Happy Birthday to Linda Ng Ching Siang

Hmm...

Inspired by a friend, I'm blogging this thing.

Happy Birthday Sis, May you be well and happy!

Thanks for helping me move my stuffs back to Malaysia.

Stop eating and going online at the same time.

Graduation To-Do List

One search on the net reveals no good general graduation to-do list. Well, I’ll do one for myself here, and then assume that it is general enough to be shared to everyone. The numeric ones are general, the finer points for me are listed.

1. Find a place to live.
• That is to pack and move my stuffs from my room and SPS back to home and the next place I'll live in Singapore. Do this before 28th April. 
• Next determine the dates I'll be in Singapore or Malaysia during the next few months and decide where and when do I get a place to live in.
• Ask around for the places to live.
2. Find a job.
• This is primary to finish the bond and loans. 
• For 3 years, I'll be doing something I like, not dislike, my no.1 condition for a job.
• Options: T.A. (do the application before I leave), R.A. (talk to people before I leave), Buddhist Jobs? (I'll still be quite active in it anyway)
3. Play
• Marvel: Avengers Alliance is my main game now,
• Pokemon trading should be done within a few days,
• Movie nights upcoming in SPS. 
• Finish up Fringe, and continuing on Avengers, Earth Mightiest Heroes, One Piece, Big Bang Theory and How I Met Your Mother.
• Presenting the Brain Band: create an event on facebook!
• Attending movie nights in Cinnamon!
• Boardgames in SPS room.
• Computer games.
4. Tie up loose ends
• Finish up some more work on my Honours Project, 
• Write that report for the Summer Research,
• Go through all the stars in my gmail,
• Finish up SPS mentor payment form,
• Check for the after graduation stuffs, for international students, Loan, Grant, Work Pass, etc...
5. Religion
• As usual, get to attend all that I can attend. 
• NUSBS Meditation Retreat,
• Tzu Chi 
• MDC
• Awaken Challenge
• Weekend visits to temples with cousin and friends
• Other Buddhist Societies events...
6. Plan for graduation trip
• My graduation trip will be back home, with NUSBS friends. Don't really appreciate the exotic places I've been to, and I really think that the trip is enriched more by company than by location. 

Preface to My Final Year Project

Thomas Precession: A Fibre Bundle Approach

The understanding of fibre bundles is essential for any theoretical physicists who are serious in thinking about the Standard Model, String Theory and beyond. That is my main motivation in choosing this project. At the end of this project, after applying fibre bundles to describe Thomas Precession, I started to wonder if this can be the start of a simple way of teaching young budding Physicists about fibre bundles. It would be one of the first few steps before progressing into quantum eld theories of gauge invariance. And yet, before
taking on this project, I had no idea that there is such a thing as Thomas Precession. So maybe it would be simple, provided that undergraduates can read this thesis and understand it.

If you need to brush up on Differential Geometry, Lie Groups, Coset Manifolds and Fibre Bundles, by all means do skim through the appendix, as it will be heavily referenced in the main paper. I would like to take this page to acknowledge the unfailing, dedicated, patient care of Dr. Kuldip Singh towards making sure that I understand this relatively di fficult branch mathematics and seeing me through the project. I had learned in this one year what most undergraduates will not: the foundations for theoretical and mathematical Physics. In this project also, I learn to see the motivation for solving a problem from the mathematical point of view instead of always asking for a physical connection. As well as the way a mathematical Physicist work.

My gratefulness extends to the Special Programme in Science (SPS), for providing such a nice and comfortable environment, both physically and socially not only for the duration of the writing of this thesis, but also for the whole of my four years being an undergraduate. Not to forget is University Scholars Programme (USP) for providing the opportunity during my final year to stay in the same building as my supervisor, making it easy to ask for guidance.

A special mention to the NUS Physics Department for having such a wide and interesting range of topics for research, and to Prof. Valerio Scarani for arranging for the Physics Honours Projects of the academic year 2011/12. Also thanks to the whole National University of Singapore for providing my undergraduate education, in one more step towards the expansion of the human knowledge, starting from the expansion of one individual.

