i nerd sniped myself tonight and i imagine the NSA operative who is assigned to me is very confused by the increasingly erratic and frustrated google searches for HOW DO I CALCULATE THE MOON WHERE IS THE MOON
-
i feel like i'm so close to getting this working. i found a simple implementation of ELP2000-85 that gives the approximate ecliptic coordinates and distance of the moon for a given julian century, i found math for translating between ecliptic and equatorial coordinates, and the math for working with the julian calendar looks easy enough, so i just need to figure out the missing conversions and decide on an internal time keeping standard
i think astronomy would be a lot simpler if ancient peoples didn't get so hung up on conceptualizing celestial bodies as spheres and simply invented linear algebra first

@aeva On cosmology sequence breaks: Terence Tao noted that an ancient Greek heliocentrist got his arguments shot down because others said, hey, if the earth moves so much yet the stars seem to stay still, the universe would have to be *thousands* of times bigger than anyone figures it is. And how would you know, back then, it was way *more* than thousands of times bigger?

@aeva a lot of things would be simpler if cults based on "perfect" shapes hadn't done all the [gestures] that they did
divine geometry is a helluva drug

@rf they were so close lol

@aeva on the other hand getting extremely horny for triangles is both funny and kinda relatable, so

@SnoopJ we're still using spherical trig in astronomy today despite earth being an ellipsoid

@aeva well, yea, because astronomy doesn't really give a shit what shape the earth is anyway

I just want to calculate the current direction of tidal force from the observer's earth-relative position in space and time is that so wrong
@aeva oh what a fun one
have you encountered the thing where every computation in astronomy is coordinate conversion

@ireneista yes

@ireneista yes
@aeva "fun", isn't it

i just want to calculate my current ecliptic coordinates from my current geographic coordinates is that so wrong

i wonder to what extent astronomy is an insomnia friendly career still, or if it's mostly just diurnals looking at spreadsheets in fluorescent offices these days

now that I'm a bit further down this rabbit hole I'm realizing this isn't much different from the terrestrial cartography I did one summer in college about 16 years ago, except that your benchmarks are all moving a lot faster

one of the benchmarks we wanted to use had a typos where two digits were transposed preventing us from using it because otherwise none of our math would have added up. the professor rejected my proposal to simply interpolate the error across all our data points to make the more convenient benchmark work out lol. so instead we had to chain our data points to a much less convenient datum which iirc involved us trespassing into a reservoir.

@aeva at least all the measurement units are nailed down.

Well, ok it could be worse.

@aeva I mean borders and locations of civil territories are actually definitively imaginary so that tracks.

Quizzino della domenica: tutti primi
@matematica - Se a+b+c=d con a,b,c,d primi, qual è il valore minimo di d?

time is fake, but as it happens space is also fake

anyways, somewhere in peru there's a town that is legally somewhere between 100 meters and 1 km off from where it actually is, and it'll be really funny if it ever gets big enough for that to actually matter

@ok That's what I thought.
