Large Hadron Collider a.k.a. Atom Smasher

Large Hadron Collider : Teori Isra Mi'raj akan terbukti




“Large Hadron Collider adalah cincin “Akselerator Partikel” dan “Atom-Smasher” raksasa yg dibuat oleh Badan Riset Nuklir Eropa (CERN) dengan panjang keliling 27 km yg terletak pd kedalaman 175 meter dibawah tanah. Dibangun diantara perbatasan Perancis dan Swiss, cincin itu sendiri terdiri dari 9300 kumparan magnet superkonduktif dengan berat berton-ton yg dirangkai seperti sosis dan kemudian didinginkan dengan sekitar 96 ton helium cair.

Sampai saat ini Proyek LHC melibatkan sekitar 7000 org Ahli Fisika Partikel (hampir separo dari semua ahli fisika partikel di seluruh dunia) dari 80 negara dan telah menghabiskan biaya sekitar USD 5,8 miliar (sekitar Rp 53,3 triliun). Dan direncanakan pada bulan Agustus ini mesin tersebut mulai dinyalakan.

Cara Kerja LHC adalah :



LHC terdiri dari dua buah pipa cahaya yg berdekatan dimana masing-masing pipa berisi sekelompok proton yg “berlari” mengilingi cincin utama ( 27 km ) secara berlawanan arah. Setiap kelompok proton tersebut didorong” oleh mesin LHC sehingga bisa mengandung energi sebesar 7 Trilyun Volt (7 TeV). Pada 4 titik tertentu 2 pipa tersebut akan bersilangan satu sama lain sehingga 2 kelompok proton tadi akan saling bertabrakan dg total energi sebesar 14 TeV dan menghasilkan 600 juta partikel per detik.

Pada titik-titik tabrakan tersebut dipasang detektor-detektor raksasa yg akan mencatat semua serpihan partikel super kecil yg dihasilkan pada setiap tabrakan. Saking besarnya salah satu dari detektor tersebut konstruksi bisa dipakai untuk membangun satu Menara Eiffel baru.


Semua ini punya satu tujuan dasar:
“Untuk Mengulang Kembali Kejadian Awal Terbentuknya Alam Semesta Kita atau BIG BANG Dalam Skala Mikro !”







Large Hadron Collider dibangun untuk menjawab berbagai misteri terbesar dalam alam semesta, yaitu :

Bagaimana Alam Semesta Bisa Terbentuk Sampai Bisa Seperti Sekarang Ini ?
Memang para ahli sudah sepakat bahwa alam semesta terbentuk akibat peristiwa “Big Bang” tapi mereka belum benar-benar memahami bagaimana dan mengapa alam semesta bisa berkembang seperti sekarang ini. Dengan mesin LHC bisa diketahui apa yg terjadi [b]sepersejuta detik[/] setelah big bang terjadi.

Para ahli berharap akan bisa melihat partikel paling eksotis yaitu “Partikel Higg Boson” atau populer disebut dengan “Partikel Tuhan”. Mereka sdh punya dugaan sendiri tapi para ahli juga berharap pada apa yg “tidak terduga”.

Macam Apa Alam Semesta Kita Ini ?
Banyak ahli fisika yg percaya bahwa alam semesta kita tidak hanya terdiri dari 3 dimensi (ruang dan waktu) seperti yg kita pahami saat ini. Bahkan ada yg menyatakan bahwa alam semesta sebenarnya terdapat 10 Dimensi.

Dimana anti-materi berada?
Big Bang menghasilkan “materi” (zat) dan anti-materi dengan jumlah yg sama, tetapi kita hanya bisa melihat “materi” saja. Apa yg terjadi dengan anti-materi ? Dengan percobaan LHC bisa dipelajari perbedaan yg hampir tidak terlihat antara partikel materi dan anti-materi tersebut.

Kenapa Partikel Memiliki Massa ?
Partikel cahaya atau Photon tidak memiliki massa. Sedangkan partikel zat lain seperti elektron dan quarks memiliki massa dan para ahli fisika tidak tahu pasti kenapa bisa begitu.

Terbuat Dari Apakah Alam Semesta Kita Ini ?
Para ahli hanya mengetahui 4% materi yang menyusun alam semesta kita sedangkan 96% masih merupakan misteri besar yg populer disebut “Dark Energy”.

Teori dari “Super Simetri” berpendapat bahwa semua partikel yg tercipta di alam semesta mempunyai ’super-partner” sendiri-sendiri. Kalau super-partner ini ada LHC akan mampu mendeteksinya dan mungkin bisa menjelaskan mistery terbesar alam semesta – Dark Matter dimana ada yg berpendapat kalau Dark Matter tersusun dari “Partikel Supersimetris “.

Kogan Agora: Ponsel Android Kedua

Mulai hari ini, salah satu perusahaan pembuat ponsel asal Australia Kogan mulai menerima pesanan untuk ponsel Android kedua dunia setelah T-Mobile G1 yaitu Kogan Agora Pro (KAP) yang akan debut di Australia pada tanggal 29 Januari dengan harga sekitar US$256. Tidak seperti G1, ponsel ini tidak terkunci untuk penyedia layanan apapun. 

Hal yang benar-benar menarik dari generasi kedua ini adalah kemiripannya dengan Blackberry. Apakah kombinasi 
keyboard QWERTY ala Blackberry dengan aplikasi-aplikasi yang bisa diunduh gaya iPhone ini bisa menjadi kunci sukses? 



