Sane people use 2π = 𝜏 instead. permalink fedilink source hideshow 2 child comments replies: [–] JcbAzPx@lemmy.world 2 points 4 months ago* (last edited 4 months ago) (1 child) Actually a day is slightly longer than 2π since our orbit shifts the point of the circle that faces the sun each revolution. permalink fedilink source parent hideshow 2 child comments replies: [–] MatSeFi@lemmy.liebeleu.de 1 point 4 months ago Absolutely... Similar argument holds for the year btw. In that case it is better to treat a "day" or "year" as an artificial time constant and define them as 2π while skipping all the astronomical context. Otherwise you are free to write UT1D in a 2π notation also. permalink fedilink source parent
