When we first broke into that forbidden box in the other dimension, we knew we had discovered something as surprising and powerful as the New World when Columbus came stumbling onto it.

There's something about taking a plow and breaking new ground. It gives you energy.

In all parts of the Old World, as well as of the New, it was evident that Columbus had kindled a fire in every mariner's heart. That fire was the harbinger of a new era, for it was not to be extinguished.

The frontiers we broke into in the '60s are still largely unexplored.

It's a brave new world.

We see it [the as-yet unseen, probable new planet, Neptune] as Columbus saw America from the coast of Spain. Its movements have been felt, trembling along the far-reaching line of our analysis with a certainty hardly inferior to that of ocular demonstration.
