<egg|anbo|egg> raptop: I am surpised it took this long to add [Kep09]
<egg|anbo|egg> surprised, even
<egg|anbo|egg> publisher = {Jussu \& sumptibus Rudolphi~II romanorum imperatoris \&c},
<raptop> Did a spacecraft write this paper?
<raptop> ah, Kepler 1609
<egg|anbo|egg> raptop: also letter of Bessel to Olbers
<raptop> !
<raptop> No, firefox, I meant "hypersonic", not "supersonic"
<egg|anbo|egg> raptop: conteggst is https://github.com/eggrobin/Principia/blob/cbrt-documentation/documentation/cbrt.pdf, footnote at the bottom of p. 21
<raptop> hah
<raptop> naturally private correspondece is correctly cited

<egg|anbo|egg_> raptop: I like Kepler’s thing of randomly dumping in a greek word in the latin
<egg|anbo|egg_> he does that a lot
<egg|anbo|egg_> (/me glances at the 𒋛𒄥𒊏𒀀𒌅)
<raptop> heh

* raptop pets egg|anbo|egg_ with a cat arbitrarily selected from the set of real cats
<egg|anbo|egg_> > In chapter 9 and 22 (Kepler [1627] 1969, Vol. X, 66–69 and 144–146) he uses an iterative approach to find the angel λ between the sun (A) and the earth (E) as seen from a planet (P) (see fig. 5).
<egg|anbo|egg_> CC whitequark, or something
<raptop> uh
<raptop> wait, that can be solved with triangles, right?
<egg|anbo|egg_> yeah fig. 5 is a triangle
<raptop> Once again, everything in life is triangles

<SnoopJ> triangles are the strongest shape, mr freeman
<raptop> Presumably a basic T-34, and not a T-34-85?
<SnoopJ> good question
<raptop> ...oh, right. The T-34's crew cats are Russian blues

<egg|anbo|egg_> [Conteggst from another place: the idea of programming languages for cats; and the realization that existing ones are, fundamentally, FORmula TRANslation, and deeply tied to the expressions of arithmetic and algebra; whereas the same mathematics have formerly been described more geometrically]
<egg|anbo|egg_> Astronomia Nova, or to a lesser extent Principia, are full of that sort of way of expressing things that we nowadays would using formulæ
<egg|anbo|egg_> https://i.imgur.com/UyWSHeh.png describes Kepler’s equation, the circle area DAQ is β+e sin β
<egg|anbo|egg_> The sum is expressed by adjoining areas, and the product by constructing areas from lengths (with a circle doing the conversion circular sector = angle, whose sine is a length)
<egg|anbo|egg_> whitequark: interestingly this hints at some typing; e.g. addition is only permitted between areas or between lengths, not between a length and an area; this actually remains in late 17th works that use formulæ
<egg|anbo|egg_> there you have polynomials whose coefficients are written as powers, so that term has the same overall power
<egg|anbo|egg_> i.e. instead of writing ax^3+bx^2+cx+d you get a^1x^3+b^2x^2+c^3x+d^4
<egg|anbo|egg_> so that all terms are of dimension 4
<egg|anbo|egg_> And the circle allows for some reduction in dimension, since you can see angles as either the arc length or the sector area
