4 papers down, one to go. Just had my particle physics paper this morning, and my final paper will be on next Thursday, so a bit of time to prepare.

So far the exams have really been going well. I must done only about 50% of the preparation I did in previous years, but so far the papers I've done seemed pretty easy, especially since my last-minute preparation has consisted mostly of playing PS2 the night before my exams.

At least 3 of the papers 'feel' like 90+% papers, which should be sufficient to ensure that I finish top in class.

Mission accomplished I guess, although I want to ensure I do well in my last paper as well.

In the past couple of weeks, there has been some drama in my student residence (Netherhall), concerning this guy whom we'll call 'B'.

B in the same department and same year as I am (he does physics, but we only share a couple of classes), and he's been slightly antisocial and weird since I first known him, but his behaviour has been deteriorating in recent weeks. B has shown signs of jealousy of me in the past, e.g. by telling people that I get good grades only because I take easy courses, and I haven't been very compromising with him either whenever he tries to show off by babbling random pseudo-physics nonsense to try and impress people.

But recently he has been become increasingly weirder...since I'm not on good terms with him, I have had little direct contact with him. I've heard from many different people about his antics, but here are a few choice ones:

1. The first sign of his decline was a couple of weeks ago, when he told a friend of mine during dinner that 'Princeton is shit'. It's one thing to be jealous of me getting to study there, but he has to be near the edge to make such a ludicrous statement.

2. My Spanish friend Pedro was once on the Underground with his girlfriend when B happened to be on the same train and spotted them. He went over to them and sat next to them without saying anything, and he was staring at them for the entire journey. When Pedro said 'Hi B', he didn't respond. Later that day, when Pedro came into our library downstairs, B was there. B saw him and started chanting under his breath 'Fucking Spanish, fucking Spanish, fucking Spanish...'

3. B is half-German, and last week he started telling my Nigerian friend, Chema, about how blacks were inferior and Aryans are the superior race. Chema was surprised and retorted that as a 'mongrel' race B would have been one of the first to be sent to the concentration camps. Naturally, this didn't sit too well with B and he stormed off.

4. Amer is one of my best friends here, and we've both been familiar with B's antics for some time. A couple of days ago Amer was chatting with another friend, Reuven, about girls when B came along and sat near them. Amer felt uncomfortable and left shortly afterwards, after which B started asking Reuven detailed questions about the girls from the prior conversation which obviosly irritated Reuven. Suddenly B changed tack and asked Reuven: 'What has Amer been saying about me behind my back?' (B has never spoken to Reuven before this). Reuven was shocked and said (truthfully) that they never talk about B He refused to believed this and kept insisting, and Reuven just said they don't talk about him. B then said 'You're lying' and walked away.

All this happened within 2 weeks ago. I suspect that he is cracking under the pressure of exam pressure and his deep jealousy of me, but he's really started to act completely weird. To make things more interesting, someone spotted him walking around at night carrying a knife. Maybe he was just going to cut some food, but at night....?

Some days ago, he moved out of Netherhall. Apparently he told the director that some of us were bullying him (including the chaplain !), and he was afraid that someone might try to rape him!

I don't know where he is living now, but he seems like he's losing it (assuming he hasn't lost it already). Many of us have tried to help him, but when he doesn't want to accept our efforts, there's nothing more we can do.

There are 'friends' who only ever contact me when they need something from me. Whenever I get a phone call or text message from these people, it's usually when they need something, whether to borrow my notes, asking for my help with homework or to ask for advice.

Don't get me wrong, I would always help people if I can, even if the person asking isn't on good terms with me. But it'll be nice if I get some sort of acknowledgement apart from a perfunctory 'Thanks', even if it's just an occasional text or e-mail saying hi.

As it is, I start to feel like I'm being used.

Mostly studying for my finals these days, which begin next Friday. Nothing much to talk about on that front apart from the fact that I am indeed making progress on my revision, although not as intense as in past years.

I actually managed to get some music squeezed into my schedule before my bedtimes, whereas in previous years my Easter break has been a time of musical abstinence. The interesting thing I find about music is that it makes the greatest impact when it's special. Playing for the first time in a month feels a lot more special than practising for the 6th time in a week (although playing merely once a month is hardly a recipe for advancement).

Hopefully during summer I won't be too distracted by the World Cup etc., and put in some time for disciplined practice on my guitar. I can feel the next breakthrough in my playing ability approaching, and a burst of intensive work should bring that about.

