<Ellied> jesus fuck, one of the admins at IIT responsible for sending out emails to everyone on academic probation (which includes me, since I took one class there and failed it) just did so, university-wide, without using BCC.
<Ellied> I could not possibly have decided to quit this place too soon.
<Ellied> perhaps this particularly admin will be following me out the door.
<UmbralRaptor> o_O
<UmbralRaptor> I, er, have to ask -- why the class at ITT?
<UmbralRaptor> (And what class?)
<Ellied> circuit analysis I. turns out, in my research prof's words, it's very hard to get me to do the same thing twice.
<UmbralRaptor> Ack. Tevenin and norton circuits everywhere.
<Ellied> predictably, it was Laplace transforms that killed me
<Ellied> after going over and over kirchoff's laws (that I already new backwards, forwards, intoxicated, and sleep-deprived) it was very hard to suddenly jump into something I actually had to apply differential equations to work out
<Ellied> this in a class of like 200 people, with no office hours to speak of? yeah, no.
<UmbralRaptor> eep
<Ellied> so yeah, I fucked that up, but I also learned that I don't really want to be a EE anyway. Physics is more my thing.
<UmbralRaptor> I think SnoopJeDi and I are obligated to celebrate that.
<UmbralRaptor> Still, on an academic probation list for a school you're not even attending is amusing. Email spam aside.

<egg|work|egg> bofh: if you have a Hamiltonian that's quest kinetic energy + some potential (q), can you get something with Noether from the invariance (which isn't quite an invariance, the Hamiltonian changes, but feels like one) under adding the same thing to all velocities?
<bofh> this sounds literally like just doing a Lorentz boost but I could be misunderstanding you. anyway I, erm, think that does follow if you write out the PDE for conserved currents under that Hamiltonian and bash some computations, I'll look at it more latsr.
<bofh> what is the actual problem you're trying to apply this result to anyhow?
<egg|work|egg> bofh: I'm not trying to solve a problem, I'm trying to figure out how Noether's theorem works :-p
<egg|work|egg> bofh: and I wasn't talking about a Lorentz boost, just about a rigid change in velocity in eggstremely boring classical mechanics
<bofh> well okay the usual formulation of Noether's Theorem applies to symmetries of the Lagrangian, but it's possible to transform between that and the Hamiltonian picture (just tedious). hmm.
<bofh> like for instance if you have a Langrangian that's invariant under spatial displacement you get conservation of linear momentum (and the same for conservation of angular momentum if the system Lagrangian is rotationally symmetric)
egg|phone|egg has joined #kspacademia
<egg|phone|egg> Bofh: yeah but I never touched a Lagrangian, and translation->total momentum is three lines to prove with the Hamiltonian anyway
<egg|phone|egg> Bofh: Also with the Hamiltonian time->energy conservation verges on tautology :-p
<bofh> like the Hamiltonian and Lagrangian pictures are easily transformed between and a lot of these simple examples border on tautology there too :P it's just Noether's Thm applies to any general symmetry.
<egg|phone|egg> Yes, but is boosting really a symmetry
<bofh> Well translation in space is one of the generators of the inhomogeneous Galilean group so...

<bofh> offhand it still feels non-conserving except for certain hamiltonians
<bofh> but let me think about that and crack open a classical mechanics text
<egg> bofh: yeah it definitely doesn't conserve the Hamiltonian (e.g. if it's kinetic + V(q), V doesn't change and kinetic energy increases), but can we still get something out of it :-p
<bofh> yeah that's what I'm not at all sure about. in general, I'm going with no, but under which cases can we is more complicated :P

