数学不仅仅是关于数字、方程、计算或算法：它是关于理解的。
People are afraid to pursue their most important dreams, because they feel that they don't deserve them, or that they'll be unable to achieve them. We, their hearts, become fearful just thinking of loved ones who go away forever, or of moments that could have been good but weren't, or of treasures that might have been found but were forever hidden in the sands.
机器并未将人类与自然的重大问题隔绝，而是让人更深入地卷入其中。
Life is ours to be spent, not to be saved.
