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.

Technological innovation in mining isn't about replacing people, but about making their jobs safer and more productive.

你不能希望在不改善个人的情况下建立一个更好的世界。为此，我们每个人都必须为自己的改进而努力，同时也要为全人类承担共同的责任，我们的特殊职责是帮助那些我们认为我们最有用的那些人。

"In every equation, there is a story waiting to be told."

I believe in the passion of creation and that dreams are more powerful than facts.

作家必须甘于惊讶。
