There will be several partial lunar eclipses, but no totals :-/ Total lunar eclipses are the neat ones because the Moon turns yellow-y, then orange-y, then copper-y, then red! Note that this eclipse is going to be LONG – FIVE […] Continue reading Continue reading

Hypatia – Historical Astronomers in Context (repost)

<note to students: I went farther than you need to because no one can use Hypatia as their historical figure> Hypatia was the first woman KNOWN to contribute to mathematics and science.  Her father, Theon of Alexandria, was a well-known academic and taught his daughter to follow in his footsteps.  Remarkably, she was the head […] Continue reading Continue reading
