whether it is an electron or a proton or an alpha particle — alpha particle is the nucleus of helium, it’s two protons, two neutrons. If it goes through the air it makes ions and as it goes through the air and it makes ions it slowly loses its kinetic energy and it finally comes to a halt. If we take a 10 MeV electron 1 atmosphere air it could go 40 meters. If you take a proton of 10 MeV it would only go 1 meter because the density of ions is higher because it has a higher mass and if you …

nuclear physics in class!
now thats very amazing
thanks mr. Lewin
would be interessted to hear you speaking dutch …
his name is Walter Lewin
lol this guy , think his name is Walter Newman.. hes amazing
“Here’s an alpha particle! I don’t know what it’s doing there…”
lol
He probably already took one, its not hard to pass an English course in community college.
Is there any place where I could find some sample MIT physics exams? I’m eager to see them!
I think there was a place on the web I came across that experiment. Try a general Science Experiments search.
take an English course coz yew kant spel
that’s what you get in colleg? can you upload something more complex? coz i’m so fucking smart.
he should put a magnet near the thorium
it would be cool to see the “bubbles” bend
this man is cool
arrr i sent you pm i can’t post links n stuff…
i can’t seem to be able to post links..
go to wikipedia /Lorentz_force about half way down
…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 : )
i think once u hit a billion hz there would be faster than light electrons.
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
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,
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.
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