I've come to realise that the ego is the greatest obstacle to music-making.

At the most practical level, the existence of ego translates to stage-fright: when I realise that I'm going to be playing in front of an audience, there is the egoistic fear of making mistakes in front other people, or not playing at my best and causing people to think badly of me. Because of this, I start to focus too much on getting the right notes rather than on the overall musical and emotional content of the piece. The funny thing is that this often backfires: the more I think about what are the notes I have to play, the more likely I am to suffer a memory lapse. Even if no mistakes occur, the resulting performance would be mechanical and lifeless.

My best music is always produced when I'm playing on my own, without any feelings of self-consciousness or nervousness. Somehow, this just frees me to play the best music I ever make.

I love playing music for other people, but somehow this I get the feeling that my audience will never enjoy my music as much as I enjoy my own playing when I'm alone.

I've just about managed to get settled down into the schedule of cramming for my finals, which begin on the 28th of April and will be over by the 17th of May.

I had drawn up a comprehensive schedule for my revision before I visited the US a fortnight ago, but it was only several days after my return that I managed to shake off my jetlag and excitement (from the visit and the prospect of studying in Princeton) to hit the books. In previous years, I have hit the books the moment Easter Break started, so this time I'm about 10 days behind compared with back then.

There also the psychological effect of being aware that the results of this exam wouldn't be crucial to my future, since I already have the place at Princeton; however I should make sure that I finish top in my class (which is a rather important bit in anyone's CV), but on the other hand I don't have to push as hard as in years gone by.

Conversely, a couple of the courses I'm taking this year have turned out to be very interesting and fascinating (see one of my past posts on my other blog), so I want to make sure I understand the subtleties of these subjects if for no other reason than my own curiosity.

Perhaps these two effects will cancel out and I'll end up doing not very differently from my earlier years.

OK...the pics from my campus-scouting trip:

Purely for the record....

And it's official that UC Santa Cruz has rejected me!

From Princeton, I took the train to NY Penn Station where I caught a train to Boston (I'm rather proud to state that I spent all of 15 minutes above ground in NYC, to buy a mobile phone charger). The train journey was very nice because we were travelling through the New England countryside around sunset, and the scenery was like something out of a landscape painting.

By the time I got to Boston it was in the night, so I didn't go over to the Center for Astrophysics (CfA) at Harvard until the next morning. Whereas the astrophysics department in Princeton was enclosed in a fairly small building, the CfA in Harvard is huge. It's a 4-storey building holding over 300 PhD researchers (apparently the largest concentration of PhDs in the world!), although a lot of them work for the Smithsonian Observatory which isn't officially part of Harvard.

Just like at Princeton, it was arranged for me to meet up with some of the professors. There were not that many professors at Harvard who were doing cosmology, and I got to talk to 4 of them. The rest of the professors I talked to were in X-ray astrophysics, which I considered rather strange since I specifically stated in my application that I was interested in cosmology for my PhD even though the bulk of my prior research was in X-ray work.

The cosmology profs at Harvard were doing some interesting work, but I felt that they were less enthusiastic about me than Princeton, and some of the current grad students there told me that some of them were difficult to work with. Speaking of the grad students, I managed to speak to quite a few of them, and they were asked to bring me out for lunch and dinner, and to show me around town. They bought me my meals, which the department would later reimburse them for (in fact the department would pay for the students as well, which made them quite happy to come).

Boston is very close to Harvard, less than 10 minutes away by subway. It is a pretty nice and pleasant city, not too big, and I was fortunate enough to come just at the beginning of spring where the weather was nice and sunny. Most of the tourist attractions seem to stem for the historical significance of the city during the Revolutionary Wars, which wasn't as interesting for me as it would be for American visitors, but I did enjoy having decent seafood for my meals.

In the end, however, I decided to choose Princeton. In pure academic reputation, both Harvard and Princeton were probably just about equal, but I preferred the small size of the Princeton department which meant I would be able to know everyone there, whereas I would just get lost in Harvard CfA. Also, in Princeton I would be close to their world-class physics department as well as the Institute of Advanced Studies, Einstein's old stomping ground, which would enrich my education.

Apparently there were 5 students this year who were admission into both Princeton and Harvard, and 4 of them have decided to go to Harvard. I must be say that I found my trip to Harvard/Boston particularly enjoyable, and I enjoyed the company of their students. The Princeton students were nice as well, but I didn't get to hang out with them much apart from one dinner. Indeed, if I was looking for a place where I would have fun and enjoy life, I would probably have chosen Harvard assuming they're equal in academic factors.

