Lec 6 | MIT 8.02 Electricity and Magnetism, Spring 2002

[Pdy18]

45:20 getting something for your 27k tuition haha

[Orionum]

Thanks

[WannaBeAnEE]

Does anyone else watch this in a room with people without headphones and enjoy the looks on people face like "what the hell does any of that mean!?" 

[hmfmi]

I'm enjoying these lectures.

I've always described the smell in the air during or after a thunderstorm as "an electrical smell" or "electricity in the air" and when the person can't relate, I simply say "it's hard to describe" lol. But I suppose that's true for all scents when talking to someone who's never experienced the same thing... Anyway, I can now just simply tell them, "it's ozone"... lol

[santoyrayado]

at about 2:10 , why is there no potential difference when wire is placed to connect both spheres??????

[brazenanomaly]

@santoyrayado Earlier in course it was proved that the electric field in a conductor is 0. deltaV = -Ed = 0 therefore the change the potential taken at any 2 points within conductor must be the same, ie equipotential. (by having conducting wire, two spheres become part of same conducting system.

[OKMUNWURX]

Each one of his lectures has something in it that his students will always remember. one time he shot a monkey with a golf ball. Here at the last 3 minutes, he sends some of students out with brown shorts.

[Luicho666]

6 people do not understand.

Excellent explanation, greetings from Argentina.

[07ziul]

The man !

[drewmagoo1]

Lol, he ended his lecture with a bang.

[drewmagoo1]

What the hell happened to his voice at 3:59?? It sounds dubbed.

[LegendLength]

@drewmagoo1

I totally noticed that too.

[universal23livenl]

Is this guy dutch? I think I'm hearing dutch in his accent.

[GunsNRosesbitches]

@universal23livenl yea he is

[ATIhYdrax]

@universal23livenl yeah he is, check out his wikipedia page, his name is Walter Lewin

[souroukou]

@MaximPodolsky you are right. Graduate school is a bit different. I didn't know that MIT pays graduate students. I will check their website again. I would really feel fortunate if I could be one of them. thank you again, Maxim

[zbret]

I have to say it - is that a banana in his pocket or is he happy to be there?

[souroukou]

@MaximPodolsky true but have you checked MIT scholarships?...I couldn't find any scholarship from/for this institute that covers even the tuition alone!

[MaximPodolsky]

@souroukou You don't need MIT to become a scientist... I am not aware of the scholarships offered by MIT, because i'm not an MIT graduate. However I do know that there ARE universities that will offer ppl with top grades enough money to cover the tuition. For a bachelor's degree it isn't exactly nessesary to go to MIT or another top university. Grad school is a bit different, and MIT does have some serious advantages there, depending on the field of course. But in grad school MIT pays you.

[rsplenum]

This man make learning more fun than doing anything else on internet.

[souroukou]

why does good education have to be so expensive? Wouldn't the world be a better place if we all increased our IQs? MIT...open your doors to determined people who don't have $27,000!

[MaximPodolsky]

@souroukou determined ppl can get good grades while studying in a free high school and get scholarships? No?

[mdinka]

intelligent people usually don't buy any junk that is offered to them by the industry. they ask to many questions. so a general understanding about how things work is bad for business -- thy shall consume not understand. so in order to keep the industry and economy happy you need many, many dumb people (consumers) who happily consume (spend their money for) as many junk as possible created by the few clever and rich ones educated in MIT. So MIT stands right at the midst of this logic.

[MaximPodolsky]

@mdinka Of course it's reasonable to assume that companies need uneducated people who can buy their junk. But then again, isn't it true that even given a chance and free education there are still going to be people who simply won't be willing to learn and become educated?And I don't think I would be too far off if I assumed that those people would form the majority.

[mdinka]

@MaximPodolsky sure but people might think elite unis actually exist in order to enlighten the masses. Anything but.. Primarily elitist faculties exist to connect two sorts of people: very bright ones and very rich ones. B/c MIT, Harvard,... simply reduces the risk for the rich ones to loose money by supporting other people that are capable of doing things smarter than anyone else. So the bright invent, the rich cash in.

[LegendLength]

@mdinka

You don't need junk products or idiot consumer for a good economy. Tell me, do you yourself buy products and services that you think are good?

[burakasno1]

i wanne bet he is dutch

[DraSifisGr]

Walter lewin IS dutch :)

[shoobeepdoobeepdooba]

Why is there a banana on his shirt

[bigshel99]

this class was freakin' awesome... wish my classes were like this.

