According to Einstein’s theory of general relativity, a moving mass should create another field, called gravitomagnetic field, besides its static gravitational field. This field has now been measured for the first time and to the scientists’ astonishment, it proved to be no less than one hundred million trillion times larger than Einstein’s General Relativity predicts.
This gravitomagnetic field is similar to the magnetic field produced by a moving electric charge (hence the name “gravitomagnetic” analogous to “electromagnetic”). For example, the electric charges moving in a coil produce a magnetic field – such a coil behaves like a magnet. Similarly, the gravitomagnetic field can be produced to be a mass moving in a circle. What the electric charge is for electromagnetism, mass is for gravitation theory (the general theory of relativity).
“We ran more than 250 experiments, improved the facility over 3 years and discussed the validity of the results for 8 months before making this announcement. Now we are confident about the measurement,” says Tajmar. They hope other physicists will now conduct their own versions of the experiment so they could be absolutely certain that they have really measured the gravitomagnetic field and not something else. This may be the first empiric clue for how to merge together quantum mechanics and general theory of relativity in a single unified theory.

Political, religious and sexual behaviors may be reflections of intelligence, a new study finds.
Evolutionary psychologist Satoshi Kanazawa at the the London School of Economics and Political Science correlated data on these behaviors with IQ from a large national U.S. sample and found that, on average, people who identified as liberal and atheist had higher IQs. This applied also to sexual exclusivity in men, but not in women. The findings will be published in the March 2010 issue of Social Psychology Quarterly.
Wonderful steak lunch at Rowley’s in town and birthday treats followed by the loveliest gifts and more treats from the crew. Dressing room decked out with balloons etc, and some really touching prezzies. On top of that a zillion birthday wishes from Twitter. Lor’ Lu’mme. Best birthday ever. Rather sleepy though: wine and champagne and cake has me now dozing off into my steamer as I type.
One particularly impressive gift was this Derren Brown Enigma action figure, made by Jennie and Iain. Amazing! I do adore my group of friends. If it’s your birthday too, have a wonderful one.
Last night (Fri) was terrific: Thursday’s first half a little under-par mainly due to nervous volunteers. Which can’t be helped, and the second was much better. Tomorrow Buxton!
On the road again…
Coming in March is a new series about the solar system from wonderful Professor Brian Cox. I’ll be watching.
“Venice could be saved from sinking into the sea by releasing fat globules similar to olive oil into the water that are ‘programmed’ to form limestone reefs, say architects.
The novel solution for the threatened Italian city, built on silty islands on the Adriatic coast, uses experimental technology that they have dubbed “smart salad dressing”.
It would work by releasing oil droplets into the water that are chemically programmed to react with carbon dioxide in the water, precipitating an artificial limestone carbonate.
Two British architects at University College, London, are among those behind the Future Venice project.
Rachel Armstrong, from UCL’s Bartlett School of Architecture, explained the “protocell” technology.
She said: “This technology is based on the chemistry of oil and water and has the special property of transforming carbon dioxide into a limestone-like substance.”
The globules would form “solid pearls” of artificial limestone that could protect buildings from future damage, she argued. ”
