The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.
The universe is not only stranger than we imagine, it is stranger than we can imagine.
"The world is a book, and those who do not travel read only one page."
The joy of science is in the journey, not just the destination.
