One Fine Year

Last two weeks was a really difficult time for a ‘normal breathing’. As I did mention in my last post, both PERFIK and ESL 5 event has now finally come to an end.

PERFIK, 6-7 Dec06’- Both of us (together with my friend) was arriving late and missed the officiating ceremony at the Palace of Golden Horses. She just happened to print up her poster on the morning of 6^th Dec. And I was like trying very hard to control my feeling towards the fact that I’m going to be the 1^st presenter during the evening session on that very 1^st day. Two days before PERFIK I managed to prepare my full paper (one day) to be submitted during the registration and also my presentation slides (one day). My supervisor who was also the committee of the PERFIK had making ‘sound’ about the full paper and in the same time asking about the preparation for ELS 5. I was so relieved and happy that I’m not part of the PERFIK organizer. If not, my life would become an ultimately disastrous. Years I’ve been into the experience of organizer (plus participant) contributor. And I must say that becoming a purely participant was really cool. Nothing to worry and less of thinking about organizing stuffs...The morning session was started by a plenary session by two-invited speaker. The first was talking about “Microstructural Evolution in Ceramics: The Key to Property Control” which I found the talk very interesting due to his colorful slides and images but sadly I don’t understand a thing. I mean if I want to really get excited with the content. Second was more to my field. Taking into account that his work involved quantum mechanics per se where his slide’s content, includes theoretical work, equations which I recognized and so on. But again, it was so high level that I think that most of us would like to have time in completely understand it all. And, finally during my time of presenting, it’s running smoothly. Some Q&A and also had a chance to listen to new research by other presenter as well. Two days of absorbing kind of thing…

ELS 5, 12-15 Dec06’ – Apart that we facing lots of difficulties especially at the very last minute, including one of our speaker was calling it off for emergency, I might say that overall ELS 5 was a success. Personally, from my observations, speakers are really enjoying their time during their stay. Participants were totally giving their full support to every 4 consecutives days of lectures series. And for myself, I managed to discuss my work with one of the speaker. I’m really great full to that. Since his research was part of what I’m doing right now. I was able to ask him whether my whole idea was correct and I was also able to find techniques (especially mathematical tools) on encountering the problem. I was even more great full to find that the speaker was much a helpful to myself. During the two last days of lecture series, we have 2-3 hours of discussing. He was trying hard to give me in that short period of time as many things as he can. And with that attitude, all of a sudden I becoming energetic and just can’t get enough of it. But I was trying hard to follow his explanations and ideas. And later that evening while at home, I got a headache. Believed or not... Still, I'm quite amazed and wondered how overseas researcher pull up to a maximum level of their stamina in doing research. Sorry to highlight this but truly speaking, well… they work like hell.

Conclusion – this week would be my week of all. Coming soon, will be the celebration of X’mas holiday and next week was meant for Hari Raya Qurban. And it is also the countdown to year of 2007. So, what we're heading next?

Sayonara 2006...

Heading Where

Woww...it's been a very long long gap.
What I've been up to lately?
It's like I'm having a very own narrow of life...me.
I have to admit that I can easily get tired nowadays (really I am). Especially when I’m focusing with my stuffs seriously for the whole day. I can actually get dizzy sometimes but water really help me a lot. Yes, plus, I've been quite bundle up with the facts that next week I have short presentation to give to (national physics conference, how well did I prepare for this?) and another which is on the week after the conference we’re organizing our 5^th series of seminar involving outside speaker. Which in my part I have to prepare the forwarding text draft for the chairman and the officiator during the opening ceremony. Tell the truth, I kind of really don't like about having writing the draft. It can sometime take lots of my time (done it with 2 hours for two texts) and furthermore it could scratch my head too. Still, as an ultimate pure courage person is supervising me, I might say that, this task is worth doing. I mean the experience and also the extra extra knowledge (again being positive).