My Undergraduate Physics

I'm here just to see what I would write, a random post that you mostly will not get too often.

So what's up? Physics has just became an important part of my life. Again. After so long. Haha. Maybe I wasn't too unhappy with the marriage with Physics. It's been 4 years since I started my undergraduate life, and although I learned a lot of Physics, I still find that the things I truly want to work on is still far out of reach.

Those things that you read on a popular science book, like a Brief History of Time, or the Elegant Universe, and most recently, the Fabric of the Cosmos (a documentary being screened in Utown in these weeks), those amazing stuffs, I only got a slight glimpse of the mathematics of it, even after knowing the concepts for so long.

It's just that before knowing the mathematics, I can fool myself into thinking that the concepts are fully explained by those popular science books or documentaries. But I know it is not true. Most of the subtleties are in the mathematics.

Now doing my final year project, I still don't understand most of the theorems that I got from the mathematics. There are just too many abstract proving to do, and that had been done by mathematicians. We physicists just look at the equations, the concepts behind the mathematics, see which part of Physics it can describe, and link them together. Or rather that is the job of a mathematical physicist. I'm kinda looking at that now. Amazing how it is done, amazing how much calculations that mathematicians leaves out after identifying the structures. Even more amazing is that after we described the phenomena using the mathematics developed by mathematicians, the engineers would have to put in the actual numbers and lots of detailed calculations for things to really work.

Well, back to the physics I learned in NUS... I did touch on cool subjects I am interested in early on. Nuclear Astrophysics, Particle Physics by 2nd year, Cosmology by 3rd year, but some of the most interesting stuffs are from the special programmes that I took like time travel in General Relativity by 2nd and 3rd semester, Black Hole information Paradox by 3rd year, and even a bonus quantum information of which I only knew about EPR and Bell's inequality before coming to NUS on my 4th, 5th and 6th semester. I have been doing amazing stuffs all along during my undergraduate years! Partly thanks to SPS and USP, mostly to Physics department of NUS, and some to Mathematics department.

Now, continuing from the studies of my 6th semester on Mathematical Methods 3, I am working on Thomas Precession, a Fibre Bundle Approach. Both terms were foreign to me before this year, and now I am half-expert on them. Half because there is just too many stuffs to read up and study before understanding either of them! It's crazy just how much I wrote for my thesis up to now. I didn't expected it to be that long! 50 pages now, and going strong, I think it might hit 70 pages. With Monday as the deadline, I better work on it now. See ya then. Now the title will be changed to My undergraduate Physics.

So overall, if you want to do Physics in NUS, not only it's not a bad choice, it's an excellent choice! Provided you're in SPS.

Multiverse Part 1: Hell, Heaven, Pure Land

It can be depressing to think that if the multiverse is infinite, then all possibilities, no matter how small, no matter how bleak, as long as it is allowed by the laws of physics in that universe, will happen in a universe.

Plus this to the fact that multiple universes does not need to remain at the same time as our universe. Some universe out there are just a microsecond slower than us, or a picosecond, or any number of time one step beyond us, all people and events happening in the exact same way as our universe.

In fact, one can think of time moving forward faster as the mind moving from one of these slower universe to another faster one. Not faster in term of time moving, but in terms of phase. And one can think of all sorts of universes out there, one with good things happening to you, and one with all sorts of bad stuffs happening to you. And it all exist and some you in some universe will experience the worst thing that can happen that is possible. While some of you in some universe will experience the best joy in the world that can happen to you.

And which universe you'll go into, which one you'll transform into, which of these future universes (that already exist, mind you) will you guide your universe into all depends on your actions right now.

That's a scary thought. And an unfair one. Why do one of you have to suffer the worst of sufferings? Can I in good conscience direct myself to the best of all possible worlds knowing some other part of me will end up in the worst of universe? Who am I to compete with myself? Albeit the me from other universes, but still, me who shares the same memory, the same feelings, the same perception, the same consciousness, just not the same choice. For it is choice that breaks the universe apart, at least in the quantum physics version of the multiverse, assuming that some how it is quantum randomness that allows for non-deterministic free will to exist in the world.

