"I really think you should go and wash your face."
--------------quoted from my maths teacher
yes, i admit that i fall asleep during maths lesson, and its not because i lacked sleep the previous day either. a few possibilities are: 1) i was tired after my napfa test earlier in the morning and cannot stay awake. 2) i suck thus i could not concentrate during maths lessons.
in which option (2) is more likely, as anyone who bothered to read my blog would noe that i nearly always fall asleep during maths lesson, partially cuz the lesson was just...hypnotizing by itself that i could just doze off. even after the lesson ended and it was chinese i was still dam sleepy, so mayb cuz of the napfa test.
since i was so sleepy, my brain cells didn bother to think of anything fantastic or nice sounding to write about today. except that i passed my napfa and might get a gold or a silver. then tmr i need to stay back for some lame cip thing which is just, well, cip.

Quote of the day:
"Shut up, bitch"
--------quoted from ***** (sensored to protect privacy)
ok moving on to the topic of desperation. in this kind of high-muggery society AKA HCl (hydrogen chloride). (ppl of the group, u noe wat i mean), everyone is having an extreme stressed and sometimes f!!ked up life, working through (compared to eating through) homeworks, ace, projects, and sometimes extra little something from kind teachers. thus came in the time when the brain became overloaded, resulting in massive "disturbia" of the mind, AKA emo+despo, where people will shout out random lines of words unintentionally and unconsciously. thus there are times, although it doesnt happen in HCl(g), in which some people will do strange things to let their brains acknowledge the horrible truth of the world, which includes take a nice, rusty blade off a penknife, slide it open, put it below the palm, and make a sudden movement that will usually result in fluids rich in red blood cells, white blood cells and plasma to flow out. (u get wat i mean) more extreme cases involve taking a lift and enjoy the scenary of the topmost storey of the HDB flat and then experience the feeling of bunjy jumping, only it lasts shorter and sometimes hurts for a few seconds.
so the main point after all is, how do u relieve the enormous amount of pressure within u? although i myself often suffers from "disturbias", especially before a maths test, i do have some ways of relieving the "dark cloud of negative emotions".
Step 1: take a pillow, put ur two hands around the pillow and push them inwards. if done on a real persons neck u will usually get reactions such as weird sounds coming from the throat, parts of ur body hurting after getting kicked by a pair of legs, two hands suddenly grabbing ur hands and attempting to fling them off.
Step 2: take deep breaths. usually the "deep" is measured by how much air ur lungs can contain. of course if u are interested to take fast and continuous deep breaths u would usually temporarily find urself unable to control ur fast pace, in a process also known as hyperventilation.
Step 3: do something that makes u happy. normally it involves doing things to objects around u that induces pleasure to urself (dun get me wrong). but usually this results in some member of the family coming out of the room and start shouting at u to continue doing ur work, so in the end u only got more angry.
Step 4: do something that makes u even more angry. it usually involves doing ur least favourite homework (for me its maths) for a few hours none stop. then immediately go on to ur second least favourite work and the process continues, until some member of ur family begs/forces/commands u to go for ur dinner. the plus side of this is that u get the triumphant feeling that u ARE important after all. the down side is for a couple of hours u will be suffering from severe disturbia which usually ends up with u throwing things about, tearing things, do the stupid things in STEP 1, or explodes.
so here is the end of my little daily quote. wait for tmr to find another interesting quote.

