自愿要做的事，就该尽心去做。
在途上遇到了不顺心的事，也不能埋怨别人。
因为那始终都是你自愿要做的。
自愿要帮助他人，就该尽心去帮。
不能抱着“现在是我在帮你，所以你不该要求太多”的态度。
因为答应帮助他人，虽然不算是一场交易，但也算是一种承诺。
I calculated and realised that I have over $100 in credit!
"Paying first" for birthday presents
Dilemma: It's very paiseh to 开口要钱 when everyone is enjoying himself/herself at a birthday party. In fact, it's very hard to put across the statement "You owe me money" in a nice way. But you have to get your money back!
Solutions:
1. Ask a good friend to collect the money on your behalf, because the good friend will be buay paiseh to help you demand for the owed money. Haha. Thought up by Sa.
2. 厚着脸皮跟人要钱。There's really no need to 厚着脸皮 lah. You have the right to ask for the money mah.
So I'm going to be really thick-skinned in asking for money the next time I pay for a present!
I shall take away all the mathematical jargon and explain it not-very-accurately. P and NP are sets of optimization problems, or problems in which you minimize or maximize something. P = NP? asks whether having a (fairly efficient) method to solve a problem is equivalent to having a (fairly efficient) method to check if there really is a solution when you know that there is a solution.
P = NP? is one of the seven Millennium Prize Problems which were proposed as the few most important questions in maths. Some of them, including P = NP?, haven't been solved and there's a $1 000 000 award for the first person who solves each question.
My interest in this question wasn't because of the solution to it, but because of the nature of the question. It doesn't sound entirely mathematical, does it? My search of this question on Wikipedia brought me to another theorem which, together with P = NP?, was mentioned in Basics of Maths - Gödel's first incompleteness theorem. This theorem suggests that there are things in maths that cannot be proven.
I thought to myself, the things mathematicians do at higher levels are really mind-boggling. But somehow, the theories they prove come to find use in today's techonology. Sugoi.
There was a question from yesterday's tutorial where the lecturer went around to ask if anyone knew how to do it. Everyone was shaking his/her head, but when the lecturer finished his round of asking, he said,
"That guy knows the answer." Wah..
Then the guy spoke. "I don't know." ?!
The lecturer explained, "The correct answer is, there is no answer. Don't write anything else if you're asked this question in the exam. You'll be marked wrong."
This is.. maths?
