Post-Exam-Stress-Disorder Thursday, Nov 29 2007 

The first thing I did on my computer after the finals (and after wasting money and time at zouk), was to waste another 2 hours of my life away, making a midi of my current favourite jay chou song.

This is the first time I made a midi using my new computer with a lousy Sigmatel sound card with limited midi bandwidth. From now on, have to make some compromises because apparently my computer cannot play more than like 10 instruments at the same time – it will just cause notes to simply “disappear”. I also realised midis sound differently at different computers. This actually kinda sucks….

Sigh. Oh yea, fluid mechanics paper was a disaster (though the other 3 papers weren’t good either.) Everyone I asked had his or her own different answers. So basically, everyone died. And it’s ironic that I am least afraid of the hardest module, and also the module which I studied the least, simply because everyone else is screwed with me. Haha!

And sad to say, that is not the last we will get to see fluids. von Karman integral will make a bigger appearance in heat and mass transfer, one of our modules next semester. No good riddance for him ARGH.

On good music Tuesday, Nov 27 2007 

Always had great appreciation for Harry Gregson Williams / Joe Hisaishi’s instrumentals, and just heard pieces by an extremely talented composer and pianist who redefined my benchmark of excellence.

Unfortunately he is no longer with us. RIP; your short life was indeed well-lived.

Science v Engineering Tuesday, Nov 27 2007 

Science

* You understand everything until the exam

* You forget everything immediately after the exam

Engineering

* You are totally clueless until the exam

* You suddenly understand everything immediately after the exam

1 paper left.

Freaky Dancer. Friday, Nov 23 2007

Do you think she is moving clockwise or anticlockwise? Bah all you maths and science whizzes will surely say anticlockwise. But believe it or not some of us see her as moving clockwise. I was insisting that there is NO WAY SHE CAN MOVE ANTICLOCKWISE. Until I stared at the bottom left part instead of focusing on her.. then BAM! she turned anticlockwise!!! After some practice, I could get to staring at her directly moving anticlockwise, although after a 1 sec-long blink she got back to moving clockwise again. I think it has something to do with her whole body being black, so it is not certain whether she is standing on her left leg or right It’s true! one moment she is turning her left leg and the next moment she is turning her right. This is some cool but freaky shit!!!

Ok.. I should REALLY study.

I'm Right-Brained. WHY?!?!?! Friday, Nov 23 2007 

Despite having 2 papers tomorrow, I decided not to study and surf facebook instead. After throwing chickens and trouts to my friend Shiqing I took a brain test.. and …. get this..

I”M RIGHT-BRAINED?!

After researching on the characteristics of a right-brainer, I conclude that the test is accurate. I quote from some websites…

Right brains are honored in eastern cultures more than western. They are seen as less smart because of the manner in which they process information. Rights don’t go from Point A to Point B. Right brains don’t like to listen to directions and don’t like to read them. They scan quickly and figure out what to do without reading details. Reading directions carefully is a detailed activity for the left-brain.

Oh yea, I’m bad with directions.

On a spelling test, a right brain hears the word “dog.” Their mind wanders to the thought of the neighbor’s dog which barked most of the night, that reminds them of the fact that the neighbors are in the Bahamas, which takes them to an island with palm trees and sandy beaches, which reminds them that they need a bathing suit for this weekend, which reminds them that they will need to take spending money… Teacher says, “Word #7 is house.” Student raises hand and asks what word #6 was. They’ve checked out for a while.

I can’t pay attention in lectures for this reason!

Right brains don’t explain what they feel well and are misunderstood. They think of one thing, say another because their brain has already moved on to another thought. Unfortunately, their mouth is still moving.

I do speak without thinking carefully first. And after which realised I just said something damn stupid and wrong and had sharper people giving me an anticipated rebuttal.

Right brains are non-judgmental and often have no opinion on many topics. They can see both sides and are often seen as wishy washy or lacking values. They see the whole person and are less likely to condemn a person because of a flaw. They often have an interesting group of friends.

Hmm..

Rights select careers as:

  • entrepreneurs,
  • athletes,
  • sales,
  • artists,
  • musician,
  • craftsmen,
  • dancers.

Ok now.. WHY AM I STUDYING ENGINEERING?

And having huge difficulties following lectures. For this reason:

The right brain however, processes from whole to parts, holistically. It starts with the answer. It sees the big picture first, not the details. If you are right-brained, you may have difficulty following a lecture unless you are given the big picture first. That is why it is absolutely necessary for a right-brained person to read an assigned chapter or background information before a lecture or to survey a chapter before reading. If an instructor doesn’t consistently give an overview before he or she begins a lecture, you may need to ask at the end of class what the next lecture will be and how you can prepare for it.

It’s true; I have to painstakingly go through a chapter on turbulence and viscosity several times, before I see a light, like OH that’s what they’re finding. No wonder they place that equation there! And before I feel some confidence in the subject. Most of the time I just don’t.

Sigh… okok back to study. I’m not confident with this semester actually…

Who the heck came up with this tagline?! I even saw it on tv too. In any case, it sure made my day today HAHAHAHAHAHA.