was just tagging at jy's blog about how dead her blog is then realised my posts were also outdated. (somewhat) so i took out my brain and cleaned it, in order to make it stainless for my blog post.
this few days are completely NOT IN MEMORY. due to the fact that they are so boring and so everyday life like that my brain does not find the need to record such trivial everyday hci life. the only thing it does record is about how busy i felt when projects day start to get nearer and theres a maths test tmr. then here i am doing my chinese homework and writing this post as well. i suck at multi-tasking so its highly probably i will either finish this before the homework, finish the homework before this post (around 10% probability, a high percentage seeing how sian i was), did not finish either of the task or finish both after a longer time.
yesterday i was chionging wtf so much that i realised i only played one match of standard game. then here i am writing this post SECRETLY, seeing that my dad may not even allow me to post blogs without completing my homework beforehand. and of course he was talking about homework---->sleep (skipping "play") sequence for now. its highly likely that he would kill me if i told him i still had my projects day powerpoint to do and of course keith is not free tmr morning to do his part, so daniel and i had to tank his area. i really feel like sleeping after my chinese homework, cuz i dun feel like doing something on the com as it means no music for more than 2 hours. (since mom is sleeping, if its some paperwork it would be a different story, as the handphone comes in play)
so most of the time i was questioning myself the reason for my com playing time to be restricted to 5 hours IN THE WEEKEND, and realised it was due to the fact of my this terms msg, a pathetic 2.67. ( to make matter worse im onli like near the middle-top of the class, which gives my parents, my dad mainly, the reason to restrict my time, due to the "Good and Bad" paradox, which i will explain next.)
now moving on to the "Good and Bad" paradox, which i named it myself lolz. its a paradox (go check dictionary if u dun noe) in which the parent will compare or as some say "give example" of other ppl's results with their own child's results, and give a conclusion in which whether the (look back to see any movements from within the room) "example"s result is good or bad, would give the same end product. The following is an example:
Parent: Why u play so long, result very good is it?
Child: yes, i find my result acceptable.
P: who is the highest in ur class?
C: XXX. he got 1.5 and he played more often than me.
P: see? u only 2.0. XXX is so good, thats why he could play.
C: then wat about YYY. he onli got 2.5, but he still played more time than me!
P: he played so long until his results drop, thats y u cannot be like him, so u also must play less.
C: ...........................
so the main point is: when the child came up with a classmate whos result is better than his and played longer than him, the parent could say since XXX has such good result, thus he could play longer. then when the child came up with YYY who played longer but has worse results, the parent could say that thats y their child could not play so long, since YYY played so long until his result dropped. alternatively, the child could came up with XXX in the next term, and say how his grade dropped but he still played so long. however, the parent could easily rebutt with "because he played so long in term 1, thats y his result dropped in term 2". so no matter wat the child say, he will still be at the losing end. the only way is to compare with someone who has the same grade as the child, but the parent could come up with a few alternatives of reasoning as well: 1) compare ZZZ's other activities such as music lesson, third language, etc. 2) compare the exact marks ZZZ got with the child. for example, the child got 91/100 while ZZZ got 97/100. 3) use the "ulti" also known as "ZZZ's parent have different way of bringing up ZZZ. we are ur parents, (this is for ur own good) u listen to wat we say. usually this only comes up when the parent ran out of reasons and was either pushed into a corner by their own reasons or by their child's reasons, thus they only say it at the end. though there are cases in which they say it at the begining as the "initiating skill", so all in all,
PARENTS WIN
(our champion has fallen)
woho i could actually type so much for my post its really the first time. possibly cuz emotions invokes products. well well i will try to find some other things to write about parents next time

