<Ellied> Hello yes, I am ellie, my qualifications include burning myself with soldering irons and building electrically-convincing fake particle and photon detectors, please accept my application to your grad school
<bofh> I'unno, those seem like pretty strong qualifications IMO
<Ellied> I wonder how long it would take a group of beamline scientists to figure it out if I surreptitiously disconnected a signal cable from an APD and attached it to an avalanche transistor instead
<Ellied> "I don't get it. It still stops when we lower the bias voltage, so it's not miswired, and if it were a bad detector, we'd just get nothing. Why won't it respond to light?!"

<UmbralRaptor> Eek
<bofh> Ellied: OH GOD
<Ellied> I mean as APS pranks go, it would probably be way better to just stick a regular cheap photodiode in an APD mount and make them think they destroyed an expensive detector for a few minutes when the HVPS overcurrent trips
<Ellied> (it would only be a good prank at the APS, because they already destroy expensive detectors fairly frequently, and wouldn't feel too bad about it. Wouldn't do that at a university.)
<Ellied> although really I wouldn't do any pranks at the APS as a student. :n
<Ellied> but the avalanche transistor thing would be pretty good
<bofh> yeah, it's quite clever
<bofh> and diabolical
<bofh> (heh, wonder why the APS goes thru detectors so quickly. high beam power?)

<Ellied> you only have to get unlucky once to kill a detector. It's just since they use them so constantly.

<Qboid> 2d 0h 0m 0s left to event #1: Falcon 9 • SpaceX CRS 12 [at 2017-08-13 18:57:00]. Say '!kountdown 1' for details

<Qboid> egg: ID: 0 | Name: H-2A • Michibiki 3 | Time: 2017-08-12 04:40:00 | Unixtime: 1502512800 | Left: 0d 9h 36m 47s
<Qboid> egg: Description: A Japanese H-2A rocket, designated H-2A F35, will launch the Michibiki 3 navigation spacecraft, the third member of Japan’s Quasi-Zenith Satellite System.
<egg> UmbralRaptor: can you repeatedly ping me before the launch? or just talk about floating point :-p
<Thomas> egg: Qboid can do that for you (assuming you get pinged when you get a pm): !kountdown -subscribe
<egg> Thomas: Qboid will talk about floating point? :D
<Thomas> No
<Thomas> But it will remind you about the launch :D
<bofh> egg|work|egg: so I legitimately am not sure if it's useful for any case other than the one you just gave.
<bofh> but I think so.
<bofh> (like I just haven't had a moment to think about how Noether's Thm applies to Hamiltonian Mechanics, but I suspect you're on the right path)
<bofh> !wpn egg|work|egg
* Qboid gives egg|work|egg a spiral muffin
<egg> bofh: well I think it should apply just fine to Hamiltonian mechanics, it's just that boosting isn't a symmetry, it's something less nice (but still it feels like it is something, and maybe we could get something out of it?)
<egg> bofh: also wrong egg
<bofh> egg: noted
<bofh> egg: also hmm
<soundnfury> !wpn egg
* Qboid gives egg a principal voulge
<egg> bofh: also, for Noether's theorem for total momentum, let Σ3 be the matrix (id3, id3, id3, ...), then total momentum is Σ3 p = Σ3 (dH/dq)^T; translation invariance is dH(q+Σ3^T δq)/δq @(δq=0)=dH/dq Σ3^T=0, QED
<egg> s/total momentum is Σ3 p/the variation of total momentum is Σ3 p'/
<Qboid> egg meant to say: bofh: also, for Noether's theorem for total momentum, let Σ3 be the matrix (id3, id3, id3, ...), then the variation of total momentum is Σ3 p' = Σ3 (dH/dq)^T; translation invariance is dH(q+Σ3^T δq)/δq @(δq=0)=dH/dq Σ3^T=0, QED
