Out of sheer boredom..i decided to....

...share the joy with all of u.

Happy Lunar New Year & good health to all. :)

Weird stuff

Just visited another blog that's pretty hot within the M'sian blogging circle and I found this.

No idea what it means, probably means nothing but well photoshop skills, I can appreciate.

I ate salmon sashimi today for the first time and, strangely, it felt just like any other cooked food except for the slightly sticky texture. I have no idea how is it supposed to taste nice when all I can taste is the soy sauce and wasabe. Duh!

Back to QM2 tutorial. Yay! row x column = column x row? column x row = column dot row? Ahhhh! I don't like vectors. But its still better than nuclear physics. :(

The best of investigative journalism

This might be a little late but its two thumbs up from me!

Read more here

Basically its about debunking myths such as detoxifying your body through your feet!

Wah!!!

A lot of chio bu!!!

The one where I puked..

Nb, just kind of recovered from Friday drinking session with the guys. Totally wasted man, never felt so giddy before! All thanks to silly Jeff, it was a mistake to let him be the 'shit king'. Looking at him pour the tequila for everyone, was enough to puke already hahaa!

Die already lah, now that I have successfully poisoned Ahjing, Nick, JS and a number of others with the DotA virus, hopefully I will not neglect my schoolwork. Especially now that QMII is here to haunt all of us. I mean with Prof. Englert, the first lecture is a preview of many things to come.. sigh. 1 hour 45 minutes with no break, and with tremendously mind-boggling stuff to understand.

And what's with Prof. Thomas Ospo*something*-wicz? He looks like the guy from Sellavision! You know you know? The host who introduced Didi 7, Astonish and I think Duralube and some other car polish & wax. I think its his glasses anyway.

Ok lah just a short post to keep this blog alive, really lazy to do things nowadays.. perhaps its the rainy weather, lack of physical exercise retards the brain. Oh and tequila too! =p

Woo!

Yay exams WERE over, haha! Been lazy to blog until now. Well its weird that after exams I have been feeling really strange. I can't seem to catch a lot of sleep!

Normally I would sleep earliest around 2am, now? 11pm already start feeling groggy and drowsy and the best part is... I wake up at like 5:49. Wah lau like those 老人lor! Sleep very little then maybe early morning wake up and sweep the floor or go outside to the neighbourhood central to buy breakfast back home. Most probably it would be 斋米粉! Hahaha!

Now can start to feel for KC when she insomnia but why my insomnia come in the holidays one? I don't mind waking up earlier but not so early lah! WTF I wake up before the birds start crowing and beeping and cheep-ing.. Ok they just started.

Today I went to Msia and took the yellow bus from JE. As the guys wanted to go to Larkin, we saw that the bus route went there, asked the price for the ticket then we bought it. KNN WTF, that's the biggest 贼船 I have ever sit in lor! NB!!!!! The bus went by Tuas 2nd link then went to GP bus terminal. Its almost at Tian Lye restaurant liao (black pepper crabs anyone?).

After that, we have to change a bus. The bus number was 666. How ominous right? Enz called it the Devil's bus.. right... and did I remember we were boarding it? From GP, it didn't turn right into the long stretch that goes back to the NSHW, omg it went from the super duper ulu 'mount akina' type of roads. Then the driver also like ferrying tofu, Initial D style driver. The body roll on the bus was atrocious man! Then Liu Jing was eyeing me in a worried way which was kind of funny... hahaha! Like, are we going to die here in a devil's bus in the middle of nowhere?

From Jurong East to Larkin bus terminal, it took us approximately 2 hours journey. Jesus... really a bit pain in the ass after we alighted. We were thinking (ok la rather only I was thinking) maybe the locals would laugh like siao after seeing Singaporeans come to Larkin on Devil's bus. Somehow this created the loudest laughter registered for the whole day :p

I also realised that Holiday plaza is a vice city. Hahaa no la but well they do sell many games, dvds and cds at 'discounted rates'. Lol, yeah so basically the main aim of the trip was to go Larkin check out the price of the coach to Genting, and to stock up on movies and games. By then it was already 8+ so we just went to the Big horse garden to eat our dinner. Is it called Taman Sentosa? Not too sure.. maybe JK or $9.90 will know better.

Aiyah wanted to blog more but the Sun is rising liao.. Duh.

Its the exam season again

Oh yeah it means more of mugging and mugging, how boring can that be?
Revision is going on smoothly but slowly for biophysics, partly because Janaky's monotonous voice is echoing in my head.