This year, our theme for the ELS 5 is on the "computational physical sciences". Its an interdisciplinary area at the intersection of three domains namely mathematics, computer science and biological and physical sciences (the chemist are there too). It’s very powerful that nowadays, scientist can have a possible new and powerful way of doing science. Promises are, we can deal with an accurate progress between the theory and experimental results. To think of it, scientists and engineers should be able to coupe with a higher state of development in technologies and knowledge involving computational sciences. It’s not just about using the computer but its more than that. Talk more and more, sometimes making me confuse on what I really like to be specialized in. At first, I’m just happy with maths, since at the infant level I work on a very nice interesting math works (really happy with), but in the following final year of my degree I start to jump into the physical interpretation (little have been touched) plus math works (again) a.k.a. mathematical physics. Now during my furthering, the math works are not simply the way I used to play around with. Numbers are rarely seeing while abstract figures are everywhere to found. Sentences are not supposed to be the way we have it but it’s the other way around. First thinking is not applicable yet thinks more and more is just a must thing to do. I get stuck here and there and smooth route was sometimes hardly to find. What a journey…its like Mr. Frodo’s journey in trying to destroy the one RING. But he succeeded anyway.

Once told me that theoretical physics are very wide area and now the computational method are there also. COMPLETE structure. Just look at the circles, its obvious right? I just have to admit that what I’m doing now is something more than I ever imagine. It’s more (I think I need a shoulder to cry on). Long time ago, during our studies me and my roommate used to imagine ourselves being in a very fun work environment having no much load to our brains. In reality, I’m facing this circumstance where much supports are really appreciated. Still, goods things happen from goods desire. I am very much believed in it.

Lets hope...

Apa Itu Fizik Teori

Ahli Fizik teori menggunakan matematik untuk memerihalkan konsep semesta (alam) dan antara saintis teori ulung pertama yang amat terkenal ialah Sir Isaac Newton. Sumbangan terbesar Newton adalah dengan pengenalan kepada kalkulus (calculus). Suatu subjek yang amat penting dalam matematik. Semasa era Newton, ramai yang telah mengetahui kepelbagaian penggunaan konsep aljabar (algebra) dan geometri. Kedua-dua konsep ini amat berpengaruh dalam penghasilan rekaan-rekaan terutamanya dalam pembinaan (architecture). Namun konsep tersebut hanyalah boleh memerihalkan perkara-perkara ataupun objek-objek yang dalam keadaan pegun atau rehat. Ini adalah kerana aljabar dan geometri adalah sangat berguna dalam menerangkan saiz sesuatu objek. Kedua-dua konsep aljabar dan geometri ini didapati gagal dalam menerangkan objek-objek yang bergerak, berayun ataupun perubahan-perubahan yang dialami oleh objek berkenaan dalam satu-satu masa. Maka, tindakan Newton mengaplikasi kalkulus amatlah berguna. Dan antara contoh-contoh mudah yang boleh dilihat oleh manusia sendiri dengan mata kasar ialah berkenaan pergerakan matahari, bulan, planet-planet dan juga bintang-bintang. Gerakan-gerakan objek ini memang menimbulkan minat kepada ahli astrologi umumnya untuk memahami pergerakan alam semesta.

Newton kemudiannya memperkenalkan kalkulus yang menggabungkan konsep beliau iaitu Hukum Gerakan Newton dan seterusnya menghasilkan model matematik untuk daya graviti yang bukan sahaja memerihalkan gerakan-gerakan planet dan bintang pada malam hari malah konsep beliau mampu menerangkan berat ayunan dan bebola seperti yang dijalankan dalam ujikaji-ujikaji mudah pada hari ini. Semuanya hanyalah menggunakan persamaan-persamaan daripada Gerakan Newton yang diperluaskan lagi. Bermula disini, konsep fizik bagi setiap objek bergerak mampu diterjemahkan dan seterusnya banyaklah eksploitasi sains fizikal daripada penemuan ini.

Kini fizik teori telah diperluaskan bidang kerjanya dalam ruang tentu matematik untuk mencipta matematik baru seperti yang dilakukan oleh Newton dengan kalkulus yang mana beliau meluaskan Hukum Gerakan sedia ada kepada konsep matematik yang lebih luas penciriannya. Dan Hukum Gerakan Newton ini merupakan contoh fizik teori yang paling penting dalam memerihalkan alam semesta dan segala pergerakan di dalamnya dengan berlandaskan perantara matematik. Pencerapan yang dilakukan dengan memahami ‘bahasa’ matematik itu sendiri adalah suatu yang abstrak dan amat berbeza dengan eksperimen yang mana cerapan adalah berbentuk nyata dan menampakan bentuk fizikalnya.

