What experiments did Ptolemy do?

Answer 1

Ptolemy, the ancient Greek astronomer and mathematician, is best known for his work in developing the geocentric model of the universe, rather than conducting experiments in the modern sense. His major contributions came from meticulous observations and calculations of celestial bodies, which he documented in works like the "Almagest." He relied on observations of planetary movements and the stars to support his theories, but he did not perform experiments as we understand them today. Instead, his approach combined empirical observations with mathematical reasoning to explain celestial phenomena.
