Because it’s always evolving, and people always need clarification. AJATT.com — that’s this site — has grown quite a bit over the years, from its humble beginnings in 2006 to its arrogant, bombastic, decadent present.
So what? Easy now. So there you are. But now you’re here and you’re just confused. Short answer: Nutshell. Nutshell? In college, I read a slim volume by a man named Adam Robinson (the man who more or less invented the (SAT) test prep industry), called What Smart Students Know. Nutshell is basically that.

法国物理学家 Jules Antoine Lissajous 曾在 1857 年研究过这类曲线，因此人们把它叫做 Lissajous 曲线。 我在 reddit 上看到了一个 Lissajous 曲线的动画演示，觉得看起来确实非常爽；但那个动画里没有解释曲线的生成方法，很多细节也有让人不太满意的地方，于是决定自己制作一个。 这个动画展示的是 m = 13, n = 18 时的 Lissajous 曲线。 2016 年 7 月 30 日至 8 月 7 日，第 39 届欧洲杂耍大会（European Juggling Convention）在荷兰的阿尔梅勒举行， 8 月 3 日凌晨的搏击之夜（Fight Night）自然再度成为了众人关注的焦点——它是杂耍斗（combat juggling）这项运动最大的赛事。 在杂耍斗的圈子里，有两个响当当的大名你必须要知道：德国选手 Jochen Pfeiffer 目前世界排名第二，之前拿过 6 次搏击之夜的冠军；英国选手 Luke Burrage 目前世界排名第一，之前拿过 8 次搏击之夜的冠军。 杂耍斗是一种两人对战类的体育运动。 典型的一局比赛大致就像下面这样。 TED: Ideas worth spreading. 果壳任意门 - 发现你最爱的网站. 18個月週記系列. 自然笔记.