Sometimes I just feel damned stupid, can't study faster and just absorb every shit thing then go to exams and do a decent grade. Or am I just lazy?

I am so bloody frustrated

Quick break!

The weekend has passed in a flash! :(
Well the exams are drawing near anyway so its about high time to start mugging. Its also been weeks since I listened to Mr Brown's podcast on how to zhng your car and we're still laughing about it. So here's a few useless facts about the podcast and its contents~

1. The turbo sound that Mr Brown mentioned really does exist. I've personally witnessed the sound on a souped up Honda Civic before. Most hilarious in my opinion :p



2. The stickers that are meant for cars are all waterproof. For obvious reasons.

3. The blue neon undercarriage lights are illegal not standard.

4. Same goes for aftermarket retrofitted HID high intensity discharge jinon (Xenon) headlamps. Currently a host of cars from cars have them fitted as a stock option so they are allowed. Toyota Camry (facelifed version), Honda Odyssey(facelifted version), Mazda RX8 are some of the examples. Without proper alignment, HID can be very glaring to other road users. Faulty installation of the ballast may also result in a fire hazard.

5. Spoilers are not supposed to protrude from the car body. More info @ onemotoring.com.sg

6. Honda vehicles in general have a higher insurance premium compared to other Japanese makes in the same class. This is believed to be caused by Honda's bad reputation among insurance firms as a boyracer's car.

7. The loudest exhaust I've ever heard came from a Lamborghini Murcielago/Gallardo along East Coast Road (Katong). It was cruising at less than 60kmph I estimate. The 2nd loudest came from a bike's pipe. The sheer volume triggered 3 car alarms as the bike went past. Bloody fucker zhng so loud for fuck.

8. Lowering springs are available for lowering the car. Lowering the car brings benefits such as better aerodynamics (Ground effect) as well as higher stability due to the lower centre of mass!

9. DOHC stands for dual overhead camshafts. The camshafts are mounted on top of the cylinders and there are separate camshafts for inlet and exhaust vaults.

10. Changing an exhaust to a larger one (in diameter) does not necessarily mean better power. Most probably the low end of the engine's range will lose some power and gain some power at the high end.

Oh well enough of my boliao-ness. But ...

Mr Brown never include the following:

1. Add the dark dark ah beng tinted film.
2. Mugen sunshade sticker.
3. Change steering wheel to Momo 3-spoke steering.
4. Wide bodykit.
5. Huge sports rims. Preferably CHROME.

HAHAHAA!!

My personal opinion on zhng-ing your car. By all means do go and personalise your car but just keep it civil and don't zhng your exhaust until it wakes up the whole neighbourhood. Its plain fucking stupid and inconsiderate. Might attract angry drawings on your car paint anytime.

Zhng your car with HID, jolly well make sure your HID doesn't blind other road users. As for Mitsubishi Grandis' rear LED lights, I'm sorry jkaiser but it comes stock leh =/

Look fierce can, don't drive fierce except on the track.

It all goes up in smoke

PC Lee's seems to have won the battle against smoking, apparently he has been abstaining from cigarettes for quite a few weeks already so I thought most of the army guys would know and try to egg him on. (Not egg him on to pick it up again ok!)

However he has had new issues so all the best to you brother!

Recently also watched on TV that 李铭顺and er forget it my Mandarin sucks. Quan Yi Feng and Huang Hui are pledging to quit smoking. No doubt some part of government awareness campaign. Well but I do applaud their first step in coming forward to try, especially Quan Yi Feng. Evidently her daughter is emulating her smoking at home, and she said she felt guilty and that she didn't want this bad smoking habit to pass down to her daughter.

Been reading a few posts from a fellow Phy major and feel that althought we don't really click/clique, I kind of share the same sentiments with him. That both of us don't really excel at studies, like spending power and being in control. Talk about finding a 知己 in the most unlikely places.

Of KFC and silly blunders

One fine day, my younger sis developed a craving for KFC. So we browsed through the discount coupons very happily and chose our meal.

Then we drove to BP plaza and I parked the car at the carpark opposite the shopping centre. As we were walking towards BreadTalk, Pei suddenly asked me 'kor where's the coupon?'

