Soaps, Detergents

1. Whats a soap? In chemistry terms, a soap is a sodium or potassium salt of a fatty acid.

2. Basic formula for soap; RCOONa (for sodium soap) or RCOOK (for potassium soap). The R stands for the alkyl groups of carbon chain.

3. How to make soap? Saponification (Sa.po.nee.fee.kay.syen).

4. Ester + alkali = soap + glycerol.

5. Contoh: stearate(ester) + sodium hydroxide(alkali) = sodium stearate(soap) + glycerol.

6. Some names of soap: sodium stearate, sodium palmitate.

Mercedes SLS; The Gullwing

At first I thought it was ugly. But, as time goes on, it started to look decent. Now, I can't take my eyes of of it. It's my new desktop wallpaper. When you say something grows on you, it refers to a situation wherein the first impressions didn't even catch your attention, but, as time passes, you take more notice of the thing, and you cannot help but appreciate what you missed in the beginning. Like, for example, you think a car looked like a dead frog when you first saw it, but eventually, you start liking the car, for reasons 'unexplainable'.

This car grew on me.

I don't know where to point. Maybe it's the doors, or the sharp grille. Probably the retro 50s design cues of the benz sl300. But definitely, the overall shape is brilliant.

The engine...hell big. 6.3 litres churning out 571 horses. I'm not really a horses counter. I believe perfection lies in the overall package of the car. But horses do help. Big engine plus lightweight plus grip plus unique styling equals Mercedes SLS AMG. The end.

Man, Jalil, I really don't get why you despise the looks of the SLS, you anti-Mercedes, BMW biased *******:P

Anyways, click the link http://www.autoblog.com/2009/09/11/everything-you-wanted-to-know-about-the-mercedes-sls-amg/ to read a little more about the SLS AMG and view the picture gallery.

Transformers (Physics Punya)

1. A transformer is an electrical device that increases or decreases an alternating voltage based on the principal of electromagnetic induction.

2. Electromagnetic induction pulak, is the production of an electromagnetic force in a conductor when there is relative motion of the conductor across a magnetic field.

3. EI ni ialah penghasilan daya (force) elektromagnet apabila konduktor bergerak dalam medan magnet.

4. Kita ada step up transformer dgn step down transformer.

5. Senang saja. Nak tau kata dia step up transformer, primary coil dia sikit, secondary coil banyak.

6. Nak tau kata dia step down transformer, primary coil banyak, secondary coil sikit.

7. The term 'ideal transformer' refers to a transformer that has equal output power and input power.

8. Efficiency of a transformer; (output power/input power)x100%.

9. Output power=secondary volt x secondary current. Input power=primary volt x primary current.

10. There are 4 main causes of heat loss in transformers. a)Resistance of copper wire. b)Eddy currents. c)Magnetization and demagnetization of core. d)Flux leakage. (FREM)

11. How to counter flux leakage? by winding primary and secondary coils closer to each other.

12. How to counter resistance of wire? by using thicker copper wire to reduce resistance, or by using cooling fins (sirip penyejuk) or coolants to reduce temperature of transformer.

13. How to counter eddy currents? by using a core made from thin plates of soft iron insulated from each other.

14. Lastly, how to counter magnetization and demagnetization? by using soft iron core which magnetizes and de* easily.

*What exactly is an eddy current? I honestly don't know. Someone good at explaining things please explain this term to me. Thank you.

Praise be to God, the Exams Are Over!

Shout for joy!!!

1. Alhamdulillah. Syukur ke hadirat Allah. At 2.oo noon today, Thursday of 28th of May, the mid-year examinations are behind us all. The last paper done was Physics.

2. Tears and cries of joy surrounded the class. There were also some laughter in the background.

3. Peers were seen hugging each other, releasing the joy in their hearts. A mid-year exam well done, I suppose.

4. Thanks be to all teachers, and classmates, for making this exam one hell of a wake-up call for the majority of us.

5. Why do I say this? Well, the tests were quite hard, very very time-consuming, and boring. This is a very realistic simulation of what the actual SPM come November will be like, I guess.

6. Some subjects, turned out ok, great even, while others (I don't want to say here, errrm*add maths*), well, lets just say there's HUGE room for improvement for most of us.