Honesty. Wednesday, Nov 7 2007 

So today’s the last day of LSM2201 open lab. After spending several weeks in the lab, (wednesday and thursdays, 0900 to 1830 to be precise), chopping up and purifying rat liver, I think I will actually miss the lab when it’s gone. We took some pics for remembrance. Despite our utterly terrible results, we had some good times.

The closure of the lab will mean we have to start our final report. I have already written the “first draft”, and one can see how pathetic our results are. Ok it’s not as bad as what I wrote, but quite close to it. We screw up because of silly mistakes (many committed by me) which ruin an otherwise perfect set of data.

Now comes the temptation to cheat. I can choose to ‘magic’ the data until it fits our hypothesis, and get high marks, or choose to be honest about it and then trying to figure out how to account for it. Honestly, under normal circumstances, I would have chosen the first one.

But, I don’t know whether I’m lucky or unlucky, I have been teamed up with a group of very righteous mates. All refuse to fake data or cheat, not because we may get found out, but because it’s wrong. I was the opposite. I kept giving them ideas to manipulate data. Even when we were heading home just now, I was still trying to get them to fake the results. They silently nodded their head and went “yea, ok… I guess if there’s no other choice”. But when I asked them if that’s ok, they quietly revealed that they weren’t very comfortable with this actually.

The more I think about it, the more I feel bad. One can always say this is a harmless experiment, so it’s ok to cheat. One can always say scientists have been cheating all along. But I guess it always become a habit, and for sure “no lie is of the truth“, and also, even if everyone is cheating that doesn’t make it a right thing. Even though it may be harmless now. Right? (lol trying to convince myself here.)

To make the temptation worse, almost all my friends are like me (advocate cheating), and their teams are also like me. So I should not expect bad data from any of them (then again, their data is not bad to begin with).

I can’t even bring myself to tell my friends that I am not going to cheat, for fear of hearing the brutal news: “wah really? very hard to account leh.” “you know your this mistake is quite a serious one? you’ll be penalized heavily.” So I think I will just shut up, unless they ask me.

As of now, I decide to be honest, more because I respect my teammates decision, and I respect their integrity, than anything else. If not for them, I will confirm take the easy way out and liquid the anomalies away. That is why it may be a good thing that I am teamed up with them. And in any case, if I screw up, I can always.. S/U.
:)

But hopefully, in the near future, I will choose to be honest because it is the right thing to do.

The Wonders of Beer. Saturday, Nov 3 2007 

1) Beer makes you happy.

2) Beer reduces risk of heart disease.

3) Beer makes you clever.

And now… the latest beer-related study finds:

4) Beer consumption after exercise improves your hydration effect……………………………….

…………………………………..not?

Why are there so many studies concerning beer? I can imagine how the idea has come about. A group of students couldn’t decide on what thesis topic to write, and one of them was just lamenting at how he would not be able to attend that keg-chugging-saturated frat party that night. Another, looking at his watch, asked the whole group to hurry up because he needed to go gym.

That was probably how the idea surfaced. If not, who in the right mind would think of whether drinking beer after exercising improves your hydration effect?!

It’s not really right to criticize studies, especially when I don’t have scientific grounds to do so. But looking at the nature of the project:

Getting 25 college students to do strenuous exercise, and then some of them given beer, the rest given same amount of water, continue cycle for months, and measure their hydration effect.

I can’t help but comment lol.

Firstly, why did they only choose college students, the very demographic that drinks and gets stoned almost every day. You would expect their body to, I don’t know, develop some resistance or positive adaptation towards beer drinking or something?

Secondly, why did they choose 25? Not only is 25 an odd number (cannot divide into 2 groups equally), it is way too small a sample size to conclude anything credible.

Therefore, while the first three wondrous effects of beer may be true, I declare the last study to be absolute bollocks. How this can make the news is unfathomable.

Then again, that, and the other benefits, are still good excuses enough to drink everyday! Yea, I guess we can all see it that way :D .

LSM2201 Project Report (First Draft) Thursday, Nov 1 2007 

In this project our team attempted to purify glutamate dehydrogenase a.k.a. GDH (an enzyme) from rat liver.

Firstly, we chopped up the liver, weighed, mashed it up and dissolved it in buffer. Then we added inorganic salt to precipitate all the organic stuff (which should include GDH) and separated the liver into 3 samples. All 3 contained much proteins, but little GDH activity. Of the 3, the 2nd one had slightly more activity than the rest.

So we chose the 2nd one and did gel filtration. Upon measuring the elution samples after gel filtration, surprisingly we had more protein than before we added in. One hypothesis was that proteins could multiply by themselves as if they were alive, while the other was that we calculated wrongly, but we still can’t figure out what is wrong at the moment.

On the other hand, GDH activity is almost nil. But of all the 20 fractions, one of them had, like, 0.0009 activity. So we chose that for ion exchange chromatography (further purification).

After ion exchange chromatography, again we had lots and lots of protein in all fractions; it’s as if we have never purified them at all. But now, GDH activity is completely zero.

After running gel electrophoresis we realised that while the crude rat liver had lots of proteins, subsequently samples have zero proteins and zero GDH.

As such, this is our report card:

Enzyme recovery : 0.00%.

Purity fold : Also 0.00%.

Agar-agar : 0 bands, and 1 ugly smear.

Sigh…. 6 MC module.. down the drain.
