<0> whats_in_a_name: you can probably try.....im sure it will involve some bastardized approximation of quantum mechanics
<1> Hi!
<1> Can anyone answer the question I posted on this board? http://www.steorn.net/forum/comments.php?DiscussionID=43571
<2> phed: I... don't even understand your point.
<1> microacg: well, can magnetic attraction be quantified?
<2> magnetic attraction of what?
<2> can you be more specific?
<1> oh, so you mean it isn't quantifiable? Then the amounts of energy involved in a magnetic transaction are entirely arbitrary?
<1> err, I mean, they can possess any value?
<2> You are asking if magnetic force is limited to specific values?
<1> yes
<2> I don't see why it would be.
<1> hmmm, the magnetic attraction of the minimal system that can pose magnetic attraction?
<2> Now, I don't understand what you mean by that.
<1> well, if you were to construct a mini-magnet
<1> how much would attract once it starts attracting (so to say)
<2> phed, you can calculate the force very easily
<2> (relatively)
<1> mmm, but is there a lower limit for a magnetic system?
<2> That question doesn't make sense to me. What do you mean by a 'lower limit'?
<1> a planck-sized magnetic system
<2> such as?
<1> well, I am not entirely sure how small you can make a magnet really
<1> But if you had this really tiny magnet
<2> You can't really make it that small
<1> well, there has to be a limit
<2> magnets are formed by causing electron orbits to line up, I believe
<2> well, magnetic fields are created by moving charges so you can consider an electron a magnet, perhaps
<1> hmm, right. could a single electron have a magnetic field?
<2> if it's moving
<1> ok. but would the energy levels at that scale be quantified?
<2> hm
<2> the possible magnetic fields would be
<2> now the possible magnetic forces
<2> not*
<2> I guess the magnetic fields would depend on the velocity of the charge, and the kinetic energy of the electron is limited to specific values
<1> so .. magnetic fields are waves?
<1> right
<2> I didn't say that...
<1> right, laggy :)
<1> well, somehow I feel the magnetic domain should have quantum properties
<2> now that I think about it, it does
<2> but I don't think they are very important
<1> but the more I read about it (on the steorn forum of all places) it seems like they have quantum properties of higher affinity
<1> which seems natural, being they are secondary effects just as most other chemical effects
<1> (reading up on molecular biology you'll notice that proteins lives on a plethora of physical effects)
<2> I'll take your word for it
<1> mm it is quite interesting
<1> you know, proteins don't care. they just do what they do. just molecules acting with the forces of nature
<3> phed, what's the topic of discussion?
<3> electrons in proteins?
<3> http://www.physorg.com/news89562588.html
<4> ;-)
<1> actually, I started asking by if magnetism has quantum properties
<4> Righty, i'm off to bed
<1> but yeah, I read over some slides basically describing all known forces acting on a protein
<1> that was ... a bunch of slides
<4> Also, there's a huge lab closing down and they're selling off expensive equipment for nothing
<1> haha lucky
<1> I want a complete electronics lab : \
<4> :-P
<1> an acid-bath, ultroviolet shower and a supply of boards
<3> hmm
<3> I would like an electronics lab as well
<3> there was an article on Slashdot a while back
<3> that asked for the equipment for the ultimate lab
<3> so people replied with instruments for medical labs, chemistry labs, etc. etc.
<3> was pretty nice reading :)
<2> there's probably no such thing as an 'ultimate' lab
<2> too many things would be required
<3> yeah of course, I know microacg
<1> mmm
<3> microacg: But having the tools required for certain projects is still .. useful.
<1> well I only need a speaker and a waveform generator to entertain myself for a few hours
<2> phed: more like a few 'minutes' lol
<4> I managed to get some optical equip quite cheap; fresnel lenses, apertures and other things
<4> Some labs sell off their old stuff when they upgrade it all in the new year..
<1> microag: haha well, I'll start digging out materials to send it through :3
<1> hmm, this wacko still puzzles me at the steorn boards (too bad I don't have the link anymore)
<1> but he had made a lens which responded to magnetic fields
<4> Well, if anyone wants pipettes ;-)
<1> and pretty much made scalar 3d displays of the magnet when you moved it close by
<1> haha
<4> :-P
<3> "That means the electrons may sometimes leak from one chemical bond to a neighboring bond, he said. They also can take forbidden walks on the wild side by tunneling through open space."
<3> Electrons leaking from one bond into another?
<1> oh, statistics
<4> Quantum tunneling?
<1> yeah
<3> James-S: Is that it?
<4> Yea
<3> So, what's the story behind that phenomena?
<1> since it is possible to exists on the fringe of the bond, it might as well escape it
<3> *phenomenon
<4> http://www.barloworld-scientific.com/internet/BibbySite.nsf/framesetter/TMAY5BQDST?OpenDocument <-- enter a comp to win 0 of lab equip! ;-)
<4> All 0 :-P
<5> why is it that at higher orbits, the translational velocity is lower than a one at lower orbit?
<2> Do you want to know mathematically, or just want to interpret it?
<5> interpret
<5> b/c im confused since
<2> I think that's a bit tricky to explain :-(
<5> if you lower the velocity, dont you fall back to earth?
<2> but the further you are, the lower the escape velocity
<5> hmm ok
<5> so how would you change to a higher orbit, accelerate?
<2> Aerospace Engineer anyone?
<2> You'd have to do a burn...
<2> I couldn't give you the details though
<6> does anyone know more about the breakthrough with Maxwell's demon that's been circulating in the news?
<7> if F(static) = F(static max), does an object move or remain in equilibrium?
<7> ignore all other forces
<5> i have a question about orbital mechanics, im in a circular orbit, i use my thrusters and put myself into a trajectory, will i now be in an elliptical orbit around the earth?
<2> I think it depends
<5> hmm
<1> Axsuul: if you try to pull away from earth, you may both hit the ground or go into (a rapidly growing) elliptic orbit
<8> in a coupled oscillator laid out as followed: o--o--o with -- represneting springs with constant k... can that middle m*** be treated as being statinoary?
<9> hey guys. i have to write a paper for my particle physics cl***
<9> i'm looking for a topic
<9> any ideas?
<0> T2K
<10> particle physics!
<10> negative energy is an interesting topic.
<0> ;S
<9> it's gotta be something specific
<9> like neutrinoless double beta decay
<10> Oh, well there you go.
<0> T2K!
<9> synx: can't someone else is doing that
<10> ...oh.
<0> SR!
<0> SR is actually pritty cool...
<9> okay, so i'm writing my paper on neutrino m***
<9> basically theories which can give rise to neutrino m***es
<11> guys is there a chemistry channel?
<9> so far i've got majorana m***es and the see-saw mechanism (yes, i've only been looking at wikipedia)
<9> what other theories are there to give rise to neutrino m***es?
<12> prada?
<13> anyone on line this lovely evening
<7> me
<7> but i dont know physics
<12> nor do I
<13> then why here
<13> JabberWalkie?
<13> are you there
<0> yes
<13> Awww! have you missed me?
<7> im here because i want to KNOW physics
<7> :D
