<0> i'm just glad that i have to live anywhere near you
<0> DevElara: thermodynamics
<0> once i see _any_ evidence that contradicts the laws of thermodynamics _ conversation of energy then we can have this disscussion again
<0> but until then you guys are acting like crazy fools
<1> The question is how can you use this to generate power? If you allow a metal object to be drawn towards a magnet you could get kenetic energy from that... so they use these low energy actuators to sheild the magnet and then the metal object gets pulled towards the next magnet... which then gets sheilded and so on... all the while you get Energy from the movement of the metal object... now... how much energy do you need to activate the shielding of the m
<0> DevElara: get a physics degree and then you would see how stupid that is
<0> i've had enough of you crazy people, i'm going to do some work
<2> hello
<2> any american here ? :)
<2> JohnFlux: or move here a little random violence is always apprenciate here
<3> heh
<2> JohnFlux: ever tried to use irc over the tor network?
<3> nope
<4> alright people
<4> i have a question about orbitals
<4> ill try and make it ***y
<4> when the orbitals are defined by the 1s, 2s, 2p, etc. why are they squared?
<5> squared?
<5> you mean the number of electrons? 3d9
<4> thinkchemical : well i dont know i guess.
<4> first of all, 3d is just a higher orbit, right?
<4> what i was seeing was 1s^2, 2s^2, 2p^2, etc...
<4> i ***ume that (for example) 2s in 2s^2 meant the secont orbit in the electron cloud containing 2 electrons with different spin
<4> is that wrong?
<4> i dont know why it would be raised to the 2nd power
<5> 1s^2 2s^2 3p^2 is a valid config, ^n representing n electrons
<5> i am UK and only a student so suspect....
<4> oh ok
<4> ha
<6> Yeah, that's not a power, I don't think
<6> It's just the notation
<4> hey so then uh..
<4> ok so maybe that makes sense
<4> 2 for second orbit
<4> ^2 for the number of electrons?
<6> # of electrons, yes
<5> good! im not going insane
<4> alright. ill ***ume that is the case, thanks guys
<4> so why different letters?
<4> beyond it just being a naming convention
<6> The spdf thing?
<5> different orbits
<4> why not have all orbits be S orbits
<4> just numbered in line
<4> same letter
<4> why not
<4> is there something unique about the s orbit?
<6> No, it's just the first one
<6> s-subshell is the closest one
<4> ok then explain 2s^2
<6> I'm trying to remember the quantum-number thing for these
<4> angstrom
<6> Mm?
<4> ?
<6> What about Angstrom?
<6> Okay, this seems pretty readable
<4> no nothing
<6> http://en.wikipedia.org/wiki/Quantum_number
<6> The electrons each have four quantum numbers
<6> And the fermi exclusion principle states that no two electrons in an atom can have the same set of quantum numbers
<6> So the principle number is just an integer
<6> 1,2,3,etc.
<6> These are the shells you're familiar with from high-school chemistry
<6> And then there are finer states electrons can be in - organised into subshells within these shells
<6> You know about the pattern in how many electrons can fit into a subshell, right?
<7> anyone know if those shell rules are derived or found by experiments? whether a base model predicts those shell configs
<6> They're derived from the values in that article.
<6> Some of 'em cropped up in solving the Schroedinger equation, some of 'em were experimentally found, I think
<6> Ah. The Dirac Equation
