<0> so the conversation seemed to go away from what i was asking so i didnt want to interrupt, now that there is a lull. if the concentric rings in this thing were made out of pyrex ( http://www.heatstick.com/ ) would it be as efficient?
<0> ive thought about it, and built one for my cold as hell room. at first i didnt understand why they used ceramic, as its a poor conductor of heat, dissipates heat well compared to other rocks, etc; but ive come to the conclusion that the point of this thing is to stop the air that is already hot from convecting, and make it conduct to the ambient air in the room
<0> so a metallic heat exchanger is not only unnecessary, but will steal some of my heat energy to make the metal do work in expansion and contraction
<0> so i guess the goal of this device (and my goal) is to trap candle flame's heat long enough to cool to a point where it will conduct more than convect heat, while absorbing as little as possible, right?
<1> Here's another suggestion
<1> When you get the urge to buy 100 tea lights.. pop aside or so
<1> Then after about 5 weeks, you can buy a radiator
<1> :-)
<2> woot, first draft of paper accepted, my 2nd ever :D
<0> James-S: i stated earlier i have access to a virtually unlimited supply of tea lights
<1> What about radiators
<0> paraffin is cleaner than the fuel burned at the plant per watt, and its free to me
<0> so rather than buy a heater ever, why dont i heat my room off of four candles for free
<0> and radiators = flower pots
<0> i got some of those
<0> got some bolts and washers too laying around
<0> James-S: but for normal people it makes sense to just by a radiator
<1> Heh, it's good to see ingenuity :-)
<0> i was just thinking i could buy some pyrex beakers, drill a hole in the bottom, and have it double as a lamp
<0> i use an ashtray and shot gl***es for the base :) but i dont know if pyrex would not work as well as terra cotta for some reason
<1> Why waste such pyrex
<1> :-(
<1> You can get pyrex pretty cheap off ebay, but then you can get a nice thick blanket for about also
<1> :-D
<1> :-P
<1> Well, smell
<1> Belonging to a man. O, be some other name!
<1> What's in a name? that which we call a rose
<1> By any other name would smell as sweet;
<1> So Romeo would, were he not Romeo call'd
<1> Retain that dear perfection which he owes without the title
<3> hi all
<3> I represent the Christian Anti-Messianic Church
<4> hi
<5> I wasn't aware they required representation in a physics channel
<4> did anybody see the new ms office?
<3> The One Eternal Truth requires representation anywhere it is not yet accepted
<1> Seriously, this isn't becoming any funnier
<6> Legal representation is in #legal.
<0> dmb_: just so long as "The Theory of Evolution" is included in you church.
<0> s/church/truth
<0> i actually gotta run tho, so pm me a response if you want and ill get back to u
<2> the interblags is full of trolls...
<3> FuriousGeorge how dare you speak about the falsehood of "evolution"! You must not speak of such unGodly falsehoods lest it inform others of its devious existence and lead them down the path of temptation

<2> thanks mbot :)
<2> for clearing that up.
<8> I have a physics 11 exam tommorow
<8> shouldn't be that hard...
<2> what sort of stuff we talking about?
<8> I need to study light and optics more
<8> basic kinematics, etc
<9> I need to find the intersection point between a static line (2D plane) and a point moving along a circle. How can I do this?
<5> #math
<9> Basically, I want to take rotation into account for my collision :)
<9> microacg: I'm there allready. I've allready asked, but didn't get an answer.
<9> Sorry if my issue is off-topic here though.
<10> hello
<10> any freebsd users here?
<2> does mac OS X count ? :p
<10> i was asking cause i want to run my teamspeak server in a jail
<5> uh jail?
<5> runs rather
<10> http://phk.freebsd.dk/pubs/sane2000-jail.pdf
<10> microacg: do you play counterstrike or world of woarcraft or something like that?
<11> hello...
<11> can anyone lend me a hand? cant get pspice to simulate my easy circuit
<2> i call....not going to lecture tomorrow
<2> :D
<10> what is pspice
<10> ?
<8> bah I'm confused, frequency and period
<8> I know they are inverse of each toher
<8> but I get confused as to which each one means
<10> have to go to sleep good night
<12> frequency is the number of periods ina second
<13> Peyton Manning, you have thrown a touchdown into my heart...
<8> but what is period/
<8> how long it takes for one cycle?
<8> so if I have the information
<8> 4.0e1 times in 5 minutes
<8> what is the period, 4.0e1/300s ?
<8> or 300s/4.0e1 teims
<8> times*
<8> nvm I got it
<14> yeah sure .. i guess thats why they say good news...
<15> hey anyone know how to compute <x|p> ?
<14> i installed the program Lightspeed from a Suse distro today . looks cool . but havent yet emulated the near speed of light..
<15> dn4: oh sure, greet #math but dont greet us....well fine then!
<16> :-/
<15> D:
<15> :D
<16> Greetings Physics Earthlings
<15> :)
<16> This is a great picture http://nbots.net/irc/tmp/2507_image.jpg
<17> JabberWalkie: turn your head and cough, please
<15> dems alot of hard drives
<16> How would you measure electromagnetic fields?
<18> Hm, what is there to measure, anyway?
<15> not sure exactly
<18> Seems like there would be way too much interference of nearby electromagnetic waves
<16> ok
<18> right?
<15> god no
<16> http://www.unitednuclear.com/magnetfull3.jpg <-- Neodymium Magnet
<16> how do you measure that magnetic field
<15> im sure there are ways......a loop of wire would do the trick.....
<15> although a bit crude
<15> probably a loop of wire that rotates at a known speed
<15> should get you an average magnitude
<15> or if you wanna go high tech you can use a squid
<15> just plop em right on there
<15> make sure he dosn't get away
<16> hmm okie dokie
<15> im not sure how to measure an electric field...
<16> Maxwell's equations might help
<15> guess you could measure the voltage across a conductor as it is emmersed in the field
<16> hmm good idea
<19> you can buy tiny cheap telsa meters.
<19> they are somewhat calibrated.
<15> ne1 know how to compute <p|x> ?
<20> has anyone heard the explanation that a lens does a FFt
<20> i find this interesting from a cognitive pov
<20> ok perhaps not a 'fast'FT, but a FT
<20> ok so apart from the lizard men and the men in black
<21> does anyone remember if there is a rule involving integrals of a complex exponential over a continuous variable and kronecker deltas?
<21> i.e. Integrate[E^(I*x(k-c)), {x, -infinity, infinity}] == KroneckerDelta[k, c]
<20> yeah there are definately rules for integration over kronecker deltaz
<20> iznt that the definition of a d{x}
<22> kronecker or dirac?
<23> quantum physics?
<22> ?
<24> hello
<25> yes and no
<22> Was that "yes and no" pointed at me?
<23> confusing here? like quantum behavior hehheehe
<22> Confusing?
<23> yes and no?
<22> This is definitely confusing.
