Geometric Model by A . Harry Wheeler, Oblique Spherical Triangle

National Museum of American History

Object Details

Wheeler, Albert Harry
Description
During World War II, A. Harry Wheeler made several models relating to spherical trigonometry. This one shows four quadrants of the celestial globe. One represents the equator. The other three pass are perpendicular to the equator through the pole. One passes through point T (Tokyo), another through point H (Honolulu), and the third through point S (San Francisco). A trihedral angle made from pieces of white plastic creates a spherical triangle joining these three points.
For the pattern for this model, see 1979.3002.084. The pattern is dated 1945.