Having that kind of thought, it is easy to lose track of the meaning of life, contemplating while you may work towards the best of universes, there exists the worst of universes somewhere out there. Some where out there, someone, maybe the alternate you, is suffering the worst that can happen to a person.

Yet, had not the religions told us that hell exist? The land where no happiness ever befell anyone who is in it. If the multiverse is true, then hell is true. Not only true, but must exist. That is a scary thought. A very scary thought. No wonder some bodhisattva vowed to empty all hells before becoming a Buddha. Such compassion! Well, on the other hand, if hell exist, then heaven must exist too. For in all these multiverse, there are some universe where everyone is good towards each other, maybe even the laws of nature will allow for fruits that come from little or no effort.

If the multiverse exist, then Pureland of Buddhism must exist as well, as it is conceivable that such a place can exist, therefore it must exist, because there are infinite universes. In fact, let's not get this to be for the advantage of Buddhism alone, in some other universe, one being may have complete control over everything in that universe, due to the strange laws of physics and whatnot, so that means in that universe, the Almighty God exist.

Of course, people are rarely satisfied with just one world, some would want God to be the creator over the multiverse and have power over all of the multiverse. Of course, then since evolution make sense, and it is possible to imagine an universe where God is not necessary to create everything or anything at all, and most likely is not all powerful, then those universe must not have an absolute almighty God.

Multiverse then seems fair, it gives everyone what they wanted. What's one universe to satisfy everyone's yearn when you have infinite of them? So what's the point? We are all living conditioned by the fact that we'll all be dead someday. That life is finite, therefore meaningful. If the multiverse exist and all things are possible, can happen, has happened, will happen, what is the point of doing anything at all? Some universe will have complete knowledge of the theory of everything, some will have destroyed itself, most will be lifeless. So what?

So what if we succeed in this universe? How many more are failing in their's? Such suffering it is to have the existence of multiverse to be true that sometimes I think no one wants to think this way when they think about the multiverse, or more likely, people subconsciously still resist this idea for the very foul implications that it brings to the table.

So, tell me if you feel for your alternate selves. If you care for them. If you give a thought about them.

Enderverse

10 books in about 1 and a half months.

The books written by Orson Scott Card, settings in the futuristic world of Enderverse where genius kids were being trained to become military commanders.

Blue are the novels, red are short stories.

Of these, not reading A War of Gifts has no effect on the overall story at all.

I choose to read in the chronological order, starting with the first novel.

1. Ender's Game
2. Ender's Shadow (Note: The first 2 books take place in roughly the same time period.)
3. Shadow of the Hegemon
4. Shadow Puppets
5. Shadow of the Giant
6. Ender in Exile
7. Shadows in Flight
8. Speaker for the Dead
9. Xenocide
10. Children of the Mind

And it is very nice to do so. I get the sense of closure.

Although I got introduced into this series by randomly picking up and reading Xenocide years ago, which then needed me to read Ender's Game and Speaker for the Dead to understand half of the relevance of the book, I disliked it due to the Catholic-based Community featured in Xenocide. That was the reason for me delaying reading the rest of the series until recently. I even was determined to not put any Buddhism inside my Science fiction at all. Make it as pure as Asimov's novels. I thought.

Well, at a reread, ok, let's start from the top.

Ender's Game is about military and genius kids. Military I do not like, I detest armies. They kill and do terrible things to fellow human beings. On the other hand, I like to know more about genius kids. How do they think? What are their psychological profiles? For one of my future novels. It turns out that the training is for defeating aliens, buggers (or formics) as they had invaded Earth twice. It mostly consists of playing a game in null Gravity in Battle School. Not only bearable, but interesting. Kid genius part, Ender is more that what you can ever hope for. I can identify with Ender a lot of the time. Feeling as he felt, seeing things as he does. He's so full of good and pain and love. Well, the movie version of it is finally coming out after 28 years after the novel.

Ender's Shadow is another good read, surprisingly fresh even just after reading Ender's Game. Same story, different main character. This time it's Bean we're following. A kid even more intelligent than Ender and a lot of gaps in Ender's Game are filled up with very logical portrayal that makes one love Bean, even if Bean is still learning how to love at that time. It just goes to show how Bean is even more clever than Ender and I love the way Card did it.