I went limp in the knees cos I thought she brought it. Dammit, We came without the fiaking coupons. Nb... so I ended up buying PIAC (Pasta in a cup) and she bought something else, oh I remember now. She bought the 4 piece devil drumlets from KFC. So we were both quite pissed at ourselves for being so damned forgetful while trotting out of the shopping centre when... WTF! The guy from KFC is giving out the discount coupons! KNN! Asshole why wasn't he there when we walk in. Damned suay man!

After cursing and contemplating whether to knock the daylights out of that bugger we reached the car and... lo and behold...

THE COUPON IS ON PEI's SEAT!

YYYAAAARRRGHHHHHH!!!!~~!!!

20/20 Vision...

What is 20/20 Vision?
=====================

Visual acuity is typically measured with the use of a standard eye chart called the Snellen chart. It was devised by Dr. Hermann Snellen, a Dutch Ophthalmologist, in 1862. It was originally used at a standard distance of 6 meters, which is about...

Read more about it here
Scroll down until you see the Snellen chart. Yes, the one that you have to look at when your health booklet has to be checked in primary school.

Well at least its stuff that I never knew. "Godma" gave us this site for circular aperture diffraction stuff but well as you surf there are always interesting things that you find out!

:) (why am I smiling when I owe my godma 4 lab reports and a 45 minutes VIVA? ccb...)

Insomnia?

Am I suffering from insomnia? I told JK I was going off at 1:30. Until now still unable to sleep, damn it!
At this rate I won't be awake in time for solid state physics. Freakkkk!!

Gah! Gdnite all.. my neighbour's rooster is gonna start crowing in 1 hour's time.

Lingering thoughts

Been thinking quite often these days, one is about a letter to one of the local paper's forums. Actually it came out from Jingkai's mouth lah but anyway this person was suggesting a death sentence for hit and run criminals. Most probably the idea came to him for the recent case of a taxi hitting someone or some vehicle and didn't stop.

As I watched the news where the one of the local vehicle repair workshops got a plaque from the SPF for being an alert and vigilant citizen blah blah .. it just came to my mind, what would I have done if I hit someone and there's no one around and the person I just hit is confirmed dead. It would be a farking dilemma wouldn't it? I would surely be in one, now does that spell any troubling traits about me I wonder. As Jingkai told me he would surely stop since he didn't want to be forever haunted by this incident, I also searched my mind for a piece on conscience.

What if you surrendered and admitted to running that person over? If this law is passed then you'd better be prepared for a noose around your neck. Well that just means game over right?

However if you ran, well you would probably end up hiding for the rest of your life, probably in any country if you can really get out in the first place. And being haunted by that incident forever. I don't know which is better but both options aren't that good in the first place.

I also realised that my studying pace is so freaking slow compared to my peers. Most of the time JK can finish revision way ahead of me while Zeff can really chiong last minute and yet know his stuff much better than me. So now really quite worried about this, I mean this isn't just about acadaemia but part of a life-long process. Learning self improvement is very important and I also realised I have quite a lot of other flaws. That day while I was revising M&C I realised there was a mistake in one of either JK or KC's drawings/workings/explanation. Though I knew it, I just didn't open my mouth to spit it out. Weird right?

So after a day of thinking the next day I forcefully made myself explain how a circuit worked to KC. Hur hur.. that was really silly and yet enlightening. Machiam doing a mini presentation.

So much for weird traits about me. Have you searched your soul today?

Photos!

Section analysis of a standard 10 micron grid. You can see clearly the recesses every 10 microns.
A 3D image derived from contact mode AFM. This means that the tip and sample are actually "touching" each other.
Power spectral density image of contact gold. This time I'm using a picture derived from the phase difference between some signals. (I also blur) Don't ask me what is PSD, it just gives a lot of information.
A flattened image of the standard grid. Look at the phase picture on the right. It provides fricking accurate pictures of the surface characteristics. In this case, you can see the roughness on the surface.

Nothing to blog about :/

Recently really tired and busy. More busy than tired actually but well I'm fighting the good fight. Been downloading some songs from The Carpenters and they really have soothing songs that never fail to make me... drowsy? SHIT..

Anyway I'll upload pictured from AFM soon. Just to make you people even more bored. Hur hur hur~~

1 lab report/viva and biophysics test to go!

Faraday's effect explained..

Warning: The below entry is full of technical and weird physical nomenclature so if you find Physics a turn off please look away from your monitor screen. LOL~

What is Faraday's effect?

One observes that when a plane polarised light passes through a magnetized medium (eg: a glass cylinder subjected to a B-field), the plane of polarization is rotated and this is known as the Faraday effect. Michael Faraday discovered this in 1845 and this is one of his more 'unknown' discoveries relative to the discovery of the transformer.

