反白論前傳:尼采篇 7
樹要往高往上往光輝處生,根要往下往深往黑暗處長。
唯有經過地獄的磨難,才有創造天堂的力量。

先決程式 3
情形就好像打字一樣。打字快的原因是,你打完一個英文字母,才打下一個;而不是同一刻打超過一個字母。如果你企圖同一刻打超過一個字母的話,你會打錯字。字母的次序錯了的話,時間上會得不償失。

Hawking was asked about his IQ in a 2004 newspaper interview, and replied, “I have no idea. People who boast about their I.Q. are losers.”

(CN:考完會考後,我想你教我 presentation(表達、說話、演講、教學)的技巧。)
我現在可以先講一些 presentation 的基本原理給你聽。
首先,說話要 in series(串聯),不要 in parallel(並聯)。你要說完一句說話,才開始說下一句說話。你要講完一個 point(要點),才講下一個 point。千萬不要企圖在同一刻時間中,講超過一句說話。亦千萬不要企圖在同一句說話中,包含超過一個要點(point)。
簡言之,說話要有條理。

String theory is the most conservative among all the extensions of quantum field theories that go beyond the standard framework of QFT.

I think the solution is to work in the other direction. Instead of working back from a goal, work forward from promising situations. This is what most successful people actually do anyway.
In the graduation-speech approach, you decide where you want to be in twenty years, and then ask: what should I do now to get there? I propose instead that you don’t commit to anything in the future, but just look at the options available now, and choose those that will give you the most promising range of options afterward.
It’s not so important what you work on, so long as you’re not wasting your time. Work on things that interest you and increase your options, and worry later about which you’ll take.
Suppose you’re a college freshman deciding whether to major in math or economics. Well, math will give you more options: you can go into almost any field from math. If you major in math it will be easy to get into grad school in economics, but if you major in economics it will be hard to get into grad school in math.

讀心術 8.3
這段改篇自 2010 年 3 月 25 日的對話。
不幸地,我發現有很多人也不只是「忘恩」,而且是「負義」。我對他們好,他們就千方百計攻擊我。我越對他們好,他們攻擊我的程度就越嚴重。
(CN:這個對。我的上司對下屬很好,幾乎視之為親人。但是她的下屬往往不會知恩圖報,反而會離她而去,轉投我上司的競爭對手。還有,不單一個下屬是這樣:這個情況不斷發生。聽下來很奇怪。)
當我們平時說:「理論是這樣;實際不是這樣」時,即是話,我們的「理論」錯了。我們只能修改「理論」來令它符合「實際」,而不能要求「實際」遷就「理論」。
你覺得很「奇怪」,是因為你仍然假設了「大部分地球人是理性和善良的」。如果你知道和體會到這個理論是錯的,而轉用一個符合實情的理論時,你就不會再覺得「奇怪」。如果你的理論是「大部分地球人是瘋狂的怪獸」時,你就會覺得,你所觀察到的「忘恩負義」現象是「自然」的。當然,「自然」不代表「美好」。

Bayesian probability is one of the most popular interpretations of the concept of probability. The Bayesian interpretation of probability can be seen as an extension of logic that enables reasoning with uncertain statements. To evaluate the probability of a hypothesis, the Bayesian probabilist specifies some prior probability, which is then updated in the light of new relevant data. The Bayesian interpretation provides a standard set of procedures and formulae to perform this calculation. Bayesian probability interprets the concept of probability as “a measure of a state of knowledge”, in contrast to interpreting it as a frequency or a physical property of a system.

(安:又例如,「中國特色社會主義」其實是 Virtual Machine(虛擬機器)的一個大例子。
中國想實行「資本主義」。但是,當年要一下子更換掉「社會主義」硬件並不可行。所以,中國在已有的「社會主義」硬件上,安裝了「中國特色」Virtual Machine。以後,就可以在「中國特色」這個 Virtual Machine 上,運行「資本主義」程式。)

讀心術 8.2
這段改篇自 2010 年 3 月 25 日的對話。
後來,我發現這個想法,只有在少部分情況下是正確的。大部分情況下,這個想法都與事實不乎。有很多(例如)沒有禮貌的人,我越了解他們,越發現他們的內心深處,比表面還要邪惡,完全否定了我「人心的最深處是善良的」的假設。
有時,別人「忘恩」,我會有少許不開心,但至少不會難過傷心。如果我幫了一個人,他「謝謝」也沒說就離開了的話,至少他不會攻擊我。
不幸地,我發現有很多人也不只是「忘恩」,而且是「負義」。我對他們好,他們就千方百計攻擊我。我越對他們好,他們攻擊我的程度就越嚴重。
(CN:這個對。)
