New Method of Correcting Lunar Distances, and Improved Method of Finding the Error and Rate of a Chronometer by Equal Altitudes (Classic Reprint) - Tapa blanda
Sinopsis
This historical book improves the methods of measuring longitude. It draws from centuries of work that came before, including the difficulties faced by those who sail the world's oceans, the need for accurate timekeeping and the development of tools to help with that, the influences of astronomy and a deep understanding of mathematics, and the maturation of the sciences over time. The author shares numerous examples of observations, calculations, and corrections, all to aid in finding precise longitude through the use of lunar distances. This book is a valuable resource for mathematicians, astronomers, sailors, scientists, and historians with an interest in the deep and fascinating history of navigation and astronomy, and how these fields intersected and advanced through the centuries.

Excerpt from New Method of Correcting Lunar Distances, and Improved Method of Finding the Error and Rate of a Chronometer by Equal Altitudes
The error of the chronometer above alluded to is that which is obtained by apply ing the daily rate (multiplied by the proper number of days) to the error found before leaving port. The agreement or disagreement of the error thus found with that found by the lunar observation will be the test of the good or bad going of the chronometer.

Excerpt from New Method of Correcting Lunar Distances, and Improved Method of Finding the Error and Rate of a Chronometer by Equal Altitudes
To correct this Greenwich time, take the difference between the two Prop. Logs. In the Almanac which stand against the two distances between which the true dis tance falls. With this difference and the interval of time just found, enter Table X. Of this Appendix, and take out the seconds, which are to be added to the approx imete Greenwich time when the Prop. Logs. Are decreasing, b'ut subtracted when the Prop. Logs. Are increasing. The result is the true Greenwich time.
