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-> ⟨Soviet Onion⟩ ⟪Standecco⟫ you did guess correctly that it was […] ⮪ ohh, so that's what xi is. We never denoted that in Fermi-Dirac Statistics or Bose-Einstein. We kept it as E - E_f 🙂

<queqiao-> ⟨Builderbast 🇺🇦⟩ nahhh ξ is flow vorticity of course
bees has quit []
<queqiao-> ⟨Zeusbeer⟩ Mhmm yes snakes
<queqiao-> ⟨Zeusbeer⟩ My favorite type of greek letter
<queqiao-> ⟨Transparent_Elemental⟩ >right-handed
<queqiao-> thankfully I've been living in R^n for the past half a year, hopefully I wouldn't have to leave that space any time soon and try to figure out what's a right-handed set of vectors again
<queqiao-> algebraic vectors >> geometric vectors
<queqiao-> ⟨Zeusbeer⟩ Are there people that unironically use left handed coordinate systems? That would just mess up cross products
<queqiao-> ⟨egg⟩ yeah, that is relatively common in the computer graphics world; it all works unless you mix handednesses.
<queqiao-> ⟨egg⟩ Which, of course, KSP does.
<raptop> Would you use one if you declare electrons have positive charge?
<queqiao-> ⟨Paculino (ŝi/ri/she/they)⟩ What sort of bugs does mixed handedness cause?
<queqiao-> ⟨egg⟩ Sign errors on bivectors, as Zeusbeer alludes to. I don’t think there are actual bugs in KSP from that, but it makes it very dangerous to work KSP’s APIs because of the risk of mixing handednesses.
<queqiao-> ⟨Paculino (ŝi/ri/she/they)⟩ I thought maybe it could mess up torque
<queqiao-> ⟨lamont⟩ KSP of course has vectors in both handedness and lots of programming bugs can be due to mixing them up
<queqiao-> ⟨lamont⟩ physics in theory doesn't care if you do math in a left handed coordinate system
<queqiao-> ⟨lamont⟩ but there's little gotchas like the fact that keplerian elements are all still right handed in KSP