Shadow of the Hegemon tells of how Ender's brother, Peter became the Hegemon in name, and in the effort of becoming Hegemon in fact. And of Achilles, Bean's nemesis, as smart as the rest of the Battle School kids, but a being of pure evil as he killed anyone who has seen him in a helpless state. Even his surgeon that healed his bad leg. This is a story of how Bean saved Petra from Achilles. The plot was a bit slow, but the world politics was awesome. Along with the trill of the face-off between Bean and Achilles... it's worthy of a Death-Note-like battle.

Shadow Puppets shows the end of Achilles at last, but not before playing with the world politics and was making Peter a puppet. Peter's come back finally got some respect from the readers for him. Bean and Petra also had 9 children of their own. This tells more about love and the meaning of a human's life: to have kids. The pain of lost kids, the monstrosity of genetic manipulations on humans, betrayals and manipulation, world politics at the balance and the final, one cold blooded murder of an evil guy.

Shadow of the Giant was a very good ending to Peter's story as he finally united most of the Earth by the time he was old and was communicating with his brother, Ender. Ender who speaks his death by writing the Hegemon. Bean has to leave Earth with 3 of his children as they would never stop growing to finally die as a giant as a side effect of being the smartest humans on Earth, a genetic defect. Petra stayed on with 5 children for the one missing child and married Peter. This tale full of tears and compassion shows that to unite the world, one has to have the world's consent to want to be united.

Ender in Exile was a good comeback to the series with Ender in it and it shows just how lovable Ender is even after one get used to loving Bean. Ender found the missing child of Bean and reunited him with Petra via the ansible, instantaneous communication. Ender has to continue to travel from world to world in light-speed as he carries with him the last surviving formic hive queen known to us at that time, planning to restore her to life. This is full of subtleties of power and politics, one tearful letter from Ender to his parents, juvenile love, and how easily Ender disarmed Achilles II, Bean's son who believed that Achilles is his father.

Shadows in Flight is about Bean and his 3 kids investigating a formic ship and found-accidentally- the cure to their non-stop growing without having to give up the super intelligence. Such as it is that 6-year olds were doing genetic research, military strategies, and spaceship maintenance. Bean, a giant finally died due to his heart failure but not before he taught his kids to live like a civilised human community, even starting up a race of homo leguminensis (after Bean's name). A cool feature of the formic was revealed, and we got a very good ending of Bean. A tale about a father's responsibility and love. Especially delicious if you read this in parallel with Ender in Exile.

Finally, the main Speaker series: Speaker for the Dead.

Having read Xenocide, I was semi-familiar with the Riberia family and the Pequeninos, the second alien race to be discovered by humans, and Jane, the mysterious entity with god-like powers. But as I enjoyed the book, what little I remembered in Xenocide didn't matter much and the whole book just speaks out to me. It's as powerful as Ender's Game is even if it is of a different genre. Finally I get to see how the Pequeninos are like and marvel at Ender, 36 years old, handle things and made a covenant with the Pequeninos to live together in the same world, in the same universe.

Xenocide, the first one that I read, and it is very rewarding to reread it. It seems that all those things that didn't make sense then had a lot of emotional impact on the novel and those that I remembered was still as good. The people in Path, the Descolada, Faster than Light travel, even the Catholic background was nothing evangelical. I guess one has to be matured enough to know how to read these kinda things. It wasn't easy putting a religious community inside the novel, and Card did it just nicely.

Children of the Mind was literally about that. As we explore the lives of young Valentine and Peter created out of Ender's mind, we finally see the danger to Lusitania averted and 2 very happily married couple in the end. Unexpected outcomes, good read and also the end for Ender as we witness his funeral and his death spoken at the last chapter in this book.

The next book in the series is Shadows Alive, to put together these 2 lines of stories, where both the main characters are now safely dead, but their children lives on. It's one of the best Science Fiction series I had read, and also one of the longest.

As awesome as Foundation and Robot series are in ideas, but better than them in characters.

