Jules Verne,
Around the Moon — Chapter X
(1873)
“ The oblique course of the projectile, from its very obliquity, gave Michel Ardan some hopes of striking the lunar disc at some point or other. He could not think that they would never reach it. No! he could not believe it; and this opinion he often repeated. But Barbicane, who was a better judge, always answered him with merciless logic."No, Michel, no! We can only reach the moon by a fall, and we are not falling. The centripetal force keeps us under the moon's influence, but the centrifugal force draws us irresistibly away from it." ”
