Editing Hipparchus (section)

==Modern speculation==
Hipparchus was in the international news in 2005, when it was again proposed (as in 1898) that the data on the [[celestial globe]] of Hipparchus or in his star catalog may have been preserved in the only surviving large ancient celestial globe which depicts the constellations with moderate accuracy, the globe carried by the [[Farnese Atlas]].<ref>{{cite journal |last1=Schaefer |first1=Bradley Elliott |title=The epoch of the constellations on the Farnese Atlas and their origin in Hipparchus's lost catalogue |journal=Journal for the History of Astronomy |date=2005 |volume=36 |issue=2 |pages=167–196 |doi=10.1177/002182860503600202 |bibcode=2005JHA....36..167S|s2cid=15431718 |url=https://digitalcommons.lsu.edu/physics_astronomy_pubs/4735 }}</ref><ref>{{cite journal |last1=Duke |first1=Dennis W. |title=Analysis of the Farnese Globe |journal=Journal for the History of Astronomy |date=February 2006 |volume=37, Part 1 |issue=126 |pages=87–100 |doi=10.1177/002182860603700107 |bibcode=2006JHA....37...87D|s2cid=36841784 }}</ref> Evidence suggests that the Farnese globe may show constellations in the Aratean tradition and deviate from the constellations used by Hipparchus.{{sfn|Hoffmann|2017}}

A line in Plutarch's ''Table Talk'' states that Hipparchus counted 103,049 compound propositions that can be formed from ten simple propositions. 103,049 is the tenth [[Schröder–Hipparchus number]], which counts the number of ways of adding one or more pairs of parentheses around consecutive subsequences of two or more items in any sequence of ten symbols. This has led to speculation that Hipparchus knew about [[enumerative combinatorics]], a field of mathematics that developed independently in modern mathematics.{{r|stanley1997}}{{r|acerbi2003}}

Hipparchos was suggested in a 2013 paper to have accidentally observed the planet [[Uranus]] in 128 BC and catalogued it as a star, over a millennium and a half before its formal discovery in 1781.<ref>{{cite journal |title=Was Uranus Observed by Hipparchos? |author=René Bourtembourg |journal=Journal for the History of Astronomy |volume=44 |issue=4 |pages=377–387 |doi=10.1177/002182861304400401 |date=2013 |bibcode=2013JHA....44..377B|s2cid=122482074 }}</ref>
