” …….. Physicists from the ALICE detector team have been colliding lead nuclei together at CERN‘s Large Hadron Collider (LHC) in an attempt to recreate the conditions in the first few microseconds after the Big Bang. Early results have shown that the quark-gluon plasma created at these energies does not form a gas as predicted, but instead suggest that the very early universe behaved like a hot liquid. …… “
CERN completes transition to lead-ion running at the LHC
An event recorded by the ALICE experimentfrom the first lead-ion collisions, at a centre-of-massenergy of 2.76 TeV per nucleon pair.
Geneva, 8 November 2010. Four days is all it took for the LHC operations team at CERN1 to complete the transition from protons to lead ions in the LHC. After extracting the final proton beam of 2010 on 4 November, commissioning the lead-ion beam was underway by early afternoon. First collisions were recorded at 00:30 CET on 7 November, and stable running conditions marked the start of physics with heavy ions at 11:20 CET today.
“The speed of the transition to lead ions is a sign of the maturity of the LHC,” said CERN Director General Rolf Heuer. “The machine is running like clockwork after just a few months of routine operation.” ……………………. For detail Click below
” Nearly 20 years of hard work by hundreds of people have made this machine a dream come true. Today, the LHC has delivered its first high-energy collisions to the experiments. The new data will give us an unprecedented tool to understand the Universe we live in.”
“Collisions of 3.5 TeV beams, 7 TeV total energy, at the LHC, is very good news for the particle physics community. I hope that steady running at good luminosity will be achieved and that we may learn what the cosmological ‘dark matter’ is.” Jack Steinberger, Nobel Prize in Physics 1988

At its 153rd session today, the CERN1 Council heard that the Large Hadron Collider ended its first full period of operation in style on Wednesday 16 December. Collisions at 2.36TeV recorded since last weekend have set a new world record and brought to a close a successful first run for the world’s most powerful particle accelerator. The LHC has now been put into standby mode, and will restart in February 2010 following a short technical stop to prepare for higher energy collisions and the start of the main research programme.
Scientists in Australia have developed a new material that is sensitive to different wavelengths and polarizations of laser light and can store data in five dimensions. Conventional DVDs and CDs store data in two dimensions and holographic disks use three. The so-called 5-D disks have the potential of storing up to 10 TB on a single disk. …………
I was always OK in math. Actually I loved math, loved studying it, loved using it. I loved history. I was particularly in love with archaeology and linguistics. And I could discuss anything with my brother-archaeology, etymology, anything at all. ……………..
