记录生活,记录自己此刻思维。过了几年再看,会惊叹自己当时居然是那样想的,记录会让自己感觉有穿越时空审视自己。.

@frankluo2005 对头,外界认可是刚需,但写文章绝不是获得点赞的最快途径,所以其实应该还是有内因的。.

大概2015年的时候我把每日日记都发在个人网站上,半年才会有平均30个浏览量,其中还有一部分是自己的。长期写博客的人我认为主要动机并不是追求外界认可,但浏览量确实会给人正反馈。我的日记后来浏览量很稳定,被人发现了,有被偷窥感觉就全部隐藏了。.

西点军校游记,肝了两周,hugo统计四千六百多字,预计阅读21分钟?感觉好久没写这么长的文章了。背下来之后感觉我也可以去当导游了?

Tivadar, I'm sorry I didn't read it well. The intuition from the graph is also impressive, the weight sum connect with the Markov chain. Thank you, Tivadar.

Tivadar, if matrices are graphs, how to get intuition of matrix multiplication? graph multiplication means what? Thank you.

In the early 1600's, arguably the biggest obstacle to scientific progress was . arithmetic. Scientists spent months doing longhand computations to test their ideas. But then, a new invention changed everything: logarithms. My new video, out now:

The single most undervalued fact of linear algebra: matrices are graphs, and graphs are matrices. Encoding matrices as graphs is a cheat code, making complex behavior simple to study. Let me show you how!

If it is raining, the sidewalk is wet. If the sidewalk is wet, is it raining? Not necessarily. Yet, we are inclined to think so. This is a preposterously common logical fallacy called "affirming the consequent". However, it is not totally wrong. Why? Enter the Bayes theorem.

江西高考自主命题时,数学试卷难度惊人。作为一名数学爱好者,也经常做点高考数学难题来训练下自己的思维,这几天把2010年高考理科数学的压轴题做了下,这道题构思非常巧妙,作为竞赛很合适,但作为高考题非常不合适。我的解析: @yuange75 @huihoo @amehochan #Mathematics

出乱扔,不要觉得程序员或者互联网行业素质高一点就不随地吸烟,多次在路上看到戴眼镜看起来比较斯文的在路上吞云吐雾,抽完烟头就随手一扔。.

国内二手烟真是太猖獗了,对于不吸烟者简直是Hard模式,在大街上随时要避开随时飘来的烟味。以前在大厂上班,一栋楼都是同一个公司的,在洗手间、楼道里都没闻到过烟味。最近几年在小公司上班,洗手间里除了早上没有烟味,空调开最大风速也是烟味不断。到地铁站的路上几乎看不到不吸烟的人,烟头也是到.

晚上睡不着,在youtube上刷到一个场景英语频道 Ariannita la Gringa 。结合视频场景,长的美,语速慢,我基本上都能听清每个单词,以后学英语就看她的视频了。

今晚第一次打了最近几年在北美巨火的匹克球Pickleball,虽然有点羽毛球基础,但已经2年多没去过球馆打球了。今天玩这种强度比羽毛球低一个level的pickleball一个小时后,心跳还是加快了很多。门槛低上手容易确实是其优点,所以受众人群特别多。今晚开始要练体能了!#Pickleball.

因为这几天法网女单决赛,然后搜了一些名字,于是知道了曾经电视报纸上经常出现但不太了解的名字:桑普拉斯,阿加西,格拉芙,大威,小威,辛吉斯等。我对网球不了解,至今没有打过网球,但是今天知道了阿加西Agassi,豆瓣上他写的自传评分特别高,准备近期花时间看完。#Tennis.

同时省会和沿海学校高薪挖了很多老师,所以成绩现在又回到了市级顶尖中学水平了。.

2025的高考数学题确实简单,相比去年难度下降了非常多,对学霸们就不太友好,拉不开多少分。可能是因为今年高中双休,要减负,难度降低了吧!我高考时前后几年省内自主命题,数学特别难,而我高中母校高三时就喜欢出专题研究难题,所以那几年高考成绩斐然。最近几年因为不允许跨区掐尖,.

人很多时候对于自己的问题是不自知的,即使知道了要改也很难,要不然为什么说江山易改本性难移。只能慢慢改一点点,每改一点都是进步!.