That gun would be great to do in the middle of class... that'll wake folks up

[mailoisback]

nice gun )))

[dingo27mobile]

Please what is step leader? Lighting?

[Scelenaarwen]

@dingo27mobile first electron in a lightning, the 1 that sets off the chain

[snoopdogsballs]

It makes me feel like shit that I couldn't make it to MIT.

The free access at the comfort at my cmoputer doesn't change that.

I feel this should be earned.

I suck

[parrotdick]

Dr. Lewin is a boss.

[rahulilrplac]

These lectures are the best thing that ever happened to me. Walter Lewin, you are a Hero.

Thanks to the MIT to give us a glimpse of the human ingenuity and what we have achieved as a species.

[ab330]

he may have just gotten off the banana boat....

[hnguyen70]

yes, there are 2 bananas

[jrnesbit]

I was hoping someone had a logical explanation for the banana??!!! its driving me nuts

[rattyextreme]

Wtf banana?

[TSP105]

yeah man, i've got to the stage where i know which lecture i'm on by what type badge he's wearing....

[chuming123]

wasted 54 min of my life but it was loading fast

[FlavoredCoffeeGuy]

If I were observing a faster than light field, that actually beat light speed and time, which way would a bolt of lightning travel comparing the observer to the actual physical directioin of electrostatic field? Well, if part of it were faster than light, some part would come from the ground, and some other part would come from the cloud because, electrons never all travel at the same velocity or have the Kinetic velocity. As a result, the arc would appear to come from both directions.

[FlavoredCoffeeGuy]

If the electron has mass, how much lighter is the Electrostatic Potential's Field? I'm just saying that the smallest fraction of energy and mass is beating light speed. Just the field, and the field can govern time in space, then you see electrons moving within that field where time can be reversed. In space, you can only exist in the time space of that space. If time shifts within that space, you go in that direction in time.

[7olusegun]

Was that a banana electrostatically attached or clinging to his shirt pocket?

[Diemedes]

@7olusegun

He's got a little magnet inside his pocket. I think he mentioned it once.

[7olusegun]

@Diemedes Ok thanx for the information; but I wonder how a magnet could magnetize a piece of banana fruit (?).

[Diemedes]

@7olusegun

Well, as you may have noticed it's not a real banana. It's like one of those magnets you place on your refridgerator, only that in his case it's a real-sized plastic banana attached to it. He more of those magnets, including one with a fake fried egg on it, IIRC.

[7olusegun]

@Diemedes Ok! but I wonder what he was thinking that made him attach a plantain fruit to his shirt! It shows a glimpse of some of the eccentric weird traits of some geniuses.

[ih8makinusernames]

lol now people can go to MIT from their computers....The internet is awesome :)

[castillolarar]

sumamente interesante, maestro ,alumnos, aula, conducta, conocimiento,ambiente propicio para aprender y enseñar....dominio del tema, fluidez, buena dicciòn, es una clase....quisier ser como este maestro....¡ lo hare!

[LUSZBEL]

no mames

[Dutch3DMaster]

I'm not sure why, but what makes me think that the tutor is Dutch?

He has such a fat Dutch accent.

Can someone tell me if he is ?:P

[amrosik]

yes he is.

[goodluckpeace44]

Dutchy guestly man

[Diemedes]

@Dutch3DMaster

He is Dutch, if you Google his name you'll see that yourself.

[fourwindsoh]

Electrosatic mechanics. something i'll never think about after 5 minutes from now. =D

[EnergeeResearch]

very good bring more on Tesla.. Man born before his real time in our science of understanding of electrostatic mechanics.

brother

[minus00]

god bless mit.

[Anothercoilgun]

I am half way in the video and love it. I always new imperfections played a role in lowering potential brake down. But now I understand that role is larger than first known. Curvature is awesome. It dominates the universe.

[FALOUTBOY101]

i wish they taught us this in grade 9 this is really interesting stuff

[dfnvksdvnvsdkvn]

o.c.

[killabilla]

he´s the best

[sn1pe352]

you can't touch my unified field theory which Ive taken from the ancients :]

[Etimespace]

I can explain magnetism

onesimpleprinciple com

Later i am gona make a magnetism video

Now you can check it out

No gravity video

Idea from Kuopio video is video where i told how visible universe really MOVES

Peace and Love

[jocksBASS]

are you a robot

[Etimespace]

No i am not!

I am to one, who know how this universe really working!

[sn1pe352]

great demos
