塗改風暴 3.3

這段改編自 2010 年 5 月 1 日的對話。

（CKY：那麼嚴重？）

當然是嚴重啦！試想想，「僅僅合格」和「僅僅不合格」，只是一分之別。

所以，千萬不要因為覺得自己寫字寫得不美觀，而把字劃掉再寫；除非，你發現剛才寫的字寫得不夠清楚。例如，有一些人會把「0」字寫到好像「6」字似的。那是大忌，應該立刻修正。

Control the universe

Posted on by

“Emptiness is everywhere and it can be calculated, which gives us a great opportunity. I know how to control the universe. So tell me, why should I run for a million?” he told the Russian newspaper Komsomolskaya Pravda.

Anti de Sitter space 3

Posted on by

de Sitter Space distinguished from spacetime in general relativity

Fundamentally, the key concept behind the idea of de Sitter space is that it involves a variation on the spacetime of general relativity in which spacetime is itself slightly curved even in the absence of matter or energy.

An inherent curvature of spacetime even in the absence of matter or energy is another way of thinking about the idea of the cosmological constant in general relativity. An inherent curvature of spacetime and the cosmological constant are also equivalent to the idea that a vacuum (i.e. empty space without any matter or energy in it) has a fundamental energy of its own.

de Sitter space can also be thought of as a general relativity like spacetime in which empty space itself has some energy, which causes this spacetime (i.e. the universe) to expand at an ever greater rate.

塗改風暴 3.2

現在不是書法比賽。記住，考試時，字體毋須優美，但是一定要清楚。

（CKY：這是我的個人感受。寫字寫得不美觀時，我會把字塗改掉，重新再寫一次。）

千萬不要那樣。這個壞習慣，隨時可能誤你一生。

試想想，可能因為這個壞習慣，你在某一科考試時，總共浪費了幾分鐘；可能因為那分鐘，你在該科損失了幾分的分數；可能因為那幾分，你在該科得不到你想要的成績等級；可能因為該科失手，你沒有足夠的成績升讀中六，又或者升讀時選不到你原本想讀的科目，大大減低了你升讀大學的機會。那樣，足以令你斷送一生的幸福。

（CKY：那麼嚴重？）

當然是嚴重啦！試想想，「僅僅合格」和「僅僅不合格」，只是一分之別。

On Keeping Your Soul

Posted on by

The great challenge at the beginning of ones career in academia is to get tenure at a decent university. Personally I got tenure before I started messing with quantum gravity, and this approach has some real advantages. Before you have tenure, you have to please people. After you have tenure, you can do whatever the hell you want – so long as it’s legal, and so long as your department doesn’t put a lot of pressure on you to get grants. (This is one reason I’m happier in a math department than I would be in a physics department. Mathematicians have more trouble getting grants, so there’s a bit less pressure to get them.)

The great thing about tenure is that it means your research can be driven by your actual interests instead of the ever-changing winds of fashion. The problem is, by the time many people get tenure, they’ve become such slaves of fashion that they no longer know what it means to follow their own interests. They’ve spent the best years of their life trying to keep up with the Joneses instead of developing their own personal style! So, bear in mind that getting tenure is only half the battle: getting tenure while keeping your soul is the really hard part.

Chrono Trigger 3

Posted on by

.

Masato Kato confirmed that Cross featured a central theme of parallel worlds, as well as the fate of Schala, which he was previously unable to expound upon in Chrono Trigger. Concerning the ending sequences showing Kid searching for someone in a modern city, he hoped to make players realize that alternate futures and possibilities may exist in their own lives, and that this realization would “not … stop with the game”.

Intellect 3

Intellect is invisible to the man who has none.

— Our Relation to Others, § 23

– Arthur Schopenhauer

Intellect is invisible to those have none.

（安：那是什麼意思？）

不聰明的人是不會感受到，聰明的東西究竟聰明在什麼地方。

假設有一個平庸的人，他的智力只有 100 個單位。假設有一篇上佳的文章，它的內容「智力」有 150 個單位。如果你把那篇上佳文章給那個平庸的人的話，他會覺得，那篇文章只值 100 個單位。他不會感受到那額外的 50 分在哪裡，因為以他自己的智力，不足以領會那高於他智力的 50 分。他會覺得，那篇上佳文章是沒有價值的。

而最麻煩的地方是，他因為沒有能力領會那高於他智力的額外 50 分，他根本不會覺得，自己的智力低於那篇文章。結果，他不單不會質疑自己的智力，反而只會責怪那篇文章的作者，浪費他的時間。

Ra’s al Ghul

Planned cast

Bale said he would return if Nolan did. Aaron Eckhart had expressed his enthusiasm to return for a sequel if asked, although he later stated Nolan verified that his character, Harvey Dent, is dead. Nolan confirmed that the ensemble cast from the first two films will be returning. Tom Hardy and Anne Hathaway have been cast as Bane and Selina Kyle. Juno Temple has been cast in a role described as a “street-smart Gotham girl”. Josh Pence was cast as a young Ra’s al Ghul, with his scenes to take place thirty years before the events of Batman Begins. Nestor Carbonell is in negotiations to reprise his role as Mayor Anthony Garcia. Joseph Gordon-Levitt has been cast as John Blake, “a Gotham City beat cop,” along with Marion Cotillard, who will be portraying Miranda Tate, “a Wayne Enterprises board member eager to help a still-grieving Bruce Wayne resume his father’s philanthropic endeavors for Gotham”.
