🚀 Wan Hu, a legendary Chinese official, once tried to launch himself into space with gunpowder rockets.
Real or myth, the story captures a deep truth: we’ve always dreamed of the stars.
Read how medieval China imagined space and Earth's atmosphere:
Hipparchos based his improved model for the Sun on observations of the equinoxes, which explained both changes in the speed of the Sun and differences in the lengths of the seasons. He is credited with the discovery of a phenomenon called precession of the equinoxes. According to Roman astronomer Claudius Ptolemaeus, Hipparchos measured the longitude of several bright stars and compared his measurements with data from his predecessors.
Aside from the myths, the ancient Greeks were interested in rational explanations for the celestial phenomena they observed. They were influenced by Egyptian & especially Babylonian astronomy: Babylonian astronomers could predict the planets' motions with extraordinary accuracy.
The 2nd century BCE astronomer Hipparchos wanted to achieve the same level of accuracy as the Babylonians.
We finally published a #PleiadesGazetteer place record for the Antikythera shipwreck:

"The so-called Antikythera #shipwreck dates to the second quarter of the first century BCE. Sponge divers discovered the shipwreck near Point Glyphadia on the Greek island of Antikythera in 1900. The wreck has produced numerous artifacts, including an object known commonly as the Antikythera mechanism."

How Eratosthenes measured the earth: part 4 of 4.
The angle of the sun is the last hurdle Eratosthenes had to overcome with his data collection methods.
Here we review the popularly believed story -- measuring shadows of sticks -- before looking at a more likely and methodologically simpler alternative.
Concludes with a bibliography.

How Eratosthenes measured the earth, part 3 of 4: distance.
