Hope for the best, but prepare for the worst.
抱最好的希望，做最坏的打算。
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。
Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.
不断地观察，所有的事物都是通过变化发生的，并使你习惯于考虑宇宙的本性最喜欢改变现有的事物，并创造与之相似的新事物。
When the scientific method came into being, it gave us a new window on the truth; namely, a method by laboratory-controlled experiments to winnow true hypotheses from false ones.
当科学方法出现的时候，它给我们提供了一个了解真相的新窗口;也就是说，一种通过实验室控制实验从错误的假设中筛选出正确假设的方法。