Selain KAP, ponsel ini juga memiliki versi murah Kogan Agora (KA) juga akan tersedia dengan harga US$192. Bedanya dengan KAP adalah tipe ini tidak memiliki kamera, Wi-Fi atau GPS. Baik KAP maupun KA mengemas prosesor 624 MHz, RAM 128 MB, 
slot microSD, 3G, layar sentuh berukuran 2,5 inci dengan resolusi 320x240, Bluetooth, tombol navigasi dan keyboard QWERTY penuh.

Terbaik Dari Dua Dunia

Apa yang paling menarik tentang Kogan Agora, setidaknya menurut spesifikasinya adalah janji untuk memberikan kombinasi aplikasi dan musik dari iPhone dalam ponsel dengan keypad dan ukuran yang mirip Blackberry. 

Banyak orang yang walaupun menyukai iPhone, harus belajar membiasakan diri dulu untuk menggunakan layar sentuhnya. Beberapa pengguna bahkan merasa kesulitan dengan sistem tersebut, apalagi bekas pengguna Blackberry atau Nokia E61 yang sudah terbiasa dengan pengalaman mengetik di Blackberry. Beralih ke iPhone adalah sesuatu yang harus dipikirkan dua kali oleh pengguna tipe ini. 

Walaupun mereka akan mendapatkan kombinasi multimedia dan aplikasi keren lainnya di iPhone, mereka harus mengorbankan kebiasaan mengetik dan produktivitas mereka. Bagi para pengguna email dan pengetik yang berat, melepaskan 
keyboard tampaknya merupakan taruhan yang sulit. 

Jadi, apakah kombo ini bisa menjadi awal kesuksesan Android? (G1 juga cukup sukses di AS) Kita tunggu saja apakah ponsel ini dapat mendongkrak status Android lebih tinggi lagi di industri ponsel pintar.

Google Chrome no longer in beta



Google has removed the beta tag from its Chrome browser - just 100 days after the software was first launched. It’s a staggeringly fast turnaround for a company that is now almost legendary for leaving products to gestate in beta for years. GMail remains in beta more than four years after it was first launched, while the photo editing software Picasa only recently dropped its beta status for the first time since it was acquired by Google in 2004. The search giant claims the removal of Chrome’s beta tag is an indication of its maturity. “We have removed the beta label as our goals for stability and performance have been met but our work is far from done,” the company claims in a blog post.
However, critics are suggesting that Google has whipped off the beta tag in an attempt to boost the browser’s disappointing market share. Net Applications claims Chrome commanded only 0.83% of the browser market in November - a mere 0.05% increase on its first month of availability in September. Google may be hoping that companies will be more inclined to install Chrome now that the beta tag has been removed. Last month, the company said it would also pay PC makers to bundle Chrome on new PCs. Google claims Chrome’s performance has improved significantly since September. “Since the first beta, the V8 JavaScript engine runs 1.4 times faster on the SunSpider benchmark and 1.5 times faster on the V8 benchmark - and there is more speed to come,” it claims. The company also says it’s addressed glitches with video and audio playback.

Yahoo rolls out new social email



Yahoo Inc. is getting more open and more social. The Internet giant said Monday that it was rolling out features designed to make its e-mail service and other properties more like popular social networking sites Facebook and MySpace. The features, more than a year in the making, are the brainchild of Yahoo Chief Executive Jerry Yang, who previewed them in a keynote speech at the Consumer Electronics Show in January. Since becoming CEO in June 2007, Yang pushed Yahoo to open up to outside content and to tap into the underlying social connections in its properties.
Yahoo, which is weathering a wrenching downturn including layoffs that began last week, hopes to turn the tide with new features that help its 275 million e-mail users form bonds with friends, colleagues and family to share information and track one another’s activities. The Sunnyvale, Calif., company is also opening its e-mail service to features created by other companies such as online movie site Flixster. The strategy will outlast Yang, who is stepping down once his successor is found. That search is in its early stages, with several candidates being considered. A final decision is expected early next year. Yahoo plans to incorporate the new features into its overhauled home page, its toolbar for browsing the Web and personalized home pages. What isn’t clear is how these new features will help Yahoo make more money from its giant Web audience.

World AIDS Day

It's World AIDS Day, so how fitting that New York City -- which along with San Francisco was most certainly Ground Zero of the early days of AIDS -- has finally gotten a fitting monument to the more than 60,000 city residents we have lost to this heinous disease. (Can you believe one didn't already exist? It seems every time a plan was hatched the organizers would pull back knowing that money was better-spent on AIDS research.)

[world_aids.gif]

Also on this 20th observance of World AIDS Day, we find ourselves in a cautiously optimistic position. While new infections in younger gay men and some minority groups are up and the search for a vaccine has stalled, a new study suggests that immediate treatment after testing positive for AIDS -- rather than waiting for immune depression to kick in -- could not only help people live longer and healthier lives, it may drastically reduce the spread of the virus. This "thought experiment," along with an incoming president who actually understands the importance of AIDS education and prevention -- and that condoms ARE pro-life -- give me hope for the next four years. On a more personal note, having three good friends who are truly "living with HIV" -- not "dying of AIDS" -- is all the evidence I need that things are much different than they were when World AIDS Day began in 1988.
