The Standard Model

The only special thing about the Standard Model is that it’s the “minimal” theory (when it comes to counting of the fields etc.) that is compatible with data we had known before the LHC.

Teacher’s wisdom

Passive acceptance of the teacher’s wisdom is easy to most boys and girls. It involves no effort of independent thought, and seems rational because the teacher knows more than his pupils; it is moreover the way to win the favor of the teacher unless he is a very exceptional man. Yet the habit of passive acceptance is a disastrous one in later life. It causes man to seek and to accept a leader, and to accept as a leader whoever is established in that position.

Firmware 3

這段改編自 2010 年 3 月 20 日的對話。

「韌體」本身是「軟件」,因為它是由一堆程式指令所組成。但是,你亦可以把「韌體」看成,介乎「硬件」和「軟件」之間一個概念,原因是:

第一,「韌體」是直接寫入電腦的電子零件之中,而不是儲存於硬碟(hard disk drive)之內。

第二,為一個硬件設計和編寫「韌體」時,會直接受制於,該個硬件自身的設定和侷限。

第三,一個硬件出廠前,會安裝好「韌體」。自此以後,就很少會修改更換,因為那相對複雜困難,而且通常也不會帶來明顯的好處。
