LYK WTH,
2nd time someone took my laundry basket in 2 weeks -.-, seriously, who are the people so pitiful that they have to take other people's laundry baskets?

Besides the serious stuff, we learnt three important things ytd in physics O.
1) How to create a black hole.
"Suppose we have a rice cooker, and we heat the rice cooker up by T kelvins. Then the new volume of the rice cooker will be V2 = V1(1+γΔT). Where γ is the volumetric thermal expansion coefficient. So applying the same equation, when the rice cooker cools down, we'll get V3 = V2(1-γΔT) = V1(1-γ2ΔT2), which is smaller than V1. So, if you have a rice cooker, and you heat it up and cool it down, and heat it up and cool it down, and heat it up and cool it down, and heat it up and cool it down... and after a few months when you come back, and.... "Hey... where is my rice cooker.....?" "
*Of course something screwed up here.
2)Second law of thermodynamics.
"Some people say that the second law of thermodynamics contradicts the theory of evolutions. In the theory of evolution, man gets more handsome, and this means entropy decreases... But, if we look at the second law, we see that it only says that the total entropy of the universe must increase. So, in this case, only the entropy of the system decreases, so the law still holds, since the entropy of environment increases, since when people get more handsome the more chaotic it is. So..., the point here is that if you want to save the environment, if you want to go green....... "
3)Third law of thermodynamics.
This one is not by the teacher, so its short(and lame).
The third law of thermodynamics is a pessimistic one, since it implies that nothing will ever by OK. (zero degrees kelvin)
For some reason we were all super hyper after the lesson, and Yu Jia decided to take the lift even though she lives on the second floor.
So after she left Jee Hyun was saying "At least I'm on the third floor...".
Then Wayne responded, "EH, my floor is 22 leh."
Yu Jian, "Ya... totally (-.-), mine 23 you know."
And after that we went nuts and got everyone's floor in binary numbers
1st storey (Phan, she took stairs) = 20
2nd storey (Yu Jia) = 21
3rd storey (Jee Hyun) = 22+20
4th storey (Wayne) = 22
6th storey (Timothy) = 22+21
8th storey (Me and Yu Jian) = 23
12th storey (Gloria) = 23+22
*Of course, ur susposed to be able to express all numbers wif binary nums
Aww, thats what you get when you put a bunch of physics O students in a lift anyway.
Oh and
"I'm gonna go find YOU and have lots of fun! No not Phan, not interested." - Yu Jian
(There's a guy called Ryan You in our cluster and a girl called Phan (pronouned 'fun') in our mentor group.)

Get a pair of earphones and a styrofoam cup. Make a small hole near the bottom of the cup with ur earphones' plug and leave the plug there. Wear ur earphones and use the thing as a sethescope. You can like totally hear your own heartbeat.
*btw Timothy trolled abt a dozen ppl, including a teacher with this, mass trolling hahahaha

list of epicness
1)I think there are more mosquitoes at home than in boarding -.-.
(Lame math joke: What do you get when you cross a mountain climber and a mosquito?)
2)WEDNESDAY FREGGIN 9HR LESSON IS CANCELED. yeah..... coz of lesson swaps hehe
3)I have no lessons at all today, since Mr Soh is on leave for physics H and Mr Ricardo didn't want to have extra physics o lessons on valentine's night lololol.
4)Theres a fatal error in the physics H notes, which of course would mean that all the assignment answers will hav weird values tat is simply incorrect. I read the textbook, I realised how to fix it, but I suck at math..... So.... someone help me with this.
∫ 2πhc2/(λ5(ehc/(λkBT)-1)) dλ = ƒ(λ,T), find ƒ(λ,T)
where,
h = planck's constant
c=speed of light
kB = boltzman constant
e=2.71.....
T=temperature(constant)
λ = variable (wavelength)
(∫=integrate,π = Pi), btw
And er, for the indefinite integral, constant=0. GLHF
(I don't even think this gives the correct answer for the assignment, but hey, its a challenge)

lololol, apparently there are exchange programs that you have to sign up thru facebook. i'm not gonna care, i'll rather walk into the college counsellor's office and sign up directly if i really wanted to go rather than create a account hehe.....
.... it hasn't been too long, but i dun think i should continue to do it like this........

lets start wif ytd:
I was still in school in the morning, and there's a 1 hr break between lessons and the CNY concert, so I went to the music room to chill (my friends plays the instruments, i have no affinity with music.) Anyway, timothy got bored on the piano and started playing with the guzheng (playing with as in guitar strum and stuff). I think he hit the resonance of the chair i was sitting on, coz it suddenly started to vibrate like mad, lololol.
Theres 11 ppl at home for dinner ytd xD,(aunts and cousins came from china) , dam noisy. I managed to send a sms at exactly 12am, been trying and phailing for years. And the CCTV CNY concert was kinda boring, so i was playing majong hehe.
Went to the zoo juz now, at least it didn't rain like last time -.-, horrible experience. Ah well.
....... I decided to settle it.... to be honest it's not the first time i tried, but hopefully it'll be the last time.
