Superb

[taikukaikei]

brilliant lecture!

[OKMUNWURX]

In this section of You Tube when I press [like] it is for the professor's technique and the fact that MIT has him and that they put all this on You Tube. Best thing that You tube could be used for. Effectively these could be telecourses, not unlike correspondence school

[lolkiwi]

EM was def. a weed-out course at my college

[sirHOAX]

Rutherford > Einstein

So, does 10 amperes in equal 10 amperes out? Who cares if it is driven by 30MHz, the delay isn't humanly noticable, and after a few times around the voltage is multiplied by velocity. It could run off of a simple resonant circuit if designed based upon it's natural resonance as a structure like the Van De Graff and it's dynamic capacitance. The higher Q at resonance, the closer to over unity.

[FlavoredCoffeeGuy]

@FlavoredCoffeeGuy 10 ampers at 10 volts, 100 watts. 10 amperes at 1 million volts, 10 million watts. It just represents a delay of 80us to get there.

[sirHOAX]

@FlavoredCoffeeGuy over unity is more or less taking average atoms that are otherwise in static stable states and able to bring them to higher states never letting them go back to their stable state. Once you harbor that potential sky is the limit for over unity devices. Oxygen, Argon, Hydrogen and Nitrogen are the key is you ask me.

[FlavoredCoffeeGuy]

@sirHOAX The Cyclotron, alone could hold potential if a high Q parallel resonant circuit were used to drive it. In a real sense, it all depends upon Q, and if Q is 2000 at 300MHz, the electrons leave the cathode at the center in a pulse 10amps. As the electrons gain energy the voltage goes up, and that effects power in watts, as long as the electron density doesn't change from the cathode.

[FlavoredCoffeeGuy]

@FlavoredCoffeeGuy I figure the hard part of putting anything like this into production or research would be the IAEA, looking at you like you're about to refine something fissile.

[sirHOAX]

@FlavoredCoffeeGuy .. the demonstration at the end of the video shows potential for tuning a reasonable output for alpha particles. Be a good meter for anyone looking to get started in this field of these type of anomaly. Would like to "attempt" to build this device. Any clue if this is regular alcohol he is using? Or something de-natured.

Is true as to conductors, inductors alike regarding timing and discharges. Could be a tenth of a millisecond to long or short negating these beliefs. Timing!

[sirHOAX]

@FlavoredCoffeeGuy ..15KV is a threshold for a lot of different type of interaction of most atmospheric gases. Who knows maybe even liquid forms, or different. This is why we need home/backyard/garage labs! Real world change happens at this scale. True believer. The inventive need to use our environmental resources which are free, and scalable for laboratory(home) use. Even basic studies for overunity. Gravity is another static, yet valuable asset. Let alone noble gases in a static state.

[inkara777]

that's really very easy! I guess it's first course, for beginners/

old USSR professors're rather good......

[Blackberrypipe]

I thought that MIT is a place where it is very hard to get there.. such a simple thing he talking about.. o god..

[andhosa]

well i dont think you get a degree if you pass just 8.02.. besides, it is really hard to get there, after all it is one of the best, if not number one of tech institutes in the world.

[panchoavendano]

where the hell are the electrons and the alfa??? i cant se them

[LegendLength]

@panchoavendano

They look like fuzzy white lines that fall down in the liquid.

[hla27b]

nuclear physics in class!

now thats very amazing

thanks mr. Lewin

[elliuozaG]

"Here's an alpha particle! I don't know what it's doing there..."

[jaketubedeja]

lol this guy , think his name is Walter Newman.. hes amazing :P

[saco88]

his name is Walter Lewin

[tony8montana8]

lol

[BGasperov]

Is there any place where I could find some sample MIT physics exams? I'm eager to see them!

[Alderade19]

that's what you get in colleg? can you upload something more complex? coz i'm so fucking smart.

[landin048]

take an English course coz yew kant spel

[eboyang]

He probably already took one, its not hard to pass an English course in community college.

[chickenbreaker]

would be interessted to hear you speaking dutch ...

[killabilla]

he should put a magnet near the thorium

it would be cool to see the "bubbles" bend

[landin048]

I think there was a place on the web I came across that experiment. Try a general Science Experiments search.

[NinjaAnimeNancy155]

this man is cool

[wopskank]

i can't seem to be able to post links..

go to wikipedia /Lorentz_force about half way down ;)

[boxa888]

i think once u hit a billion hz there would be faster than light electrons.

[boxa888]

everyone forgets about NIKOLA TESLA.tesla would have made it go faster than the speed of light using high frequency.most of the cyclotron tech came from tesla over 100yrs ago,around1900.thats a fact.whats evenbetter is tesla described the high energy particles before nuclear science was created in the30s-50s.scientist and science professors always forget about tesla,itssad.still very coolvideo.i really wish i was there to marvel that.best explanation about the particles ive seentoo,THANK YOU MIT

[wopskank]

Scientist remember tesla infact there is the SI unit called the Tesla and most scientist know the AC/DC story (Tesla Vs Edison) if you sprinkle a little relativity on tesla work all works out ok , but he didn't believe in relativity thats why he got some faster than light answers...

physics works.

[boxa888]

ok if scientist know him then why wasnt he given the credit for finding high energy particles before the ballon experiments with cosmic rays,or xray , or even radio, were told marconi did it but its not true. ok please answer my question about frequency then. when a tesla coil is allowing electron discharge from the primary to secondary and back through the air which is say 1 food away. the electrons have to go back and forth say millions of times a second,

[boxa888]

then using d=r*t suggest that the electorns are going faster than light because they have to travel that distance. of course im not a genius at this but this simple aguement shows that the electrons are going faster than light. it seems correct but if u can help make my argument if ur argument that would be cool . thanks

[wopskank]

...i think this bloke talks about it in this lecture if not a few before... i hope i understood you question correctly...and that i don't sound like an ass. I love teslas work especially the reactive power oscillation stuff and his beatifull turbine...and of course his resonant coils : )

[wopskank]

arrr i sent you pm i can't post links n stuff...

[badeacartan]

@wopskank

May be he was right.... work on the Einstein Bose condensate has shown that the "absolute" nature of C, is actually quite relative :-0
