2023.03.31 三月读书总结

本月带娃消耗了比较多的精力,读书时间有点短。
这个月读完的 4 本书《观念的水位》,《唐诗寒武纪》,《天生有罪》,《成为乔布斯》,均强烈推荐。刘瑜的理性通透,各位初唐诗歌大佬的起伏人生,崔娃的奇特成长经历,乔布斯的辉煌与失败,都在告诉我们一个道理,有意义的人生就是要活出自己,别只是一个循规蹈矩为别人而活的打工人。

2023.03.30 为什么要学习微积分

这个答案也可以用于回答“为什么要读所谓的闲书”,“为什么要花钱旅行”等等问题。
I took calculus my senior year of high school, and I really liked the way our teacher framed this on the first day of class. He asked somebody to raise their hand and ask him when we would use calculus in our everyday life. So one student rose their hand and asked, “When are we going to use this in our everyday life?” “NEVER!!” the teacher exclaimed. “You will never use calculus in your normal, everyday life. In fact, very few of you will use it in your professional careers either.” Then he paused. “So would you like to know why should care?” Several us nodded. He picked out one of the varsity football players in the class. “You practice football a lot during the week, right Tim?” asked the teacher. “Yeah,” replied Tim. “Almost every day.” “Do you and your teammates ever lift weights during practice?” “Yeah. Tuesdays and Thursdays we spend a lot of practice in the weight room.” “But why?” asked the teacher. “Is there ever going to be a play your coach tells you use during a game that requires you to bench press the other team?” “No, of course not.” “Then why lift weights?” “Because it makes us stronger,” said Tim. “Bingo!!” said the teacher. “It’s the same thing with calculus. You’re not here because you’re going to use calculus in your everyday life. You’re here because calculus is weightlifting for your brain.” And I’ve never forgotten that.

2023.02.28 二月读书总结

本月被各种事情打断,加上懒惰症发作,读书时间太短。
这个月读完的 4 本书《现实不似你所见·量子引力之旅》,《神的九十亿个名字》,《送你一颗子弹》《植物的战斗》,均强烈推荐。

2023.02.27 读《现实不似你所见·量子引力之旅》

这本书是现象级科普畅销书《七堂极简物理课》的作者、意大利理论物理学家卡洛·罗韦利的新作,从德谟克利特到爱因斯坦,从法拉第到引力波,从经典物理到量子引力……通过对物理学认识世界的过程做一次考古,介绍了今天的物理学家是如何理解宇宙的结构的。
但还是没有看太懂,没看懂的原因是,里面的大部分概念已经超出我能理解的范围太远了,需要一定的现代物理学素养加丰富的想象力,两者我都欠缺。作为一个数学系的逃兵,我曾经在现代数学的大门口外,隔着门槛偶然瞟见过现代数学的一个模糊身影,但这已经足够让我震惊。经过几代地球上最聪明大脑的建设,现代数学早已不是算个几元几次方程、算个微积分那么简单的事情了,虽然这些对于普通人来说已经足够数学了,但依然早已经不算现代最前沿的数学了。现代最前沿的数学,那个我瞟见的身影,已经是把全世界所有事情进行抽象描述的最高哲学存在了。虽然从数学逃了,也看不懂最新的理论物理学科普了,但是学过和看过,这些经历还是对我有用,那就是让我更敬畏知识,敬畏这个看着普通但深邃无比的世界。《圣经》上说“敬畏耶和华是智慧的开端”,那让我先开个端吧。
