Universal Grammar, 2

Posted on by

Predicate logics may be viewed syntactically as Chomsky grammars. As such, predicate logics (as well as modal logics and mixed modal predicate logics) may be viewed as context-sensitive, or more typically as context-free, grammars. As each one of the four Chomsky-type grammars have equivalent automata, these logics can be viewed as automata just as well.

Memory 4

這段改編自 2010 年 4 月 3 日的對話。

正常健康的腦袋，不會記下所有東西，而會把經驗過濾，把握重點記下，把其他遺忘。所以，記憶既不是事實的全部，亦未必是事實的真相。記憶時常會不完整，甚至不準確。

一個簡單的實驗，就可以證實，「記憶」和「事實」，並非百份百相乎。你可以試試再看，一部以前看過的電影。你會發現，電影中的很多細節，和你的記憶不一致，甚至相反。例如，你記得某輛車明明是在畫面的左邊，重看時，卻發現它竟然在右邊。
