Einstein@Home - Search for PULSARS With Gravity Wave Dectors at Home
Einstein@home is a program that uses your computer´s idle time to search for spinning neutron stars (also called pulsars) using data from the LIGO and GEO gravitational wave detectors. Einstein@home is a World Year of Physics 2005 project supported by the American Physical Society (APS) and by a number of international organizations.

After several months of testing, we are now ´throwing open the doors´ for general participation. If you would like to take part, please use the Create account link to create an account, and follow the instructions. Einstein@home is available for Windows, Linux and MacOS X computers.

This first production run of Einstein@home carries out a search for pulsars over the entire sky, using the most sensitive 600 hours of data from LIGO´s third science run, S3.

Bruce Allen, Professor of Physics, U. of Wisconsin - Milwaukee
Einstein@home Leader for the LIGO Scientific Collaboration



Feb 19, 2005
Einstein@Home was officially launched this morning at the American Association for the Advancement of Science (AAAS) meeting in Washington, DC, USA.

Feb 14, 2005
For testing purposes, in anticipation of our public launch, we will be enabling account creation for some unannounced periods this week. If you are interested in joining Einstein@Home, please try the Create Account link.

Re: Einstein@Home - Search for PULSARS With Gravity Wave Dectors at Home
How your home computer could prove Einstein right
By Mark Henderson, Science Correspondent (Nov., 2004)


THOUSANDS of British computer-users will join the search for one of the most mysterious forces in the Universe next year, as part of celebrations for the centenary of Albert Einstein’s greatest discoveries.

The Einstein@home project will tap into the spare capacity of home and office computers to analyse data that could confirm the existence of gravitational waves that Einstein predicted in his general theory of relativity, but which have never been detected.

By downloading a simple screensaver featuring the most famous face in physics, computer-users can link to a global network that will sift raw results from two observatories hunting for the elusive waves.

Whenever the computer is idle and the screensaver starts up, its processing power will be added to the gravitational wave hunt. The combined capacity of hundreds of thousands of small computers joined in this way is much greater than anything normally available to scientists.

The scheme is modelled on SETI@home, a similar “distributed computing” scheme used by the Search for Extra-Terrestrial Intelligence to examine raw radio signals from space that would otherwise be impossible to process. A team at the University of Oxford is using similar methods to screen chemical compounds for their potential as drugs for treating leukaemia.

Einstein@home is one of dozens of initiatives starting in January under Einstein Year, which marks the centenary of the Swiss-born physicist’s annus mirabilis of achievement. In 1905, while working at the Swiss patent office in Berne, Einstein published three seminal papers that were to revolutionise modern physics. His analysis of the photoelectric effect laid the foundations of quantum mechanics and his investigations of Brownian motion proved the existence of atoms. His special theory of relativity mapped the relation of space and time and gave the world the equation E=mc².

Einstein Year will also involve a “Lab in a Lorry”, which will tour Britain staging physics experiments, public participation experiments at the Glastonbury Festival and a special dance production by the Rambert Dance Company. A party for 400 children, explaining the physics of football, will be held at Ipswich Town Football Club in March.

Gravitational waves are a great discovery waiting to happen, according to experts in the field, and the launch of Einstein@home means that members of the public will be able to claim a share of the credit if and when they are found. Caitlin Watson, the Einstein Year project manager at the Institute of Physics, said: “You could, in theory, be the person to discover a gravity wave, if it’s your computer that helps to track them down.” The waves are ripples in the fabric of space and time produced by violent energetic events such as exploding supernovae.

PHYSICAL FEATS

Brownian motion, 1905

This effect takes its name from Robert Brown, who in 1827 observed that pollen grains in water do not stand still, but jiggle about. Einstein explained in 1905 that it is due to movement of the water molecules. The experiments proved the existence of atoms

Photoelectric effect, 1905

Light generates an electric current when shone on metal — but only in certain colours. Blue light does this, but red light does not. Einstein’s experiments showed that this is because light is carried by particles known as photons, as well as waves. The discovery led to quantum theory

Special relativity, 1905

If the speed of light is constant, measurements of distance and time must vary according to how fast you are travelling. Thus the equation E=mc²

General relativity, 1915-16

An expanded version of the special theory, which includes the effect of gravity on the shape and flow of time...

Einstein@Home
Albert Einstein suggested long ago that we are adrift in a universe filled with waves from space. Colliding black holes, collapsing stars, and spinning compact celestial objects such as pulsars create ripples in the fabric of space and time that subtly distort the world around us. These gravitational waves have eluded scientists for nearly a century. Exciting new experiments may let them catch the waves in action and open a whole new window on the universe - but they need your help to do it!

Having to keep up with each other by telephone contact sounds awful. I hope you get to see your little daughter soon BF. Even though I was single parent from when my daughter was 4 I got to keep ´em around until they abandoned me to rock out 600 miles away. They both keep a room for me to crash in anytime though, so its all good.

Oh I see her once a week -- sometimes more. Depending on the wife´s mood. They only live about a mile away...

In response, I told her: "I miss you 100-miles-alot too."

She then said: "Well if you miss me 100-miles-alot then ... then buy Justin some new toys."

Justin´s the cat - he´s still living here.

Will humankind ever master the control of gravity? If so, how will we be able to control gravity in useful ways, for instance for space propulsion? The answer may involve gravitational waves. Just as alternating current, or AC, unlocked the utility of electricity a century ago, alternating gravity, dubbed "AG", may be the key to unlocking the useful control of gravity in the century ahead.

"This says that gravity, the shape of space-time, is equal to a constant K, times T, the mass-energy tensor, which describes the shape (or distribution) of mass or energy in space. In other words, gravity, the shape of space-time, depends only on mass and energy. "

G = K*T ? Where is consciousness in all this? What describes the movement of the mass or energy distributed in space? Not just the movement of galaxies and stars or mitochondria in cell but the movement in your "mind"? Surely not Einsteins less famous formula. I bet G has a lot to do with it though.

BF I think RRS may be a Synesthete!

-------
Synesthesia: Hearing Colors

Synesthesia is a condition in which the real information of one sense is accompanied by a perception in another sense. A person may see colors when hearing a sound or may experience a smell when seeing a certain color. Such a person is called a synesthete. There is much to be learned about this phenomenon.

Questions you may have include:

What type of things do people experience or sense?
Are such people crazy?
How is this explained?


Many brilliant people have been synesthetes, including:

Novelist Vladimir Nabokov saw different colors for each letter in the alphabet. His mother was also a synesthete.
Composer Franz Liszt saw colors when hearing musical notes.
Physicist Richard Feyman saw colors in his physics equations.
Abstract painter Wassily Kandinsky saw the colors for his paintings when hearing music.

I´ll tell you one thing. Creative synesthetes have advantage when it comes to surrealism.


Joanne Innis was around 5 years old when she asked her mother, "How come if you and Aunt Pat are sisters, you´re red and she´s brown?"

When Glenda Larcombe hears a truck backing up, making a beep-beep-beep sound, she "sees" the beeps as a series of red dots.

And when psychologist Thomas Palmeri gives one of his test subjects a difficult test -- to spot a tiny "2" on a computer screen scattered with tiny "5s" -- the man finds it instantly: To him, the "2" shows up bathed in a different color.
