If you think that you need a telescope to enjoy our gorgeous November night skies, think again! In 300 BCE Hipparchus invented the astrolabe. It was an all-purpose handy tool used to find the constellations in the night sky, as well as to measure rivers and buildings.  If you are interested in learning more about the astrolabe, please come visit me at www.MathScienceHistory.com. I'll have links to resources that can even assist you in building your own astrolabe!