*hurray today is the new term of new excitements and joy. YES JOY.
so mainly today was quite slack, cuz its first day of school. well well, too bad for those ppl in bsp who got a few hundred pages worth of tutorial for their BSP topic. but then first day got chinese summary, but then compared to bsp who got "tons of homework" on the first day, poor things go join smtp lol advertise for smtp.
then early in the morning our principal announced to the whole school that the 90th anniversary gala dinner was a complete success. (i was not present cuz 1. i was not bothered 2. i didn buy the ticket which costs $35) then whole school cheered and i expect half of the school was expecting another half-day. then the principal was like "why are u all so happy for?", resulting in massive lolz. and then he said he hoped 100th anniversary gala dinner would be even better and told all of us to come back for the dinner. (btw he said got students from all the way from USA to come back for the gala dinner, omg didnt realise the students so enthu)(although many ppl said the gala dinner was a scam paid $35++ just to eat one quater of a duck. though not verified yet, but still erhem.)
then during lesson i was literally dreaming about nothing, cuz first day of school nearly all my soul has been sucked off by the anime i was watching, and of course by the appealing homework. so in the end only bio and maths started on new topic. bio was cuz got new teacher, then maths its duh. ihc not included cuz the whole class was making the teacher go off the point again and was talking about how she went to australia with my ex-form teacher and said after the working time in australia the only ppl who would work were everyone except for the locals. erps it *SO has link with singapore's economics.
then afternoon still need stay back to rehearse for the founders day prize presentation. its like...its only a walk up the stage, bow to the GOH, say "good morning sir", receive the prize, say "thank you sir", say "thank you" to the other person beside the GOH, walk to the center of the stage, bow, then walk behind the speaker and down the stage. ok although it LOOKS complicated but its actually dam easy, dun find the point ofr practising except as a reason to slack for a couple of hours.
prepare for tmr, which i expect will be a siege of homework coming by with feathered wings and sharp pointy tail, holding a trident in on one page and the future msg on the other. LOL descriptive phrases.
btw tmr need stay back to do projects day ppt, but then i got ep3, so still thinking of a good excuse to pon ep3. also thursday staying back to do experiment, so spam photos again.

school starting tmr. makes me so bushuang. my holidays is not at all enjoyable. AND its so short. a plus side is that i finally killed all my homeworks, unlike some HP peeps (got the info from zhen wei) who got a nice 60 page plus tutorial from slim this friday and had to finish an essay by tmr. poor things, btw its not MY fault if i went smtp and u went hp, who tell u go there to be tortured. (lol no offense)
now deciding to chiong ace before school got overbusy, and at the same time watching anime. everytime when i start watching anime i wouldnt stop till i finish the whole series. thats my weakness? lllolll

had our first experiment for our projects day. today is mainly get ready all the resources ready. at least i learnt how to use volumetric flask properly, while keith was like "i dun wanna die" when we dilute 98% sulfuric acid. chey, i dun really feel anything when i dilute the thing, except one drop dripped onto the newspapers below and there was an immediate black spot as all the moisture in the newspaper got absorbed by the acid until only carbon is left. cool...
basically today we prepared 2.0M sulfuric acid, 1.5M sodium hydroxide, iodine solution (actually is more of potassium-iodide-plus-iodine solution) and starch solution.
tmr (actually its today cuz its literally, 2am in the morning?) we will be carrying out the experiments about sulfur dioxide, more poisonous gases coming on the way...

*and of course there isnt anything happening tmr, im so not going to the school early in the morning for some not lame rehearsal. *furthermore i dont have anything in the afternoon so dun need to stay back to do projects day experiment. *and of course i so have finished all my homework so im so slacking now. *btw i also dun need to go for more experiments on thursday and friday and the days go so slowly i cant even feel wednesday coming by.
*and of course this whole post is so not sarcastic theres no astericks to show that im sarcastic (*)

these few days dam sian, esp when next week is school holiday. means a lot of homework and projects and ace must do.
yesterday and the day before yesterday was playing dota. my pro friend started to get noober and noober, and was practically feeding. come on la anti-mage fight luna and keeper of the light where got can get killed 6 plus times one. a medium person like me using puck only died twice lo. (partially cuz puck is too gay at avoiding dmg, esp keeper's illuminate and luna's ulti) at least in the end owned the oponent team. too bad i was still dead when the game ended otherwise would have some spectacular ending like using ulti on the frozen throne and activating shivas guard or something.
then the other game was yesterday, in which my cca member stubbornly played 3 v 5 insane ai. then the opponent as quoted from daniel, "dream team": dazzle, dark seer, jakiro, priestess of the moon and tiny. wtf la around 3 support and the other 2 semi-nukes how kill. its like dazzle got a heal, a slow, a 5 sec cannot die and an ulti that freakingly changes both sides' armour. then dark seer got a vacuum, a disgusting dmg per second ion shell that simply prevent my ally's poor melee hereos from ganking too much, a small time max move speed boost and an ulti that creates multiple illusions. then jakiro got 1 disable and 1 dmg+slow, plus plenty of creep control skills. potm got an escape/chase, one stun, one aoe nuke and an all-ally-invis-ulti. lastly tiny one stun, one aoe nuke, one dmg reduce and a freaking increase ur dmg passive skill. how am i suppposed to kill these heroes with an enchantress and barathum and juggernaut, esp when they stick together so much and both jakiro and dazzle got a mekansm.
ok kick aside the dota issues, tmr my project members coming my house do chem project, so expecting some fun and laughter and pissed off faces, esp when SOME ppl r so random sometimes.(excluding me)
now chionging my homework, got pissed with checking for meanings of some chinese phrases, esp when the net doesnt even bother to give u anything. so drop chinese homework and do bio first.

