In this episode of The Mathematicians Podcast, Benjamin Cornish explores the life and work of Menelaus of Alexandria; the mathematician who transformed how we think about geometry on curved surfaces. From his treatise Sphaerica to the elegant power of Menelaus’s Theorem, discover how this quiet figure of ancient Alexandria helped shape spherical geometry, astronomy, and the trigonometry still used in navigation, GPS, and astronomy today.   The music was: "Danse Macabre - Finale"Kevin MacLeod (incompetech.com)Licensed under Creative Commons: By Attribution 3.0http://creativecommons.org/licenses/by/3.0/ Keywords :Menelaus of Alexandria, spherical geometry, Menelaus’s Theorem, history of mathematics, spherical trigonometry, ancient astronomy, Greek mathematicians, geometry podcast, mathematics history, Euclid, Hipparchus, Ptolemy, trigonometry in navigation, GPS and geometry.