7. And finally, with a guy in my class singing Sudirman's Merdeka song, we are all free from the horror and insanity of two weeks of mid-year exams.

8. I just hate formal exams. I mean you go to school, for 8 hours, doing exams. For two straight weeks. Two straight weeks of brain-melting exams. Two straight weeks of not learning anything new.

9. The reality just makes me sick. Just some of the flaws in the modern education system.


10. Just forget about what you just read. I was only reflecting upon my life. Be on the bright side of things.

11. The Axiom wishes all a good two weeks of rest. Stay healthy. Assalamualaikum.

The Student

1. Right. Ok. Now let's explore the inner workings of my friend, Amzar's mind, through his piece of sketch, done today in class, during Bahasa Melayu period.

2. I asked Amzar to lend me his BM exercise book, to scan his artwork. He agreed. So here it is.



3. It's a drawing of a guy. A student, I think. Who was on his mind when he drew this, god knows. I wonder... I leave that to your judging. It looks like he's wearing standard school uniform, has terrifyingly long hair, and his face creeps me out.

4. What's cool about Amzar's drawing of the student is that it was drawn directly after copying the teacher's notes (syair) on the white board. As said, this piece of art was scanned directly from his exercise book. I tell you, this guy can get really inspired, at the most unexpected times.

5. I love random art. This is an example of random art done by my classmate. Totally random and inspired. Oh, Hanif also added some details on the guy's pants. Thanks...

6. You can tell what someone is thinking about at a point in time through random art. That's the cool thing about random art.

7. Thanks, Amzar. Thanks for sharing. Really appreciate it. Good night people. Assalamualaikum.

2 Swords and a Spear

1. It was Biology class. Biology class after recess.

2. The teacher was talking in front. Talking. Talking about biology. Giving out the answer to the worksheets. The worksheets she had given. Everything we need to know about the workings of the nervous system.

3. Along the lesson, she kept telling us, repeating about how difficult biology is, all the things that need remembering, the commitment needed in constant reading...

4. You can tell it was a boring lesson. It was obviously a boring lesson. But I enjoyed it anyway. I get fascinated easily by the most boring things.

5. But my friend Jalil, started showing signs of boredom. He started drawing swords in my notebook. They looked cool. I like looking at sketches of cool, long swords. As I said, I get impressed easily.

6. He also drew this kinda african-tribal-looking spear, which had some sort of fin-like extensions on both sides.

7. There was also this two-bladed dagger thing, which also looked cool.

8. I am collecting artwork, and his sketches were rather inspiring. These artworks from Jalil reveals his inner-subconscious mind, and shows the inner-workings of his brain at the time of the biology lesson.

9. So, I asked his permission to put the drawings on this blog. He agreed. So here they are. Thanks, Jalil. Totally appreciate it.

Lukisan Petang

1. Hmmm. Right. OK. First thing, apologies. I've been off my blogging duty for 1 whole month. I am sorry for the long leave. It's just that, owwhh, you know, school, homework, exam, stuff...I'm sure you understand. Again, my sincerest of 'sorry's.

2. I've got a masterpiece to share with all of you. It's a one-and-only original artwork by my well-known-friend, Hafizan Halim. He showed it to me during extra-class period today (physics). The realism of this piece of drawing is astounding. I know that, to art people, who posess the god-given skills of sketching and rendering, or have learned it somehow in some point of their lives, that this is just 'ordinary, anyone can do it' stuff,... but to me, this, this is beautiful. I mean, the detail, the realism... man, this is great stuff. This is one good sketch.

3. According to Hafizan, he drew it yesterday evening, spent about 30 minutes doing this, using his Mitsubishi technical pen, while at Hafidz, a close friend's house. So, this piece is called 'Lukisan Petang Ahad di Rumah Hafidz', by Hafizan.

4. It's a view of Kolej, the row of classes near the green, stagnant 'kolam', you know... let me relate this. In 2008, the furthest class you see in the drawing used to be 4 Omega.

5. So, thank you, Hafizan, for the sketch, and thank you for letting me share your art with all of us in my blog. And with this, I hope I can post more artwork on this blog in the future. Anybody wanna share? I'm at 5 Omega. Just go see me sometime if you have anything good to be shared and recognized.

6. Good night people. Stay healthy. Assalamualaikum.
