The Church says that the Earth is flat, but I know that it is round. For I have seen the shadow of the Earth on the moon, and I have more faith in the shadow than in the Church.
Ferdinand Magellan
'The Church declares that the Earth is flat, yet I am sure it is spherical. For I have beheld the silhouette of the Earth on the moon, and I place more trust in what I see than in what they preach.'

The sea is dangerous and its storms terrible, but these obstacles have never been sufficient reason to remain ashore...unlike the mediocre, intrepid spirits seek victory over those things that seem impossible...it is with an iron will that they embark on the most daring of all endeavors...to meet the shadowy future without fear and conquer the unknown.
Ferdinand Magellan
