模型是对现实的简化表示，但其价值在于它能够提供不立即显而易见的见解。

The beauty of a woman is not in a facial mode but the true beauty in a woman is reflected in her soul. It is the caring that she lovingly gives the passion that she shows. The beauty of a woman grows with the passing years.

科学不仅仅是寻找答案，更是提出更好的问题。

你的态度决定你的高度。

Watch your thoughts, for they become words. Watch your words, for they become actions. Watch your actions, for they become habits. Watch your habits, for they become your character. And watch your character, for it becomes your destiny. What we think, we become.
