“这就是将学习效率最大化的方式——即当你如此沉醉于做某件事情的时候,甚至都没有意识到时间的流逝。”我亲爱的艾尔伯特,昨天收到你珍贵的来信,我非常高兴。我一直在担心你不会再给我写信。我在苏黎世的时候,你告诉过我,我来苏黎世,你感到难受。因此我想,如果我们在一个别的地方相聚,一个没人来打搅我们的地方,会更好。我会竭力争取每年我们有一个月相处的时间,这样,你就明白你有一个疼你爱你的爸爸。你也可以从我这里学到许多美好的知识,这些知识别人不会轻易地教给你。我通过大量坚持不懈的工作获得的成就,不仅留给了陌生人,也留给我 “This is how learning is maximized - that is, when you’re so indulged in doing something, you’re not even aware of the passage of time.” "My dear Albert, I received your precious yesterday I am very happy. I’ve been worried you will not write to me anymore. When I was in Zurich, you told me that I came to Zurich, you feel uncomfortable. So I think it would be better if we were together somewhere else and nobody would bother us. I will try my best to get the time we get along with each month of the year so that you understand that you have a dad who hurts you and loves you. You can also learn from me a lot of good knowledge that others can not easily teach you. My achievements through a great deal of hard work have not only been left to strangers but also to me
