A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
If there ever was a misnomer, it is ‘exact science’. Science has always been full of mistakes; they require a genius to correct them. Of course, we do not see our own mistakes.
如果说有什么用词不当的话，那就是“精确科学”。科学总是充满错误;它们需要天才来纠正。当然，我们看不到自己的错误。
It is only when our life proceeds within bounds and in an accepted, disciplined way, that the mind can be free.
只有当我们的生活以一种可接受的、有纪律的方式在一定范围内进行时，我们的思想才能自由。