Make It Right For A Better Ride

These days I go to the public transportation bringing a book or my Nintendo DSi, playing Pokemon Black. I was self-absorbed, yet almost always go to the center of the train and stood up to let someone else sit, even while reading my book. Even when I am most of the time unstable while standing up and frequently had to use one of my hand to stabilize myself and only one other hand to read.

Fortunately I am very experienced in reading with one hand. When I put my book down however, and look around, I see something very typical of Singaporeans. There was the seats that was reserved for the needy and about half of the time, young people sit there. Well, of course if there was a real case of need, they do sit up and let those pregnant, old people, disabled, or injured to sit there. Sometimes I even see old people sat up to give way for pregnant ones. As usual, most people are oblivious to this situation.

"This is normal." We think, no praises, no smile to the one who gave, only the ones who benefit directly care to smile, and then avert their gaze for the rest of the journey. Smiling, the thing I always put on my face and I keep on putting it and looking at people in the MRT straight in the eye. Most of them averted my gaze. Almost none of them smiled. The laughter and happiness that I can hear are of those teenagers or young adults talking and happily being in their own world, or the rare family who are happily playing with their children. Most of those who have kids were too busy making sure their kids shut up and behave during the train ride. Too busy making sure their kids do not offend the stranger sitting right beside them.

As if everyone you don't know behaves like a gangster to you. As if anyone can blame parents for teaching kids to be careful. Yet, this is the world where teenagers prefer to sat up even when there were empty seats, not just those priority seats, but perfectly empty seats where it is morally not wrong to sit down on them. Yet they prefer to stand up. How could those people who go beyond the boundaries of morality to beyond being polite be anything close to a gangster? How could Singapore with its low crime rate and zero tolerance towards drug harbor anything but mostly good and kind citizens of Singapore?

Yet when I look around, people do not recognize this. They do not think of others to be as virtuous as themselves. They still see those who do not let their seats to the needy, they still say go to the center of the train, they still see images of children reminding them to give way. No wonder my friends were not proud of the catchy song of "train is coming, train is coming." nor do they talk about the video of Phua Chu Kang singing to be gracious. Not that they know about all these consciously, but it is the subconscious mind being reminded that: most of these other people are not so gracious, so there's no reason to smile at them.

How I think our journeys can be made better if more people can be more considerate and gracious? I think our journey can be made better if people just stop looking at the negative side of things. Most of us already subconsciously put in the rules of being gracious into our heads. However it is impossible to smile at a stranger if we still think of them as being not gracious. The only thing we have to change is to think in the positive way.

Praise those who give way, smile whenever there is an eye contact (I know I feel weird and would look away if some stranger does that to me, but still I felt good that there is someone out there that shares my thoughts), generally open up and let the MRT be the heart of Singapore. Open up to talk to people you would never meet again in this life, open up to smile at strangers who most probably is not used to thinking of you as a good guy to smile back.

And start these kinda campaign: Look at the person beside you and smile, because they are doing their best in being gracious. Be glad to live in a society where everyone behaves heavenly.

Pokemon Black and White 2

The news had been out. The next Pokemon Games are Black and White 2. My friends were commenting that they must had ran out of colours to play with, so I was in for a shock when I discovered that it's true.

Well then, let's use some deduction ability and my hopes for the new games over here. The 2 implies that it's a sequel, so if it starts all over again, from the beginning as if it is just an improved version of Black and White, then it stinks. Pokemon Gray can do that, as there is a whole history of the 3 bundle games for each generations, but Black and White 2, should have the player to own a Black or White game first.

Then instead of the slow transfer of 6 Pokemon at a time to the new game, the save file and all Pokemon from the previous versions should be able to be transferred at a one time transfer, bringing forward every items and records from the previous Black/White games too. To avoid the need of having 2 DS for this, the Save file can be downloaded from the dreamworld itself. (Although this would mean a lot of traffic online and some possible errors and cheats from hackers)

Or the game card can be like an Action Replay game card, so one has to put the Black and White game into the Black and White 2 (bigger game card) slot and then put it together to play. Black and White 2 if designed like this should then allow the new players who doesn't have Black and White to buy them and play it out from the beginning, while for the old ones, we can just transfer everything over. In this case, there should be new maps to explore. And ranging from the most greedy to the most basic, they should include every single map of the Pokemon world, Kanto, Johto, Hoenn, Sinnoh, Sevii Islands, and Orange Islands, or just at least just one more new area for gym or contest battles.

