egg changed the topic of #principia to: Logs: https://esper.irclog.whitequark.org/principia | <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly…
<queqiao->
⟨Joshua Wood⟩ Really wish i could just input the burn time into principia 😢

⟨lamont⟩ egg what would you do in unicode if you wanted e.g. r_E for the radius of the earth? the subscripts and superscripts in unicode and the random support for different characters and the random placing of them in numerator/denominator locations by fonts is pissing me off and making me want to abandon trying to use unicode in code entirely... its like so close to being useful but so damn far...
<queqiao->
⟨sichelgaita⟩ It's a bit annoying, although in practice a good number of useful subscripts and superscripts are available. For the radius of the Earth, "R🜨" may or may not work depending on your programming language.

⟨lamont⟩ oh that's fairly cool
<queqiao->
⟨test_account9540⟩ how to even type those 🤔
<queqiao->
⟨egg⟩ Yeah, the letters are chaotic. The numbers are a complete set and are meant to be used for that, the letters are not encoded for that purpose (because matheamtical sub- and superscript use affects arbitrary expressions, so it quickly leaves the realm of plain text—we wouldn’t want to encode a superscript subscript!) but for orthographic or linguistic usage where they are one-offs (except i and n came in from other standards for...
<queqiao->
... cheap mathematical use).
<queqiao->
Of course, once they are there, Unicode is not the police, so you can use them (assuming a good enough font).
<queqiao->
⟨egg⟩ But because of that, my formal advice as liaison from Unicode to ISO/IEC JTC 1/SC 22/WG 21 for pretty-printing unit symbols was to use the subscript and superscript numbers and signs, but not the letters.
<queqiao->
On the other hand, sichelgaita and I use the letters a lot in our code.

⟨nazfib⟩ TWP2 gives you a 341 day transfer, that periapsis is in 90 days. You probably have the burn in the wrong location along your parking orbit.
<queqiao->
⟨Joshua Wood⟩ O i see, i thought TWP2 timer was for the burn, clearly not
<queqiao->
⟨Joshua Wood⟩ doesn't seem to want to optimise annoyingly
<queqiao->
⟨ezsnack⟩ does twp2 format the alarm description differently? how do you know its twp2... i mean i know you made it
<queqiao->
⟨nazfib⟩ The time (as it was in the original TWP) is _very_ approximate. It gives you the date of the launch, but not any more precision than that.
<queqiao->
⟨nazfib⟩ The clue was in the "Distance between bodies" line; that's not there in the original.
<queqiao->
⟨ezsnack⟩ didnt even realize its there good to know for antenna planning, is that the distance at arrival?
<queqiao->
⟨Joshua Wood⟩ it's much closer when i tunr up the tolerance, it's just 3fps lol
<queqiao->
⟨Joshua Wood⟩ it's very useful for antenna planing however i'm just going to wait a while in orbit till they are closer so i can transmit lol
