The Phone Book

In physics, Gravitation is a very important reference book on Einstein’s theory of gravity by Charles W. Misner, Kip S. Thorne, and John Archibald Wheeler. Often considered the “Bible” of General Relativity by researchers for its prominence, it is frequently called MTW after its authors’ initials, or “the Phone Book” due to its immense size. It was published by W.H. Freeman and Company in 1973. The book, a massive tome of over 1200 pages, covers many aspects of the General Theory of Relativity and also considers some extensions and experimental confirmation. The book is divided into two “tracks”, the second of which covers more advanced topics for more capable or determined students. MTW uses the -+++ metric convention. The book is famous/infamous for its use of boxes to add supplementary substance to the already thorough main text.

Being right

Inactivity as intelligent

* We don’t get paid for activity, just for being right. As to how long we’ll wait, we’ll wait indefinitely.

間時間表(前傳)

Half an Hour 2.5

Timetable for high school study 10.4

這段改篇自 2010 年 2 月 7 日的對話。

Monday Tuesday Wednesday Thursday Friday

以上就是「自動時間表」的「基本設定」。在「基本設定」之上,你需要再加一些重要細節。

3 hours Physics

一個正常人在一般的情況下,很難可以連續專心思考三小時。所以,我建議你把「三小時的一格」間開(分割)成「六格半小時」,然後每次只要求自己連續集中思考半小時。

30 minutes Physics

如果你不用這個方法的話,那三個小時通常也會這樣度過:第一格用來去洗手間;第二格用來去冰箱拿東西吃;第三格用來接電話;第四格用來執拾書桌;第五格用來內疚;第六格用來傷心。

30 minutes 去洗手間
30 minutes 去廚房
30 minutes 接電話
30 minutes 執拾房間
30 minutes 內疚
30 minutes 傷心

(LWT etc:哈哈 … )

你們笑,即是有共鳴。有共鳴,即是平時也是這樣浪費時間的。那又毋須過份責怪自己,因為年青人都是那樣的。我自己年青時,也是那樣的。

要盡量避免這個情況的話,你可以用這個「程式」(機械程序):

第一,把「三小時的一格」間開成「六格半小時」,每次只要求自己連續集中思考半小時。

第二,每格半小時後,都應該有 5 分鐘的休息。

第三,在每一格半小時內,不可以做溫習以外的任何其他東西,除非事關重大,例如火警逃生。

第四,溫習以外的任何其他事情,例如 去洗手間、去廚房、接電話、執拾房間、內疚 和 傷心 等,應該堆積在那些 5 分鐘方格內,一次過完成。

第五,在每一格半小時內,不可以看時鐘或手錶。你看時間的話,即代表你已經分了心。不看時鐘手錶,又怎樣可以知道「已經夠半小時」呢?你應該用鬧鐘鬧錶的響鬧聲,作為報時信號。
