大陆漂移的第一个概念早在1910年就出现在我脑海中，当时我在看世界地图，受到大西洋两岸海岸线吻合的直接印象影响。

Old paint on canvas, as it ages, sometimes becomes transparent. When that happens it is possible, in some pictures, to see the original lines: a tree will show through a woman's dress, a child makes way for a dog, a large boat is no longer on an open sea. That is called pentimento because the painter 'repented,' changed his mind. Perhaps it would be as well to say that the old conception, replaced by a later choice, is a way of seeing and then seeing again.

成功不是要成为最好的，而是要变得比昨天更好。
