Do not anxiously hope for that which is not yet come; do not vainly regret what is already past.
不要切望那未到的事。不要徒劳地为已经过去的事后悔。
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。
Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.
我们对自然的观察必须勤奋，我们的反思必须深刻，我们的实验必须精确。我们很少看到这三种方法结合在一起;因此，有创造力的天才并不常见。
The main purpose of science is simplicity and as we understand more things, everything is becoming simpler.
科学的主要目的是简单，随着我们理解的东西越来越多，一切都变得越来越简单。