A ridiculously important decision in my life, but at least I got to take a look personally before I made my choice. Check back in a few days to see the pics from my trip.

I've been treated like a prince in Princeton. I'm writing this in my hotel room on my final night here, but it's been a very eventful journey so far.

The flight here was one of the worst I have ever taken. I was flying BA a.k.a. ''Bloody Awful' from Shitrow Terminal 4, and surprise surprise, we took off an hour late. I may have accumulated about 3 round-the-world-trip worth of air-miles over the past few years,but for the 1st time in my life I was treated to an aborted landing. The plane was about 10 feet above the runway at Newark when the pilot hit full throttle and pulled up, so we had to go around for another approach. On terra firma, I was pulled aside at immigration for additional processing, simply because Malaysia is apparently a terrorist nation according to the forever-brilliant US authorities. So when I finally got nto Princeton at 2.30pm, it was about 3 hours later than I had intended.

Princeton itself is a nice, if small, colonial town, and I won't describe it more because pics will be up when I get back to London. When I got into the astrophysics department, Charlotte the student admin offered to go out and get me a sandwich. Embarrassed and shy, I tried to refuse but she insisted. I was taken to meet Jim Stone the graduate admissions chairman, and he told me about their programme. I attended a talk by a professor from UPenn which the rest of the department attended as well, which was interesting because it was about cosmology, my field of interest, although I didn't understand all of it. In the evening, I had dinner with the visiting professor, a Princeton professor and several students.

Most of today was occupied with meeting wth literally half of their faculty (the department here is very small, only about 15 professors). I met them individually for about 30 minutes each, and we discussed both my interests and their research (as it turns out, mostly the latter). Some of these guys literally wrote the book on their respective fields, and I was impressed that they cared enough about getting good students that they spared time for me, even if I may not end up working for them, or indeed not choose Princeton at all.Everyone was nice and friendly, but it was immediately obvious they really are world experts at what they do. A couple of them had interesting characters as well. Robert Lupton is a pony-tailed Englishman who goes around barefoot (yes, barefoot!), and has not lost his dry English sense of humour despite several decades here. Another was Rich Gott, who has intense eyes (as in there is a glint in them) and spent our meeting telling weird stories in addition to giving an impassioned extolation of Princeton's virtues. i later learned from the grad students that he has been known to rant at students for 5 hours nonstop, and likes writing papers on topics like time-travel and aliens.

During the breaks in my schedule, I had the opportunity to mix with the students, and they brought me out for dinner as well. They told me about the student life here as well as telling the not-so-good things here, which shows that they were being frank.They were a nice bunch and I got on well with them.

I'm off to Boston tomorrow to visit Harvard, and it'll be interesting to see how that place contrasts with Princeton.

Yesterday evening, I took out my guitar for Mikhail the Romanian guy to take a look (see previous post). He's been playing since he was 10, but hasn't played for the past 2 years. In fact, he doesn't even keep long nails anymore.

After I played him a couple of pieces (I'm a bit rusty as well as I haven't been practising regularly in some time), I handed him the guitar for him to try. The moment he started playing I could tell that he's a very good guitarist, even if he's really rusty, more so than I am.

He played parts of a couple of pieces (as he forgot them halfway through), then to my surprised he started to play Bach's D minor Chaconne (a properly played version can be heard here), one of the most difficult (both technically and musically) pieces in the classical guitar repertoire. He was playing quite hesitantly and with mistakes, but considering that he hasn't played for a couple of years, it was pretty damn impressive.

Before I continue, I should admit that I'm usually a lousy listener; I have fallen asleep at concerts before, and even when I don't chances are my mind will get distracted and I don't fully appreciate the music. However, with this guy playing the piece in front of me, even if in a rusty way, I found myself following every note and internalising the music. While his playing was imperfect, this was the first time I truly saw the beauty of the Chaconne even though I've heard it many times.

Later in the night, I put on a recording of the Chaconne to try and recapture the beauty again, but it just seemed flat and lifeless.

This just goes to show that music is ultimately a means of communication: I had never spoken to a Romanian before, and yet this stranger could open my eyes to a beauty that I could never perceive before.

I'll be in the US for the rest of this week, so there won't be any new posts till I get back!

