<0> Manyfold, you can't convert irc nicks into phone numbers? I'm disappointed <:| <1> lol <2> we need more goodlooking girls in #physics <2> suggestions? <1> we dont really need them <2> mefistofeles: well you simply don't cut it <0> Manyfold, all girls are good looking you just have an ugly brain ;) <2> :) <2> so who is left? <3> wooo woooooo <4> oh ye <3> there is a latex plugin for gaim??? <3> sweet <5> only renders if the window has been open, and you don't switch workspaces. <5> otherwise it's pretty sweet <6> Hey guys , have you ever been on alex chiu's website?
<4> who is he <7> doesn't ring a bell <7> hmm speaking of which I wonder what kind of sound wave distribution a rung bell produces. 3d 'resonance' <8> howdy <9> voot!!....i totaly raped that final exam! <9> mwhahaha! <9> stuck it in! <9> bah...where is Manyfold?.....i swair he wanted me to fail :P <9> such a bitter guy... <2> hello <10> hey <2> JabberWalkie: are you there? <9> Manyfold: yea <2> how was your exam? <9> Manyfold: good....i whooped its *** <9> but i have another one tomorrow, on proof... <2> well you know there are just 2 interesting PDE's anyway <9> going to be much harder I think... <2> wave and diffussion <9> diffussion? like the linear heat equation? <2> well they'll ask you to proof that pi is irrational <9> Manyfold: errr.....dont know about that....... <2> like schrdinger eqn <2> wait tomrrow is saturday <9> Manyfold: for you <2> ? <9> its still thursday here... <2> whqat's your time? <9> 9pm abouts <2> well i have 6:10 and i just awackened <9> hmmm.....how to prove that pi is irrational... <2> anyway time to start the day <9> Manyfold: have fun.... <2> JabberWalkie: i'll tell you next time just ask me <9> k... <11> ***ume pi = a/b and show a contradiction <9> hondje: yea but i need to know some basic properties of pi.....and im not sure what i can use <9> like using a taylor expansion on arctan might be overkill.... <12> JabberWalkie: how about constructing an N-gon, as N->infty <9> Hydrargyrum: yea that could work.....but i doubt ill get a question like that.... <9> if anything it will be somthing like prove sqrt(5) is irrational <9> not pi :P <11> Hydrargyrum: Someone stole your nick? <12> hondje: I stole my nick <12> I logged in with a new one before old one pinged out <12> not a big deal, considering this is the correct spelling anyway <9> why cant people learn about the wonders of ghosting... <12> my brain is full <13> well, my pool ball simulation is coming along... so far ive got momentum being mostly conserved, but energy isnt behaving <14> im really liking this channel <15> jreggelt! morning <0> I only found one decent cartoon this morning. <16> what is the interpretation referenced in these two paragraphs? (quantum mechanics related) http://tinyurl.com/m9ph4 <2> hello <16> hello <17> Manyfold:hello <2> hi pgm <16> where can I read Feynman's PhD thesis ? <16> sum-rules describe quantum processes, right ?
<16> boing <18> hey Danf_DrC <0> feynman's thesis chttp://tinyurl.com/s84zj <16> table of contents :) <0> feynman's thesis http://tinyurl.com/s84zj <0> really :( <16> but it was a nice shot hehe (that's what I found upon googling) <0> I was going to suggest cal techs site <16> hm? <2> so what is renormalization all about and why can i use it? <2> is there any mathematical justification for it? <2> any takers? <16> sum-rules describe quantum processes, right ? <19> well some rules certainly do :P <16> heh <2> kanzure: you integrate over the weighted action <16> Manyfold, what? I think you dropped a few context-clues for me :( <16> *you forgot <2> lets suppose L is our langrangian <2> we know from cl***ical mechanics that delta L=0 <16> well, first I have to point out that I am but a newbie, and lack the calculus and physics to immediately understand you <16> you were telling me what to do (integrate over the weighted action), whereas I was asking something seemingly different <16> unless you can show how the two (my question, your answer) are related :) <16> Manyfold, ? <2> kanzure: it's hopeless to explain this to you without calculus <16> what about some basic calculus? <16> basically I have the jist of (anti)differentiation but no hard-experience <19> integration is basic calculus :| <2> but i thought you asked for the quantum path fomalism <16> hmm <16> maybe I did <2> oh i made a misstake <2> S is the action <2> S=int L dt <2> now delta S=0 <16> hm, how can I word my question? (proper background would help for starters like myself) <16> I look at the sum-of-paths idea as a method of predicting quantum states, (right so far?) <2> kanzure read QED by feynman <16> so in essence it is the start of a method of predicting processes, like (on a larger scale) perhaps the behavior of an atom <16> but is that right? Are path integrals the "path" to predicting atomic behavior (among other things)? <16> Manyfold, certainly :) <2> http://www.amazon.com/gp/product/0691024170/sr=8-1/qid=1154116851/ref=pd_bbs_1/102-6600398-5897706?ie=UTF8 <16> yeah I had it up ;) <2> well the path refers to something more abstract <16> right <2> the langragian describes the system in a space called configuration space <16> the idea of the paths, however, is that once you add them up, you get the quantum amplitude <2> which is Q x V x t <16> (what is? a continuation to your message, or mine ?) <2> where Q are the statial dimensions V are the velocities and t is time <2> we should ban everyone not an undergraduate physics student <2> spatial <16> is there an 'index'? the states of the particles are only applicable to those particles, so I doubt that the langragian is -- <16> oh :( spatial :( <2> yes thats the basic idea add up over every possible path <16> and this quantum or probability amplitude describes the particle's position, yes? (per Wikipedia) <2> darkgreen: whats prozack? <16> I think it's something for old people heh' <0> anit-depressent mispelled. <16> or at least the more elderly <16> ah nevermind <2> kanzure: lrts first get a grip of that langrangian thing <16> so I was originally thinking that the sum-over-possible-paths is like a precursor to building (modeling) of larger processes, hopefully one day on the scale of entire atoms, molecules, and larger <16> since the sum would describe the probability of a certain position <2> kanzure: stop babbling and listen <16> Manyfold, sorry :) <16> do go on <2> that's what i hate most about noobs <16> we listen? <0> no that you try to be creative
