raptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Galois. We currently target 1.8.1, and 1.9.1. <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… | <egg> also 4e16 m * 2^-52 is uncomfortably large

Kitten Dispenser. — how much harder is it to do an interplanetary transfer from a 28 degree LEO than from a polar LEO?
<discord->
I identify as an H-IIA. — why would you do an interplanetary transfer from polar LEO...
<discord->
I identify as an H-IIA. — easiest way to do lunar/interplanetary transfers is launching from the equator
<discord->
I identify as an H-IIA. — so you can get any inclination you want
<discord->
I identify as an H-IIA. — korou is very good for that
<discord->
Kitten Dispenser. — i only launch from KSC most of the time, just for a challenge
<discord->
valthewyvern. — I almost always launch from Brownsville, and obey range limits because I'm a masochist.

I identify as an H-IIA. — F
<raptop>
Just wait 2 hours (unless you changed the difficulty settings)
<discord->
valthewyvern. — Well, I take some liberties on what "range limits" means when launching at 51.6 degrees, but for the most part I don't fly over land.

experimentalshells. — does it just transfer messages between discord and IRC?
<raptop>
beep boop

(yes, that's what the bot does)
<discord->
Sumguy. — people still use IRC?

lpg. — experimentalshells wins some sort of prize for being maybe the first person ever to understand the bot's nature without any help

With a name like that, they could be 🥚 in disguise

Baselet. — Sure, but I run IRC through an ssh shell from a server so it matters not what the user OS is.

lamont. — fun with non commutative algebra. while the vessel rotation transforms into ECI with `Quaternion.Inverse(Planetarium.fetch.rotation) * R` the inverse vessel rotation `RI = Quaternion.Inverse(R)` i think transforms into ECI with `RI * Planetarium.fetch.rotation` because `(AB)^-1 = B^-1 A^-1` so the inverse rotation must be dual to the rotation since it transforms differently? i think i need anoth
<raptop>
non-commutative algebra isn't fun, and leads to the deaths of felines approximately 50% of the time

<discord->

<discord->
egg. — ???
<discord->
egg. — You typically identify spaces with their duals in this context since you have a canonical inner product, I am not sure what you are trying to say
<discord->
egg. — maybe you mean that the dual of an orthogonal matrix (its transpose) is the same thing as its inverse
