowledge by disliking this free content.

  • (L)

  • i appreciate that he uses big chalk and that he doesn't write a lot. it really bothers me when professors cram 200 word paragraphs into the board making it hard for even the students sitting up front to read.

  • Spanish translation courtesy of Universidad CAECE Mar del Plata

    POR FAVOR!!!!! mas de vuestras excelentes traducciones!!!!!!!!!!!!!!!!!!­!!!!!!!!!!!!!

  • My favorite part is seeing the number of views dwindle as the lectures progress

  • Am I the only one annoyed by the yawning students?

    Such an interesting lecture done with passion and intellect and their faces still show boredom? Are you kidding me? I would give quite a lot to be in their place.

  • @S0chan It really is interesting but it is still basic physics and they probably knew all its content before attempting the lecture.

  • @Markkxify A fair point.

  • very interesting!

  • how does he do dotted lines so fast?

  • @inveng Drag the chalk with the face flat on the board.

  • mind blowing teacher just like sunil gupta sir(phy bansal classes)

  • This is.....his a great teacher.

  • look at the map of the views, INDIAAAA

  • @marts1233 hahahaha indians like physics i guess xD

  • jai hind

  • @marts1233 lol

  • @marts1233 Thats very interesting- I never thought to even look at the stats for a video..ty :)

  • @marts1233 and your point is?

  • @pforzen93 maybe that the Indians like physics?? eeeasy

  • @marts1233 That just makes me jealous! WHERE AM I?

  • wow no wonder MIT is soo appraised...students get most of the credit for the school being that great...but the professors and teaching style plays such a big role

  • Such an amazing teacher :)

  • I wish our professors were like this guy. Our professors get straight into the math and derivations, which we can figure out on our own. They don't seem to care about learning, but rather on testing.

  • Amazing, simply amazing! 

  • damn  i love physics

  • woah..nice....i wanna study under you :)

  • am avut o spuriza foarte placuta cand am vazut ca are subtitrare si in limba romana

  • I like the way he teach  :)

  • legend

  • this is a teacher.

  • These lectures are addicting. I started on this one and before i knew it the course was over with. I had previously taken E&M a couple yrs. ago, but these lectures are a nice refresher and interesting to follow. Im thinking about watching 8.01 newtonian mechanics now for fun. Its almost like watching a sitcom tv show.

  • I would have thought that MIT would have more State of the Art equipment for teaching; Transparency Kits they had in the Sixties as State of the Art.

  • You actual legend :D you're going to help me ace first year. Thanks so much.

  • The new Richard Feynman!

  • thx for upload :)

  • how did he do that thing with the chalk around min 3?!

  • he sounds dutch. because my chem teacher is dutch and he sounds just like him

  • @AlexsEscape

    Definately

  • i have an idea for gravity in space, can someone let me know if this is possible or not: "WARNING!" iam not school educated so be patient with me.

  • @angel2rx What is your idea?

  • @angel2rx There is gravity in space. Newton's law, Fg = Gm1m2/r ^2 states any two bodies of mass have an attraction force to each other. Therefore, there is gravity in space because the universe is full of bodies of mass. IE, the Sun and the Moon.

  • @angel2rx There is gravity in space. Newton's law, Fg = Gm1m2/r ^2 states any two bodies of mass have an attraction force to each other. Therefore, there is gravity in space because the universe is full of bodies of mass. IE, the Sun and the Moon.

  • @Barthayn: WOW, for a minute there i thought you where ganna get all .. never mind... am talking about gravity in their space crafts or the I.S.S, it must take W-A-Y to long to get things done up there.

  • yes yes, and the vector can be seen by spherical ways crossing the opposing wave. prove of core heating in earth and on our bodies. we do notice in these times.

    see nasa for proof of said wave of magnetic vibration.

  • And now, what I am going to do to you, Simon, is beat you with cat fur.

    hahaha!

  • Love Walter lewin 

  • That why MIT is best.....though i cann't afford it

  • @maanee05 yeah...that's true....It's so hard friend :) but try! you can do it

  • MIT made the PSSC Physics book, which no one can really understand, and then they have Walter Lewin who teaches the exact same stuff, but he's awesome.

  • Electricity and magnitism has nothing whatsoever to do with each other. What an assclown this professor is! Also, electrons are just another word for neutron.

  • @timotsius1 WRONG! and WRONG! a electron is a subatomic particle with a negative electric charge. neutron is a subatomic particle with no net electric charge and magnetism is a magnetic field and a magnetic field is a field of force produced by moving electric charges

  • @jorreerroj LOL

  • @timotsius1 you might as well say the sun is another word for the moon.

  • @timotsius1 Mother of God, what the fuck are you doing here? Electrons are another word for neutron? You're way lost man, I would explain everything to you but unfortunately I'm a mexican guy and my english is not so good to explain a dumbass like you. BTW, this is a good professor, today I saw about electric potential in class.

  • @tengohambre2: WOW! you don't have to be an A-hole. if someone wants to learn, who are you to tell them not to try. get over yourself.

  • @angel2rx Do you think he really wants to learn? Calling the professor "assclown"? Come on dude xD, don't be so gay!

  • @tengohambre2: am bad, i didn't even read his comment. i think the professor's a hottie,smart with a touch of naughtyness to him, niccccee.

  • minute 16.56, we have christiano ronaldo in the house. hahaha

  • @aimantuantd loool i thought the same thing - i was like he does remind a bit of cristiano ronaldo..

  • i wish i had a teacher like him ^_^

  • i was learning about protons and neutrons and bla bla bla... in school when i was 13-14 yo i POLNAD

  • @osterhoutalex Don't give me this proton shit. I am talking electrcity and magnetism, not chemistry. you want to talk chemistry tell me about what happens in a wet cell or battery, and tell me what a potential really is. that is how chemistry works.

  • In physics, potential energy is the energy stored in a body or in a system due to its position in a force field or due to its configuration. Potential energy exists when a force acts upon an object that tends to restore it to a lower energy configuration. This force is often called a restoring force. For example, when a spring is stretched to the left, it exerts a force to the right so as to return to its original, unstretched position.

  • @osterhoutalex Friends don't let friends get trolled.

  • OMG Treasure.