<bofh> SnoopJeDi: heh, it's kind of mesmerizing
<SnoopJeDi> my research scientist is being a real asshole about the interpolation he used so I'm stuck reverse engineering is fortran today
<bofh> that's always a "fun" time
<bofh> like I've been putting off doing the same for the past week, should prolly get it done since supervisor needs fixes to it in by tomorrow.
<SnoopJeDi> it's just really frustrating that I burnt up 2 or 3 months because the data he said he was using are totally not the data he was using
<UmbralRaptor> SnoopJeDi: Code not available upon request, but upon swearing an oath of fealty?
<bofh> SnoopJeDi: jesus fuck
<SnoopJeDi> I mean I assume he started from those data at least
<bofh> SnoopJeDi: what an outright asshole
<UmbralRaptor> Also, stabbity.
<SnoopJeDi> but 1-5% variation from a naive trilinear fit seems abnormal to me
<SnoopJeDi> and yea electric fields can be misbehaved sometimes but this data is smooth as butter so a naive strategy should be just fine
<bofh> yeah I somehow doubt some of this
<SnoopJeDi> I'm not really giving him a fair treatment in how I'm telling it, but I'm frustrated with him
<bofh> Like if I lost two months of work b/c of piss-poor communication I'd be pissed off too.
<SnoopJeDi> anyway I think what he's actually using is a bicubic interpolation
<bofh> Heck, losing half a day of NHFML magnet time earned someone a very snarky tirade for about 30 mins
<SnoopJeDi> which sure whatever I guess that's not an abnormal choice if you can live on the plane but this data has to be extended to 3D pretty soon and that seems like asking for trouble if the naive off-the-shelf-scipy-tool interpolation will do
<bofh> and that wasn't even a total loss thankfully, he only mostly bungled up the experiment setup but not totally.
<SnoopJeDi> in the end my grudge shakes out as something like 0.5° of RF phase so it's probably not actually that big a deal but I'm pegging an 11/10 on the petty meter today
<bofh> SnoopJeDi: yeah bicubic isn't my choice if I need to immediately scale up a dimension, and tricubic is nasty.
<SnoopJeDi> yea it looks pretty hairy
<SnoopJeDi> part of it's a cultural problem. To me, this looks literally insane: `Vres=a0+rx*(a1+rx*(a2+rx*a3))`
<SnoopJeDi> as if Fortran didn't have an exponentiation operator for legibility's sake
<bofh> SnoopJeDi: so you do want to use Horner's Scheme for polynomial evaluation because: A) it is better behaved numerically, B) it requires fewer arithmetic steps than the naive approach.
<bofh> like consider Vres=a0+a1*rx+a2*rx**2+a3*rx**3. That's 0+1+2+3=6 multiplies, whereas your line is 0+1+1+1=3 multiplies. this gets progressively worse for higher orders too.
<egg> bofh: hm, is it better behaved? iirc Knuth asks the question but doesn't answer (it is faster of course)
<bofh> (and this is assuming that the compiler turns **2 into rx*rx and not into a function call to f__pow8i4 or w/e
<SnoopJeDi> Fair enough
<egg> Casteljau's method is nice too
<bofh> egg: hm, I swear I saw either Kahan or Gerhard&von zur Gathen explaining why it is in the common case at least, but can't find it offhand.
<SnoopJeDi> For where this code runs (this isn't in the bulk, it's run-once code) I'd rather it be a bit slower but more explicit
<bofh> and yes, Casteljau's method is indeed nice.
<SnoopJeDi> but then, if readability were a concern would it truly be in Fortran at all? ;P
<egg> SnoopJeDi: so like Horner's method is such a common pattern that I'd be surprised to see a polynomial written the obvious way
<SnoopJeDi> yea that's kind of what I mean as far as cultural difference
<bofh> SnoopJeDi: yeah, for run-once code I say go with whatever is clearer (tho for me Horner evaluation of a polynomial is immediately obvious, but that's as a result of working with polynomial approximations to special functions a lot)
<bofh> yeah, that makes sense.
<SnoopJeDi> it's also just those clumsy human emotion things getting in the way
<bofh> like for me seeing explicit polynomial evaluation the naive way would trip me up for a bit, but for someone with less experience with numerical analysis coding styles, it would likely be the opposite, or could at least (as demonstrated)
<SnoopJeDi> this guy is frankly brilliant and it's a real shame he's hitched his wagon to my advisor's dying star, but he's so sharp that he truly does operate in the man-as-an-island scientific pattern
<egg> bofh: tbh if I saw a polynomial written without at least Horner (or fancier) I'd want to scrutinize the surrounding code for numerical insanity :-p
<bofh> yeah, like in general comment the shit out of anything unclear is my policy
<SnoopJeDi> very rarely is anyone but him working with anything he's built
<bofh> egg: heh, same.
<egg> bofh: comments \o/
<egg> 50-line comment blocks about the history of mathematics \o/
<SnoopJeDi> bofh, my biggest gripe about his Fortran styling is actually just the pattern of cramming as much shit onto one line as possible :P
<bofh> speaking of which in this code I'm stuck reverse-engineering I am fairly certain that not only did he reimplement RK4 in the init stage instead of using quadpack *but fucked it up*.
<bofh> I'm not enthused for the fixed-point iterates part of the code.
<bofh> > 50-line comment blocks about the history of mathematics \o/
<bofh> people need to do this more often, it's so useful and fun
<egg> SnoopJeDi: gah, awful modern fortran with long lines and code that starts on the first column
<bofh> yep, I, how do you fuck up writing naive RK4.
<egg> FORTRAN IV FOR THE WIN
<bofh> okay I like Fortran 90 BUT CODE SHOULD NOT START IN THE FIRST LINE

<egg> C AND COMMENTS ARE DENOTED BY A C, NOT AN EXLAMATION MARK
<egg> C I MEAN WHAT IF YOU DO NOT HAVE AN EXCLAMATION MARK
<bofh> * APPARENTLY YOU DO WHAT LAPACK DOES AND INEXPLICABLY USE AN ASTERISK
<SnoopJeDi> I think the only instances of indentation in his code that I've seen are for demarcating loops
<bofh> SnoopJeDi: *sobs*
<SnoopJeDi> but I don't get a right to an opinion there because I don't write Fortran
<egg> C I DON'T WRITE FORTRAN EITHER, BUT MAKING FUN OF IT IS A RECURRING THEME HERE
<SnoopJeDi> I'm particularly flummoxed by the halfway habits of folks who clearly learned F77 but also kept learning
<bofh> Oh?
<SnoopJeDi> I mean I get that Fortan will never have the culture of very explicit variable names, but it continues to look like golf in all the code I've seen
<bofh> C I HAVE WRITTEN A FAIR AMOUNT OF FORTRAN (SADLY?) SO YEAH
<SnoopJeDi> (which was generally *in* F77 at one point so it's just technical debt I guess?)
<bofh> before F77 even
<bofh> my one gripe is people not using "implicit none"
<bofh> b/c that leads to so many bugs
<SnoopJeDi> when the variables correspond to formulae it's usually not a big deal anyway

<UmbralRaptor> I like how that line implies that you're an alien or a time traveler.
<bofh> or a (n amateur) historian...
<UmbralRaptor> Well, yes.
<UmbralRaptor> silly paper is silly
<bofh> ahh.

<UmbralRaptor> Why can't chicago be, say, 300 km farther south?
<bofh> heh.
<bofh> when are you in chicago out of curiosity?
<UmbralRaptor> Probably not any time soon =\
