Interview: Murray Gell-Mann / Science NewsShortly before his 80th birthday, on September 15, the physics Nobel laureate Murray Gell-Mann spoke with Science News Editor in Chief Tom Siegfried about his views on the current situation in particle physics and the interests he continues to pursue in other realms of science. Gell-Mann is most ...

Top quark chefs -- symmetry breakingFermilab physicists are examining the production, properties, and decay of top quarks to gain the most complete picture of the particle possible. They compare their observations to predictions made in the Standard Model of physics and in theories that build on that model.

The secret lives of particles -- US LHC BlogWhat do quantum particles do when we're not looking? Probably not what you'd expect.\n\nWhile the mathematical formalism 'behind the scenes' is perfectly well-defined and the predictions by the theory are completely sensible (and rigorously tested), it is often difficult to interpret the ...

Is quantum mechanics messing with your memory? | Science | guardian.co.ukImagine if a cold cup of coffee spontaneously heated up as you watched. Or a cracked pane of glass suddenly un-broke. According to physicist Lorenzo Maccone at the Massachusetts Institute of Technology , you see things like this all the time – you just don't remember. In a paper published ...

Beyond space and time: Fractals, hyperspace and more - New Scientist(Image: Ryan Wills) We don't have any trouble coping with three dimensions – or four at a pinch. The 3D world of solid objects and limitless space is something we accept with scarcely a second thought. Time, the fourth dimension, gets a little trickier. But it's when we start to explore ...

Rewriting general relativity? Putting a new model of quantum gravity under the microscopeRewriting general relativity? Putting a new model of quantum gravity under the microscope Scientists are trying to figure out to what extent a new theory of quantum gravity will reproduce general relativity -- the theory that currently explains, to very high accuracy, how masses curve ...

Vanquishing infinity: Old methods lead to a new approach to finding a quantum theory of gravityVanquishing infinity: Old methods lead to a new approach to finding a quantum theory of gravity In the 1940s, Richard Feynman devised a graphical method for carrying out calculations. Bern et al. use different kinds of diagrams that permit large calculations. Owing to their resemblance to the ...

Blasting Neutrinos Under Wisconsin May Yield Big Payoff - washingtonpost.comScientists are playing an exotic game of pitch and catch between Illinois and Minnesota. Their catcher's mitt is solid iron, weighs 5,500 tons, and is parked in northern Minnesota in an abandoned iron mine. With millions of dollars from the federal stimulus package, construction crews are now ...