so basically today i went to the science centre TWICE, first time due to my sabbatical to see some stuff about maths, the second time to see other school's project at the science fair.
the main thing about the maths stuff is about optical illusion. although i've seen it for the n-th time but still look quite nice. was spamming "snap snap"s with my phone throughout.
then for the science fair we were randoming around with other classmates. then later ppl start giving out prizes so we were somewat like a paparazi wave following everyone around to see the judge giving prizes. then theres one project is about solar charges, then got a compound used is MoO3. then of course i would noe its molydebnum(VI) oxide, and of course daniel was somewat saying im wrong. so when i asked the presenter and he said its Mo(VI) oxide, u noe wat comes next.
NOOB DANIEL

yesterday's experiment follow-up
follow up on wat i posted yesterday. here is the result of the experiment:
In test-tube A with the dilute HCl:
the paper clip is only starting to react with the acid.
Observation:
effervescence is observed, a gas is produced.
1. The paper clip changed chemically due to the reaction between the paper clip and a gas.
2. Chlorine is cool
3. Im pro
In test-tube A with the dilute HCl:
the paper clip is only starting to react with the acid.
Observation:
effervescence is observed, a gas is produced.
In test-tube B with the dilute NaClO:
Nothing happened. in fact the paper clip became even cleaner...
Observation:
no observable change
In set-up C with the paper clip suspended above a mixture of HCl and NaClO:
firstly, the mixture changed from blue to green. and eww the paper clip literally rusted. theres a disgusting change in its appearance. imagine wat it can do to ur skin...
Observation:
the paper clip reacted with a gas produced between the reaction of HCl and NaClO to form a new substance (partially). the gas produced is able to dissolve/react with the mixture to form a green mixture.
Now comparing the 3 paper clips in the 3 set-ups:
1. The paper clip changed chemically due to the reaction between the paper clip and a gas.
2. Chlorine is cool
3. Im pro

random experimentation
this week sabbatical week, means no official lesson for one week. so today i conducted a lame experiment at home:
hypothesis: a substance given out when HCl and NaClO reacts causes paper clip to rust.
items needed:
dilute HCl,
dilute NaClO
metal paper clips
test-tubes
plastic container
Steps taken:
1. Pour some dilute HCl into a test-tube, put one paper clip into the test-tube.
2. Pour some dilute NaClO into a test-tube, put one paper clip into the test-tube.
3. Pour both dilute HCl and NaClO into a plastic container, dangle the third paper clip above the mixture and cover the set-up.
4. Wait till the next day to see the results.
Equation involved:
2HCl (aq) + NaClO (aq) = NaCl (aq) + H2O (l) + Cl2 (g)
Possible mistakes:
1. Both HCl and NaClO are not pure, they actually came from two different toilet cleaners, thus the experiment may not be accurate as there may be other substances in the toilet cleaners that may react with the paper clip and with each other to produce other gases apart from chlorine.
now all we have to do is to wait for tomorrow for the result...

