兩次測驗

有兩次測驗.

第一次測驗前沒有溫習.

第二次測驗前溫了習.

不知怎樣, 第二次的成績反而差過第一次.

.

為什麼溫了習反而會得較低分?

第一, 這種情況不是每次都發生. 最多只能說, 有時溫了習會較低分, 有時溫了習會較高分. 不能說, 任何情況下溫習都會降低分數.

哪為什麼有時溫了習反而會得較低分?

.

第二, 事物通則: 物極必反, 過猶不及. 任何事情做得過量就會有反效果. 溫習適量, 對成績有提昇. 溫習過量, 對成績有傷害.

為什麼呢?

溫習是建立知識的過程, 好像建立一幢大廈一樣. 最初是起鋼筋. 當大廈已經有足夠鋼筋時, 你就應該建外牆. 建了外牆後, 就要加內部結構, 如此類推.

最後, 大廈內部要有空間給人住, 給人活動. 大廈的內部如果都有鋼筋的話, 只會破壞大廈應有的格局, 阻礙住客的活動.

溫習適量, 意思是(該次測驗的)知識結構已經建立好. 建立好了, 就應該停止”輸入資料式的溫習”(鋼筋). 改為鞏固腦有內已有的知識(加外牆). 例如: 做練習, 背誦重要的句子, 或背誦公式等. 甚至只是”休息”, 讓大腦(潛意識)自動整理已有的知識.

測驗時, 大體有兩類題目.

第一種是書中已有的東西, 考驗你記憶力, 考驗你有沒有溫習.

第二種是書中沒有明言的東西, 考驗你的創意, 考驗你能否將知識融會貫通.

.

溫習過量的話, 會破壞知識應有的格局, 阻礙思考, 令創意沒有發揮的空間.

遇到第二種題目的話, 你將會未必想到解決的方法.

.

哪怎樣可以知道溫習是過少, 適量, 還是過多?

你自己會自然知道的:

當你越溫越自信時, 你就應該繼續溫.

當你越溫越惶恐時, 即是你的溫習已經過量. 你的溫習正在破壞你剛建立好的知識結構. 你應該停止.

.

第三, “有心栽花花不香, 無心插柳柳成蔭.”

想像以下兩情況:

一. 當你沒有溫習的情況下去測驗, 不祈望高分, 只求盡力而為, 拿得一分得一分.

二. 當你有溫習的情況下去測驗, 祈望高分.

比較這兩種情況, 有些時候(不是任何時候), 第一種情況會得到較高分.

原因有二:

一. 當你祈望一定要高分時, 你會較緊張, 創意會較低.

二. 不懂權衡輕重: 有時祈望每題也十全十美. 你會花過多時間去做開頭的題目, 力臻完美, 導致沒有足夠時間做其他的題目.

.

.

哪應該怎樣做才達致最高分數?

不要第一,  二種情況, 要第三.

一. 當你沒有溫習的情況下去測驗, 不祈望高分, 只求盡力而為, 拿得一分得一分.

二. 當你有溫習的情況下去測驗, 祈望高分.

三. 當你有適量溫習的情況下去測驗, 不祈望高分, 只求盡力而為, 拿得一分得一分.

.

要達致這種心理狀態, 不一定很容易. 要反覆練習.

Star Trek

Where No Man Has Gone Before

.

The show’s cultural influence goes far beyond its longevity and profitability. An entire subculture grew up around the show and, anecdotally, there are indications that Star Trek has influenced many people’s lives. This is apparent from the reported testimonials of people, such as scientists and engineers, who claim that their professional and life choices were influenced by Star Trek.

睡眠癱瘓症

.

軀體在人睡眠時進入麻痹狀態是一個必要的過程,以避免人在做夢時對軀體進行真正的移動。當身體已經在這個階段,但腦的一部分還處於完全工作狀態時,會發生睡眠癱瘓。睡眠癱瘓常伴有恐慌發作,因為人還處於有意識的狀態。同時伴隨聽覺和視覺上的幻覺,對於睡眠癱瘓也是很典型的,然後漸漸進入「夢境」。通常還會有「假醒」,即人醒過來,發現自己原來還在夢裡,現實中也還在睡眠。這樣的「假醒」通常會多次重複,伴隨的還有來自於對這種無終止重複的恐懼。通常是可以打斷這種重複與麻痹的,如通過試着對小指的移動等。

Freefall

.

* We’re in a freefall into future. We don’t know where we’re going. This are changing so fast, and always when you’re going through a long tunnel, anxiety comes along. And all you have to do to transform your hell into a paradise is to turn your fall into a voluntary act. It’s a very interesting shift of perspective and that’s all it is… joyful participation in the sorrows and everything changes.

PART ONE: The Adventure of the Hero

Chapter I: Departure

* 1. The Call to Adventure

The adventure begins with the hero receiving a call to action, such as a threat to the peace of the community, or the hero simply falls into or blunders into it. The call is often announced to the hero by another character who acts as a “herald”. The herald, often represented as dark or terrifying and judged evil by the world, may call the character to adventure simply by the crisis of his appearance.

* 2. Refusal of the Call

In some stories, the hero initially refuses the call to adventure. When this happens, the hero may suffer somehow, and may eventually choose to answer, or may continue to decline the call.

* 3. Supernatural Aid

After the hero has accepted the call, he encounters a protective figure (often elderly) who provides special tools and advice for the adventure ahead, such as an amulet or a weapon.

* 4. The Crossing of the First Threshold

The hero must cross the threshold between the world he is familiar with and that which he is not. Often this involves facing a “threshold guardian”, an entity that works to keep all within the protective confines of the world but must be encountered in order to enter the new zone of experience.

.

.

Chapter II: Initiation

* 6. The Ultimate Boon

The hero is now ready to obtain that which he has set out, an item or new awareness that, once he returns, will benefit the society that he has left.

.

.

Chapter III: Return

* 1. Refusal of the Return

Having found bliss and enlightenment in the other world, the hero may not want to return to the ordinary world to bestow the boon onto his fellow man.

* 4. The Crossing of the Return Threshold

The hero returns to the world of common day and must accept it as real.

* 5. Master of the Two Worlds

Because of the boon or due to his experience, the hero may now perceive both the divine and human worlds.

* 6. Freedom to Live

The hero bestows the boon to his fellow man.

中道

.

.

中道,簡單而言是不苦不樂(不追求痛苦、不追求快樂)的修行方法。

中道的最初靈感,是佛陀在長期苦行苦修後卻覺得一無所獲,而在近河的地方打坐時,聽到河船上的人唱?:「琴弦太鬆、太緊都無法彈出悅耳的聲音。」佛陀以此進行推思,凡夫俗子追求慾望、快樂,死後將墜入地獄,而苦行僧的森林苦行雖可在死後生為天人,得到比人世間更好的快樂,但福報用盡也依然要離開天界,再次輪迴,因此認為不該在苦樂中計較,以不追求痛苦、不追求快樂的方式修行,才有可能擺脫生老病死與六道輪迴。
