Abstract
I trace the attempts to determine the Earth-Sun distance, which is based on measurements of the solar parallax, from the naked-eye observations of Aristarchus of Samos in antiquity to observations of the transits of Venus in the 18th century, noting the nature of the observational errors involved in them. I then turn to measurements of stellar positions with meridian or transit telescopes in the 17th to 19th centuries using the eye and ear method of observation. I show how an analysis of the observational discrepancies in this method led to the discovery of an observer’s “personal equation,” and ultimately to the birth of experimental psychology.
