把这一句，留给此刻的你
The knowledge and understanding of the world which science gives us and the magnificent opportunity which it extends to us to control and use the world for the extension of our pleasure in it has never been greater than it now is.
科学给我们的知识和对世界的理解，以及科学给我们提供的控制和利用世界的大好机会，使我们在世界中获得更大的快乐，这是前所未有的。
