Title: Questions on this and other books
Review: Enjoyed the book very much, but still hung up on the distance equivalents of one degree of latitude at the equator and pole, page 30. At the pole, closer to the center of the earth, the distance should be shorter than at the equator, not longer. In fact, using the radii, I calculate 69.17 miles at the equator and 68.84 miles at the pole. Am I missing something?The books on Lewis and Clark always leave me with a celestial navigation question which someone may be able to answer for me. Meriwether Lewis was instructed in celestial navigation before heading west. He was to take data at key junctions to establish longitude and latitude. He did, but never reduced the observations to useable data. I never heard if the observations, reduced after the trip, were of any value. Any help?