I was having lunch in the dining room today, and I sat in front of a new person I've never seen before. We started off a conversation, and I learned that he was Mikhail (sp?) from Romania, and that he was around in London for a job interview.

After a pause in the conversation, he suddenly asked me, 'Are you a guitar player?'. I was surprised and more than a bit discomfitted, and replied in the affirmative. I asked him how he knew, and he said that he noticed my right-hand fingernails were long.

It's kind of like a secret sign for a mysterious brotherhood, that 'brothers' can recognise each other even when they don't know each other.

Fact of the day: there is apparently a Chinatown in Lagos, Nigeria!

Term is over. I've finished my last term of lectures at UCL.

Today was the last day, and I went into college just to hand in the two copies of my project report. The project itself has been fairly dull and boring, mostly involving writing code and debugging it. My supervisor wasn't around for nearly half of the duration, and he said that getting the project done effectively on my own would boost my self-confidence. It didn't really boost my confidence because it mostly involved things which I knew I was good at, i.e. plain simple getting-things-done and problem-solving skills.

My self-doubts about my mathematical abilities were only exacerbated because most of the background science on the project were beyond my abilities; while I didn't really need to know about those things, the fact that it's there and I can't understand it makes me feel uneasy. I guess it's part of the scientist side of me that feels uncomfortable if there are any stones that have been left unturned.

I was feeling bored and frustrated by project over the past couple of months, and the writing of the report in the last fortnight was just totally uninspired. I just couldn't really be bothered with it anymore, although admittedly there were other distractions which were putting me off it. Last year, I had finished writing the report 3 days in advance of the deadline; this time, I finished writing it 11pm last night, and it was due today.

I'm very glad that project is over and done with. I don't think I'll get great marks for it, so I need to knuckle down and cram for my finals in May. Before I start cramming however, there will be a brief interlude to the US from next Tuesday till Sunday.

These days, when it seems as if I'm ahead of things, I start getting lazy and slacking off rather than going for the kill and finishing it off. It's a bad habit.

I gave an after-dinner talk on cosmology to the residents of my hall on Monday. This was actually only the second time I had given a science talk to a 'lay' audience, the first time being some two years ago in '04, when I gave a talk to some students at my old high-school. In fact, the PowerPoint presentation I used on Monday was modified and refined from the high-school talk. I have given many more talks since the one in 2004, and the experience led me to shorten the talk (my rule of thumb is 1.5 minute per slide) and remove all the custom animations (i.e. having to click to bring out individual sentences). I also made some clarifications and corrections to the material based on the extra two years of knowledge I had gained.

The run-up to the talk wasn't ideal.... most of the Circle, Hammersmith and Metropolitan line was down due to signal failure, and I only got back to Netherhall from uni at around 7.15pm when the talk was supposed to be at 7.30. After forcing down my dinner, I went down to the coffee lounge with my laptop only to find that no one had bothered to set up the projector and screen.

After these technical difficulties were resolved, I finally got going. The audience was fairly good, with about 30 people in the room from my rough estimate. I started off with a historical overview of humankind's view of the cosmos, from the early beliefs about a geocentric universe
of the Sun and other bodies orbiting the Earth, through Copernicus, Kepler and Galileo's discoveries which shed light on the actual arrangement of the Solar System.

I then fast-forwarded to the early 20th century to describe the next great change in our understanding of the cosmos: Hubble's discovery that our galaxy was not unique, and his subsequent discovery of the expansion of the universe. This was followed with a brief description of the nature of this expansion, and then about the cosmic microwave background which wrapped up the talk.

When I finished, I got quite a few sensible questions from the audience, which was gratifying because it meant that my talk wasn't totally beyond them.

The presentation itself was a good one, but I felt that my delivery was rather bad. Considering that I used to be a debater for my high-school, I felt that my talk was quite disjointed and inarticulate. Several times I confused myself in trying to explain things without resorting to technical terms, which disrupted the flow. I think that in the future, I need to use cue-cards to ensure that I deliver everything I intend to say, and to keep my mind focused.

After the talk was over, I got some thank-yous and congratulations from my fellow residents. One positive comment was: 'I didn't understand everything you said, but more than I normally would'. It was clear that the subject matter of my talk was fascinating to laypeople, and that the structure of my talk was at least good enough to keep their interest. However, I think that my verbal delivery needs to be polished to give more eloquence and articulation.

