La terre et la lune: forme extérieure et structure interne

Embark on a concise yet vivid tour of how humanity first imagined our planet as a moving celestial body. From the early musings of Thales, who first suggested the Earth’s spherical shape, to the systematic observations of Greek navigators, the narrative traces the slow shift from mythic description to empirical inquiry. It highlights how ancient calendars, eclipse predictions, and the practical needs of seafarers sparked a deeper curiosity about the world beneath our feet.

The work then moves to the age of precise measurement, showing how scholars combined observations of the Moon, stars, and terrestrial landmarks to estimate Earth’s dimensions and probe its inner layers. By weaving together historical anecdotes with the evolution of scientific instruments, the book reveals the gradual unveiling of our planet’s external form and hidden structure, inviting listeners to appreciate the foundations of modern astronomy and geophysics.