1. Pour some dilute HCl into a test-tube, put one paper clip into the test-tube.
2. Pour some dilute NaClO into a test-tube, put one paper clip into the test-tube.
3. Pour both dilute HCl and NaClO into a plastic container, dangle the third paper clip above the mixture and cover the set-up.
4. Wait till the next day to see the results.Equation involved:
2HCl (aq) + NaClO (aq) = NaCl (aq) + H2O (l) + Cl2 (g)
Possible mistakes:
1. Both HCl and NaClO are not pure, they actually came from two different toilet cleaners, thus the experiment may not be accurate as there may be other substances in the toilet cleaners that may react with the paper clip and with each other to produce other gases apart from chlorine.
now all we have to do is to wait for tomorrow for the result...

3 cheers for myself who finally posted something after 3 days of hibernation. nearly the end of the term, next week is sabbatical week, which means we choose a program to attend. the main point of the program we r choosing is to either get ACE points or slack for a week.
throughout friday and saturday i was on a dota spree, except for saturday where i spent half of the day sleeping, one quater of it doing homework and the rest 2 hs spamming through.
now doing my english expository writing which is due tmr, so sad. was just looking thru the topic of capital punishment when i got sick with all the methods.

then its second things second.
im trying to think of something to write for today:since english test was way over so todays english lesson was quite relaxing. onli need do a small reflection thing and the rest of the time was watching films.then stayed back after school to do my physics module project. it was about using soalr panels to charge up batteries. then completed the experiemnt in like 10 minutes cuz the sunlight was very bright and also the charging was very fast. now all need to do is to prepare for tmr's presentation.
below is some part of the video of the experiment:

below is some part of the video of the experiment:
the first one is to show that the solar panel does produce electricity by using the device to measure the voltage.
then this one is to show the voltage left in the battery. i have to actually use the battery for some purposes on the spot. (ok i used to charge my phone lol)
this one just let u see the whole set-up, and to show that the sun is indeed bright...
this last video (featuring me and my trademark black jacket) is to show u the voltage of the battery after we have left it in the sun to charge for around 5 minutes. notice the significant increase in voltage compared to the 2nd video. also the voltage in the battery in this video has been fully charged. so overall success =)
first things first, LAST friday we had chem practical again and this time was about identification of gases: hydrogen, oxygen, sulfur dioxide and chlorine.
this is blatantly chlorine gas. as u can see the yellowish-green gas within the test tube. and it bleaches both litmus paper at the mouth of the test tube.
this one is supposedly using CuSO4 to catalyse the reaction between Zn and HCl. but then somehow the CuSO4 got reduced to Cu. must ask the teacher about it.
this is me testing for oxygen. see how it rekindles the glowing splint.

for yesterday
Mainly this is what happened yesterday:
We had our IHC test during the second period. Then the relieve teacher came in 7 minutes late. wtf. Then looked at the questions, the first question is quite simple but still dun understand the second question much. wtf. So spent all the time chionging through the first question which is worth 12 marks, then realised the teacher is not giving any extra time even after he was late. wtf. was still trying to weigh the three points i wrote when the relieve teacher said pens down. wtf. so in the end only half managed to weigh the questions so wont be getting my L5/11-12 AND i never touched the second question at all. wtf.
so after the test about the whole class was screaming about how they dun have enough time to finish the second question so some suggested asking the IHC teacher to moderate the results.
Then goinging back to what happened today:
My IHC teacher finished marking the paper at blazing speed and thus returned back our paper today. wow. realised to my surprise and (?)happiness that i got a 10 out of 20, happy because i never fail and can actually get a 10/12 for my question 1. if im in sec 2 i would usually get a 4-6. then the whole class was asking the teacher to moderate marks then she looked as though she's considering. only looked as though. but even if moderate its only 1 mark i think, and 1 mark has no big difference on my end result only 2 marks make a difference, since my CSC and IHC results when added together and give the average its exactly 65/100. if 1 mark is added the end product is only 67.5, which is still a B3. but 2 more marks will result in a 70/100, which is a A2, so hope will moderate 2 marks or dun moderate at all. since im such a selfish guy i would rather let others dun hav that 1 mark then letting me hav it, since the 1 mark dun make a big difference.