Oleh demikian panggilan fizik teori lebih bermiripkan kepada cerapan secara abstrak seiring dengan penerangan konsep fizikalnya yang berkesan.

Apa itu Nombor Kuantum?

Nombor kuantum boleh dikategorikan sebagai salah satu topik yang penting dalam mempelajari subjek mekanik kuantum atau umumnya teori kuantum. Namun hingga kini, ramai yang masih keliru atau masih menginginkan penjelasan menyeluruh berkenaan nombor kuantum ini. Maka, inisiatif ini diambil bertujuan untuk memberikan gambaran malah pemahaman padu berkenaan nombor kuantum. Beberapa istilah yang digunakan adalah istilah biasa yang telah pun diperkenalkan dalam subjek mekanik kuantum (adalah lebih berkesan jika pembaca telah pun memahami istilah-istilah tersebut).

Istilah nombor kuantum muncul apabila ingin mencari penyelesaian kepada persamaan Schrodinger. Persamaan Schrodinger ini adalah persamaan gelombang dalam fungsi gelombang untuk mencirikan sesuatu zarah pada sesuatu titik dalam satu-satu masa. Adalah diketahui umum, mekanik kuantum mementingkan ruang kompleks sebagai sistem kerja berbanding mekanik klasik yang lebih kepada ruang nyata. Dan persamaan Schrodinger yang diperkenalkan oleh Erwin Schrodinger (ahli fizik terkenal) dilihat sebagai satu-satunya persamaan paling berkesan untuk mencirikan sesuatu zarah dalam ruang kompleks itu. Dengan berpandukan kepada sesuatu situasi kompleks berkenaan terdapat beberapa nombor kuantum yang boleh dikira. Sebagai contoh, dalam ujikani osilator harmonik (ujikaji satu dimensi zarah yang dipengaruhi oleh keupayaan V=[1/2]kx²), nombor kuantum yang terlibat adalah n, yang mana n ini mewakili paras tenaga (energy level) kepada osilator harmonik.

Satu lagi contoh adalah dalam tiga dimensi untuk satu elektron bagi atom, nombor kuantum yang terlibat adalah n, l dan ml. Ketiga-tiganya mewakili paras tenaga (energy level), momentum sudut (angular momentum) dan momen sudut (angular momen) kesemuanya pada arah paksi z. Terdapat satu lagi nombor kuantum iaitu ms yang mewakili spin elektron.

Jika berpandukan contoh-contoh diatas, dapat diperhatikan bahawa nombor kuantum adalah sesuatu yang diskrit (denumerable) atau sesuatu yang boleh dikira. Hanya perlu meluaskan lagi situasi kompleks (sistem kerja kompleks) sedia ada, maka kita akan dapat mencari atau mengklasifikasikan nombor-nombor kuantum yang mewakili perwakilan-perwakilan tertentu. Dan ini memang sesuatu yang boleh berlaku.

Nota: kesemua ujikaji merupakan masalah penyelesaian kepada
persamaan Shcrodinger

Theoretical Sciences League

It’s now a fact that no more TSL (Theoretical Studies Laboratory). It’s been officially announced by the senate that our lab will be exiled from our previous place and now we recite under the physics department. Still we keep on maintaining the plan for having the next TSL ELS V (namely Theoretical Studies Laboratory, Expository Lecture Series) due on the 12^th – 15^th December 2006 carries the theme “Computational Physical Sciences 2006”. Formerly our ELS I, II, III and IV has successfully create positive response from local researchers especially the theorist. So it’s really a good thing to have the lecture series being continued. Then today we resume our 3^rd meeting of the committee. And funny thing that we’ve come up with a new name of TSL where everyone kind of agree with it. So instead of Theoretical Studies Laboratory we agreed on Theoretical Sciences League (reminds me of the cartoon Justice League). For me it’s a very cool name. Well, it suppose to be that way. Better hope that it will bring more joyous and prosperous to the group.

