Samsung Galaxy Note II

The Samsung Galaxy Note II is a smartphone–tablet computer hybrid designed, developed and marketed by Samsung. It is the successor to the Samsung Galaxy Note, and is the third device of the company's Note series, which places emphasis on the use of a stylus. Employing a 1.6 GHz quad-core processor, the device sports a 5.55-inch (141 mm) diagonal display with 720p resolution, 2 GB of RAM, and a maximum of 64 GB storage. IT is the first Samsung phone to come with Android version 4.1 "Jelly Bean" as standard
The Galaxy Note II was unveiled 29 August 2012 at the Berlin Radio Show.
Given the larger than average screen on this smartphone, it has been referred to in some circles as a smartphone - tablet computer hybrid known colequially as a "phablet". Samsung however officially markets this device as a Smartphone.

DARK ENERGY-REALITY


Dark Energy Is Real, Say Astronomers


Dark energy, a mysterious substance thought to be speeding up the expansion of the Universe is really there, according to a team of astronomers at the University of Portsmouth and LMU University Munich.
After a two-year study led by Tommaso Giannantonio and Robert Crittenden, scientists conclude that the likelihood of its existence stands at 99.996 per cent. Their findings are published in the Monthly Notices of the Royal Astronomical Society.
Professor Bob Nichol, a member of the Portsmouth team, said: "Dark energy is one of the great scientific mysteries of our time, so it isn't surprising that so many researchers question its existence.
"But with our new work we're more confident than ever that this exotic component of the Universe is real -- even if we still have no idea what it consists of."
Over a decade ago, astronomers observing the brightness of distant supernovae realised that the expansion of the Universe appeared to be accelerating. The acceleration is attributed to the repulsive force associated with dark energy now thought to make up 73 per cent of the content of the cosmos. The researchers who made this discovery received the Nobel Prize for Physics in 2011, but the existence of dark energy remains a topic of hot debate.
Many other techniques have been used to confirm the reality of dark energy but they are either indirect probes of the accelerating Universe or susceptible to their own uncertainties. Clear evidence for dark energy comes from the Integrated Sachs Wolfe effect named after Rainer Sachs and Arthur Wolfe.
The Cosmic Microwave Background, the radiation of the residual heat of the Big Bang, is seen all over the sky. In 1967 Sachs and Wolfe proposed that light from this radiation would become slightly bluer as it passed through the gravitational fields of lumps of matter, an effect known as gravitational redshift.
In 1996, Robert Crittenden and Neil Turok, now at the Perimeter Institute in Canada, took this idea to the next level, suggesting that astronomers could look for these small changes in the energy of the light, or photons, by comparing the temperature of the radiation with maps of galaxies in the local Universe.
In the absence of dark energy, or a large curvature in the Universe, there would be no correspondence between these two maps (the distant cosmic microwave background and relatively closer distribution of galaxies), but the existence of dark energy would lead to the strange, counter-intuitive effect where the cosmic microwave background photons would gain energy as they travelled through large lumps of mass.
The Integrated Sachs Wolfe effect was first detected in 2003 and was immediately seen as corroborative evidence for dark energy, featuring in the 'Discovery of the year' in Science magazine. But the signal is weak as the expected correlation between maps is small and so some scientists suggested it was caused by other sources such as the dust in our galaxy. Since the first Integrated Sachs Wolfe papers, several astronomers have questioned the original detections of the effect and thus called some of the strongest evidence yet for dark energy into question.

In the new paper, the product of nearly two years of work, the team have re-examined all the arguments against the Integrated Sachs Wolfe detection as well as improving the maps used in the original work. In their painstaking analysis, they conclude that there is a 99.996 per cent chance that dark energy is responsible for the hotter parts of the cosmic microwave background maps (or the same level of significance as the recent discovery of the Higgs boson).
"This work also tells us about possible modifications to Einstein's theory of General Relativity," notes Tommaso Giannantonio, lead author of the present study.
"The next generation of cosmic microwave background and galaxy surveys should provide the definitive measurement, either confirming general relativity, including dark energy, or even more intriguingly, demanding a completely new understanding of how gravity works."

install windows on USB and carry in pocket

I am going to explain how to install Windows on a pen drive/usb..
this a very useful hack..u can carry and work in your customized window wherever u go..

Requirements to install Windows on USB:
# An USB flash drive with a minimum of 6 GB disk space to install Windows 7 or Vista. You can use a 4 GB drive to install XP.
# Bootable Windows 7 USB or DVD.
# Free time
So let’s begin with the installing Windows 7 on USB procedure:
1. First of all, connect your USB to the machine and backup all the data from the USB drive.
2. Download VirtualBox portable, double-click on the executable file and extract the contents to your USB.
install windows 7 on usb
3. Now, go to the VirtualBox portable folder in USB, and execute the Portable-VirtualBox (.exe) file.
4. From here onwards, you need to follow the onscreen procedure to create a virtual disk and install Windows 7 on USB. Follow the install Windows 7 on VirtualBox guide to complete the process.
5. Once you finish the installation process, you can safely close VirtualBox and remove your USB drive.
6. You can now use this Windows 7 USB drive on any Windows machine that you want. To use Windows 7 on other machine, connect the Windows 7 USB, open USB drive, and run portable-VirtualBox file.
