在数学中，你不理解事物。你只是习惯了它们。

Come,my friends,Tis not too late to seek a newer world,For my purpose holds to sail beyond the sunset，And though we are not now that strength which in old days moved earth and heaven,That which we are, we are;-- One equal temper of heroic hearts, Made weak by time and fate, but strong in will. To strive, to seek, to find, and not to yield。
