Images and animations

So, simplicity is key, and they purport to write such a system in a mere 20K LOC. To that end, they propose a sort of great unification theory of particles (homogeneous, extensible objects) and fields (the messages exchanged by myriad objects)—well, yes, it’s just a metaphor, but you can see it in action in the paper, applied to images and animations. The report also explains how the physical metaphor is completed with a proper simulation of the concept of time.

Six Principles for Making New Things


Here it is: I like to find (a) simple solutions (b) to overlooked problems (c) that actually need to be solved, and (d) deliver them as informally as possible, (e) starting with a very crude version 1, then (f) iterating rapidly.

If you work on overlooked problems, you’re more likely to discover new things, because you have less competition. If you deliver solutions informally, you (a) save all the effort you would have had to expend to make them look impressive, and (b) avoid the danger of fooling yourself as well as your audience. And if you release a crude version 1 then iterate, your solution can benefit from the imagination of nature, which, as Feynman pointed out, is more powerful than your own.

Timetable for high school study 10.2

這段改篇自 2010 年 2 月 7 日的對話。

3 hours 理科
1 hour 語文
1 hour
3 hours 文科

另外一點是,在我每天的溫習時間表中,也必須要有語文科目,即是 中文 或 英文。其他科目,你可以作短時期(例如三個月)的操練,令到成績有明顯的增長。但是,你要提升語文能力的話,一定要靠長年累月的反覆運用才行。所以,你應該堅持每天也有「溫習」語文的時間。而時間的長短,反而不是大問題。


一般人只會做 教科書練習 和 歷屆試題,然後再背一大堆文法規則等。那些都是必須要做的。但是,要大大提升語文修養的話,除了「必須品」以外,你還應該長年累月,「身處語文之中」。例如,我在中六(中學六年級)開始,要求自己每星期也看一本書。第一個星期看一本英文書,第二個星期看一本中文書,第三個星期看一本英文書,如此類推,不斷循環。而那些書一定要是「語文正確」和「內容深刻」的。
