Overview

La Caille was one of the observational astronomers and geodesists who followed Newton in developing ideas about celestial mechanics and the shape of the earth. He provided data to the great 18th-century mathematicians involved in understanding the complex gravitational effects that the heavenly bodies have on one another.

Observing from the Cape of Good Hope, he made the first ever telescopic sky survey and gave many of the southern constellations their present-day names. He measured the paths of the planets and determined their distances by trigonometry. In addition, he made a controversial measurement of the radius of the earth that seemed to prove it was pear-shaped.

On a practical level, La Caille developed the method of 'Lunars' for determining longitudes at sea. He mapped the Cape. As an influential teacher he propagated Newton's theory of universal gravitation at a time when it was only beginning to be accepted on the European continent.

This book gives the most comprehensive overview so far available of La Caille's life and work, showing how he interacted with his often difficult colleagues. It places special emphasis on his life at, and his observations and comments on, the Cape of Good Hope, where he spent the years 1751-53.

Editorial Reviews

From the Publisher
"A book previously missing on pioneering work in the field of geodetic astronomy has now been supplied by Ian Stewart Glass...extremely well researched, drawing on numerous manuscripts and printed sources that are listed in a remarkable bibliography. Students will find interesting discussions of Lacaille's training and his model of scientific practice. Experienced researchers will not fail to appreciate the scholarly care with which Glass has examined Lacaille's published and unpublished works." — Journal for the History of Astronomy
