In block spacetime, there is no motion, except for labeling convenience.

Perseverance is important because, in a startup, nothing goes according to plan. Founders live day to day with a sense of uncertainty, isolation, and sometimes lack of progress. Plus, startups, by their nature, are doing new things — and when you do new things, people often reject you.
– Founders at Work, Jessica Livingston

這段改編自 2010 年 3 月 20 日的對話。
我發覺我習慣了「transcend 掉」別人問我的問題。我往往不是直接回答,如何解決那個問題。我往往都是解釋,為何那個問題不重要,又或者,如何令到那個問題不再重要。
有時,「解決問題」的最好方法,未必是「直接解決」,而是把那個問題「transcend 掉」,令它不再重要。有時,只要宏觀一點看,原本的問題,會顯得無關痛癢。而真正的問題,就會立刻出現。解決真正的問題,往往會簡單和容易過,解決原本的問題。
例如,在太空中沒有引力。太空人不能用一般原子筆書寫。於是,美國人花了數以萬計的金錢,去研發一種,在太空中都可以使用的「太空原子筆」。但是,蘇聯人卻選用了鉛筆 -不費吹灰之力,就解決了真正的問題,避開了原本的問題。或者說,蘇聯人透過解決真正的問題,去避開了原本的問題。
真正的問題是「在太空中書寫」。原本的問題「在太空中用原子筆」,只是表面的問題,所以可以 transcend 掉。
(這個故事是虛構的,而且違反科學,但適合用作比喻。)

One of the most useful mental habits I know I learned from Michael Rabin: that the best way to solve a problem is often to redefine it.
The way to kill it is to redefine the problem as a superset of the current one.