Reign by the Azzurris

The World Cup 2006, Germany has now ended (Olympiastadion - Berlin). And the winner, as I’m dying want it to be was ITALY…, which make France fulfilling the second title. Not once, ever imagine that the Azzurri can actually be the 2006 winner. This is their 4^th winning for the World Cup after few years back with a ‘heartbreaking’ journey. Believe it or not the fact that with all their previous defeated was now prevail with a big of a winning celebration. It’s really remarkable. And thank must goes to the ‘only’ David Trezeguet (the one who crash out Italy dream in the EURO 2000 with his golden ball) for not to be able handling his penalty accordingly. Where as for the Italy, they completed the 5 penalties elegantly…

I must say that during the match, the two of us was kind of hoping that both of our team could make it in claiming the winner title. I was totally nervous about Italy becoming the winner, since France can actually creating bizarre and dangerous attacks while they in the field. Not to mention that they did have a tiptop well-known player in every position, Henry (forward), Zidane (midfield), Thuram (defend) and last man Barthez (keeper). This not happen among the Italians. Very few of them are recognizable, while the others were just an ordinary player. Still, last night game was fantastic (sorry that I was actually ‘on’ and ‘off’ while watching), but the game was really full of a drama. The top story would be, Zidane's shocking red card penalties in his 108 caps of international appearance. Instead of ending his international carrier gracefully, he just have to accept the fact that it’s the other way around. Another was, the game itself. France did actually have beautiful chances to ‘break’ Italy’s net, but all of their ‘trying’ being denied by the Italians whole-heartedly. Buffon (Italy’s keeper) performed well, Henry was somehow outshine (as always), Cannavaro in his full action as an outstanding captain, their passing are excellent, their crosses are nice, some with injury problems (poor Viera), some get too rough and other hectic wild actions…I was really enjoy. I think everyone does.

Finale, we just have to put a stop since a month has ended for the soccer fan now. No staying up late for football and no mamak stall during the night (for the game). Everyone will afterwards resume with his/her normal life. Thank you for the previous month for essentially creates a healthy environment with one game, one nation, one excitement and one celebration through out the whole world. All in one…

Victory for Italy, Doom for Germany

The semi-final match between Italy-Germany in the World Cup 2006 was indeed a fascinating match to watch. Even more interesting, Italy won the game (they’ll facing either Portugal or France in final). After sleeping for about an hour or so, I woke up at around 3am to watch the live match from Westfalenstadion, Dortmund. Truly I must say that, chances for Italy was quite small if to compare to Germany (the home ground team) who get full supports from their fans. But still I just have faith for Italy. I love Azzurri since long time ago, when I first watch them played during the EURO 2000 (they lost to France in semi-final). How sad…during that time, David Trezeguet scored the golden goal for France which spoiled Italy’s dream to win the EURO. I remembered the looks on Francesco Toldo (a very talented keeper) plus other Italy player too while ‘taking’ their lost. Really I am. During that time also, I considered France has a better ‘luck’ than Italy. While, in the World Cup of 2002, again no luck for the Azzurri (been defeated to the South Korea in the penalty shoot-out plus not really outshine during the EURO 2004 either). Well, it’s a game by the way. The answer is just between two, either one be defeated or one with victory. That’s for sure. Still, as a devoted fan, I can feel the pain too.

So back to Germany 2006, most of the World Cup fan predicted that Germany would go to the final facing another giant team, Brazil (oopss…Brazil lost to France in quarter). But sadly to say, the prediction went wrong. I mean totally (sorry my dear). What can I say about it? But last night match, both team perform a highly skillful football. Of coz, Italy played very well last night. Instead of just keeping on defend; they actually give a counter-attack through out the game. I just can’t believe myself. And it did give Germany a pressure. Both team played consistently that make them both tight nil to nil and drag them to the extra time. I was so amazed and somehow worried about that game, where as usual I just hope for the penalty shoot-out. To me, play for the shoot-out will definitely a fair game. And I don’t mind if Italy lost in the penalty shoot-out but not with a goal. It should be tight. Suddenly, miracle happen, on the 119 minutes, Grosso, Italy defender, with his left-foot kick the ball passing Lehmann (Germany keeper) that make the Azzurri with one goal a head. What a nice goal. And it’s not just stop there, because a minute later, Del Piero (sharing a one-two passing) found a chance to put the ball again into the German’s net. Arrghh…I think Klinsmann will just have to accept the fact that their journey towards the world cup’s winner ends here. Still, two thumbs up for Germany for making the game challenging and interesting. It’s just that no luck for them this year.

P/s- Actually, there’s something about Italy. For me is about how they play. Always convenient with 4-4-2 structure, they defend more than attack. That’s why, if one noticed how Italy win the games with a very small number of goals. They aimed averagely…
