A little bit of yourself

Posted on by

In that instant, I realized how easy it is to give a little bit of yourself every day.

You may never know how much each gesture may mean to someone else.

Nerd 4

I thought it would be useful if I explained what a nerd was. What I came up with was: someone who doesn’t expend any effort on marketing himself.

A nerd, in other words, is someone who concentrates on substance. So what’s the connection between nerds and technology? Roughly that you can’t fool mother nature. In technical matters, you have to get the right answers.

時間定義 8.2

Posted on by

無錯。但是，我剛才所描述的，是「個體時間」或者「主觀時間」。而你所問的，是「整體時間」或者「客觀時間」。所以我說，你突然轉換了話題。

你所講的問題，其實就即是，當世界上有超過一個個體時，如何同步（synchronize）各個個體的「標籤系統」呢？或者說，「客觀時間」和各人的「主觀時間」，有什麼關係呢？

對於各個個體而然，「變化」的次序不可以亂。例如，你由 9 歲變成 10 歲，再由 10 歲變成 11 歲；而不會由 9 歲變成 11 歲，再由 11 歲變成 10 歲。這串次序，就是「因果鏈」，你的因果鏈。個體的因果鏈，就是「主觀時間」。

但是，「客觀時間」不只是由一條因果鏈，而是由無數個體的各自因果鏈所組成。要把眾多因果鏈合體，就要把它們「同步化」，從而形成一個「因果網絡」。這個「因果網絡」，就是宇宙的「客觀時間」。
