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。.
64 views, 对不起我为它花费的心血,还是面向大v发推吧,各位大佬随意看下,如果觉得写的不错顺便转赞评一下🙏 @laixintao @yihong0618 @disksing @frankluo2005.

By Long Luo 网络安全界的大牛 袁哥 在微博上发布了一道 数学挑战题 : 计算 \((3+ \sqrt{5})^n\) 的整数末三位数,给出能口算或者可以用计算器计算的算法的第一个人,免费给一个价值 1000 元的 A9 投资分享群入群名额。 我的解答 刷微博时看到这道题目时,我觉得很简单啊,于是马上给出了下面的解答: 令 \(y = (3 + \sqrt{5})^n\) ,两边同取对

Ben, I like your videos about math stories. 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:

斯特林公式(Stirling's Formula):我一个阶乘表达式,怎么就和圆扯上关系了呢?如何推导出斯特拉公式. @virushuo @yihong0618 @yuange75 @mtrainier2020 @amehochan @huihoo @davidfeng88 @dotey @chaos_scut @feltanimalworld @jesselaunz @juryxiong #math

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

Your math series always make me aha moment, Thank you, Danka.
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

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.