When I go back to Malaysia during summer, I will try to arrange a few talks in some schools. I've managed to hold the attentions of a group of grown adults, so we'll see how successful I am in trying to reach out to teenagers.

Andres Segovia apparently once said: 'If you practise music for more than 3 hours a day, you will not be unhappy'.

I think he's right.

Last night I decided to join some of my friends to help hand out food to homeless people in Holborn. I'm rather ashamed to say that it must have been a year since I've done any volunteer or charity work, but it's a sad fact that most of the intervening time I've been too busy to even contemplate doing such work, let along go out and do it.

After dinner around 7pm, Jason, Reuven, Alvaro and I went over to Holborn close to LSE. We were originally supposed to first go to Bond St. to help pack the food, but we were a bit late so we were told to go straight to Holborn where it would be distributed. We got there at around half-past, and although the food van wasn't due to arrive until 8pm, there was already a crowd of homeless people milling about. I must say I felt vaguely uncomfortable, as usually one sees homeless people in ones or twos but not a whole crowd of them. It might also be something to do with the fact that homeless people tend not to put personal hygiene very high on the priority list.

In any case, we waited in the chilly evening air until the van arrived. The moment the van arrived, the homeless people started crowding the vehicle as the organisers (not very successfully) tried to get the crowd into a queue. I joined in to hand out the sandwiches and miscellaneous items (which were obviously products about to go off and donated by supermarkets). There was something vaguely resembling a queue by now, but still there were people trying to cut in, and it was disruptive when people requested for specific things ('Do you have a bacon sandwich' etc). The behaviour of the people were rather varied....some of them were polite and thanked us, while others were demanding and brusque. I can understand that their life isn't very peachy, but surely it can't be too difficult to at least try and be a bit more civillised (to be fair, some of them were probably not in full control of their mental faculties).

I particularly felt for a guy in a wheel-chair who could not join in the crush... by the time the crowd had thinned out enough for him to get food, there were only bread-rolls left. Still, he seemed very grateful for what we could give him, which made me wish even more that we had more to give.

I was treated to a show of bureaucratic 'logic' today. I went to apply for a visa for my 5-day trip to the US at the end of this month (which incidentally went quite well, as I only waited a bit more than 2 hours, mostly indoors, compared with 3 1/2 hours shivering outside 2 years ago).

The last time I went to US was for my STScI internship in Baltimore back in '04, and I had all the supporting documentation and forms from STScI to support my visa application. The internship was supposed to be 10 weeks, and the embassy granted me a visa which lasted about 5 months. This time, I am travelling to the US for 5 days, and the embassy officer informed me that he was granting me a visa for the duration of......1 year.

I would like to remind all and sundry that my other blog is regularly updated as well, and I'm rather tired of double-posting material from there over here (this blog is only intended for people who know me personally, and I intend on making this dichotomy more clear from now on in my posts). So my opinions on science and physics would go into that blog, while more personal stuff remains here.

I am not a morning person, period. Back when I was in school, I waking up at 6.30am was a daily struggle. For my parents, on the other hand, it was a natural thing to do. My father wakes up every day at 7am to practise Tai Chi, and my mother wakes up around that time as well. I, on the other had, could rarely get up before noon if there is no particular reason to.

In the middle of night, on the other hand, my brain activity seems to fire up. I enjoy studying in the peace and quiet of the night, with no distractions to bother me. I took this to a rather weird extreme during the Easter break of my first year in uni, when I was studying late at night and waking up rather late in the day as well, with the additional caveat that I started sleeping and waking up later every day. After a couple of weeks, I had reached the point of going to bed at 9am and waking up at 4pm (!). This was rather disorienting, if for no reason other than the fact that I had no idea what meals I should be taking, and eventually I did fall ill from this, I suspect from a combination of this punishing studying regime and the spring flu spreading around.

Nowadays, I have reached a fairly happy compromise of going to bed at about 2am, and waking up before 10 to study. In Netherhall, we are required to vacate our rooms at around 10.15am for cleaning to be done, so I'm forced to get up no matter how lazy I'm feeling.

This few weeks ahead are going to be nasty, however. I have my research project dateline coming up in 3 weeks, and I submit my project report of about 10,000 words by the 24th, and a major headache is that the code I'm working with is still buggy, and the run-time of the code itself is extremely slow. I actually enjoys studying the material I'm learning in my lectures now, however I cannot afford to let my project slip up. I may have no real competitors for top student in my department, but standards have to be maintained...
