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…

⟨Al2Me6⟩ Heh. I had a teacher who had a propensity to use "ξ" as an integration variable.
<queqiao->
⟨Paculino (ŝi/ri/she/they)⟩ I've had capital chi show up twice; it wasn't as difficult as the title text implies
<queqiao->
⟨Paculino (ŝi/ri/she/they)⟩ Oh, nevermind, I misread that somehow
<raptop>
λ: this math is rad
<raptop>
(ditto κ)
<raptop>
Λ: get the coefficients wrong, and all will be ripped apart
<queqiao->
⟨Al2Me6⟩ Found the cosmologist.
<raptop>
τ: it's time for an intervention
<raptop>
χ: either the poor sod using σ has gone even farther, or they got published
<queqiao->
⟨Quadrupole⟩ ι: when you want to cause confusion
<queqiao->
⟨Al2Me6⟩ Turkish i says hi.
<queqiao->
⟨Al2Me6⟩ * ı
<raptop>
ï
<queqiao->
⟨Al2Me6⟩ Surely you mean the second time derivative of ı
<raptop>
heh
<queqiao->
⟨lamont⟩ ⟪Al2Me6⟫ Heh. I had a teacher who had a […] ⮪ The apollo guidance papers use that symbol a lot
<raptop>
Anyway, symbols rated by increasing scariness: whatever latin < lower case greek < latin where upper/lower case matters < upper case greek < hebrew
<queqiao->
⟨Al2Me6⟩ There's a cardinality joke hidden somewhere in there.
<queqiao->
⟨Vlood⟩ s is definitely the scariest latin symbol
<raptop>
Also scary is when you start having to care about if the latin symbols ahve ^, ~, -, etc over them. Or non-derivative primes
<queqiao->
⟨Quadrupole⟩ One of the scary symbol I encountered was \vartheta. That's a sign that you have done so many substitutions and are running out of symbols.
<queqiao->
⟨Al2Me6⟩ I write my normal thetas that way.
<queqiao->
⟨DRVeyl⟩ ⟪Al2Me6⟫ I write my normal thetas that way. ⮪ Edgy!
<queqiao->
⟨Al2Me6⟩ _but it's just cursive_
<raptop>
Oh, yeah. When handwriting I sometimes do 2 different phis
<raptop>
albeit so far not in the same equation
<queqiao->
⟨Al2Me6⟩ Do one of the two said phis sometimes look like psi?
<queqiao->
⟨Al2Me6⟩ * Does
<raptop>
I guess one could compare them, though still different

⟨Transparent_Elemental⟩ not only was the topic of quasi-uniformly distributed integration points difficult to wrap my head around, but offensive xi usage made it worse

⟨egg⟩ Has someone mentioned ϖ yet?
<raptop>
That's up there with where you start using ☊ and ☋

⟨coffeequaffer⟩ was watching a leonard susskind lecture on quantum gravity & complexity. he ranted about obscure symbols for a bit then used A and B