Basically we start off with a 50W halogen lamp and then a the light beam passes through a filter, hereby filtering out all but a particular wavelength of light. This filtered light goes through the first polariser, set at 90 degrees before passing through the glass cylinder. Note that the glass cylinder is placed in between 2 poles of an electromagnet such that direction of the B-field is parallel to direction of irradiation. The light then passes through a 2nd polariser (analyser) before a focusing lens is used to focus the image of the cylinder's image onto a translucent screen.

Procedure: Since polariser is set at 90 degrees, we would expect extinction to be at 0 degrees. However the plane of polarisation would be rotated by the B-field and hence we would expect some non-zero value of delta phi. We do this by adjusting the analyser to find the point of maximum extinction.

The B-field values were also varied by controlling the DC current supplying power to the electromagnet, and we find that the greater the current the greater the Faraday's angle. So delta phi is proportional to B.

I won't go into detail about the Verdet's constant, because its just mathematical stuff. Lazy me wahaha!

Why does this effect occur? This is pretty interesting stuff at least to me. What do we mean by plane polarised light? We are essentially talking about the direction of electric field when we say plane polarised light. Plane polarised light can be visualised as LCP and RCP light. LCP = left circularly polarised and RCP = right """

We can consider it like this because if we consider light to be circularly polarised, the 2 circular vectors always have a resultant which is along the plane of polarisation. For normal materials, the refractive index varies proportionally with wavelength (the lower the wavelength, the higher the index of refraction)

For most materials, there is a UV resonance frequency or associated wavelength, such that peak resonance is reached when this particular wavelength of light passes through. Refractive index is a maximum at these points. When these materials are subjected to a B-field parallel to direction of irradiation, something occurs and its known as the Zeeman effect. Nabeh, I also dulan at this point.

What Zeeman effect does is, it shifts the point of resonance in different directions for LCP and RCP. So what sense does it make? Ok imagine LCP and RCP passing through the medium but LCP experiences a lower index of refraction while RCP experiences a higher index of refraction. When they recombine again after travelling through the medium, add up the 2 vectors and you get a new plane of polarisation. Cool..

So this BRIEFLY explains what the Faraday effect is about. Hope whoever is reading this understands. If don't understand, don't find me wahaha! Kidding. :)

Faraday's effect

Made me so damned tired, everyday have to type report and research dunno what Zeeman effect. Jesus, enough of electron orbitals and energy gaps!

Just finished typing my report, it sounds damned intellectual when its not and it even talks about pupil dilation as an error source. Haha, Beng should know about that!

Basically this semester seems to be quite packed for me, haven't had dinner at home for a long time already! But strangely, I haven't really been missing it. I really hope this momentum can be carried on (conservation of general momentum) hur hur...

Its a wrap!

Argh..

Basically the last week (this was supposed to be a National Day blog), I've been working as a general helper for the Singapore open shooting championships. So much stuff to blog about.. don't even know where to start..

The wiry issue..

We worked at score-takers at the shotgun range and for the skeet event, the referee will have to walk around with a hand-held wired remote that activates the skeet 'house' to shoot out a clay pigeon. So the problem came when the referee has to walk all around the range and the wire would get tangled up IF the referee zig-zagged in between the range's pillars.

Well in my opinion, this type of thing is really very simple, just that I kept quiet but JK did not so he politely suggested to the referee that perhaps he might want to stick with walking in front or behind the pillars, but not both at the same time. Which kind of got us into a "pep talk" from TP, the overall IC (OIC) for the general helpers.

As we both agreed, its a waste that people like TP don't sign on in the army because he's so bleddy kanchiong spider.

TP: "No matter what, he's still the referee and because he's a nice guy, that's why he didn't say anything. If its other refs, he sure 'kan' you upside down."

How stupid can you get man, this type of thing is called initiative and JK tried to convince him that suggesting this to the referee would only make everyone's life easier but he 'eh xi' refuse to listen to us. Duh! Stuff like we are here as general helpers and we're being paid to help etc etc.. really dumb shit in my opinion.

Even if kena fuck by ref, I always have the option to just go home lor.. like this is a permanent job.. anyway JK made a good point about the job being a short 6 days assignment and it wouldn't be worth making an enemy over this type of crap. Couldn't agree more about that!

Oh btw, happy belated birthday Buddy (I wished you already though :p)
