The best time to plant a tree was 25 years ago. The second-best time is today.
种树的最佳时间是25年前,第二好的时间是今天。
科学不仅仅是关于事实,而是理解支配这些事实的基本原理。
我认为小说的意义就在于此,理解世界,理解生活。
引用计算机科学家Alan Kay的观点
Give the pupils something to do, not something to learn; and the doing is of such a nature as to demand thinking; learning naturally results.
