Energy, matter, and information equivalence, 2

Another link is demonstrated by the Maxwell’s demon thought experiment. In this experiment, a direct relationship between information and another physical property, entropy, is demonstrated. A consequence is that it is impossible to destroy information without increasing the entropy of a system; in practical terms this often means generating heat.

Another, more philosophical, outcome is that information could be thought of as interchangeable with energy.

Serotonin

Although phobias and depression might be attenuated by serotonin-altering drugs, this does not mean the individual’s situation has been improved, but only the individual’s perception of the environment. Sometimes, a lower serotonin level might be beneficial, for example in the ultimatum game, where players with normal serotonin levels are more prone to accept unfair offers than participants whose serotonin levels have been artificially lowered.

默契

這段改編自 2010 年 3 月 20 日的對話。

現時的「大眾教育」模式是,在同一時間,一位教師對著一大班學生講課。那樣的教育成效,通常也不大。試想想,即使只對著一個人說話,要保證聽方明白,沒有誤解,就已經相當困難。

「對話」其實是一個互相 Model(建構思想模型)的過程。你我對話時,我是根據你的說話,推斷你的 思考結構 和 心理狀態 大概怎樣,從而將你的「思想模型」,安裝在我腦海中的一個「虛擬機器」之中。簡單一點講,我的腦海之中,會有一個「虛擬的你」,反之亦然。那樣,我就可以估計,下一句說話,應該對你講什麼。

隨著你我對話句子數目的增加,我腦中「虛擬的你」,就會越來越接近真實的你。而我所選擇的說話,亦會越來越令你共鳴。換句話說,你最終也會明白,我究竟在講什麼。

當我心中「虛擬的你」,非常接近真實的你,而你心中「虛擬的我」,又十分接近我的真身時,你我就為之「有默契」。
