06:53 <egg|laptop|egg> CRS launch soon?

06:53 <egg|laptop|egg> mofh: meow

08:32 <egg|laptop|egg> mofh: hm, Principia doesn't have the precession of the equinoxes, but even then +365.317(69) seems long for a year,

08:37 <egg|laptop|egg> gah the true equinox-to-equinox time varies a lot

09:12 <egg|laptop|egg> oh maybe i should use the earthmoo system instead

09:12 <egg|laptop|egg> EARTHMOO

11:00 <egg|laptop|egg> hm, it's not about earthmoo, it just varies a ton...

11:03 <egg|laptop|egg> actually I can check that statement with the IMCCE calendar

11:03 <egg|laptop|egg> 2017: Équinoxe de printemps : le 20 mars à 11h 28m 39s

11:03 <egg|laptop|egg> 2018: Équinoxe de printemps le 20 mars à 22h 58m 27s TLF

11:04 <egg|laptop|egg> no that was 2019

11:04 <egg|laptop|egg> 2018: Équinoxe de printemps le 20 mars à 17h 15m 29s.

11:06 <egg|laptop|egg> so 2018-2017 is 365d 5h 17m 2s = 365,220162 d

11:07 <egg|laptop|egg> no that's 47 min, not 17

11:08 <egg|laptop|egg> 365d 5h 47m 2s = 365,240995 d

11:08 <egg|laptop|egg> gah i screwed up the seconds too

11:09 <egg|laptop|egg> why do i even try to do calculations by hand

11:10 <egg|laptop|egg> 2018-2017 is 365d 05h 46m 50s = 365,2409 d

11:11 <egg|laptop|egg> 2019-2018 is 365d 05h 42m 58s = 365,2382d

11:17 <egg|laptop|egg> the equinox for 2016 is at 04h 30m 12,40s UTC, so that puts 2017-2016 at 365,2489 d

11:31 <egg|laptop|egg> hm but i'm getting 365.113 for 2017-2016, even with the missing precession of the equinoxes that seems way off

16:27 <SnoopJeDi> Solid advice!

17:19 <egg|laptop|egg> mofh: I'm not sure what "calibrating the FMS angle at a particular epoch by its consistent evaluation for an average of the areocentric longitude at the successive Mars perihelia in 1996, 1998, and 2000." means in the description of Lee (1995) by Allison and McEwen

17:19 <egg|laptop|egg> and I can't get my hands on Lee

19:29 <xShadowx> could i pick one of your lovely brains for math? ;3 i know 'what' i want, but not sure the terms to look up for how to get it - i have 3 points in 3d space forming a triangle p1/p2/p3, and each point also has a normal n1/n2/n3, the direction it faces at that point, creating a curved/warped triangle shape. then i have a 4th point that would be on the same plane as the other 3

19:30 <xShadowx> somewhere in the middle of that triangle - how to calulate the position/normal that it would be along that curved surface?

20:16 <egg|laptop|egg> mofh: swat

20:17 <xShadowx> i think what i want is a bezier triangle?

20:19 <SnoopJeDi> your description of curves does sound like Bézier splining

23:02 <UmbralRaptor> Today in UmbralRaptor is silly, trying to figure out blackhole growth rates at the Eddington luminosity.

23:03 <UmbralRaptor> (exponential with a characteristic timescale of ~46 million years)

23:18 <egg|laptop|egg> It should be acknowledged that any adopted synchronization of ``Mean Solar Time'' is largely a matter of convenience. As noted by Woolard and Clemence (1966), ``a measure of Mean Solar Time which would depart too far from the average of the apparent solar measure would be inconvenient, and if too discordant would fail to serve practical purposes satisfactorily, but still would not be logically erroneous ...''. aaaaaa

23:19 <UmbralRaptor> Mean in at least two meanings of the word

23:47 <whitequark> rude solar time

23:54 <UmbralRaptor> But only an average amount of rudeness