Well, if they make the Black and White 2 to have a game card that can read other game cards, the possibility to put in the other Generation 4 Pokemon games would be nice to add in! This way, we can venture into the old maps with new 5th Gen Pokemon! Or even complete the Pokemon Transfer to the 5th Generation by transferring all of the pokemon at once instead of 6 at a time. This time I don't mind having to replay the gyms for the previous generation games. So if this happens, all they needed to add in for Black and White 2 is the Hoenn and Sevii (possibly Orange?) regions to make the Pokemon world complete!

Now that would compel an old timer to buy the sequels, and encourage the new players to buy the old games. I would assume that White 2 is needed for those with Black and Black 2 is needed for those with White. Well, I think it can be made so that it doesn't matter that the sequel needs to follow or anti-follow the previous games.

Some of the game mechanics I hope to see reintroduced is the battle contest, pokeathlon, and of course, the lead pokemon following you around! Plus the ability to make Poffin, Apricon Juice, and others....

The Black and White Kyurem might mean that Kyurem can change forms and those forms are available only in White 2 and Black 2 respectively, not too different from Deoxys' form changing from FireRed, LeafGreen, Ruby/Sapphire, and Platinum. However, this might be disappointing for most of us, as we would want to see them all. So maybe Kyurem would change form depending on the item held or perhaps with some strange interaction with Zekrom or Reshiram. And if it is items, then the item should be unique and found only in the respective games.

The most interesting part is that if Kyurem's different forms are a result of some machine that can combine 2 pokemons, then the different splicing work done over the years by many fans are able to be of use now. For we can combine any two pokemon and perhaps even choose the types available to 2 types! I don't know how evolution, move learning or separation would work then. But Smogon University would be really really busy classifying and analyzing every single combination! Most likely it wouldn't happen like this, too much work! Seriously 649 times 648= 420552. Insane work and insane amount of battle mechanics.

Well, at least we know we'll get to see the story of where Ghetsis had gone to, what does the underwater ruins sayings means, and the story about Kyurem's original form. Hopefully, they throw in the last 3 Legendaries of the Unova region. Or at least give it out via Wi-fi or Dream World as promotional pokemon!

Love

I've been reading Ender's series by Orson Scott Card lately, and in it I find a truth that mankind does find one of the highest happiness in mundane live is the holiness in the love between two person. He puts it in the sense of the purpose of living is to love and breed. Why would anyone want to become celibate?

I've been reading the Rave Master Manga too and there is surprisingly a lot of things that I learned over there.

One of the few things is that love is such a powerful force of motivation, it can keep one person to keep on fighting for 50 years. Even love for a person whom you believed to be dead.

Even the Buddha was searching for the truth out of love for all beings in the world. As the motivation goes on, love is the one that can get one to go the distance, and once the river is crossed, it is time to let all attachments go. Yet, compassion and loving-kindness remains, therefore the Buddha came to teach us what to develop in order to see the truth.

Now I know why had I allowed myself to fall in love. I needed more than just theoretical knowledge of all these. I needed the experience, the emotions, the motivations, the hurt, the pain, the understanding of these. I needed to know what I was planning to let go of. I needed to know why did I choose to live such hardships.

It was a risk to fall in love, but I wouldn't regret the outcome either way. Now I know why I'm not regretting this outcome.

NUS Module Review: SP2170 - Doing Science (retired)

Content
With a different lecture each week and fun IS, along with the free S/U, this module introduces one to the world of scientific research and does it very well with the system of 3rd and 4th year students as mentors to guide the first year students.

Assessment and workload
Completely S/U, as long as you attend the lectures and IS, do the experiments and homework, plus one self-designed experiment, you'll guaranteed to pass. Well it does has the reputation of making people sleep over at SPS room to rush for homework!

Personal experience
The best module in NUS! Slackest amongst SPS modules too! Sweet memories!
