If a = b
a² = b²
a² - ab = b² -ab
a (a - b) = b (b - a)
a (a - b) = -b (a - b)
Cancel out (a - b) both side, we get..
a = -b
Huh?

At Long Last
I came back. To the place I created. Yet not knowing what I should do or say. That was really ironic, huh?
More videos then, I think.
Love this :) And the music. I had nearly forgotten that this game is based on a love story. IMAGINE THAT. All I remember about this game is demon slashing swt.
Be patient until around 1:30. Thats where the narrative starts.
"That arrogant kid possesses d-d-demonic powers!!" My favourite part lols.
P/s I am particularly surprised at all those comments in my previous posts. But all they did was to make me uneasy for dunno what reason.

WOW.
The following concerns a question in a physics degree exam at the University of Copenhagen:
"Describe how to determine the height of a skyscraper with a barometer."
One student replied:
"You tie a long piece of string to the neck of the barometer, then lower the barometer from the roof of the skyscraper to the ground. The length of the string plus the length of the barometer will equal the height of the building."
This highly original answer so incensed the examiner that the student was failed immediately. He appealed on the grounds that his answer was indisputably correct, and the university appointed an independent arbiter to decide the case. The arbiter judged that the answer was indeed correct, but did not display any noticeable knowledge of physics. To resolve the problem it was decided to call the student in and allow him six minutes in which to provide a verbal answer which showed at least a minimal familiarity with the basic principles of physics. For five minutes the student sat in silence, forehead creased in thought. The arbiter reminded him that time was running out, to which the student replied that he had several extremely relevant answers, but couldn't make up his mind which to use. On being advised to hurry up the student replied as follows:
"Firstly, you could take the barometer up to the roof of the skyscraper, drop it over the edge, and measure the time it takes to reach the ground. The height of the building can then be worked out from the formula H = 0.5g x t squared. But bad luck on the barometer.
"Or if the sun is shining you could measure the height of the barometer, then set it on end and measure the length of its shadow. Then you measure the length of the skyscraper's shadow, and thereafter it is a simple matter of proportional arithmetic to work out the height of the skyscraper.
"But if you wanted to be highly scientific about it, you could tie a short piece of string to the barometer and swing it like a pendulum, first at ground level and then on the roof of the skyscraper. The height is worked out by the difference in the gravitational restoring force T = 2 pi sqrroot (l/g).
"Or if the skyscraper has an outside emergency staircase, it would be easier to walk up it and mark off the height of the skyscraper in barometer lengths, then add them up.
"If you merely wanted to be boring and orthodox about it, of course, you could use the barometer to measure the air pressure on the roof of the skyscraper and on the ground, and convert the difference in millibars into feet to give the height of the building.
But since we are constantly being exhorted to exercise independence of mind and apply scientific methods, undoubtedly the best way would be to knock on the janitor's door and say to him 'If you would like a nice new barometer, I will give you this one if you tell me the height of this skyscraper'."

有时候听得多，看得多了，会颇有感触，前一刻好像对人生有更深刻的了解似的，一转身，经验还来不及沉淀，转换成在人生大道前进的资本，就忘得一干二净。
也许这也是成熟的一个过程。
那一刻，你愿意用心去琢磨，能把握得住，感悟越多，思想就越成熟。
也许这也是成熟的一个过程。
那一刻，你愿意用心去琢磨，能把握得住，感悟越多，思想就越成熟。
你放任它离去，不去留意，不去关心，心灵就会失去磨炼的机会，也许你就会像个永远长不大的孩子，思想像一块未经雕刻的璞玉，保留赤子之心，永远发光发热。
As the saying goes, growing old is inevitable, growing up is optional. Do you really want to grow up?

Now I am looking for a video about life cycle of stars for my assignment.
You know? My first ambition ever is to become an astronomer. 天文学家。
I was once fascinated by the universe, the stars, planets, galaxies, nebula, power of black hole that could bend even light, the secret of space and time, 相对论 (well i guess this is physics. But the universe is all about physics aren't it?) and all of which only God could create.. 宇宙，浩瀚而细腻，无垠无穷无尽。
But unless I could get into NASA i am going to say goodbye to this career. (Edwin wants to be one, though)
曾几何时，过了会做梦的年龄？
星辰的年龄是以亿万为单位，与人类相比可说是永恒的存在。我们实在是渺小啊＝＝
然而永恒太长太长了，把握不住那是人之常情，但是刹那的时间。这样短暂，却能把握得住的人，又有几个呢？刹那都把握不住，如果把握住永恒？
