<0> Manyfold: good one.
<1> yes, its a funny one
<1> lol
<0> http://in.tech.yahoo.com/060708/139/65pz8.html wheeew.
<1> :D yahoo
<1> oh, have to go
<2> Does anyone know of video lectures on general relativity?
<3> JohnFlux_: don't be a video junkie read a book
<3> i just watch porns
<3> http://www.amazon.com/gp/product/0716703440/102-2195199-1336935?v=glance&n=283155
<3> and i read good books
<4> i cant read
<3> me neither
<3> does anyone know what this windows gunuine advantage tool is?
<2> hahaha
<5> hehe, torque might be a vector in a curved dimension? :-D
<5> ...hmm... where do those darn black holes get all that energy??? ..
<5> .... Anyone annoyed yet?
<5> You are evil....
<4> no, im not evil, im bored
<4> theres a difference
<4> not much of one
<4> but it exists
<5> we know
<5> I was just drunk-reacting to the "rules" when I came in on the channel :)
<5> .... and You preceeded to kick without question.... =evil
<5> ssshhhit...
<5> ..never mind.... Carry on being bored....
<5> Seriously!!!! Wooot?
<5> Get unbored or off the chan... (see, I don't really care)
<4> ok, now youre starting to annoy me :)
<5> hehe, Yea... So what's up? .... Besides being bored?
<5> Is there ANYTHING I dare say without fear of being kicked to another plane of existence here????
<5> .... I actually had a electron/photon question in mind...
<4> ask it, i dont know anything about physics
<5> Me neither... I was just wondering how that electron to photon thing goes, where thing go, and why they don't go anywhere...
<5> ...photons come out, are electrons lost?
<6> photons are analagous to the sound a rubber band makes when you snap it.
<5> ...that analog hursts my head..
<5> ... where does the electron go?
<6> down
<5> lol
<5> conversion?
<5> .... but doeasn't an electron have a m***? .... (do I need new meds?)
<6> the electron had the potential energy of being seperated from the nucleus, as it pops down closer, it loses some potential, gains kinetic which is converted into an E/M event: a photon
<5> kinky...
<7> hello.. I'm a bit confused about capacitance. Now I read capacitance is measured in farads and is the amount of charge on the plates per volt. So does that mean that a lower capacitance requires less charge to produce the same voltage?
<5> "the electron had the potential energy of being separated".... Hmm... Ok .... I'm getting this strange feeling of understanding the torque/vector thing.... I need a drink....
<5> I guess you need a bunch of electrons on one side or the other to get a charge
<5> .... I'm so ****ing lost....
<5> No, no, no, liar, makes no sense
<8> helllooo
<8> anybody from Texas?
<5> Has anyone been able to "clock" the velocities of electrons around a nucl?
<8> what's the pecking order of physics departments in texas?
<5> Whats the relation between the m*** of an electron an a proton?
<5> "the electron had the potential energy of being seperated from the nucleus, as it pops down closer, it loses some potential, gains kinetic which is converted into an E/M event: a photon" .... sounds like a burning galaxytwisting into a ... <you know what>
<5> ok, YOOOHOOO, MR COP, YOU CAN THROW ME OUT NOW, BECAUSE I AM MORE BORED THAN YOU
<5> ...or something
<5> FUA
<3> what an idiot
<9> Heh.
<10> what you talking about Manyfold?
<3> -jc
<9> I ***ume he's talking about _jc
<3> _jc
<10> very true, but it's not hard to ignore him
<3> i wonder what you say about me when i leave the channel
<3> good night
<10> issues Baloogan_?
<11> morning !Jreggelt
<12> the latent heat necesary to melt ice is 80cal/g. If 10g of ice at -20C is dropped in 20g of water at 60C, what is the final condition?
<12> ammount of ice remaining? amount of water? temperatur of the water?
<12> anyone?
<12> wake up ppl! Its only 5:30am!
<12> is light tranversal or longitudinal wave?
<13> lol
<13> google it
<12> what about the ice water question?
<14> ice at 20 --> ice at 0 (water looses heat/temp)
<14> then ice at 0 to water at 0
<12> your right.
<12> the awnsers are 0g 30g 40C
<14> 40 ?
<12> -20+60
<14> water 50 <-> ice at 0
<12> huh?
<14> when water cools ice it will have to loose 10deg to get ice at 0 ***uming specific heat is 1cal/gmdegC
<14> i could be wrong on the value
<12> water cooling the ice???
<14> ice is at -20 right? and i thought ice has the same specific heat as water, so it has to come to 0 1st to cool
<14> sorry 0 1st to melt
<12> right
<14> so now we get ice at 0 by letting the water cool to 50 (20g of water) that gives 200cal to cool 10g of ice to zero
<14> now you need another 800cal to get ice to water
<12> the problem says that the latent heat to melt ice is 80cal/g
<14> yes so 800cal for 10 g of ice has to come from 20g of water at 50
<12> i see...
<14> well so how you got 40 ? :(
<12> guessing
<12> lol
<12> i thought it was just an equilibrium thing
<12> i dunno
<15> encoded, light is considered transversal iirc but Tesla might have believed it was longitudinal. what we know for certain about light is actually not a lot
<14> Dan, i sked this question here sometime back
<14> how is burning something in a closed chamber different from radiation?
<15> zaphyBeeble, not sure what you mean
<14> i havea totally isolated environment
<15> ys
<15> yes
<14> i burn something, /i heat/ i do monkey stuff so that it gives out something which causes temperature to go up in that enviroment
<14> how is this different from "burning"
<15> you mean how is a chemical reaction different from a fire? it's not really. fire is what we call a chain reaction that gives off light
<15> usually due to heat but you can have cold fires
<15> for instance a fuel cell is a chemical reaction version of a combustion car engine. same checmical reaction just more calmly controlled in the fuel cell
<14> yes ok but it would all add up anyways
<15> sure same result
<15> all things being equal there is energy conservation
<14> hmm ok let me rephrase it, when we have say a high freq surge of a beam/ boing kinds
<14> it would definately burn something, that is how microwave works too
<14> would you call that "packet" or wave?
<14> in other words do you call bursts packets or waves?
<14> so that line between "longitudnal" and transverse is very fine..right?
<15> I would say that's part of what's unknown about 'electromagnetic radiation'. I'm no expert but I'm not sure that pulses have been studied a lot or are well known
<14> but yo do agree they are "pulses" to start with :)
<15> a pulse is a pulse :)
<15> it's the deeper understanding that is missing
<14> its the tesla edison thing again...
<15> quantum mechanics talks about waves of chance but not sure about potential which I guess a pulse/wavefront is
<15> in a sense yes
<15> what is it really...
<15> Tesla might have known
<14> ok here is my question
<14> you say a pulse is a pulse is a pulse
<14> but it is essentially a wave modified with spurts?
<15> I'm sorry I don't know all the answers yet :)
<15> from what I know noone really knows what light is
<15> they have good observations in many cases and decent models but not everthing
<14> :) my question is why does it have to have a solution, why should there be a "this is"
<15> y
<15> well it has to be something doesn't it
<14> what is space
<14> or vaccum?
<14> if it is something why does it have a dielectric constant
<14> if it isnt sorry
<14> when you define something you define it by its behavior, not by "its quantum" just like "why is carbon black" is an insane question, there is nothing which suggests "black" or why do certain metals have isotopes, why do we just not call them something else
<16> hey all
<16> I have a question...
<16> a photon can decay into a positron / electron pair
<16> and a positron electron pair can annhilate one another
<16> to create a photon, correct?
