Trans-Planckian problem

Mute Hole 2

The trans-Planckian problem can be conveniently considered in the framework of sonic black holes, condensed matter systems which can be described in a similar way as real black holes. In these systems, the analogue of the Planck scale is the interatomic scale, where the continuum description loses its validity. One can study whether in these systems the analogous process to Hawking radiation still occurs despite the short-scale cutoff represented by the interatomic distance.

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.

歸納筆記 2.1

這段改編自 2010 年 6 月 8 日的對話。

這個方法,只作「娛樂」之用。考試時,就應該用剛才的速成方法,以節省時間。又或者,兩個方法也用,以作驗算。

(HYC:但是,這一題我只會想到正常的,慢一點的方法。)

那你又毋須要求,自己會發明到那個速成方法。你現在試試用一次,然後把它記載於「魔法筆記」之中,考試時就自然會記得,因為根據「魔法筆記」的設計,你除了在平日要背誦外,在臨考試前的半小時,還要高速瀏覽一次,提一提醒自己。

(CYW:但是,我一到考試臨場緊張時,很多時也會忘記,必須的技巧。有沒有方法可以記得呢?)

我不斷推介的「魔法筆記」方法,正正是要徹底解決這個問題。而這個方法的重點是,必須有系統地,長期反覆背誦,考試必須的知識和技巧。試想想,如果你有在臨考前背誦「魔記筆記」,又怎可能在考試時「臨場遺忘」,內裡記載的常用技巧呢?

你們可能會問:「又怎可能在半小時內,把『魔法筆記』的所有內容,都閱讀一次呢?」
